Abstract
OBJECTIVE To explore the impact of minimally invasive surgery on treating patients with early cervical adenocarcinoma (CA). METHODS From April 2016 to December 2019, patients with early CA and underwent surgery were prospectively included in this study. They were randomly divided into 2 groups: the minimally invasive surgery (MIS) group and conventional laparotomy (CL) group. The baseline characteristics, pathological features, surgical related parameters, serum tumor markers, complications and prognosis were analyzed and compared between the 2 groups. The risk factors for disease free survival (DFS) and overall survival (OS) were also analyzed with logistic regression analyses. RESULT The baseline characteristic and pathological features had no statistical difference between the 2 groups. The mean operation duration in MIS group was significantly longer than CL group (262.39 ± 34.98 vs 241.29 ± 36.98 min, P < 0.001). The intraoperative blood loss volume (189.87 ± 23.87 vs 306.87 ± 24.98 mL, P < 0.001), postoperative anal exhaust time (45.98 ± 4.39 vs 59.87 ± 4.87 days, P < 0.001), catheter removal time (18.29 ± 3.21 vs 21.53 ± 3.19 days, P < 0.001) and length of hospital stay (12.98 ± 2.09 vs 16.98 ± 2.32 days, P < 0.001) were significant lower in MIS group. The serum tumor markers decreased significantly postoperative in both groups with no different levels between the 2 groups. The incidence of complications had no difference between the 2 groups except lymphocysts (P = 0.023). After mean follow up time for 4.23 ± 0.34 years, the DFS rate and OS rate also had no statistical difference between the 2 groups (P = 0.069 and 0.151, respectively). CONCLUSION Extensive hysterectomy with MIS was equally efficacy and safe to CL.

Abstract
Background T-cell immunoglobulin mucin-1 (TIM-1) has been reported to be associated with the biological behavior of several malignant tumors; however, it is not clear whether it has a role in cervical cancer (CC). Methods TIM-1 expression in cervical epithelial tumor tissues and cells was detected by immunohistochemistry or real-time quantitative-PCR and western blotting. CC cells from cell lines expressing low levels of TIM-1 were infected with lentiviral vectors encoding TIM-1. Changes in the malignant behavior of CC cells were assessed by CCK-8, wound healing, Transwell migration and invasion assays, and flow cytometry in vitro; while a xenograft tumor model was established to analyze the effects of TIM-1 on tumor growth in vivo. Changes in the levels of proteins related to the cell cycle, apoptosis, and Epithelial-mesenchymal transition (EMT) were determined by western blotting. Results TIM-1 expression was higher in CC tissues, than in high grade squamous intraepithelial lesion, low grade squamous intraepithelial lesion, or normal cervical tissues, and was also expressed in three CC cell lines. In HeLa and SiHa cells overexpressing TIM-1, proliferation, invasion, and migration increased, while whereas apoptosis was inhibited. Furthermore, TIM-1 downregulated the expression of p53, BAX, and E-cadherin, and increased cyclin D1, Bcl-2, Snail1, N-cadherin, vimentin, MMP-2, and VEGF. PI3K, p-AKT, and mTOR protein levels also increased, while total AKT protein levels remained unchanged. Conclusions Our study indicated that TIM-1 overexpression promoted cell migration and invasion, and inhibited cell apoptosis in CC through modulation of the PI3K/AKT/p53 and PI3K/AKT/mTOR signaling pathways, and may be a candidate diagnostic biomarker of this disease.

Abstract
Stimulus-sensitive, nanomedicine-based photosensitizer delivery has an opportunity to target tumor tissues since oxidative stress and the expression of molecular proteins, such as CD44 receptors, are elevated in the tumor microenvironment. The aim of this study is to investigate the CD44 receptor- and reactive oxygen species (ROS)-sensitive delivery of nanophotosensitizers of chlorin e6 (Ce6)-conjugated hyaluronic acid (HA) against HeLa human cervical cancer cells. For the synthesis of nanophotosensitizers, thioketal diamine was conjugated with the carboxyl group in HA and then the amine end group of HA-thioketal amine conjugates was conjugated again with Ce6 (Abbreviated as HAthCe6). The HAthCe6 nanophotosensitizers were of small diameter, with sizes less than 200. Their morphology was round-shaped in the observations using a transmission electron microscope (TEM). The HAthCe6 nanophotosensitizers responded to oxidative stress-induced changes in size distribution when H2O2 was added to the nanophotosensitizer aqueous solution, i.e., their monomodal distribution pattern at 0 mM H2O2 was changed to dual- and/or multi-modal distribution patterns at higher concentrations of H2O2. Furthermore, the oxidative stress induced by the H2O2 addition contributed to the disintegration of HAthCe6 nanophotosensitizers in morphology, and this phenomenon accelerated the release rate of Ce6 from nanophotosensitizers. In a cell culture study using HeLa cells, nanophotosensitizers increased Ce6 uptake ratio, ROS generation and PDT efficacy compared to free Ce6. Since HA specifically bonds with the CD44 receptor of cancer cells, the pretreatment of free HA against HeLa cells decreased the Ce6 uptake ratio, ROS generation and PDT efficacy of HAthCe6 nanophotosensitizers. These results indicated that intracellular delivery of HAthCe6 nanophotosensitizers can be controlled by the CD44 receptor-mediated pathway. Furthermore, these phenomena induced CD44 receptor-controllable ROS generation and PDT efficacy by HAthCe6 nanophotosensitizers. During in vivo tumor imaging using HeLa cells, nanophotosensitizer administration showed that the fluorescence intensity of tumor tissues was relatively higher than that of other organs. When free HA was pretreated, the fluorescence intensity of tumor tissue was relatively lower than those of other organs, indicating that HAthCe6 nanophotosensitizers have CD44 receptor sensitivity and that they can be delivered by receptor-specific manner. We suggest that HAthCe6 nanophotosensitizers are promising candidates for PDT in cervical cancer.

Abstract
PURPOSE To explore the regulatory effect of let-7a-5p/TGFBR1/Smad3 on the proliferation activity of cervical cancer cells. METHODS The difference in let-7a-5p expression between normal people and patients with cervical cancer was detected by miREIA assay. The differences of let-7a-5p expression between cervical cancer cell line C33a and adjacent normal epithelial cell line HUCEC were determined by qRT-PCR. RESULTS miREIA result showed that let-7a-5p concentrations were 178.5 ± 24.3 μg/L in healthy individuals and 106.1 ± 14.8 μg/L in cervical cancer patients (P = 0.0002). qRT-PCR showed that let-7a-5p in cervical cancer tissue (0.57 ± 0.03) was lower than that in adjacent normal tissue (0.84 ± 0.04, P = 0.0107). Compared with normal cervical epithelial cells (HUCEC), the expression of let-7a-5p was lower in cervical cancer cells (C33a, Hela, P = 0.0001). The results of CCK-8 and EDU detection showed that activation of let-7a-5p inhibited the proliferation of C33a (P = 0.00130, P << 0.0001) and Hela (P = 0.00254, P = 0.0066) cells. According to the analysis using Starbase V2.0 online database, let-7a-5p could target TGFβR1 in cervical cancer cell lines, and the let-7a-5p mimic reduces the mRNA expression level of TGFβR1 in cervical cancer cell C33a (P = 0.0067). Western blot results showed that TGFBR1 expression significantly decreased in cervical cancer cells after let-7a-5p mimic treatment (P = 0.0048) and significantly increased after let-7a-5p mimic inhibitor treatment (P = 0.0003). CONCLUSIONS let-7a-5p represents the independent novel anti-oncogenes in cervical cancer, which can regulate TGF-β1/TGFBR1/pSmad3 cell pathway and interfere with the proliferation of cervical cancer cells. Therefore, let-7a-5p can serve as a novel potential therapeutic target for the treatment of cervical cancer.

Abstract
INTRODUCTION Gynaecology cancers, including ovarian (OC), endometrial (EC), and cervical (CC), are prevalent with high mortality. Sarcopenia is found in 38.7% of cancer patients, adversely affecting prognosis. Computed tomography (CT) is performed routinely in oncology, yet CT assessments of sarcopenia are not commonly used to measure prognosis. This systematic review and meta-analysis aimed to evaluate the prognostic potential of pre-treatment sarcopenia assessments on overall survival (OS) and progression free survival (PFS) in gynaecology cancer. METHODOLOGY Four electronic databases were systematically searched from 2000 to May 2020 in English: Ovid Medline, EMBASE, Web of Science, and CINAHL plus. Titles and abstracts were screened, eligible full-texts were reviewed, and data from included studies was extracted. Meta-analyses were conducted on homogenous survival data, heterogenous data were narratively reported. RESULTS The initial search yielded 767 results; 27 studies were included in the systematic review (n = 4286), all published between 2015 and 2020. Meta-analysis of unadjusted results revealed a negative effect of pre-treatment sarcopenia on OS in OC (HR: 1.40, 1.20-1.64, p < 0.0001) (n = 10), EC (HR: 1.42, 0.97-2.10, p = 0.07) (n = 4) and CC (HR: 1.10, 0.93-1.31, p = 0.28) (n = 5), and a negative effect on PFS in OC (HR: 1.28, 1.11-1.46, p = 0.0005) (n = 8), EC (HR: 1.51, 1.03-2.20, p = 0.03) (n = 2) and CC (HR: 1.14, 0.85-1.53, p = 0.37) (n = 2). Longitudinal analysis indicated negative effects of muscle loss on survival. Overall, there was a high risk of bias. CONCLUSION Pre-treatment sarcopenia negatively affected survival in gynaecology cancers. Incorporating such assessments into cancer management may be beneficial. Heterogeneity in sarcopenia assessments makes data interpretation challenging. Further research in prospective studies is required.

