Abstract
BACKGROUND Cervical cancer is a human papillomavirus (HPV)-related disease. HPV type 16 (HPV16), which is the predominant cause of cervical cancer, can encode miRNAs (HPV16-miRNAs). However, the role of HPV16-miRNAs in the pathogenesis of cervical cancer remains unclear. METHODS Human cervical cancer cell lines SiHa (HPV16-positive) and C33A (HPV-negative), and cervical cancer tissues were collected to investigate the expression levels of two HPV16-miRNAs (HPV16-miR-H1 and HPV16-miR-H6). The overexpression and knockdown of HPV16-miR-H1 and HPV16-miR-H6 were performed using the lentiviral vector system and miRNA inhibitors, respectively. RNA-sequencing (RNA-seq) analysis and H3K27ac chromatin immunoprecipitation and sequencing (CHIP-seq) experiments were utilized to explore the roles of HPV16-miR-H1 and HPV16-miR-H6 facilitated by enhancers. CCK8, EdU, transwell, and wound healing assays were performed to verify the effects of HPV16-miR-H1 and HPV16-miR-H6 on cell proliferation and migration. RESULTS HPV16-miR-H1 and HPV16-miR-H6 were highly expressed in both SiHa cells and tissue samples from HPV16-positive cervical cancer patients. RNA-seq analysis showed that HPV16-miR-H1 and HPV16-miR-H6 induced the upregulation of numerous tumor progression-associated genes. H3K27ac CHIP-seq experiments further revealed that HPV16-miR-H1 and HPV16-miR-H6 modulated the expression of critical genes by regulating their enhancer activity. The functional study demonstrated that HPV16-miR-H1 and HPV16-miR-H6 increased the migratory capacity of SiHa cells. CONCLUSIONS Our data shed light on the role of HPV16-encoded miRNAs in cervical cancer, particularly emphasizing their involvement in the miRNA-enhancer-target gene system. This novel regulatory mechanism of HPV16-miRNAs provides new insights and approaches for the development of therapeutic strategies by targeting HPV16-positive cervical cancer.

[PMID: 37358427 PMCID: PMC10434196 DOI: 10.1128/spectrum.05117-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 06/01/2023] [Indexed: 06/27/2023] Open
Abstract
To investigate the relationship between single nucleotide polymorphisms (SNPs) in human papillomavirus (HPV) receptor associated genes and HPV susceptibility and clinical outcomes in Chinese women, from October 2016 to March 2020, a total of 3,066 women were recruited for a 3-year prospective population-based cervical cancer screening clinical trial. The primary endpoint was histological cervical intraepithelial neoplasia 2 and worse (CIN2+). Twenty-nine SNPs of HPV receptor associated genes on women with available cytology residual samples at baseline were detected using MALDI-TOF MS. Eligible data were available for 2,938 women. Rs16894821 (GG versus AA, OR =1.71 [1.08 to 2.69]) and rs724236 (TT versus AA, OR = 1.73 [1.14 to 2.62]) in SDC2 were significantly related to the HPV susceptibility. And rs2575712 (TT versus GG, OR = 2.78 [1.22 to 6.36]) in SDC2 was associated with increased HPV 16/18 susceptibility. Four SNPs (rs1047057 and rs10510097 in FGFR2 gene, rs2575735 in SDC2 gene, and rs878949 in HSPG2 gene) were significantly associated with persistent HPV infection. Importantly, the genotypes of rs16894821 under recessive model (GG versus AA/AG, OR = 2.40 [1.12 to 5.15]) in SDC2 and rs11199993 under dominant model (GC/CC versus GG, OR = 1.64 [1.01 to 2.68]) in FGFR2 were significantly associated with the disease progression. Finally, SNPs showed comparable efficacy in detecting CIN2+ for the women infected with non-HPV16/18 compared with cervical cytology (sensitivity: 0.51 [0.36 to 0.66] versus 0.44 [0.30 to 0.60], specificity: 0.96 [0.96 to 0.97] versus 0.98 [0.97 to 0.99], positive predictive value: 0.23 [0.15 to 0.33] versus 0.33 [0.22 to 0.47], and negative predictive value: 0.99 [0.98 to 0.99] versus 0.99 [0.98 to 0.99]). SNPs in HPV receptor related genes may influence HPV susceptibilities and clinical outcomes in Chinese women. IMPORTANCE Virus receptors are known to mediate virus attachment and further lead to virus infection of the host cells. In the current study, we investigated the relationship between single nucleotide polymorphisms (SNPs) in human papillomavirus (HPV) receptor associated genes and HPV susceptibility and clinical outcomes in Chinese women, and to explore the new triaging strategy for non-16/18 high-risk HPV infection.

