Ye Y, Lian R, Li Z, Chen X, Huang Y, Yao J, Lu A, Lang J, Liu P, Chen C. Predictive value of number of metastatic lymph nodes and lymph node ratio for prognosis of patients with FIGO 2018 stage IIICp cervical cancer: a multi-center retrospective study. BMC Cancer 2024; 24:1005. [PMID: 39138415 PMCID: PMC11320992 DOI: 10.1186/s12885-024-12784-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 08/08/2024] [Indexed: 08/15/2024] Open
Abstract
BACKGROUND To identify the cut-off values for the number of metastatic lymph nodes (nMLN) and lymph node ratio (LNR) that can predict outcomes in patients with FIGO 2018 IIICp cervical cancer (CC). METHODS Patients with CC who underwent radical hysterectomy with pelvic lymphadenectomy were identified for a propensity score-matched (PSM) cohort study. A receiver operating characteristic (ROC) curve analysis was performed to determine the critical nMLN and LNR values. Five-year overall survival (OS) and disease-free survival (DFS) rates were compared using Kaplan-Meier and Cox proportional hazard regression analyses. RESULTS This study included 3,135 CC patients with stage FIGO 2018 IIICp from 47 Chinese hospitals between 2004 and 2018. Based on ROC curve analysis, the cut-off values for nMLN and LNR were 3.5 and 0.11, respectively. The final cohort consisted of nMLN ≤ 3 (n = 2,378) and nMLN > 3 (n = 757) groups and LNR ≤ 0.11 (n = 1,748) and LNR > 0.11 (n = 1,387) groups. Significant differences were found in survival between the nMLN ≤ 3 vs the nMLN > 3 (post-PSM, OS: 76.8% vs 67.9%, P = 0.003; hazard ratio [HR]: 1.411, 95% confidence interval [CI]: 1.108-1.798, P = 0.005; DFS: 65.5% vs 55.3%, P < 0.001; HR: 1.428, 95% CI: 1.175-1.735, P < 0.001), and the LNR ≤ 0.11 and LNR > 0.11 (post-PSM, OS: 82.5% vs 76.9%, P = 0.010; HR: 1.407, 95% CI: 1.103-1.794, P = 0.006; DFS: 72.8% vs 65.1%, P = 0.002; HR: 1.347, 95% CI: 1.110-1.633, P = 0.002) groups. CONCLUSIONS This study found that nMLN > 3 and LNR > 0.11 were associated with poor prognosis in CC patients.

Abstract
BACKGROUND To compare the oncological outcomes of radical chemotherapy (R-CT), abdominal radical hysterectomy (ARH), and neoadjuvant chemotherapy and radical surgery (NACT) for International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIIC cervical cancer, according to histological types: squamous cell carcinoma (SCC) and adenocarcinoma (AC)/adenosquamous cell carcinoma (ASC). METHODS A comparison of 5-year overall survival (OS) and disease-free survival (DFS) was performed for the SCC and AC/ASC subgroups for the three initial treatments, assessed using Kaplan-Meier and Cox proportional hazards regression analysis and validated using propensity score matching (PSM). RESULTS The study included 4086 patients: R-CT, n = 1913; ARH, n = 1529; and NACT, n = 644. AC/ASC had a lower survival rate (63.7%) than SCC (73.6%) and a higher recurrence and mortality rate (36.3% and 26.4%, respectively). The 5-year OS and DFS rates were different in the SCC group for R-CT, ARH, and NACT (OS: 69.8% vs. 80.8% vs. 73.0%, p < 0.001; DFS: 66.7% vs. 70.7% vs. 56.4%, p < 0.001), also in the AC/ASC group (OS: 46.1% vs. 70.6% vs. 55.6%, p < 0.001; DFS: 42.7% vs. 64.6% vs. 40.8%, p < 0.001). As for initial treatment, survival outcomes were worse for AC/ASC treated with R-CT and ARH than for SCC (both p < 0.05), with no group differences between the two treated with NACT. CONCLUSION Initial treatment influences oncological prognosis for patients with FIGO 2018 stage IIIC cervical cancer. ARH is an alternative treatment for stage IIIC cervical SCC and AC/ASC, and NACT needs to be chosen with caution, moreover, R-CT for AC/ASC requires careful selection.

[PMID: 34399848 PMCID: PMC8365943 DOI: 10.1186/s40709-021-00151-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 07/27/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND Cervical cancer (CC) is one of the most common and malignant tumors in women. In this study, we aim to explore the role and mechanism of F-box and leucine rich repeat protein 19 antisense RNA 1 (FBXL19-AS1), a novel long-chain non coding RNA (lncRNA) with marked roles in a variety of tumors, in regulating the proliferation and metastasis of CC. METHODS The expression of FBXL19-AS1, miR-193a-5p and COL1A1 were detected by RT-PCR and western blot. Gain- and loss-of functional assays of FBXL19-AS1 and miR-193a-5p were performed in CC cell lines in vitro or in vivo. The proliferation, migration, invasion, apoptosis and epithelial-mesenchymal transition (EMT) of CC cells were determined. RESULTS FBXL19-AS1 and COL1A1 were significantly up-regulated in CC tissues, while miR-193a-5p was significantly down-regulated. Overexpression of FBXL19-AS1 significantly promoted the proliferation, migration, invasion, EMT and growth of CC cells and inhibited apoptosis, while knockdown of FBXL19-AS1 had the opposite effects. On the other hand, miR-193a-5p inhibited the proliferation and metastasis of CC cells. Mechanistically, FBXL19-AS1 functioned as a competitive endogenous RNA (ceRNA) and inhibited the expression of miR-193a-5p, which targeted at the 3'-UTR site of COL1A1 and negatively regulated COL1A1 expression. CONCLUSIONS FBXL19-AS1 promotes the proliferation and metastasis of CC cells by sponging miR-193a-5p and up-regulating COL1A1.