Abstract
The prognosis of patients with liver metastasis of cervical cancer is poor with an extremely short survival period, and there have been no reports of cervical cancer complicated by portal vein tumor thrombosis (PVTT). We report a case of cervical cancer developing liver metastasis with PVTT. A 49-year-old woman developed liver metastasis from cervical cancer with PVTT. The primary tumor was locally controlled with multidisciplinary treatment, including systemic therapy, surgical resection, and radiation. However, her follow-up abdominal computed tomography results showed two irregular tumors in the liver's segments 2 and 6. From the latter lesion, a low-density filling defect extended to the posterior branch of the portal vein, suggesting PVTT. Hepatectomy of the two metastases was performed to prevent portal vein obstruction during subsequent chemotherapy. Pathological analysis revealed metastatic squamous cell carcinoma from cervical cancer that developed a tumor thrombus at the posterior branch of the portal vein. The patient received adjuvant chemotherapy, but died 10 months after surgery for recurrent liver metastasis. We present the first case of liver resection for liver metastasis from cervical cancer with PVTT. Although cervical cancer with PVTT is associated with a poor prognosis, surgical resection is a feasible option for preventing portal vein obstruction during subsequent chemotherapy.

Abstract
Uterine cervical carcinoma is an important type of cancer among Ecuadorian women, especially in adult women. Survival rates have improved with the development of radiotherapy, surgical techniques, and chemotherapy. However, recurrence and/or metastasis are not unusual phenomena. Frequent sites of metastasis are the lungs, regional lymph nodes, and bones. Atypical locations can also occur on solid organs, such as adrenal glands. Treatment for the rare complication that is adrenal metastasis is individualized, it can include surgical resection, chemotherapy, local ablation, or different types of radiotherapy. We aimed to report a case of an Ecuadorian woman from Quito city with a diagnosis of cervical carcinoma diagnosed in 2009, treated surgically and with adjuvant chemotherapy. Her progression was monitored with medical controls with no recurrence until 2018, when she relapsed with a metastatic invasion of the pelvic ganglia and the surroundings of the abdominal aorta, with a histopathologic diagnosis of adenocarcinoma. She was then treated with chemotherapy and radiotherapy until June 2019. In 2020, she went through a splenectomy and left adrenalectomy to treat vascular thrombosis. In 2021, 37 x 15 mm mass was discovered in the surgical bed of the previously removed adrenal gland. It was treated as an oligometastatic carcinoma with stereotactic body radiotherapy (SBRT) by a linear accelerator.

Abstract
Arctiin, a lignan glycoside, is isolated from Arctium lappa L. The anticancer effects of arctiin have been demonstrated in several studies. However, no research has been conducted on the anti-migration effect of arctiin in cervical cancer cells. The present study examined the effects of arctiin on cervical cancer cells and investigated the possible molecular mechanism. We demonstrated that arctiin exhibited low cytotoxicity and significantly inhibited cell migration and invasion in human cervical cancer cells. The S100A4 protein expression and mRNA levels were significantly reduced in HeLa and SiHa cells with arctiin treatment. Furthermore, silencing S100A4 by using small interfering RNA reduced cell migration, while overexpression of S100A4 mitigated the migration inhibition imposed by arctiin in cervical cancer cells. Western blotting revealed that arctiin significantly reduced phosphoinositide 3-kinase (PI3K) and phosphorylation of Akt in cervical cancer cells. Moreover, selective Akt induction by an Akt activator, SC-79, reverted cervical cancer cell migration and S100A4 protein expression, which were reduced in response to arctiin. Taken together, these results suggest that arctiin inhibits cervical cancer cell migration and invasion through suppression of S100A4 and the PI3K/Akt pathway.

The role of NFATc1/c-myc/PKM2/IL-10 axis in activating cervical cancer tumor-associated M2 macrophage polarization to promote cervical cancer progression. Exp Cell Res 2022; 413:113052. [PMID: 35122827 DOI: 10.1016/j.yexcr.2022.113052] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 01/29/2022] [Accepted: 02/01/2022] [Indexed: 12/20/2022]
Abstract
Nuclear factor of activated T cells 1 (NFATc1) is mainly expressed in tumor microenvironment, especially in macrophages. However, whether NFATc1 is involved in the polarization of tumor associated macrophages (TAMs) and tumor progression in cervical cancer (CC) remains unclear. Immunofluorescence staining was used to detect the expression of CD68 and NFATc1 in CC tissues or adjacent normal tissues of patients. RT-qPCR, flow cytometry, ELISA, and inhibitors treatment were used to observe the effect of NFATc1 on TAMs polarization. Clonal formation, scratch, and transwell assays were used to examine the effects of NFATc1-transfected macrophages or NFATc1-transfected TAM on tumor proliferation, migration, and invasion. Further, a xenograft model was established to confirm the roles of NFATc1+ TAM in CC tumorigenesis. NFATc1+CD68+/CD68+ TAMs ratio was significantly increased in CC tissues compared with the normal tissue, and NFATc1+ TAM showed an M2-like TAM subtype. NFATc1 induced macrophages to secrete IL-10, which further induced M2 polarization of macrophages. Mechanically, the c-myc-PKM2 pathway mediated the expression of IL-10 in NFATc1-induced macrophages. Functionally, NFATc1 induced M2 macrophages promoted the proliferation, migration, and invasion of CC cells, and the knockout of NFATc1 in TAMs significantly inhibited the tumor-promoting function of TAMs. Further, the tumorigenesis test in nude mice confirmed that NFATc1+ TAM promoted the tumorigenicity of CC cells in vivo. In conclusion, NFATc1 mediated IL-10 secretion by regulating the c-myc/PKM2 pathway, thereby induce M2 polarization of TAMs and promote the progression of CC.

Abstract
Cervical carcinoma is one of the preventable malignancies in the United States. Age-appropriate screening has decreased the incidence of cervical cancer. A multitude of age-appropriate screening methods is available including Papanicolaou (Pap) smear cytology, human papillomavirus (HPV) DNA testing, and visual inspection tests. Patients who are not up to date with the screening can remain asymptomatic until the advanced stage like in the case of our patient. We present a 59-year-old female, who came in with progressively worsening shortness of breath on exertion, chest tightness, significant weight loss, and vaginal bleeding for the past six months. On investigations, she was found to have cannonball metastases in the lung. The patient remained critically ill during her course of hospital stay and eventually passed away.

LncRNA MAGI2-As3 Suppresses the Proliferation and Invasion of Cervical Cancer by Sponging MiR-15b. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:9707206. [PMID: 35126958 PMCID: PMC8808199 DOI: 10.1155/2022/9707206] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 01/06/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Cervical cancer is the leading cause of cancer deaths among women, and more than 85% of cervical cancer deaths occur in low and middle-income countries. The purpose of this study is to investigate the functions of MAGI2-AS3 and miR-15b in cervical cancer. MATERIALS AND METHODS The mRNA levels of MAGI2-AS3, miR-15b, and CCNE1 were evaluated using RT-qPCR assay. Dual-luciferase reporter gene assay was used to confirm whether miR-15b binds to CCNE1. RESULTS LncRNA MAGI2-AS3 was downregulated, while miR-15b was upregulated in cervical cancer. Cervical cancer patients with low expression of MAGI2-AS3 have a poor prognosis. Upregulation of MAGI2-AS3 inhibited proliferative and invasive abilities of HeLa cells via regulating the expression of miRNA-15b. MiR-15b inhibitor suppressed cell proliferation and invasion. CCNE1 was a direct target gene of miR-15b, which binds to the 3'-UTR of its mRNA. MiR-15b partially reversed the inhibitory effect of overexpression of MAGI2-AS3 on the proliferation and invasion of HeLa cells. MAGI2-AS3 mediated the expression of CCNE1 in HeLa cells. CONCLUSION LncRNA MAGI2-AS3 inhibits the proliferation and invasion of cervical cancer cells via the miRNA-15/CCNE1 axis. Our results illustrates that MAGI2-AS3 can be used as a useful clinical predictor for early diagnosis and prognosis assessment of cervical cancer.