Abstract
Long noncoding RNAs (lncRNAs) have been suggested as essential regulators in the cancer progression. LncRNA TUC338 was found to promote the malignancy of various cancers, however, the involvement of TUC338 in nasopharyngeal cancer (NPC) has not been well characterized. Here, our results found the significant overexpression of TUC338 in NPC tissues. Higher level of TUC338 was also observed in NPC cells. Interestingly, NPC patients harboring overexpressed TUC338 have worse prognosis. Functional study indicated that down-regulated TUC338 remarkably suppressed the NPC cell proliferation and cell migration. Notably, depletion of TUC338 significantly inhibited the in vivo tumor growth. Mechanistically, TUC338 acted as molecular sponge of miR-1226-3p and attenuated the negative regulation of miR-1226-3p on the expression of fibroblast growth factor 2 (FGF2). Down-regulation of TUC338 inhibited FGF2 expression in NPC cells and tumor tissues. Overexpression of FGF2 attenuated the suppressed NPC proliferation upon the depletion of TUC338. Our results demonstrated the novel function of TUC338/miR-1226-3p/FGF2 axis in NPC progression, suggesting the potential diagnosis and therapeutics significance of TUC338 in NPC.

Abstract
Background As a new type of molecular marker, microRNAs (miRNAs) can be used for early diagnosis and prognosis prediction of malignant tumors, and has broad clinical application prospects. This paper mainly studies the important role of miR-889 in the occurrence and development of hepatocellular carcinoma and the prognostic significance of miR-889 in hepatocellular carcinoma. Methods Quantitative real-time PCR analysis detected the expression levels of miR-889 in hepatocellular carcinoma tissues and cell lines. Kaplan-Meier curve and Cox regression analysis were used to explore the prognostic significance of miR-889 in hepatocellular carcinoma. The CCK-8 and Transwell assays assay were used to assess cell proliferation, migration, and invasion abilities ability. Results The expression of miR-889 in hepatocellular carcinoma tissues was significantly higher than that in adjacent tissues. Overexpression of miR-889 was significantly associated with TNM stage, hepatitis B virus infection, and cirrhosis. Patients with high miR-889 expression had shorter overall survival than those with low miR-889 expression. And functional studies in two hepatocellular carcinoma cell lines have shown that overexpression of miR-889 significantly promoted cell proliferation, migration, and invasion in vitro. Conclusions Overall, miR-889 was upregulated in hepatocellular carcinoma tissues and cell lines, and overexpression of miR-889 promoted cell proliferation, migration, and invasion in hepatocellular carcinoma cells. Based on our findings, high expression of miR-889 may promote the progression of hepatocellular carcinoma, and high expression of miR-889 is also forecasted for an unfavorable prognosis in hepatocellular carcinoma.