[PMID: 34238315 PMCID: PMC8264971 DOI: 10.1186/s12967-021-02963-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Accepted: 06/25/2021] [Indexed: 12/02/2022] Open
Abstract
Background Metastasis and invasion are crucial in determining the mortality of cervical carcinoma (CC) patients. The epithelial–mesenchymal transition (EMT) is now a universal explanation for the mechanisms of tumor metastasis. Α-chimeric protein (α-chimaerin, CHN1) plays an important role in the regulation of signal transduction and development. However, the molecular regulatory relationships between CHN1 and CC progression in relation to EMT have not yet been identified. Methods The expression of CHN1 in CC tissues, adjacent tissues, and lymph node metastases from CC patients was detected by immunohistochemistry. Upregulation and knockdown of CHN1 were achieved by transfection of CC cells. The effect of CHN1 on cell proliferation was determined by CCK-8 and plate clone formation assays. Changes in migration and invasion capabilities were evaluated using scratch migration and transwell invasion assays. The effect of CHN1 overexpression and interference on xenograft tumor growth was determined by tumor weight and pathological analyses. The expression of EMT-related mRNAs was measured by qRT-PCR in transfected CC cells. EMT-related proteins and Akt/GSK-3β/Snail signaling pathway-related proteins were also evaluated by western blotting. Results CHN1 was overexpressed in CC tissues and was associated with lymph node metastasis and low survival in CC patients. Overexpression of CHN1 promoted cell proliferation, migration, and invasion in CC cells. In contrast, silencing of CHN1 inhibited these phenomena. Overexpression of CHN1 promoted tumor formation in an in vivo xenograft tumor mouse model, with increased tumor volumes and weights. In addition, CHN1 induced the expression of EMT-related transcription factors, accompanied by the decreased expression of epithelial markers and increased expression of mesenchymal markers. The Akt/GSK-3β/Snail signaling pathway was activated by overexpression of CHN1 in vitro, and activation of this pathway was inhibited by the signaling pathway inhibitor LY294002. Conclusion These results suggest that CHN1 promotes the development and progression of cervical carcinoma via the Akt/GSK-3β/Snail pathway by inducing EMT.

Overexpression of TGF-β1 and SDF-1 in cervical cancer-associated fibroblasts promotes cell growth, invasion and migration. Arch Gynecol Obstet 2021; 305:179-192. [PMID: 34196798 DOI: 10.1007/s00404-021-06137-0] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Accepted: 06/23/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVE The purpose of this study was to investigate the effect of overexpression of transforming growth factor β1 (TGF-β1) and stromal cell-derived factor 1 (SDF-1) in cervical cancer-associated fibroblasts (CAFs) on regulating cell growth, invasion and migration. METHODS CAF cells and normal fibroblast cells (NFs) were obtained from patients with cervical squamous cell carcinoma and multiple uterine leiomyomas, respectively. Immunofluorescence assay and western blot were used to determine the expression of Vimentin and α-smooth muscle actin (α-SMA). CCK-8 assay was used to detect cell viability. Giemsa dyer was used to detect the colony formation. Flow cytometry was used to detect the growth state of cells. Transwell assays were used to detect the migration and invasion. RESULTS Vimentin and α-SMA expression in CAFs were significantly increased than those in NFs. In addition, TGF-β1 and SDF-1 expression were notably increased, and transforming growth factor beta receptor 2 (TβRII) expression was markedly decreased in CAF cells than those in NFs. Similarly, TGF-β1 and SDF-1 expression in the co-culture of CAFs and Hela cells were significantly increased, and cell proliferation, migration, invasion, colony formation and cell cycle progression were also promoted, while cell apoptosis was decreased. Those phenomena were reversed in the co-culture system with neutralizing antibodies to TGF-β1 and SDF-1. Furthermore, exogenous TGF-β1 and SDF-1 enhanced proliferation, colony formation, cell cycle progression, migration and invasion while decreased apoptosis of cells. These phenomena were also reversed by the addition of neutralizing antibodies to TGF-β1 and SDF-1. CONCLUSION Overexpression of TGF-β1 and SDF-1 in CAFs can promote the growth, invasion and migration of cervical cancer cells.

Abstract
BACKGROUND Emerging research has demonstrated that long non-coding RNAs (lncRNAs) attach great importance to the progression of cervical cancer (CC). LncRNA ARAP1-AS1 was involved in the development of several cancers; however, its role in CC is far from being elucidated. METHODS Real-time PCR (RT-PCR) was employed to detect ARAP1-AS1 and miR-149-3p expression in CC samples. CC cell lines (HeLa and C33A cells) were regarded as the cell models. The biological effect of ARAP1-AS1 on cancer cells was measured using CCK-8 assay, colony formation assay, flow cytometry, Transwell assay and wound healing assay in vitro, and subcutaneous xenotransplanted tumor model and tail vein injection model in vivo. Furthermore, interactions between ARAP1-AS1 and miR-149-3p, miR-149-3p and POU class 2 homeobox 2 (POU2F2) were determined by bioinformatics analysis, qRT-PCR, Western blot, luciferase reporter and RNA immunoprecipitation assay, respectively. RESULTS The expression of ARAP1-AS1 was enhanced in CC samples, while miR-149-3p was markedly suppressed. Additionally, ARAP1-AS1 overexpression enhanced the viability, migration, and invasion of CC cells. ARAP1-AS1 downregulated miR-149-3p via sponging it. ARAP1-AS1 and miR-149-3p exhibited a negative correlation in CC samples. On the other hand, ARAP1-AS1 enhanced the expression of POU2F2, which was validated as a target gene of miR-149-3p. CONCLUSION ARAP1-AS1 was abnormally upregulated in CC tissues and indirectly modulated the POU2F2 expression via reducing miR-149-3p expression. Our study identified a novel axis, ARAP1-AS1/miR-149-3p/POU2F2, in CC tumorigenesis.