Abstract
Angiopoietin-like 3 (ANGPTL3) has been uncovered to play an oncogenic role in several kinds of human malignancies. Nevertheless, whether ANGPTL3 functions in cervical cancer (CC) has not yet been reported. This paper is intended to explore the impact of ANGPTL3 on CC cells and elucidate the potential mechanism. In this study, quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were performed to analyze the ANGPTL3 expression. Western blot was also performed to examine integrin αvβ3 protein level. Cell proliferation was evaluated by MTT assay, EdU staining and Western blot analysis. In addition, the migratory and invasive abilities of cells were, respectively, estimated by wound healing and transwell assays. Tube formation assay was performed to determine endothelial cell angiogenesis. Levels of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor 2 (VEGFR2) were measured by ELISA. As a result, ANGPTL3 expression was significantly higher in CC cells relative to that in normal cervical cells. Silencing of ANGPTL3 suppressed cell proliferation, migration and invasion. Besides, downregulation of ANGPTL3 inhibited human umbilical vein endothelial cell (HUVEC) angiogenesis and repressed protein level of integrin alpha v beta 3 (αvβ3). Upregulation of αvβ3 offsets the inhibitory effect of ANGPTL3 on proliferation, migration and invasion in CC cells. Upregulated expression of αvβ3 promoted blood vessel formation and secretions of VEGF and VEGFR2. In conclusion, ANGPTL3 silencing may serve as a tumor suppressor in CC through integrin αvβ3, which provides a potentially novel therapeutic target for patients with CC.

Abstract
Background Cervical cancer (CC) is one of the most common malignancies affecting female worldwide. Long non-coding RNAs (lncRNAs) are increasingly indicated as crucial participants and promising therapeutic targets in human cancers. The main objective of this study was to explore the functions and mechanism of LINC00885 in CC. Methods RT-qPCR and western blot were used to detect RNA and protein levels. Functional and mechanism assays were respectively done for the analysis of cell behaviors and molecular interplays. Results Long intergenic non-coding RNA 885 (LINC00885) was discovered to be upregulated in CC tissues and cell lines through bioinformatics analysis and RT-qPCR. Overexpression of LINC00885 promoted proliferation and inhibited apoptosis, whereas its silence exerted opposite effects. The cytoplasmic localization of LINC00885 was ascertained and furthermore, LINC00885 competitively bound with miR-3150b-3p to upregulate BAZ2A expression in CC cells. Rescue assays confirmed that LINC00885 regulated CC proliferation and apoptosis through miR-3150b-3p/BAZ2A axis. Finally, we confirmed that LINC00885 aggravated tumor growth through animal experiments. Conclusions LINC00885 exerted oncogenic function in CC via regulating miR-3150b-3p/BAZ2A axis. These findings suggested LINC00885 might serve as a potential promising therapeutic target for CC patients.

Abstract
Cervical cancer is one of the most common malignant tumors among women in the world. In clinical practice, Hedyotis diffusa has pharmacological effects in treating cervical cancer, but its components are relatively complex, and the mechanism of Hedyotis diffusa in treating cervical cancer is still unclear. In this work, the potential active components and mechanism of Hedyotis diffusa in the treatment of cervical cancer were explored by means of network pharmacology. By constructing its active ingredient-target network, and enriching and analyzing the targets, we found the key targets and their effective components (beta-Sitosterol and Quercetin) that play a therapeutic role. Finally, we evaluated the prognostic value of the core target genes through survival analysis. Our work initially explored the therapeutic mechanism of cervical cancer, which lays a theoretical foundation for further exploring its pharmacological action and its clinical application.

Abstract
In India, cervical cancer is the second leading cause of cancer-related mortality among females. Around one-third are expected to develop recurrence or metastasis during follow-up. Liver metastasis is rarely requiring palliative treatment. Patient compliance to strict follow-up is vital to detect early metastasis to be able to improve survival. A 58-year-old lady (International Federation of Gynecology and Obstetrics [FIGO] stage IIIB) was treated with concurrent chemoradiotherapy. During follow-up, she had complained of abdominal pain for which cross-sectional imaging revealed a left lobe liver lesion fistulizing into the stomach. Liver metastasis fistulizing into the stomach is a rarity, and a biopsy is required to confirm metastasis or maybe a second primary. Although palliation in the form of chemotherapy is the standard, minor or major hepatectomy can be considered in patients with good performance status at high-volume centers. A tailored multidisciplinary team approach is required for better survival.

Abstract
The aim of this study is to fabricate nanophotosensitizers composed of methoxy poly(ethylene glycol) (mPEG), chlorin e6 (Ce6), and phenylboronic acid pinacol ester (PBAP) with diselenide linkages for reactive oxygen species (ROS)-sensitive photodynamic therapy (PDT) of cervical cancer cells. To fabricate nanophotosensitizers, Ce6 was conjugated with mPEG via selenocystamine linkage and then remaining carboxylic acid groups of Ce6 was attached to PBAP (mPEGseseCe6PBAP conjugates). Nanophotosensitizers of mPEGseseCe6PBAP conjugates were prepared by dialysis method. In transmission electron microscope (TEM) observation, nanophotosensitizers of mPEGseseCe6PBAP conjugates have spherical shapes and their diameters were less than 150 nm. The average diameter of mPEGseseCe6PBAP nanophotosensitizers was 92.7 ± 9.6 nm in particle size analysis. When H2O2 was added to the nanophotosensitizer solution, nanophotosensitizers were sensitively disintegrated according to the H2O2 concentration and then changed from monomodal distribution to multimodal distribution in particle size distribution. Furthermore, Ce6 release from nanophotosensitizers also increased according to the H2O2 concentration. When H2O2 was added to cell culture of HeLa human cervical cancer cells, intracellular Ce6 uptake of nanophotosensitizers were gradually increased according to the H2O2 concentration, indicating that nanophotosensitizers showed ROS-sensitive delivery of Ce6 against cancer cells.As well as free Ce6, nanophotosensitizers in the absence of light irradiation have low intrinsic cytotoxicity against RAW264.7 cells and HeLa cells. However, nanophotosensitizers induced cell death dose-dependently under light irradiation. Especially, nanophotosensitizers showed significantly higher ROS generation and phototoxicity against HeLa cells in vitro. When nanophotosensitizers were intravenously administered to animal tumor xenograft model of HeLa cells, tumor tissues revealed stronger fluorescence intensity than other tissues by light irradiation while absence of light irradiation induced relatively lower fluorescence intensity in tumor tissues, indicating that nanophotosensitizers have sensitivity against oxidative stress in tumor tissues. We suggest that nanophotosensitizers of mPEGseseCe6PBAP conjugates are promising vehicle for PDT of cervical cancer cells.

Abstract
Cervical cancer is the fourth most common cancer in women worldwide and is predominantly caused by infection with human papillomavirus (HPV). However, a small subset of cervical cancers tests negative for HPV, including true HPV-independent cancers and false-negative cases. True HPV-negative cancers appear to be more prevalent in certain pathological adenocarcinoma subtypes, such as gastric- and clear-cell-type adenocarcinomas. Moreover, HPV-negative cervical cancers have proven to be a biologically distinct tumor subset that follows a different pathogenetic pathway to HPV-associated cervical cancers. HPV-negative cervical cancers are often diagnosed at an advanced stage with a poor prognosis and are expected to persist in the post-HPV vaccination era; therefore, it is important to understand HPV-negative cancers. In this review, we provide a concise overview of the molecular pathology of HPV-negative cervical cancers, with a focus on their definitions, the potential causes of false-negative HPV tests, and the histology, genetic profiles, and pathogenesis of HPV-negative cancers.

Abstract
BACKGROUND It has been demonstrated by studies globally that RNA binding proteins (RBPs) took part in the development of cervical cancer (CC). Few studies concentrated on the correlation between RBPs and overall survival of CC patients. We retrieved significant DEGs (differently expressed genes, RNA binding proteins) correlated to the process of cervical cancer development. METHODS Expressions level of genes in cervical cancer and normal tissue samples were obtained from GTEx and TCGA database. Differently expressed RNA binding proteins (DEGs) were retrieved by Wilcoxon sum-rank test. ClusterProfiler package worked in R software was used to perform GO and KEGG enrichment analyses. Univariate proportional hazard cox regression and multivariate proportional hazard cox regressions were applied to identify DEGs equipped with prognostic value and other clinical independent risk factors. ROC curve was drawn for comparing the survival predict feasibility of risk score with other risk factors in CC patients. Nomogram was drawn to exhibit the prediction model and validated by C-index and calibration curve. Correlations between differentially expressed RNA binding proteins (DEGs) and other clinical features were investigated by t test or Cruskal Wallis analysis. Correlation between Immune and DEGs in cervical cancer was investigated by ssGSEA. RESULTS 347 differentially expressed RBPs (DEGs) were retrieved from cervical cancer tissue and normal tissue samples. GO enrichment analysis showed that these DEGs involved in RNA splicing, catabolic process and metabolism. Cox regression model showed that there were ten DEGs significantly associated with overall survival of cervical cancer patients. WDR43 (HR = 0.423, P = 0.008), RBM38 (HR = 0.533, P < 0.001), RNASEH2A (HR = 0.474, P = 0.002) and HENMT1 (HR = 0.720, P = 0.071) played protective roles in survival among these ten genes. Stage (Stage IV vs Stage I HR = 3.434, P < 0.001) and risk score (HR = 1.214, P < 0.001) were sorted as independent prognostic risk factors based on multivariate cox regression. ROC curve validated that risk score was preferable to predict survival of CC patients than other risk factors. Additionally, we found some of these ten predictor DEGs were correlated significantly in statistic with tumor grade or stage, clinical T stage, clinical N stage, pathology or risk score (all P < 0.05). Part of immune cells and immune functions showed a lower activity in high risk group than low risk group which is stratified by median risk score. CONCLUSION Our discovery showed that many RNA binding proteins involved in the progress of cervical cancer, which could probably serve as prognostic biomarkers and accelerate the discovery of treatment targets for CC patients.