Abstract
Circular RNAs (circRNAs), a novel type of endogenous noncoding RNAs, have been identified as critical regulators in human carcinogenesis. Here, we investigated the precise actions of hsa_circ_0009035 in the progression and radioresistance of cervical cancer (CC). The levels of hsa_circ_0009035, microRNA 889-3p (miR-889-3p), and homeobox B7 (HOXB7) were detected by quantitative real-time PCR (qRT-PCR) or Western blotting. RNase R and actinomycin D assays were used to assess the stability of hsa_circ_0009035. Cell proliferation, cell cycle progression, apoptosis, migration, and invasion were gauged with Cell Counting Kit-8 (CCK-8), flow cytometry, and transwell assays. Cell colony formation and survival were determined by the colony formation assay. Targeted correlations among hsa_circ_0009035, miR-889-3p, and HOXB7 were examined by the dual-luciferase reporter, RNA immunoprecipitation (RIP), or RNA pulldown assay. Animal studies were performed to evaluate the impact of hsa_circ_0009035 on tumor growth. We found that hsa_circ_0009035 was highly expressed in CC tissues and cells, and it was associated with the radioresistance of CC patients. Moreover, the silencing of hsa_circ_0009035 inhibited CC cell proliferation, migration, invasion, and it enhanced apoptosis and radiosensitivity in vitro and weakened tumor growth in vivo. Mechanistically, hsa_circ_0009035 directly targeted miR-889-3p by binding to miR-889-3p, and hsa_circ_0009035 modulated HOXB7 expression through miR-889-3p. HOXB7 was a functional target of miR-889-3p in regulating CC progression and radioresistance in vitro, and hsa_circ_0009035 modulated CC progression and radioresistance in vitro by miR-889-3p. Our current study first identified hsa_circ_0009035 as an important regulator of CC progression and radioresistance at least in part through targeting the miR-889-3p/HOXB7 axis, highlighting its significance as a potential therapeutic target for CC treatment.

Abstract
Increasing evidence indicates that success of targeted therapies in the treatment of cancer is context-dependent and is influenced by a complex crosstalk between signaling pathways and between cell types in the tumor. The Fibroblast Growth Factor (FGF)/FGF receptor (FGFR) signaling axis highlights the importance of such context-dependent signaling in cancer. Aberrant FGFR signaling has been characterized in almost all cancer types, most commonly non-small cell lung cancer (NSCLC), breast cancer, glioblastoma, prostate cancer and gastrointestinal cancer. This occurs primarily through amplification and over-expression of FGFR1 and FGFR2 resulting in ligand-independent activation. Mutations and translocations of FGFR1-4 are also identified in cancer. Canonical FGF-FGFR signaling is tightly regulated by ligand-receptor combinations as well as direct interactions with the FGFR coreceptors heparan sulfate proteoglycans (HSPGs) and Klotho. Noncanonical FGFR signaling partners have been implicated in differential regulation of FGFR signaling. FGFR directly interacts with cell adhesion molecules (CAMs) and extracellular matrix (ECM) proteins, contributing to invasive and migratory properties of cancer cells, whereas interactions with other receptor tyrosine kinases (RTKs) regulate angiogenic, resistance to therapy, and metastatic potential of cancer cells. The diversity in FGFR signaling partners supports a role for FGFR signaling in cancer, independent of genetic aberration.

Abstract
Gynecologic malignancies, which include cancers of the cervix, ovary, uterus, vulva, vagina, and fallopian tube, are among the leading causes of female mortality worldwide, with the most prevalent being endometrial, ovarian, and cervical cancer. Gynecologic malignancies are complex, heterogeneous diseases, and despite extensive research efforts, the molecular mechanisms underlying their development and pathology remain largely unclear. Currently, mechanistic and therapeutic research in cancer is largely focused on protein targets that are encoded by about 1% of the human genome. Our current understanding of 99% of the genome, which includes noncoding RNA, is limited. The discovery of tens of thousands of noncoding RNAs (ncRNAs), possessing either structural or regulatory functions, has fundamentally altered our understanding of genetics, physiology, pathophysiology, and disease treatment as they relate to gynecologic malignancies. In recent years, it has become clear that ncRNAs are relatively stable, and can serve as biomarkers for cancer diagnosis and prognosis, as well as guide therapy choices. Here we discuss the role of small non-coding RNAs, i.e., microRNAs (miRs), P-Element induced wimpy testis interacting (PIWI) RNAs (piRNAs), and tRNA-derived small RNAs in gynecological malignancies, specifically focusing on ovarian, endometrial, and cervical cancer.