Abstract
PURPOSE To clarify the prognostic value of the number of metastatic lymph nodes (mLNs) in squamous and non-squamous histologies among women with node-positive cervical cancer. METHODS One hundred ninety-one node-positive cervical cancer patients who had undergone radical hysterectomy plus systematic pelvic and para-aortic lymphadenectomy followed by concurrent radiochemotherapy were retrospectively reviewed. The prognostic value of the number of mLNs was investigated in squamous cell carcinoma (SCC) v (n = 148) and non-SCC (n = 43) histologies separately with univariate log-rank test and multivariate Cox regression analyses. RESULTS In SCC cohort, mLNs > 2 was significantly associated with decreased 5-year disease-free survival (DFS) [hazard ratio (HR) = 2.06; 95% confidence interval (CI) 1.03-4.09; p = 0.03) and overall survival (OS) (HR = 2.35, 95% CI 1.11-4.99; p = 0.02). However mLNs > 2 had no significant impact on 5-year DFS and 5-year OS rates in non-SCC cohort (p = 0.94 and p = 0.94, respectively). We stratified the entire study population as SCC with mLNs ≤ 2, SCC with mLNs > 2, and non-SCC groups. Thereafter, we compared survival outcomes. The non-SCC group had worse 5-year OS (46.8% vs. 85.3%, respectively; p < 0.001) and 5-year DFS rates (31.6% vs. 82.2%, respectively; p < 0.001) when compared to those of the SCC group with mLNs ≤ 2. However, the non-SCC group and the SCC group with mLNs > 2 had similar 5-year OS (46.8% vs. 65.5%, respectively; p = 0.16) and 5-year DFS rates (31.6% vs. 57.5%, respectively; p = 0.06). CONCLUSION Node-positive cervical cancer patients who have non-SCC histology as well as those who have SCC histology with mLNs > 2 seem to have worse survival outcomes when compared to women who have SCC histology with mLNs ≤ 2.

Abstract
Cervical cancer (CC) is a gynecological malignant tumor. Circular RNA (hsa_circ_0001772) (circRBM33) is implicated in the tumorigenesis of cancers. Nevertheless, the role of circRBM33 in CC is indistinct. Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to evaluate the levels of circRBM33, miR-758-3p, and pumilio RNA binding family member 2 (PUM2) mRNA in tissue samples and cells. Cell proliferation, apoptosis, migration, invasion, and glycolysis were assessed using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, flow cytometry assay, transwell assay, or special commercial kits. Relative protein levels were examined via western blotting. The targeting relationship between circRBM33 or PUM2 and miR-758-3p was verified via dual-luciferase reporter or RNA pull-down assays. The role of circRBM33 was confirmed via tumor formation experiments. CircRPPH1 and PUM2 were upregulated while miR-758-3p was downregulated in CC tissues and cells. Functionally, circRBM33 knockdown constrained tumor growth in vivo and cured CC cell proliferation, migration, invasion, glycolysis, and fostered CC cell apoptosis in in vitro. Mechanistically, circRBM33 sponged miR-758-3p to modulate PUM2 expression. MiR-758-3p inhibitor neutralized circRBM33 silencing-mediated effects on the malignant behaviors of CC cells. PUM2 elevation overturned the suppressive influence of miR-758-3p upregulation on the malignant behaviors of CC cells. CircRBM33 fostered CC advancement via absorbing miR-758-3p and upregulating PUM2, indicating that circRBM33 was a possible target for CC treatment.

Abstract
Purpose To determine the feasibility of texture analysis of apparent diffusion coefficient (ADC) maps and to assess the performance of texture analysis and ADC to predict histologic grade, parametrial invasion, lymph node metastasis, International Federation of Gynecology and Obstetrics (FIGO) stage, recurrence, and recurrence-free survival (RFS) in patients with cervical carcinoma. Materials and Methods This retrospective study included 58 patients with cervical carcinoma who were examined with a 1.5-T MRI system and diffusion-weighted imaging with b values of 0 and 1000 sec/mm2. Software with volumes of interest on ADC maps was used to extract 45 texture features, including higher-order texture features. Receiver operating characteristic (ROC) analysis was performed to compare the diagnostic performance of ADC map random forest models and of ADC values. Dunnett test, Spearman rank correlation coefficient, Kaplan-Meier analyses, log-rank test, and Cox proportional hazards regression analyses were also used for statistical analyses. Results The ADC map random forest models showed a significantly larger area under the ROC curve (AUC) than the AUC of ADC values for predicting high-grade cervical carcinoma (P = .0036), but not for parametrial invasion, lymph node metastasis, stages III-IV, and recurrence (P = .0602, .3176, .0924, and .5633, respectively). The random forest models predicted that the mean RFS rates were significantly shorter for high-grade cervical carcinomas, parametrial invasion, lymph node metastasis, stages III-IV, and recurrence (P = .0405, < .0001, .0344, .0001, and .0015, respectively); the random forest models for parametrial invasion and stages III-IV were more useful than ADC values (P = .0018) for predicting RFS. Conclusion The ADC map random forest models were more useful for noninvasively evaluating histologic grade, parametrial invasion, lymph node metastasis, FIGO stage, and recurrence and for predicting RFS in patients with cervical carcinoma than were ADC values.Keywords: Comparative Studies, Genital/Reproductive, MR-Diffusion Weighted Imaging, MR-Imaging, Neoplasms-Primary, Pathology, Pelvis, Tissue Characterization, UterusSupplemental material is available for this article.© RSNA, 2020See also the commentary by Reinhold and Nougaret in this issue.