Abstract
Objective Pulmonary metastasis (PM) is an independent risk factor affecting the prognosis of cervical patients, but it still lacks a prediction. This study aimed to develop machine learning-based predictive models for PM. Methods A total of 22,766 patients diagnosed with or without PM from the Surveillance, Epidemiology, and End Results (SEER) database were enrolled in this study. The cohort was randomly split into a train set (70%) and a validation set (30%). In addition, 884 Chinese patients from two tertiary medical centers were included as an external validation set. Duplicated and useless candidate variables were excluded, and sixteen variables were included for the machine learning algorithm. We developed five predictive models, including the generalized linear model (GLM), random forest model (RFM), naive Bayesian model (NBM), artificial neural networks model (ANNM), and decision tree model (DTM). The predictive performance of these models was evaluated by the receiver operating characteristic (ROC) curve and calibration curve. The Cox proportional hazard model (CPHM) and competing risk model (CRM) were also included for survival outcome prediction. Results Of the patients included in the analysis, 2456 (4.38%) patients were diagnosed with PM. Age, organ-site metastasis (liver, bone, brain), distant lymph metastasis, tumor size, and pathology were the important predictors of PM. The RFM with 9 variables introduced was identified as the best predictive model for PM (AUC = 0.972, 95% CI: 0.958-0.986). The C-index for the CPHM and CRM was 0.626 (95% CI: 0.604-0.648) and 0.611 (95% CI: 0.586-0.636), respectively. Conclusion The prediction algorithm derived by machine-learning-based methods shows a robust ability to predict PM. This result suggests that machine learning techniques have the potential to improve the development and validation of predictive modeling in cervical patients with PM.

Dose Prediction Models Based on Geometric and Plan Optimization Parameter for Adjuvant Radiotherapy Planning Design in Cervical Cancer Radiotherapy. JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:7026098.

Abstract
The prediction of an additional space for the dose sparing of organs at risk (OAR) in radiotherapy is still difficult. In this pursuit, the present study was envisaged to find out the factors affecting the bladder and rectum dosimetry of cervical cancer. Additionally, the relationship between the dose-volume histogram (DVH) parameters and the geometry and plan dose-volume optimization parameters of the bladder/rectum was established to develop the dose prediction models and guide the planning design for lower OARs dose coverage directly. Thirty volume modulated radiation therapy (VMAT) plans from cervical cancer patients were randomly chosen to build the dose prediction models. The target dose coverage was evaluated. Dose prediction models were established by univariate and multiple linear regression among the dosimetric parameters of the bladder/rectum, the geometry parameters (planning target volume (PTV), volume of bladder/rectum, overlap volume of bladder/rectum (OV), and overlapped volume as a percentage of bladder/rectum volume (OP)), and corresponding plan dose-volume optimization parameters of the nonoverlapping structures (the structure of bladder/rectum outside the PTV (NOS)). Finally, the accuracy of the prediction models was evaluated by tracking d = (predicted dose-actual dose)/actual in additional ten VMAT plans. V 30, V 35, and V 40 of the bladder and rectum were found to be multiple linearly correlated with the relevant OP and corresponding dose-volume optimization parameters of NOS (regression R 2 > 0.99, P < 0.001). The variations of these models were less than 0.5% for bladder and rectum. Percentage of bladder and rectum within the PTV and the dose-volume optimization parameters of NOS could be used to predict the dose quantitatively. The parameters of NOS as a limited condition could be used in the plan optimization instead of limiting the dose and volume of the entire OAR traditionally, which made the plan optimization more unified and convenient and strengthened the plan quality and consistency.

Bioorg Chem 2021; 120:105488.

Abstract
Cervical cancer is a most prevalent gynecological malignancy around the world. Long non-coding RNAs (lncRNAs) are recognized as crucial players in the cellular activities of diverse cancers including cervical cancer. We aimed to reveal the biological function of lncRNA small nucleolar RNA host gene 6 (SNHG6) in cervical cancer. Our findings illuminated that SNHG6 expression was elevated in cervical cancer tissues and cell lines, and highly expressed SNHG6 was associated with poor outcome in patients with cervical cancer. Moreover, knockdown of SNHG6 repressed cervical cancer development via inhibiting cell proliferation and migration and accelerating cell apoptosis. Further, SNHG6 was a sponge of miR-485-3p and uridine-cytidine kinase 2 (UCK2) was the functional target of miR-485-3p. SNHG6 increased UCK2 expression by binding with miR-485-3p in cervical cancer cells. The rescue experiments showed that SNHG6 contributed to malignant phenotypes of cervical cancer cells by the miR-485-3p/UCK2 axis. Additionally, SNHG6 activated the Wnt/β-catenin pathway to enhance the proliferative and migratory ability of cervical cancer cells. Overall, this work revealed that SNHG6 promoted malignant behaviors of cervical cancer cells by binding with miR-485-3p to regulate UCK2 and activating the Wnt/β-catenin pathway, which may offer a beneficial direction to treat cervical cancer.

Abstract
Cervical cancer is a major human papillomavirus-related disease and is the fourth leading cause of death by cancer among women. Plants are an important source of anticancer compounds and many of them are currently used in the treatment of cancer. Several reports suggest the efficacy of plant-derived compounds increases when used in combination. This study was carried out to evaluate the effect of four plant-derived compounds such as curcumin (C), ellagic acid (E), quercetin (Q), and resveratrol (R) when used alone or in combinations using HeLa cervical cancer cells. All four phytocompounds showed effective cytotoxic activities in targeting HeLa cervical cancer cells as determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium assay. The selected phytocompound combinations C + E, C + Q, and Q + R work synergistically while the combination C + R shows additive effects. All four phytocompounds reduce cell migration as determined by in vitro wound-healing assay. The expression level of the epidermal growth factor receptor is significantly downregulated both in individual and combination. The flow cytometry analysis of cell cycle indicates that individual drugs curcumin, ellagic acid, quercetin, and resveratrol, each with 20 µM effectively arrested cell cycle at the S-phase while the combination of drugs (10 + 10 µM) at the G2/M phase.

Abstract
PURPOSE Almost all cervical cancers are caused by human papillomavirus (HPV) and patients with advanced stage are at high risk for relapse. Circulating HPV DNA (HPV ctDNA) may serve as a residual tumor marker at the end of chemoradiation or to predict relapse during the follow-up period. EXPERIMENTAL DESIGN We analyzed serum samples from 94 HPV16- or HPV18-related CCs from the BioRAIDs prospective cohort. Samples were collected before and after treatment and during an 18-month follow-up period. Using digital droplet PCR (ddPCR), we assessed the relevance of circulating HPV E7 gene as a marker for residual disease compared to HPV integration site and PIK3CA mutations. Finally, the prognostic impact of circulating HPV E7 gene was assessed with its prediction value of relapse. RESULTS HPV E7 gene was the most sensitive tumor marker, superior to both HPV integration sites and PIK3CA mutations in serum. Circulating HPV DNA (HPV ctDNA) was detected in 63% (59/94) of patients, before treatment. HPV ctDNA detection in serum sample was associated with high FIGO stage (P = 0.02) and para-aortic lymph node involvement (P = 0.01). The level of HPV ctDNA was positively correlated with HPV copy number in the tumor (R = 0.39, P < 0.001). Complete clearance of HPV ctDNA by the end of treatment was significantly associated with a longer PFS (P < 0.0001). Patients with persistent HPV ctDNA in serum relapsed with a median time of 10 months (range, 2-15) from HPV ctDNA detection. CONCLUSIONS HPV ctDNA detection is a useful marker to predict relapse in cervical cancer.See related commentary by Wentzensen and Clarke, p. 5733.

Abstract
Objective To analyse the positive rates of low-grade (LSIL) and high-grade (HSIL) squamous intraepithelial lesions, and cervical cancer (CC), and identify groups at high risk for CC in Guangxi. Setting CC screening options in Guangxi, which is the only minority autonomous area in South China, include the National Cervical Cancer Screening Project (NCCSP) and physical examination (PE). Methods This study was based on PE and NCCSP sample data obtained from 2012 to 2019. We calculated the positive rates of LSIL, HSIL, and CC; analysed the adjusted odds ratio (aOR) and 95% confidence intervals (CI) of the variables in multivariate logistic regression; and subsequently identified groups at high risk for CC. Results The positive rates of LSIL, HSIL, and CC for the total of 873,880 samples were 1.89%, 0.60%, and 0.03%, respectively. Females over 64 years of age (vs. 50–64; aOR = 2.05; 95% CI, 1.71–2.46; P < 0.001) and those from urban (vs. rural; aOR = 1.66; 95% CI, 1.57–1.76; P < 0.001), minority (vs. non-minority; aOR = 1.24; 95% CI, 1.13–1.35; P < 0.001), and coastal (vs. inland; aOR = 1.15; 95% CI, 1.06–1.25; P = 0.001) areas were associated with a high risk of HSIL. Females over 64 (vs. 50–64; aOR = 4.37; 95% CI, 2.88–6.63; P < 0.001) and those from urban (vs. rural; aOR = 3.05; 95% CI, 2.36–3.95; P < 0.001) areas were significantly associated with a high risk of CC. Conclusion Females from urban areas in Guangxi are at high risk for CC. Public health strategies should focus on high-risk populations.