Abstract
Long non-coding RNAs (lncRNAs) are emerging regulators of cellular pathways, especially in cancer development. Among the lncRNAs, nuclear paraspeckle assembly transcript 1 (NEAT1) forms a scaffold for a nuclear body; the paraspeckle and aberrant expression of NEAT1 have been reported in breast and gynecologic cancers (ovarian, cervical, endometrial, and vulvar). Abundantly expressed NEAT1 in breast and gynecologic cancers generally contribute to tumor development by sponging its corresponding tumor-suppressive microRNAs or interacting with various regulatory proteins. The distinct expression of NEAT1 and its contribution to tumorigenic pathways make it a promising therapeutic target in breast and gynecologic cancers. Herein, we summarize the functions and molecular mechanisms of NEAT1 in human breast, ovarian, cervical, endometrial, and vulvar cancers. Furthermore, we emphasize its critical role in the formation of paraspeckle development and its functions. Conclusively, NEAT1 is a considerable biomarker with a bright prospect and can be therapeutically targeted to manage breast and gynecologic cancers.

Abstract
OBJECTIVE Esophageal squamous cell carcinoma (ESCC) is featured by early metastasis and late diagnosis. MicroRNA-301 (miR-301) is known to participate in diverse cancers. Nevertheless, effects of miR-301 on ESCC remain unexplored. Thus, we aim to explore the role of miR-301 in ESCC progression. METHODS Expression of miR-301 and phosphatase and tensin homologue (PTEN) in ESCC tissues and cell lines was assessed. Next, the screened cells were treated with altered miR-301 or PTEN oligonucleotide and plasmid, and then, the colony formation ability, cell viability, migration, invasion, cell cycle distribution and apoptosis of ESCC cells were assessed. Moreover, tumor growth and microvessel density (MVD) were also assessed, and the targeting relationship between miR-301 and PTEN was affirmed. RESULTS MiR-301 was upregulated, and PTEN was downregulated in ESCC tissues and cells. KYSE30 cells and Eca109 cells were selected for functional assays. In KYSE30 cells, inhibited miR-301 or overexpressed PTEN suppressed cell malignant behaviors, and silenced PTEN eliminated the impact of miR-301 inhibition on ESCC progression. In Eca109 cells, miR-301 overexpression or PTEN inhibition promoted cell malignant behaviors, and PTEN overexpression reversed the effects of miR-301 elevation on ESCC progression. The in vivo assay revealed that miR-301 inhibition or PTEN overexpression repressed ESCC tumor growth and MVD, and miR-301 elevation or PTEN reduction had contrary effects. Moreover, PTEN was targeted by miR-301. CONCLUSION Taken together, results in our study revealed that miR-301 affected cell growth, metastasis and angiogenesis via regulating PTEN expression in ESCC.

Qi H, Lu L, Wang L. Long Noncoding RNA ST7-AS1 Upregulates TRPM7 Expression by Sponging microRNA-543 to Promote Cervical Cancer Progression. Onco Targets Ther 2020; 13:7257-7269. [PMID: 32801754 PMCID: PMC7394585 DOI: 10.2147/ott.s253868] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 06/21/2020] [Indexed: 12/26/2022] Open
Abstract
Purpose ST7 antisense RNA 1 (ST7-AS1) is a long noncoding RNA that affects the progression of gastric cancer and laryngeal squamous cell carcinoma. Herein, ST7-AS1 expression was detected in cervical cancer tissues and cell lines. In addition, its biological roles in inducing the aggressive phenotype of cervical cancer and its associated mechanisms of action were illustrated. Patients and Methods ST7-AS1 expression in cervical cancer tissues and cell lines was detected using quantitative real-time polymerase chain reaction (qRT-PCR). Malignancy was determined using Cell Counting Kit-8 assay, flow cytometry, transwell migration and invasion assays, and xenograft experiments. Bioinformatics analysis was performed to predict the interaction between ST7-AS1 and microRNA-543 (miR-543). Luciferase reporter assay, RNA immunoprecipitation assay, Western blotting, qRT-PCR, and rescue experiments were performed to further identify the interactions among ST7-AS1, miR-543, and transient receptor potential melastatin 7 (TRPM7). Results ST7-AS1 was upregulated in cervical cancer tissues and cell lines. ST7-AS1 overexpression was correlated with a high International Federation of Gynecology and Obstetrics stage, frequent lymph node metastasis, deep cervical invasion, and short overall survival in patients with cervical cancer. ST7-AS1 inhibition hindered cervical cancer cell proliferation, migration, and invasion; ST7-AS1 downregulation resulted in marked cell apoptosis. Additionally, ST7-AS1 deficiency restricted cervical tumor growth in vivo. Mechanistically, ST7-AS1 functioned as competing endogenous RNA to increase TRPM7 expression by sponging miR-543. Intriguingly, rescue experiments revealed that miR-543 downregulation or TRPM7 overexpression abrogated the inhibitory actions of ST7-AS1 knockdown in the aggressive phenotype of cervical cancer cells. Conclusion The newly identified ST7-AS1/miR-543/TRPM7 axis promoted the oncogenicity of cervical cancer cells both in vitro and in vivo. Our study highlighted the importance of this novel axis in cervical cancer progression, suggesting that this pathway can serve as a promising therapeutic target for cervical cancer.