Up-regulation of miRNA-148a inhibits proliferation, invasion, and migration while promoting apoptosis of cervical cancer cells by down-regulating RRS1. Biosci Rep 2019; 39:BSR20181815. [PMID: 30910849 PMCID: PMC6505193 DOI: 10.1042/bsr20181815] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 03/03/2019] [Accepted: 03/04/2019] [Indexed: 02/07/2023] Open
Abstract
The purpose of the present study is to figure out the role of miRNA-148a (miR-148a) in growth, apoptosis, invasion, and migration of cervical cancer cells by binding to regulator of ribosome synthesis 1 (RRS1). Cervical cancer and adjacent normal tissues, as well as cervical cancer cell line Caski, HeLa, C-33A, and normal cervical epithelial cell line H8 were obtained to detect the expression of miR-148a and RRS1. Relationship between miR-148a and RRS1 expression with clinicopathological characteristics was assessed. The selected Caski and HeLa cells were then transfected with miR-148a mimics, miR-148a inhibitors or RRS1 siRNA to investigate the role of miR-148a and RRS1 on proliferation, apoptosis, colony formation, invasion, and migration abilities of cervical cancer cells. Bioinformatics information and dual luciferase reporter gene assay was for used to detect the targetting relationship between miR-148a and RRS1. Down-regulated miR-148a and up-regulated RRS1 were found in cervical cancer tissues and cells. Down-regulated miR-148a and up-regulated RRS1 are closely related with prognostic factors of cervical cancer. RRS1 was determined as a target gene of miR-148a and miR-148a inhibited RRS1 expression in cervical cancer cells. Up-regulation of miR-148a inhibited cell proliferation, migration, and invasion while promoting apoptosis in Caski and HeLa cells. Our study suggests that miR-148a down-regulates RRS1 expression, thereby inhibiting the proliferation, migration, and invasion while promoting cell apoptosis of cervical cancer cells.

Abstract
Purpose This study was aimed to investigate the role of poly(A)-binding protein-interacting protein 1 (Paip1) in cervical carcinogenesis. Materials and Methods The expression of Paip1 in normal cervical epithelial tissues and cervical cancer (CC) tissues were detected by immunohistochemistry. In vivo and in vitro assays were performed to validate effect of Paip1 on CC progression. Results Paip1 was found to be up-regulated in CC, which was linked with shorter survival. Knockdown of Paip1 inhibited cell growth, induced apoptosis and cell cycle arrest in CC cells, whereas its overexpression reversed these effects. The in vivo tumor model confirmed the pro-tumor role of Paip1 in CC growth. Conclusion Altogether, the investigation demonstrated the clinical significance of Paip1 expression, which prompted that the up-regulated of Paip1 can presumably be a potential prognostic and progression marker for CC.

Interference of the long noncoding RNA CDKN2B-AS1 upregulates miR-181a-5p/TGFβI axis to restrain the metastasis and promote apoptosis and senescence of cervical cancer cells. Cancer Med 2019; 8:1721-1730.

Abstract
Long noncoding RNA (lncRNA) CDKN2B-AS1 has been shown to play a crucial role in the development as well as in the prognosis of various human cancers, including cervical cancer. However, the underlying mechanisms need to be further explored between CDKN2B-AS1 and cervical cancer. In the present study, RT-PCR showed that the mRNA level of CDKN2B-AS1 was significantly upregulated while the miR-181a-5p was downregulated in cervical cancer cell lines. In addition, the interference of CDKN2B-AS1 by shRNA resulted in the suppression of cell proliferation, invasion, migration and promotion of apoptosis and senescence, and either CDKN2B-AS1 overexpression or miR-181a-5p showed reversed results. Further studies demonstrated that CDKN2B-AS1 could directly interact with miR-181a-5p, and that there was an inverse correlation between miR-181a-5p and CDKN2B-AS1. In addition, we found that TGFβI was a target of miR-181a-5p and could be downregulated by CDKN2B-AS1 knockdown. Moreover, the in vivo experiments further demonstrated the contribution of CDKN2B-AS1 in cervical cancer including tumor growth, apoptosis inhibition and senescence inhibition, and CDKN2B-AS1 knockdown could inhibit the aforementioned activities. In summary, our study demonstrated that the CDKN2B-AS1/miR-181a-5p/TGFβI axis might play a vital role in cervical cancer development.