Abstract
Background: Population-based data on the risk assessment of newly diagnosed cervical cancer patients' bone metastasis (CCBM) are lacking. This study aimed to develop various predictive models to assess the risk of bone metastasis via machine learning algorithms. Materials and Methods: We retrospectively reviewed the CCBM patients from the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute to risk factors of the presence of bone metastasis. Clinical usefulness was assessed by Akaike information criteria (AIC) and multiple machine learning algorithms based predictive models. Concordance index (C-index) and receiver operating characteristic (ROC) curve were used to define the predictive and discriminatory capacity of predictive models. Results: A total of 16 candidate variables were included to develop predictive models for bone metastasis by machine learning. The areas under the ROC curve (AUCs) of the random forest model (RF), generalized linear model (GL), support vector machine (SVM), eXtreme Gradient Boosting (XGBoost), artificial neutral network (ANN), decision tree (DT), and naive bayesian model (NBM) ranged from 0.85 to 0.93. The RF model with 10 variables was developed as the optimal predictive model. The weight of variables indicated the top seven factors were organ-site metastasis (liver, brain, and lung), TNM stage and age. Conclusions: Multiple machine learning based predictive models were developed to identify risk of bone metastasis in cervical cancer patients. By incorporating clinical characteristics and other candidate variables showed robust risk stratification for CCBM patients, and the RF predictive model performed best among these predictive models.

Abstract
Objective To study the effects of psychological care combined with traditional Chinese medicine treatment on the postoperative psychological stress response and the expression levels of serum C-reactive protein (CRP) and interferon-γ (IFN-γ) in patients with advanced cervical cancer. Method 232 postoperative advanced cervical cancer patients treated in our hospital from December 2015 to December 2018 were selected as study objects and divided into the control group and study group using the random number table method. The control group was given basic care combined with traditional Chinese medicine treatment, while the study group was given psychological care treatment on the basis of the control group to compare the treatment effect, psychological stress response, pain level, quality of life, and long-term efficacy of the two groups. The serum CRP and IFN-γ levels and their correlation with different psychological stress responses were compared between the two groups before and after treatment. Result Comparing the clinical efficacy of the two groups, the total effective rate of the study group was higher than that of the control group. VAS scores in the study group were significantly lower than those in the control group 30 and 60 days after treatment. The SCL-90 scores of the study group after treatment were lower than those of the control group. After treatment, the differences between the two groups were statistically significant in the scores of emotional function, social function, and role function. The two-year cumulative survival rate in the study group (82.76%) was significantly increased compared to that in the control group (55.17%). The serum CRP and IFN-γ expression levels in the two groups were significantly decreased after treatment compared to those before treatment, and the serum CRP and IFN-γ expression levels in the study group were significantly decreased compared to those in the control group. Conclusion Psychological care combined with traditional Chinese medicine in the treatment of advanced cervical cancer patients after surgery was effective in improving patients' psychological status, reducing their pain level, relieving postoperative negative emotions, increasing compliance, improving the quality of life, helping to prolong survival time, and controlling serum indexes back to normal, which was worth promoting in clinical practice.

Abstract
Objective This study was aimed to investigate the clinical effect of Chinese herbal decoction combined with basic chemoradiotherapy and nursing intervention in the treatment of cervical cancer and the effect on serum carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), and tumor necrosis factor-α (TNF-α) levels. Methods A total of 200 cervical cancer patients in our hospital from June 2015 to November 2018 were selected and randomly divided into a study group and a control group. The control group was given chemoradiotherapy and psychological nursing treatment, and the study group was given self-made Chinese herbal decoction on the basis of the control group. The clinical efficacy and serum CEA, CA125, and TNF-α levels were assessed. Results After treatment, the total effective rate of the study group was significantly higher than that of the control group. The levels of serum CEA, CA125, and TNF-α were decreased in the two groups after treatment, and the decrease in the study group was more significant than that in the control group. After treatment, CD3+ and CD4+ levels were increased compared with those before treatment, and the increase in the study group was also more obvious than that of the control group. The level of CD8+ was decreased compared with before treatment, and the decrease in the study group was more notable than that of the control group. The two-year cumulative survival rate of the study group was markedly higher than that of the control group. The quality-of-life of patients treated for 3 months, 1 year, and 2 years was dramatically improved compared to before treatment. The incidence of adverse reactions in the study group was lower than that of the control group. Conclusion The treatment of basic chemoradiotherapy and psychological nursing intervention combined with Chinese herbal decoction on cervical cancer patients can improve the clinical treatment effects, improve the patient's body immunity, reduce serum CEA, CA125, and TNF-α levels, prolong survival time, improve life quality, and reduce the incidence of adverse reactions, and it is worthy of clinical promotion.

Abstract
Cervical cancer (CC) is the third most common cancer among women and has a high mortality rate at the advanced stage. The mechanisms underlying the development and progression of CC are still elusive. Circular RNAs (circRNAs) play an important role in various physiological and pathological processes. The aim of this study was to identify the circRNAs significantly associated with cervical squamous cell carcinoma (CSCC), in order to discover novel diagnostic markers and elucidate their mechanistic basis.The circRNA expression profiles of CSCC and paired para-cancerous cervical tissues was downloaded from the Gene Expression Omnibus. Bioinformatics analysis were used to screen for the differentially expressed circRNAs (DECRs). The expression levels of hsa_circ_0000745, hsa_circ_0084927, hsa_circ_0002762, hsa_circ_0075341, hsa_circ_0007905, hsa_circ_0031027, hsa_circ_0065898, hsa_circ_0070190, and hsa_circ_0078383 were verified in CC and normal cervical tissues by quantitative real-time PCR.A total of 197 DECRs were identified between the CSCC and normal tissues, including 87 upregulated and 110 downregulated circRNAs. In addition, 37 miRNAs were predicted for the upregulated circRNAs and 39 for the downregulated circRNAs. Functional analysis showed that the DECRs were associated with positive regulation of substrate adhesion-dependent cell spreading, metabolism, positive regulation of GTPase activity, protein regulation, and intercellular adhesion. The MAPK signaling pathway that plays a significant role in the progression of CC, was also enriched. Consistent with the in-silico analysis, hsa_circ_0000745, hsa_circ_0084927, hsa_circ_0002762, hsa_circ_0007905 were upregulated and hsa_circ_0078383 was downregulated in CC tissues (P < .001), whereas hsa_circ_0075341 (P < .001) and hsa_circ_0031027 (P = .001) showed opposite trends.We identified novel diagnostic and therapeutic biomarkers of CSCC along with the mechanistic basis.

Abstract
Purpose The route of administration of a therapeutic tumor vaccine is a critical factor in inducing antitumor activity. In this study, we explored the effects of three vaccination routes (subcutaneous, peritumoral, and intratumoral injection) on antitumor activity induced by a human papillomavirus (HPV) therapeutic vaccine containing HPV16 E7 peptide combined with the adjuvant CpG ODN in established TC-1 grafted tumors. Methods We used flow cytometry to evaluate splenic and tumor-infiltrating immune cells. We also assessed transcriptional changes in a sequence of immune-related genes in tumors of different treatment groups using quantitative real-time polymerase chain reaction. Immunohistochemistry was used to determine the expression of molecules related to tumor infiltrating immune cells, angiogenesis, and cancer-associated fibroblasts in tumor tissues. Results Our results suggested that intratumoral and peritumoral vaccination generated enhanced antitumor activity compared to subcutaneous delivery. In particular, intratumoral vaccination elicited a stronger antitumor effect, with two of the six treated mice being nearly tumor-free at day 28. Three vaccination routes induced increases in splenic CD4+ and/or CD8+ T lymphocytes, and marked decreases in immunosuppressive cells. Peritumoral vaccination increased the tumor-infiltrating CD8+T cells in tumors, while intratumoral vaccination enhanced the tumor-infiltrating CD4+ and CD8+ T lymphocytes, as well as decreased the tumor-infiltrating of immunosuppressive cells, which may result in stronger inhibition of tumor growth and prolonged survival in mice bearing tumors. Furthermore, compared to the subcutaneous route, intratumoral vaccination led to a significant increase in antitumor cytokines and chemokines. In addition, our data showed marked downregulation of MMP-2, MMP-9, VEGF, CD31, and α-SMA in the intratumoral vaccination group, which might contribute to the suppression of tumor invasion, angiogenesis, and metastasis. Conclusion Overall, intratumoral vaccination is superior to subcutaneous delivery and has the potential to inhibit tumor growth by improving the tumor microenvironment.