Abstract
The objective of this study was to determine the role of miR-3150b-3p in the cervical cancer (CC) progression. Real-time PCR and western blot analysis were conducted to test the expression of miR-3150b-3p, TNFRSF11a and p38 mitogen-activated protein kinase (MAPK) signaling pathway. The interaction between miR-3150b-3p and TNFRSF11a was verified by luciferase assay. Cell proliferation, migration and invasion were determined by CCK-8, wound healing and Transwell assays. In this study, we showed that miR-3150b-3p was significantly downregulated in CC cell lines. Additionally, miR-3150b-3p markedly attenuated the proliferation, migration and invasion of HeLa and SiHa cells. Moreover, we identified TNFRSF11a to be a novel target of miR-3150b-3p in CC cells. Enforced expression of TNFRSF11a abolished the antitumor effect of miR-3150b-3p. Besides, miR-3150b-3p was involved in the regulation of the p38 MAPK signaling pathway. In conclusion, our data suggested that miR-3150b-3p directly targets TNFRSF11a to inactivate the p38 MAPK signaling pathway, thus implicating miR-3150b-3p in the regulation of CC cell growth.

Long Noncoding RNA ZFPM2-AS1 Enhances the Malignancy of Cervical Cancer by Functioning as a Molecular Sponge of microRNA-511-3p and Consequently Increasing FGFR2 Expression. Cancer Manag Res 2020; 12:567-580. [PMID: 32158261 PMCID: PMC6986931 DOI: 10.2147/cmar.s238373] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 12/18/2019] [Indexed: 12/24/2022] Open
Abstract
Purpose A long noncoding RNA called ZFPM2 antisense RNA 1 (ZFPM2-AS1) has been verified as a key modulator in multiple human cancer types. Nonetheless, the expression and functions of ZFPM2-AS1 in cervical cancer remain poorly understood. Therefore, our purpose was to characterize the expression pattern, clinical value, and detailed roles of ZFPM2-AS1 in cervical cancer. Methods Reverse-transcription quantitative PCR was carried out to measure ZFPM2-AS1 expression in cervical cancer. A Cell Counting Kit-8 assay, flow cytometry, Transwell migration and invasion assays, and a tumor xenograft experiment were conducted to determine the influence of ZFPM2-AS1 on cervical cancer cell proliferation, apoptosis, migration, and invasion in vitro and on tumor growth in vivo, respectively. Results ZFPM2-AS1 was found to be aberrantly upregulated in cervical cancer, and its upregulation was associated with unfavorable values of clinical parameters. A ZFPM2-AS1 knockdown significantly reduced cervical cancer cell proliferation, migration, and invasion and increased apoptosis in vitro. The ZFPM2-AS1 knockdown decelerated tumor growth of cervical cancer cells in vivo. Molecular investigation indicated that ZFPM2-AS1 acts as a molecular sponge of microRNA-511-3p (miR-511-3p) in cervical cancer cells. Fibroblast growth factor receptor 2 (FGFR2) mRNA was validated as a direct target of miR-511-3p in cervical cancer, and its expression was positively modulated by ZFPM2-AS1. The effects of the ZFPM2-AS1 knockdown on malignant characteristics of cervical cancer cells were greatly attenuated by miR-511-3p inhibition. Conclusion ZFPM2-AS1 promotes cervical cancer progression through upregulation of miR-511-3p–FGFR2 axis output, thereby pointing to possible diagnostics and therapeutics based on the ZFPM2-AS1–miR-511-3p–FGFR2 pathway.