Expression levels of the long noncoding RNA steroid receptor activator promote cell proliferation and invasion and predict patient prognosis in human cervical cancer. Oncol Lett 2018; 16:5410-5418. [PMID: 30250612 DOI: 10.3892/ol.2018.9265] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Accepted: 07/26/2018] [Indexed: 01/23/2023] Open
Abstract
Long noncoding RNAs (lncRNAs) are involved in developmental processes and diseases and function as critical regulators of a number of different cancer types. Previous research has revealed that lncRNAs affect cervical cancer development. Steroid receptor activator (SRA), an lncRNA, serves as a critical regulator of gynecologic cancer. However, the association between SRA expression and cervical cancer remains unclear. In the present study, the SRA expression levels in patients with cervical cancer were examined and the association between SRA expression and clinicopathological factors was determined. SRA expression was observed in cervical cancer tissues (n=100) and corresponding normal tissues (n=22) using reverse transcription-quantitative polymerase chain reaction, and its associations with clinical parameters and prognosis were analyzed. SRA expression was significantly greater in tissues from patients with cervical cancer compared with in control patients (P<0.001). Multivariate analysis revealed that high SRA expression was an independent prognostic factor of overall survival (hazard ratio=3.714, P=0.031). The present study additionally investigated the biofunctional consequences of SRA overexpression in vitro using Cell Counting kit-8, wound healing migration and Matrigel invasion assays. The results demonstrated that SRA overexpression enhanced cell proliferation, migration and invasion in vitro. Furthermore, SRA overexpression induced the epithelial-mesenchymal transition (EMT). Therefore, SRA may promote tumor aggressiveness through the upregulation of EMT-associated genes. These results indicated that SRA may represent a novel biomarker for predicting recurrence and prognosis and serve as a promising therapeutic target in cervical cancer.

Abstract
BACKGROUND HOX transcript antisense RNA (HOTAIR) is a long non-coding RNA (lncRNA) widely involved in the progression of numerous malignancies. Whereas, the potential molecular mechanism of HOTAIR involved in cervical cancer progression is still needed to be elaborated. METHODS The expression of HOTAIR and miR-143-3p were detected in cervical cancer tissues and cells by qRT-PCR. MTT and flow cytometry analysis were performed to measure cell proliferation and apoptosis. Bioinformatics, Dual-Luciferase reporter and RIP were used to analyze the possible correlation between HOTAIR, miR-143-3p and BCL2. The expression of Bax and BCL2 was detected by western blot. Mice xenograft model was established to confirm the role of HOTAIR on tumor growth in vivo. RESULTS HOTAIR expression was elevated while miR-143-3p expression was reduced in cervical cancer tissues and cell lines. HOTAIR knockdown suppressed proliferation and enhanced apoptosis in cervical cancer cells. Moreover, HOTAIR could function as a sponge for miR-143-3p. The inhibitory effect of HOTAIR knockdown on cervical cancer cells growth was abolished following decrease of miR-143-3p expression. Furthermore, HOTAIR promoted BCL2 expression by modulating miR-143-3p. BCL2 overexpression attenuated the tumor-suppressive effect of miR-143-3p in cervical cancer. Finally, the carcinogenicity of HOTAIR was validated in mice. CONCLUSIONS HOTAIR promoted cervical cancer cell growth by modulating BCL2 via miR-143-3p, hinting a novel regulatory mechanism and potential therapeutic target in cervical cancer.

Abstract
Recent research has focused on the impact of long noncoding RNA (lncRNA) in cervical carcinogenesis. However, whether HOXA11 antisense (HOXA11-AS) is involved in cervical cancer remains to be elucidated. In the present study, we examined HOXA11-AS expression levels in cervical cancer patients and determined the relationships between HOXA11-AS expression and clinicopathological factors. We also investigated the bio-functional consequences of HOXA11-AS overexpression both in vitro and in vivo. HOXA11-AS expression was significantly greater in tissues from patients with cervical cancer than in control patients (P<0.001). Multivariate analysis showed that high HOXA11-AS was an independent prognosticator of overall survival (Hazard ratio=2.450, P=0.032). HOXA11-AS overexpression enhanced cell proliferation, migration, and tumor invasion in vitro, whereas HOXA11-AS knockdown inhibited these biologic aggressive features. These adverse changes were accompanied by characteristics of epithelial-mesenchymal transition (EMT). In vivo xenograft experiments using the siHOXA11-AS-transfected HeLa cells revealed that HOXA11-AS strongly induced tumor growth. Furthermore, we found that HOXA11-AS knockdown decreased cancer stemness and triggered the EMT program. In conclusion, HOXA11-AS overexpression correlated with poor survival in patients with cervical cancer. Thus, HOXA11-AS may be a pivotal target for exploring novel cervical cancer therapeutics.

Abstract
Contemporary research has focused on the function of long non-coding RNAs (lncRNAs) in carcinogenesis. However, the involvement of the lncRNA, steroid receptor RNA activator (SRA), in cervical carcinogenesis remains to be elucidated. In the present study, we investigated the bio-functional consequences of lncRNA SRA knockdown in vitro. To verify the role of lncRNA SRA in cell proliferation, migration, and invasion, lncRNA RNA interference was utilized to knock down lncRNA SRA expression in cervical cancer cell lines, resulting in our discovery that lncRNA SRA knockdown inhibited cell proliferation, cell migration and tumor invasion in the cervical cancer cell lines. Additionally, in vitro experiments using the lncRNA SRA-knockdown cervical cancer cell lines revealed that lncRNA SRA is a strong inducer and modulator of the expression of genes related to epithelial-mesenchymal transition and the NOTCH signaling pathway. In conclusion, our findings demonstrated that lncRNA SRA is highly correlated with cancer progression and cervical cancer cell proliferation and migration. Furthermore, these results indicate that lncRNA SRA may be a potential therapeutic target and prognostic marker for cervical malignancy.