Abstract
Cervical cancer is one of the most common malignant tumors in women, and its morbidity and mortality are increasing year by year worldwide. Therefore, an urgent and challenging task is to identify potential biomarkers for cervical cancer. This study aims to identify the hub genes based on the GEO database and then validate their prognostic values in cervical cancer by multiple databases. By analysis, we obtained 83 co-expressed differential genes from the GEO database (GSE63514, GSE67522 and GSE39001). GO and KEGG enrichment analysis showed that these 83 co-expressed it mainly involved differential genes in DNA replication, cell division, cell cycle, etc.. The PPI network was constructed and top 10 genes with protein-protein interaction were selected. Then, we validated ten genes using some databases such as TCGA, GTEx and oncomine. Survival analysis demonstrated significant differences in CDC45, RFC4, TOP2A. Differential expression analysis showed that these genes were highly expressed in cervical cancer tissues. Furthermore, univariate and multivariate cox regression analysis indicated that CDC45 and clinical stage IV were independent prognostic factors for cervical cancer. In addition, the HPA database validated the protein expression level of CDC45 in cervical cancer. Further studies investigated the relationship between CDC45 and tumor-infiltrating immune cells via CIBERSORT. Finally, gene set enrichment analysis (GSEA) showed CDC45 related genes were mainly enriched in cell cycle, chromosome, catalytic activity acting on DNA, etc. These results suggested CDC45 may be a potential biomarker associated with the prognosis of cervical cancer.

Abstract
QKI is a vital regulator in RNA splicing and maturation, but its role in cervical cancer (CC) is little known. In this study, we found that QKI is decreased in human CC, and overexpression of QKI inhibits HeLa cell proliferation and promotes the apoptosis of cancer cells. We identified hundreds of endogenous QKI-regulated alternative splicing events (ASEs) and differentially expressed genes (DEGs) in QKI-overexpressed HeLa cells by RNA-seq and selectively validated their expression by quantitative reverse-transcription polymerase chain reaction. The gene ontology and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis showed that QKI-regulated ASEs and DEGs were closely related to cancer, apoptosis, and transcriptional regulatory functions. In short, QKI may affect the occurrence and development of CC by regulating gene expression through AS.

Abstract
Cervical cancer is a malignant tumor of the female reproductive system. At present, its occurrence, development and transfer mechanism are not entirely clear. APMAP (Adipocyte Plasma Membrane Associated Protein) is a glycosyl type II transmembrane protein that is mainly distributed in the plasma membrane and endoplasmic reticulum of adipocytes. APMAP has been reported to be involved in lipid transport and can induce epithelial-mesenchymal transition of prostate cancer and the liver metastasis of colorectal cancer. However, the role of APMAP in cervical cancer is still unknown. We analyzed the expression and prognosis of APMAP using data in both the GEO and the TCGA databases. We analyzed the function of APMAP using Transwell, wound healing assay and flow cytometry, and assessed the main mechanisms of APMAP by RT-PCR and Western blotting. We found that APMAP was highly expressed in cervical cancer tissues, and patients with high expression had poor prognosis. The functional in vitro experiments demonstrated that APMAP knockdown significantly inhibited the migration ability of cervical cancer cells, but had little effect on cell apoptosis. Mechanically, APMAP promotes cervical cancer cell migration and epithelial-mesenchymal transition by activating the Wnt/β-catenin pathway. Overall, APMAP is a potential prognostic marker as well as a therapeutic target of cervical cancer.

Abstract
Although lymphatic endothelial cells (LECs) serve a positive role in tumor lymphatic metastasis, the regulation of LECs undergoing migration similar to that of tumor cells remains poorly understood. A previous study revealed that semaphorin 4C (Sema4C) could be a marker of LECs in cervical cancer. Thus, the present study aimed to understand the mechanism via which Sema4C could promote the development of tumor-associated characteristics in LECs in cervical cancer. Primary tumor-associated LECs (TLECs) were distinguished from cervical cancer by flow cytometry. The promigratory ability was assessed using the Transwell assay. Lentivirus infection was used to alter the expression of Sema4C in TLECs. Confocal laser scanning was used to determine the infection efficiency of lentivirus infection. Sema4C/ERK/E-cadherin pathway was measured by reverse transcription-quantitative PCR and western blotting. The co-localization of Sema4C and the lymphatic marker lymphatic vessel endothelial hyaluronan receptor 1 was verified. Primary tumor-associated LECs (TLECs) were isolated from a mouse xenograft cervical tumor model. It was revealed that overexpressing Sema4C stimulated the migratory ability of TLECs, downregulated E-cadherin expression and stimulated ERK phosphorylation, whereas knocking down Sema4C had the opposite effects. The treatment of PD98059 (ERK inhibitor) blocked the pro-migratory ability of TLECs, which indicated a dependence on the ERK signaling pathway. It was identified that the Sema4C/ERK/E-cadherin pathway may be critical for the migration of TLECs, which may promote lymph node metastasis. Therefore, Sema4C could be a promising target for the treatment of cervical cancer with lymphatic metastasis.

Abstract
Cervical cancer (CC) is a type of gynecological malignancy that poses a significant threat to females. The aim of the present study was to examine the role of long intergenic non-protein coding RNA 1123 (LINC01123) and its underlying molecular mechanism in the development of CC. mRNA expression levels of LINC01123 and microRNA (miR)-361-3p in CC tissue samples and cell lines were evaluated using reverse transcription-quantitative PCR. Cell viability, migration and invasion were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, wound healing and Transwell assays. Moreover, a xenograft tumor model was established for elucidating the influence of LINC01123 knockdown on tumor growth in vivo. A dual-luciferase reporter assay was used to confirm the association between LINC01123 and miR-361-3p, and miR-361-3p and tetraspanin 1 (TSPAN1). Western blot analysis was used to determine TSPAN1 protein expression. LINC01123 expression was upregulated and miR-361-3p expression was reduced in CC tissue samples and cell lines. Knockdown of LINC01123 inhibited cell viability, migration and invasion in vitro, and suppressed tumor growth in vivo. Furthermore, LINC01123 targeted miR-361-3p and negatively regulated miR-361-3p expression. Overexpression of miR-361-3p inhibited cell viability, migration and invasion in HeLa and CaSki cells. Additionally, miR-361-3p targeted TSPAN1 and negatively regulated TSPAN1 expression. Inhibition of miR-361-3p and overexpression of TSPAN1 reversed the effect of LINC01123 knockdown on cell proliferation, migration and invasion in HeLa cells. Knockdown of LINC01123 inhibited cell proliferation, migration and invasion via miR-361-3p/TSPAN1 regulation in CC, which may present an effective target for treatment of CC.

Abstract
Cervical cancer is one of the leading causes of cancer-associated mortality in gynecological diseases and ranks third among female cancers worldwide. Although early detection and vaccination have reduced incidence rates, cancer recurrence and metastasis lead to high mortality due to the lack of effective medicines. The present study aimed to identify novel drug candidates to treat cervical cancer. In the present study, lanatoside C, an FDA-approved cardiac glycoside used for the treatment of heart failure, was demonstrated to have anti-proliferative and cytotoxic effects on cervical cancer cells, with abrogation of cell migration in a dose-dependent manner. Lanatoside C also triggered cell apoptosis by enhancing reactive oxygen species production and reducing the mitochondrial membrane potential, which induced cell cycle arrest at the S and G2/M phases. Furthermore, lanatoside C inhibited the phosphorylation of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 6 (STAT6), while inducing the expression of suppressor of cytokine signaling 2, a negative regulator of JAK2-STAT6 signaling. Taken together, the results of the present study suggest that lanatoside C suppresses cell proliferation and induces cell apoptosis by inhibiting JAK2-STAT6 signaling, indicating that lanatoside C is a promising agent for the treatment of cervical cancer.

Abstract
Cervical cancer is one of the common malignancies in women, which is characterized with high invasion and metastatic tendency in its advanced stage. Increasing evidence indicates that methyltransferase-like (METTL) gene family is involved in the progression of various cancers. However, the functional role of methyltransferase-like gene family in cervical cancer remains unclear. In the present study, we found that METTL11A, a member of the methyltransferase-like gene family, was significantly over-expressed in cervical carcinoma by analyzing TCGA database. This finding was further validated in clinical tissue samples. Moreover, ectopic expression of METTL11A in cervical cancer cell lines promoted cell proliferation and migration both in vitro and in vivo. Differential gene expression analysis in the transcriptomic sequencing data indicated that ELK3 was down-regulated in METTL11A-silenced cervical cancer cells, which was further verified at both protein and mRNA levels. Functional experiments identified that METTL11A promoted migration of cervical cancer cells in an ELK3-dependent manner. This study will promote understanding the mechanism of cervical cancer progression and the functional role of methyltransferase-like gene families in cancers.

Abstract
The aim of this study was to fabricate a reactive oxygen species (ROS)-sensitive and folate-receptor-targeted nanophotosensitizer for the efficient photodynamic therapy (PDT) of cervical carcinoma cells. Chlorin e6 (Ce6) as a model photosensitizer was conjugated with succinyl β-cyclodextrin via selenocystamine linkages. Folic acid (FA)-poly(ethylene glycol) (PEG) (FA-PEG) conjugates were attached to these conjugates and then FA-PEG-succinyl β-cyclodextrin-selenocystamine-Ce6 (FAPEGbCDseseCe6) conjugates were synthesized. Nanophotosensitizers of FaPEGbCDseseCe6 conjugates were fabricated using dialysis membrane. Nanophotosensitizers showed spherical shapes with small particle sizes. They were disintegrated in the presence of hydrogen peroxide (H2O2) and particle size distribution changed from monomodal distribution pattern to multimodal pattern. The fluorescence intensity and Ce6 release rate also increased due to the increase in H2O2 concentration, indicating that the nanophotosensitizers displayed ROS sensitivity. The Ce6 uptake ratio, ROS generation and cell cytotoxicity of the nanophotosensitizers were significantly higher than those of the Ce6 itself against HeLa cells in vitro. Furthermore, the nanophotosensitizers showed folate-receptor-specific delivery capacity and phototoxicity. The intracellular delivery of nanophotosensitizers was inhibited by folate receptor blocking, indicating that they have folate-receptor specificity in vitro and in vivo. Nanophotosensitizers showed higher efficiency in inhibition of tumor growth of HeLa cells in vivo compared to Ce6 alone. These results show that nanophotosensitizers of FaPEGbCDseseCe6 conjugates are promising candidates as PDT of cervical cancer.