Abstract
Background The aim of this study was to explore the relationships of HPIP expression status with the clinicopathological variables and survival outcomes of patients with cervical cancer (CC). Methods We compared the HPIP expression of 119 samples from CC tissues, 20 from cervical intraepithelial tissues, and 20 from normal cervical tissues by using immunohistochemical staining. Results It was observed that the ratio of elevated HPIP expression was higher in CC tissues than in cervical intraepithelial neoplasia (P=0.017) and normal cervical tissues (P=0.001). In addition, there was an association between HPIP and clinicopathological factors, such as histological grade (P<0.001), stromal infiltration (P=0.015), lymph node metastasis (P<0.001), lymphovascular space invasion (LVSI; P=0.026), and recurrence (P=0.029). Furthermore, multivariate Cox regression analysis revealed that high HPIP expression (P=0.027 and P=0.042) as well as the International Federation of Gynaecology and Obstetrics stage (P=0.003 and P=0.009), lymph node metastasis (P=0.031 and P=0.017), and LVSI (P=0.024 and P=0.046) were independent prognostic factors. In addition, we demonstrated that high HPIP expression (P=0.003) and LVSI (P<0.001) were independently related to lymph node metastasis. Conclusion Elevated HPIP expression may contribute to the progression and metastasis of CC and may also serve as a new biomarker to predict the prognosis of CC.

Abstract
Background The aim of the present study was to investigate the potential effects of the 5,10,15,20-tetrakis (1-methylpyridinium-4-yl) porphyrin (TMPyP4) on the proliferation and apoptosis of human cervical cancer cells and the underlying mechanisms by which TMPyP4 exerted its actions. Results After human cervical cancer cells were treated with different doses of TMPyP4, cell viability was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method, the apoptosis was observed by flow cytometry (FCM), and the expression of p38 mitogen-activated protein kinase (MAPK), phosphated p38 MAPK (p-p38 MAPK), capase-3, MAPKAPK2 (MK-2) and poly ADP-ribose polymerase (PARP) was measured by Western blot analysis. The analysis revealed that TMPyP4 potently suppressed cell viability and induced the apoptosis of human cervical cancer cells in a dose-dependent manner. In addition, the up-regulation of p-p38 MAPK expression levels was detected in TMPyP4-treated human cervical cancer cells. However, followed by the block of p38 MAPK signaling pathway using the inhibitor SB203580, the effects of TMPyP4 on proliferation and apoptosis of human cervical cancer cells were significantly changed. Conclusions It was indicated that TMPyP4-inhibited proliferation and -induced apoptosis in human cervical cancer cells was accompanied by activating the p38 MAPK signaling pathway. Taken together, our study demonstrates that TMPyP4 may represent a potential therapeutic method for the treatment of cervical carcinoma.

Abstract
Cervical cancer is the third most common cancer and the fourth leading cause of malignancy related mortality in women worldwide. CCL19 is highly expressed in human cancer cells, and ligand CCL19 binding to CCR7 induces actin polymerization and pseudopodia formation. However, whether or not CCL19 is involved in EMT of human cervical cancer needs further investigation. Using quantitative PCR and western blot analyses, we found that CCL19 is overexpressed in cervical cancer cell lines and tissues. Knockdown of CCL19 via siRNA inhibited the proliferation of cervical cancer cells by increasing apoptosis. Further analyses showed that inhibitory effects of CCL19 on cell migration and invasion were partly associated with EMT process. In conclusion, these data indicate that CCL19 is abnormally expressed in cervical cancer, indicating a novel and important role for CCL19 in cervical cancer malignant transformation.

Tripartite motif containing 62 is a novel prognostic marker and suppresses tumor metastasis via c-Jun/Slug signaling-mediated epithelial-mesenchymal transition in cervical cancer. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2016; 35:170. [PMID: 27793172 PMCID: PMC5084416 DOI: 10.1186/s13046-016-0445-5] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Accepted: 10/17/2016] [Indexed: 12/22/2022]
Abstract
Background TRIM62 (tripartite motif containing 62) has been found to act as a tumor suppressor of several cancers. However, its precise biological role and related mechanism remain unknown in cervical cancer (CC). Methods Quantitative Real-time PCR and western blot were adopted to detect the mRNA and protein expression level of TRIM62 in both human CC cell lines and tissues. Immunohistochemistry was used to measure the TRIM62 expression in 30 normal cervical and 189 CC tissues. Univariate and multivariate Cox regression analyses and Kaplan–Meier survival analyses performed to investigate the association between TRIM62 expression and CC patients’ prognosis. The effect of TRIM62 on CC growth and metastasis was studied in vitro and in vivo. Multi-pathway reporter array were utilized to identify the potential signaling manipulated by TRIM62. Results TRIM62 was frequently down-regulated in both human CC cells and tissues. Low expression of TRIM62 in CC tissues was associated with aggressive clinicopathological features of CC patients. In addition, TRIM62 was also an independent poor prognostic factor for overall and disease-free survival of CC patients after surgery. Moreover, enforced expression of TRIM62 in CC cells significantly inhibited their abilities of proliferation, migration and invasion in vitro. Besides, subcutaneous xenograft tumor model and xenograft mouse metastatic model respectively displayed that TRIM62 impeded the growth and metastasis of CC in vivo. Furthermore, mechanism study exhibited that TRIM62 could suppress epithelial-mesenchymal transition (EMT) by inhibiting c-Jun/Slug signaling. The inhibitory role of TRIM62 in tumor proliferation might be through regulating cell cycle related proteins CyclinD1 and P27 by targeting c-Jun. Conclusion TRIM62 is a potential prognostic biomarker in CC and suppresses metastasis of CC via inhibiting c-Jun/Slug signaling-mediated EMT.

Abstract
Transient receptor potential vanilloid 6 (TRPV6) has been shown to promote caner proliferation in several solid tumors, leading to unfavorable clinical outcomes. Our study aimed to elucidate the clinical significance of TRPV6 in patients with early-stage cervical squamous cell carcinoma (CSCC). The mRNA expression of TRPV6 was measured in 12 paired early-stage CSCC specimens and six cervical carcinoma cell lines using quantitative real-time PCR (qRT-PCR). Western blotting and immunohistochemistry (IHC) were employed to examine the protein expression level of TRPV6 in four paired specimens, 175 paraffin-embedded early-stage CSCC specimens, and 50 normal cervical tissues (NCTs), respectively. Statistical analyses were performed to evaluate the clinical significance of TRPV6 expression. The expressions of TRPV6 mRNA and protein were both significantly downregulated in early-stage CSCC tissues and cervical cancer cell lines. IHC analyses revealed that TRPV6 was downregulated in 136 (77.7 %) of 175 early-stage CSCC specimens. Moreover, TRPV6 expression in early-stage CSCC was significantly correlated with the tumor stage (P < 0.001), tumor growth type (P < 0.001), tumor size (P = 0.008), and differentiation grade (P = 0.003). The early-stage CSCC patients with a low TRPV6 expression level had a short progress-free survival (PFS) and overall survival (OS) duration. Univariate and multivariate analyses identified TRPV6 as an independent prognostic factor for early-stage CSCC patients' survival. We demonstrated that TRPV6 was downregulated in CSCC, which was correlated with unfavorable survival outcomes of early-stage CSCC patients. TRPV6 may be used as a novel prognostic marker for early-stage CSCC.

Abstract
The identification of cancer-associated long noncoding RNA (lncRNA) is critical for us to understand cancer pathogenesis and development. The aim of this study was to evaluate the expression profile of the lncRNA SPRY4-IT1 in cervical cancer and to identify its clinical significance in cancer progression. The expression levels of SPRY4-IT1 in cervical cancer tissues were measured by quantitative real-time PCR, and its correlation with overall survival of cervical cancer patients was analyzed statistically. Our results showed that the expression levels of SPRY4-IT1 were higher in cervical cancer tissues than in adjacent normal tissues. Patients with higher SPRY4-IT1 expression had advanced clinical characteristics and a shorter overall survival time than those with lower SPRY4-IT1 expression. Moreover, multivariate analysis showed that relative SPRY4-IT1 expression was an independent predictor of overall survival in patients with cervical cancer. In addition, the model we have established shows a good prediction of the probability of 5-year overall survival of patients according to the c-index and calibration curve. Collectively, our data suggest that lncRNA SPRY4-IT1 may be a novel molecule involved in cervical cancer progression, which may be of use as both a potential predictor and therapeutic target.

Abstract
Acylglycerol kinase (AGK) had been shown to contribute to cancer progression and unfavorable clinical outcomes of patients. Our study aimed to investigate the expression pattern and clinical significance of AGK in patients with early-stage cervical squamous cell cancer (CSCC). The protein and messenger RNA (mRNA) expression of AGK was analyzed in six cervical cancer cell lines and four paired early-stage CSCC specimens and normal cervical tissues (NCT), using Western blotting and real-time PCR (RT-PCR). And we investigated the AGK protein expression in paraffin-embedded specimens from 140 patients with early-stage CSCC and 30 cases of NCT by immunohistochemistry (IHC). Statistical analyses were performed to evaluate the clinicopathological significance of AGK expression. The expressions of AGK protein and mRNA were significantly up-regulated in cervical cancer cell lines and cancer tissues. IHC analyses revealed that AGK was highly expressed in 93 (66.4 %) of 140 early-stage CSCC specimens, but in none of the NCT. Moreover, AGK expression in early-stage CSCC was significantly correlated with tumor stage (P < 0.001), tumor size (P < 0.001), and tumor type (P < 0.001). Early-stage CSCC patients with high AGK expression level had shorter progress-free survival (PFS) and overall survival (OS) time compared with patients with low AGK expression levels. Univariate and multivariate analyses identified AGK expression level as an independent prognostic factor for survival of early-stage CSCC patients. We showed that AGK was over-expressed in cervical cancer cell lines and clinical tissues, and over-expression of AGK was associated with poor survival outcomes of early-stage CSCC patients. AGK can be used as an independent prognostic marker for early-stage CSCC.