To achieve this study's goals, we selected 48 cervical carcinoma patients between January 2014 to January 2016 and subjected them to the miR-455-5p test by nano-PCR. The collected samples were then divided into two groups based on miR-455-5p levels. We had four HeLa cell groups, one group as the control, and one group overexpressed the miR-455-5p protein. A third group was miR-455-5p silent, and a separate group overexpressed both the miR-455-5p and S1PR1 proteins. Results also proved that the nano-PCR had a higher sensitivity than RT-PCR, and patients with poor prognosis had lesser miR-455-5p levels. Similarly, high levels of miR-455-5 contributed to cancer cell apoptosis and migration inhibition by targeting S1PR1 expression negatively. These two biomarkers are therefore significantly related to the prognosis of cervical carcinoma patients.

[PMID: 33416981 DOI: 10.1007/s00394-020-02440-9] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 11/04/2020] [Indexed: 12/13/2022]
Abstract
PURPOSE 6-Shogaol, an active phenolic compound from ginger (Zingiber officinale), can inhibit the growth of a variety of human cancer cells. Nevertheless, its underlying molecular mechanisms in cervical cancer remain unclear. In this study, we systematically examine the inhibitory effect of 6-shogaol on cervical cancer in vitro and in vivo. METHODS Cell proliferation was assessed by CCK8 assay and colony formation assay in HeLa and SiHa cells. We analyzed cell cycle and apoptosis through flow cytometry. GFP-LC3 puncta and transmission electron microscopy were used to observe autophagic bodies. Wound-healing assay and transwell assay were used for evaluating the migration of cells. Western blot was applied to detect protein expression levels. RESULTS 6-Shogaol could suppress cell proliferation and migration, cause cell cycle arrest in the G2/M phase in HeLa and SiHa cells. Moreover, 6-shogaol triggered the apoptosis process through the mitochondrial pathway by downregulating the expression levels of p-PI3K, p-Akt and p-mTOR. Further research indicated that the induction of apoptosis by 6-shogaol was remarkably decreased after the treatment of ROS scavenger and PI3K agonist. Additionally, 6-shogaol increased the number of LC3-positive puncta and autophagic bodies per cell in both HeLa and SiHa cells. Pretreatment of cells with Bafilomycin A1, an autophagy inhibitor, accelerated 6-shogaol mediated cell apoptosis, suggesting that induction of autophagy by 6-shogaol is suppressive to apoptosis. Furthermore, in vivo data revealed that 6-shogaol significantly inhibited tumor growth and cell proliferation in tumor tissues. CONCLUSION These findings suggested that 6-shogaol could be developed as a functional food ingredient, which is potentially used as therapeutic agents for patients with cervical cancer.

Vorinostat targets UBE2C to reverse epithelial-mesenchymal transition and control cervical cancer growth through the ubiquitination pathway. Eur J Pharmacol 2021; 908:174399. [PMID: 34331954 DOI: 10.1016/j.ejphar.2021.174399] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 07/19/2021] [Accepted: 07/28/2021] [Indexed: 01/16/2023]
Abstract
Vorinostat is a histone deacetylase inhibitor (HDACi) that was demonstrated in our previous study to inhibit the proliferation, migration, and invasion of cervical cancer cells by regulating the PI3K/Akt signaling pathway. However, the molecular mechanism of vorinostat in cervical cancer treatment remains to be further elucidated. A nude mouse xenograft model was established to analyze the antitumor effect of vorinostat in vivo. The combination of iTRAQ-based proteomics and parallel reaction monitoring (PRM) technology has proven to be an efficient and reliable method to identify potential targets for cancer chemotherapy. In this study, 254 differentially expressed proteins in vorinostat-treated cervical cancer cells, among which 180 were upregulated and 74 were downregulated, were identified by using an iTRAQ-based proteomic strategy. Subsequent bioinformatic and PRM analysis of these differentially expressed proteins indicated that UBE2C is a promising target of vorinostat in the inhibition of cervical cancer cell proliferation. We confirmed that the expression of endogenous UBE2C in cervical cancer cell lines was significantly higher than that in normal cervical epithelial cell lines. Additionally, we found that vorinostat downregulated the expression of UBE2C, SQSTM1/p62, N-cadherin, vimentin and upregulated E-cadherin in SiHa and HeLa cells. Our results also showed that vorinostat can downregulate the expression of SQSTM1/p62, N-cadherin, and vimentin during the treatment of cervical cancer cells by regulating UBE2C, while upregulating the expression of E-cadherin. In conclusion, vorinostat reverses epithelial-mesenchymal transition by targeting UBE2C and controls the proliferation of cervical cancer cells through the ubiquitination pathway. UBE2C can be used as a promising target for the development of vorinostat treatment strategies.

Abstract
Gynecologic cancers, starting in the reproductive organs of females, include cancer of cervix, endometrium, ovary commonly and vagina and vulva rarely. The changes in the composition of microbiome in gut and vagina affect immune and metabolic signaling of the host cells resulting in chronic inflammation, angiogenesis, cellular proliferation, genome instability, epithelial barrier breach and metabolic dysregulation that may lead to the onset or aggravated progression of gynecologic cancers. While microbiome in gynecologic cancers is just at horizon, certain significant microbiome signature associations have been found. Cervical cancer is accompanied with high loads of human papillomavirus, Fusobacteria and Sneathia species; endometrial cancer is reported to have presence of Atopobium vaginae and Porphyromonas species and significantly elevated levels of Proteobacteria and Firmicutes phylum bacteria, with Chlamydia trachomatis, Lactobacillus and Mycobacterium reported in ovarian cancer. Balancing microbiome composition in gynecologic cancers has the potential to be used as a therapeutic target. For example, the Lactobacillus species may play an important role in blocking adhesions of incursive pathogens to vaginal epithelium by lowering the pH, producing bacteriocins and employing competitive exclusions. The optimum or personalized balance of the microbiota can be maintained using pre- and probiotics, and fecal microbiota transplantations loaded with specific bacteria. Current evidence strongly suggest that a healthy microbiome can train and trigger the body's immune response to attack various gynecologic cancers. Furthermore, microbiome modulations can potentially contribute to improvements in immuno-oncology therapies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Imperata cylindrica (L.) Raeusch (Gramineae) is a medicinal spice traditionally used in the treatment of hypertension and cancer. AIM OF THE STUDY To assess the anti-metastatic potential of the methanol extract of I. cylindrica roots and determined its mechanisms of action. MATERIAL AND METHODS The growth inhibition activity of I. cylindrica root extract in vitro and in vivo in human cervical cancer. The scratch assay and Boyden Chamber assay were used to determine the anti-migrative and anti-invasion actions of the plant extract. The whole-genome gene expression profiling using RNA-Seq was performed to determine the differentially expressed genes in CaSki cells after exposure to I. cylindrica to identify its targeted genes related to metastasis. Using protein analysis (western blotting) and gene expression analysis (RTqPCR), the targeted pathways of the key genes that were initially identified with RNA-Seq, were evaluated. RESULTS I. cylindrica extract showed dose-dependent cytotoxicity in vitro and in vivo in mice bearing tumors. Furthermore, I. cylindrica root extract significantly inhibited cell migration and cell invasion. After the genome-wide transcriptome analysis, we found that important genes involved in cancer progression and metastasis of cervical cancer, that is, CD24 and TIMP-4 were significantly downregulated and upregulated, respectively. Moreover, I. cylindrica root extract significantly inhibited the PI3/AKT/Snail signaling pathway and blocked the EMT of CaSki cells. CONCLUSION These findings provide an anti-metastatic mechanism of action of I. cylindrica root extract toward the human cervical cancer suggesting that this plant maybe developed into selective chemotherapy.