Abstract
PURPOSE Using integrated PET/CT, we evaluated the prognostic relevance in uterine cervical cancer of preoperative pelvic lymph node (LN) [(18)F]FDG uptake. METHODS Patients with FIGO stage IB to IIA uterine cervical cancer were imaged with FDG PET/CT before radical surgery. We used Cox proportional hazards regression to examine the relationship between recurrence and the FDG maximum standardized uptake value (SUV(max)) in the pelvic LN (SUVLN) on PET/CT. RESULTS Clinical data, treatment modalities, and results in 130 eligible patients were reviewed. The median postsurgical follow-up was 34 months (range 6 to 109 months). Receiver operating characteristic analysis identified SUVLN 2.36 as the most significant cut-off value for predicting recurrence. SUV(LN) was correlated with SUV(tumour) (P = 0.002), primary tumour size (P = 0.004), and parametrial invasion (P = 0.013). Univariate analyses showed significant associations between recurrence and SUV(LN) (P = 0.001), SUV(tumour) (P = 0.007), pelvic LN metastasis (P = 0.002), parametrial invasion (P < 0.001), primary tumour size (P = 0.007), suspected LN metastasis on MRI (P = 0.024), and FIGO stage (P = 0.026). Multivariate analysis identified SUV(LN) (P = 0.013, hazard ratio, HR, 4.447, 95 % confidence interval, CI, 1.379 – 14.343) and parametrial invasion (P = 0.013, HR 6.728, 95 % CI 1.497 – 30.235) as independent risk factors for recurrence. Patients with SUV(LN) ≥ 2.36 and SUV(LN) <2.36 differed significantly in terms of recurrence (HR 15.20, P < 0.001). CONCLUSION Preoperative pelvic LN FDG uptake showed a strong significant association with uterine cervical cancer recurrence.

Abstract
The functions of many long non-coding RNAs (lncRNAs) in human cancers remain to be clarified. The lncRNA Hox transcript antisense intergenic RNA (HOTAIR) has been reported to reprogram chromatin organization and promote breast and colorectal cancer metastasis, the involvement of lncRNAs in cervical cancer is just beginning to be studied. In the present study, we examined the expression and the functional role of HOTAIR in cervical cancer. HOTAIR expression was determined in cervical cancer tissues (n=111) and corresponding normal tissues (n=40) by using real-time polymerase chain reaction, and its correlation with clinical parameters and prognosis were analyzed. To determine the effect of HOTAIR knockdown and overexpression in cervical cancer cell lines, we used the CCK-8 assay, wound healing migration and Matrigel invasion assay. The expression level of HOTAIR in cervical cancer tissues was higher than that in corresponding non-cancerous tissues. High HOTAIR expression correlated with lymph node metastasis, and reduced overall survival. A multivariate analysis showed that HOTAIR was a prognostic factor for predicting cervical cancer recurrence. Knockdown of HOTAIR reduced cell proliferation, migration, and invasion in cervical cancer cell lines. Moreover, HOTAIR regulated the expression of vascular endothelial growth factor, matrix metalloproteinase-9 and epithelial-to-mesenchymal transition (EMT)-related genes, which are important for cell motility and metastasis. Therefore, HOTAIR may promote tumor aggressiveness through the upregulation of VEGF and MMP-9 and EMT-related genes. These findings indicate that HOTAIR may represent a novel biomarker for predicting recurrence and prognosis and serve as a promising therapeutic target in cervical cancer.

Abstract
The CDGSH iron sulfur domain2 (CISD2) is an evolutionarily conserved gene. It functions to control mammalian life span and regulate human breast cancer cells proliferation. However, the characteristics of CISD2 expression and its clinical/prognostic significance are unclear in human tumor. Our study aimed to investigate the expression pattern and clinicopathological significance of CISD2 in patients with early-stage cervical cancer. The mRNA and protein expression levels of CISD2 were analyzed in eight cervical cancer cell lines and eight paired cervical cancer tumors by real-time PCR and Western blotting, respectively. Immunohistochemistry was performed to examine CISD2 protein expression in paraffin-embedded tissues from 149 early-stage cervical cancer patients. Statistical analyses were used to evaluate the clinicopathological significance of CISD2 expression. CISD2 expression was significantly upregulated in cervical cancer cells at both the mRNA and protein levels. Statistical analysis showed a significant correlation of CISD2 expression with the squamous cell carcinoma antigen (P = 0.000), myometrium invasion (P = 0.003), recurrence (P = 0.012), lymphovascular space involvement (P = 0.019) and especially pelvic lymph node metastasis (PLNM; P = 0.000). Patients with higher CISD2 expression had shorter overall survival duration than patients with lower CISD2 expression. Multivariate analysis suggested that CISD2 expression might be an independent prognostic indicator for the survival of patients with early-stage cervical cancer. Our results for the first time suggested that high CISD2 expression was closely correlated with PLNM and poor prognosis in early-stage cervical cancer patients. CISD2 protein might be a novel biomarker for early-stage cervical cancer progression.

Abstract
BACKGROUND Invasion and metastasis remain a critical issue in cervical cancer. However, the underlying mechanism of it in cervical cancer remains unclear. The newly discovered protein, TBLR1, plays a crucial role in regulating various key cellular functions. METHODS In this study, western blot, real-time RT-PCR, immunohistochemical staining, 3D morphogenesis Matrigel culture, wound healing and Boyden chamber invasion assays, xenografted tumour model, luciferase assays, and chromatin immunoprecipitation assays were used. RESULTS The expression of TBLR1 in cervical cancer cell lines and tissues was significantly upregulated at both the RNA and protein levels compared with that in normal cervical cells. Statistical analysis suggested that TBLR1 as an independent prognostic factor was significantly correlated with the clinical stage, survival time and recurrence. Moreover, overexpression of TBLR1 in Hela and Siha cell lines promoted invasion in vitro and in vivo with the increases of the mesenchymal factors vimentin and fibronectin and decreases of the epithelial marker α-catenin. In contrast, RNAi-mediated knockdown of TBLR1 inhibited epithelial-mesenchymal transition in vitro and in vivo. Further study indicated that this might be mediated via the NF-κB and Wnt/β-Catenin signalling pathway, and involve regulation of Snail and Twist. CONCLUSIONS The TBLR1 protein may be a prognostic marker in cervical cancer and play an important role in the invasion and metastasis of human cervical cancer.