Abstract
To explore the mechanism of miR-202-5p targeting the expression of PIK3CA and mediating the activation of PI3K/Akt/mTOR signaling pathway on the proliferation, invasion, and epithelial-mesenchymal transition (EMT) of cervical cancer. The objects of study were 105 cases of cervical cancer and their corresponding normal tissues. qRT-PCR was used to detect the expression of miR-202-5p and PIK3CA in adjacent normal tissue and cervical cancer tissue. Dual luciferase reporter assay was used to verify the targeting relationship between miR-202-5p and PIK3CA gene. Human cervical cancer cell lines HPV-16E6, SiHa, HeLa, and CaSki were purchased for our cell experiments. The expression levels of PIK3CA in the cells were detected by qRT-PCR. The cell line with higher expression levels was selected to complete the follow-up experiment. The cultured cells were transfected and divided into the miR-202-5p mimic NC group, miR-202-5p mimic group, miR-202-5p inhibitor NC group, miR-202-5p inhibitor group, siRNA-PIK3CA NC group, siRNA-PIK3CA group, miR-202-5p inhibitor NC + siRNA-PIK3CA NC group, miR-202-5p inhibitor + siRNA-PIK3CA NC group, and miR-202-5p inhibitor + siRNA-PIK3CA group. QRT-PCR was used to detect the expression of miR-202-5p. Western blot and qRT-PCR were applied to detect the mRNA and protein expression levels of related pathway proteins (PIK3CA, PI3K, PTEN, p-Akt1, and p-mTOR) and epithelial-mesenchymal transition-related factors (N-cadherin, E-cadherin, and vimentin). Cell proliferation was detected by plate colony formation assay. Transwell assay was used to detect the invasion ability of each group. When compared with the adjacent tissues, PIK3CA mRNA expression level was significantly increased and miR-202-5p expression level was significantly decreased in cervical cancer tissues (all P < 0.05). PIK3CA was a target gene of miR-202-5p. The mRNA expression level of PIK3CA in SiHa cervical cancer cells was significantly higher than that in CaSki, HeLa, and HPV-16E6 cells (all P < 0.05), and SiHa cervical cancer cells were selected to complete the follow-up experiments. When compared with the corresponding NC group, the expression of miR-202-5p in miR-202-5p mimic group was increased. In addition, the mRNA and protein expression levels of E-cadherin and PTEN in miR-202-5p mimic and siRNA-PIK3CA groups were increased, and the protein expression of p-Akt1 and p-mTOR was decreased, and also, the mRNA and protein expression levels of PIK3CA, PI3K, N-cadherin, and vimentin were decreased (all P < 0.05); in miR-202-5p inhibitor group, the expression levels of miR-202-5p, E-cadherin, and PTEN decreased, the protein expression of p-Akt1 and p-mTOR increased, and the mRNA and protein expression of PIK3CA, PI3K, N-cadherin, and vimentin increased in miR-202-5p inhibitor group (all P < 0.05); in miR-202-5p inhibitor + siRNA-PIK3CA group, the expression of miR-202-5p decreased (P < 0.05), but the mRNA and protein expression of PIK3CA, PI3K, p-Akt1, p-mTOR, N-cadherin, E-cadherin, and vimentin had no significant changes (all P > 0.05). When compared with the corresponding NC group, the number of cell clones in miR-202-5p mimic group and siRNA-PIK3CA group was decreased, and the invasion ability of miR-202-5p inhibitor group was increased, and the invasion ability was enhanced (all P < 0.05); miR-202-5p inhibitor + siRNA-PIK3CA group showed no significant change in the number of cell clones and the rate of invasion (P > 0.05). In conclusion, the overexpression of miR-202-5p can suppress PIK3CA gene expression and the activation of PI3K/Akt/mTOR signaling pathway to suppress the proliferation, invasion, and EMT of cervical cancer.

Inhibiting the redox function of APE1 suppresses cervical cancer metastasis via disengagement of ZEB1 from E-cadherin in EMT. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2021; 40:220. [PMID: 34210327 PMCID: PMC8246661 DOI: 10.1186/s13046-021-02006-5] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Accepted: 06/06/2021] [Indexed: 01/06/2023]
Abstract
BACKGROUND Metastasis is a major challenge in cervical cancer treatment. Previous studies have shown that the dual functional protein apurinic/apyrimidinic endonuclease 1 (APE1) promotes tumor metastasis and is overexpressed in cervical cancer. However, the biological role and mechanism of APE1 in cervical cancer metastasis have rarely been studied. METHODS We used gene set enrichment analysis (GSEA) to determine the APE1-related signaling pathways in cervical cancer. To investigate the role and mechanism of APE1 in cervical cancer metastasis and invasion, immunohistochemistry, immunofluorescence, western blotting, secondary structure prediction, coimmunoprecipitation, luciferase reporter, and electrophoretic mobility shift assays were performed. The inhibitory effects of the APE1 redox function inhibitor APX3330 on cervical cancer metastasis were evaluated using animal models. RESULTS Clinical data showed that high expression of APE1 was associated with lymph node metastasis in cervical cancer patients. GSEA results showed that APE1 was associated with epithelial to mesenchymal transition (EMT) in cervical cancer. Ectopic expression of APE1 promoted EMT and invasion of cervical cancer cells, whereas inhibition of APE1 suppressed EMT and invasion of cervical cancer cells in a redox function-dependent manner. Notably, APE1 redox function inhibitor APX3330 treatment dramatically suppressed cervical cancer cell lymph node and distant metastasis in vivo. Furthermore, we found that APE1 enhanced the interaction between ZEB1 and the E-cadherin promoter by binding to ZEB1, thereby suppressing the expression of E-cadherin, a negative regulator of EMT. CONCLUSION Our findings help to elucidate the role played by APE1 in cervical cancer metastasis and targeting APE1 redox function may be a novel strategy for inhibiting cervical cancer metastasis.

Abstract
BACKGROUND/AIM This study aimed to evaluate the outcome of radiation therapy for patients with distant lymph node (LN) metastases, without organ metastases from uterine cervical cancer (UCC). PATIENTS AND METHODS Twenty-six patients with UCC with distant LN metastases received radiotherapy and were retrospectively analyzed. The sites of distant LN metastasis were as follows; Supraclavicular in 19, inguinal in nine, axillary in four, and others in three. The mean dose prescribed for these was 50 (range=40-60) Gy. RESULTS The 2-year overall, cause-specific, and progression-free survival, and local control of primary tumor rates were 51.3%, 51.3%, 46.9%, and 67.9%. In multivariate analysis, performance status ≥1 (p=0.007), para-aortic LN metastases (p=0.001), and lack of high-dose-rate intracavitary brachytherapy (p=0.033) were significantly associated with poor overall survival. Performance status ≥1 (p=0.004), and para-aortic LN metastases (p=0.014) were significantly associated with poor cause-specific survival. CONCLUSION This study demonstrated favorable local control in patients with UCC with distant LN metastases.

Abstract
OBJECTIVE To analyze the role of circMYC in cervical cancer. METHODS Protein and RNA expression was detected by RT-qPCR and western blotting. Transwell, CCK8, and colony formation assays were used for measuring metastasis, cell viability, and proliferation, respectively. Lactate production, glucose uptake, and ATP generation were examined to evaluate cell glycolysis. Interactions between circMYC, miR-577, and MET were determined by RNA pull-down and immunoprecipitation, and dual-luciferase reporter assays. Xenografts were established in mice to evaluate the functions of circMYC in vivo. RESULTS circMYC was overexpressed in tumor tissue, which was related to poor prognosis. CircMYC knockdown reduced proliferation, colony formation, metastasis, and glycolysis in cervical cancer cells as well as inhibiting tumor growth in vivo. Mechanistically, circMYC targeted miR-577, and the effects of circMYC knockdown could be reversed by miR-577 inhibition. Moreover, miR-577 downregulated the expression of MET. Therefore, the oncogenic role of circMYC in cervical cancer was achieved by sponging miR-577 and maintaining MET expression. CONCLUSION circMYC promotes cervical cancer progression through regulation of the miR-577/MET axis. circMYC may thus be a potential target for diagnosing and treating cervical cancer.

[PMID: 34222242 PMCID: PMC8248809 DOI: 10.3389/fcell.2021.670890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 04/09/2021] [Indexed: 11/13/2022] Open
Abstract
Objective To clarify the clinical relevance of WASP like actin nucleation promoting factor (WASL) in patients with cervical cancer and associated mechanisms. Methods and Materials We obtained high prediction accuracy and determined the correlation between the expression of WASL and the clinical characteristics of cervical cancer patients. Differentially expressed genes (DEGs) were identified using microarray. Gene ontology (GO) enrichment analysis and gene set enrichment analysis (GSEA) were performed to determine potentially relevant mechanisms related to the prognostication ability of WASL expression. Results Chi-square test and multivariable logistic regression analysis suggested that lower expression of WASL was associated with lower pathological stage (chi-square test: p = 0.022, chi-square = 9.613; logistic regression: OR = 0.869, 95% CI: 0.756-0.991, p = 0.041). Patients in the WASL high expression group have worse overall survival (OS) [hazard ratio (HR): 0.555, 95% CI: 0.348-0.884, log-rank p = 0.012] and recurrence-free survival (RFS) (HR = 0.449, 95% CI: 0.215-0.934, log-rank p = 0.028) compared with those in the WASL low expression group. Univariate and multivariable Cox proportional hazards regression model suggested that WASL expression was an independent prognostic factor for predicting OS and RFS in cervical cancer. DEGs were mostly enriched GO terms related to DNA replication or the proliferation of tumor cells. The results of GSEA suggested samples in the WASL knockdown group were enriched in glycolysis, TNF-α signaling via NFkB, mTORC1 signaling, and Wnt/β-catenin signaling. Conclusions WASL expression was associated with the pathological stage, and it might be an independent prognostication factor in patients with cervical cancer. Knockdown of WASL might be correlated with biological processes such as glycolysis, TNFα signaling, mTOR signaling, and Wnt/β-catenin signaling.
