e14519 Background: Transcriptional factor FOXO1and PAX3 has been reported to play an imported role in human cancer, but the role in cervical cancer has not yet been clarified. Here, we evaluated the functional role of FOXO1 with cervical cancer cells and the expression together with clinical significance of FOXO1 and PAX3 among cervical lesions was investigated. Methods: In vitro assessment of cell functions by cell viably assay, cell migration and invasion assay was evaluated using FOXO1 knockdown cervical cancer cell lines. Immuno-histochemical (IHC) staining analyses of FOXO1 and PAX3 were performed with tissue microarray (TMA) consisting of 209 cervical cancers, 366 high grade cervical intraepithelial neoplasias (CIN), 130 low grade CIN and 328 matched nonadjacent normal cervical epithelial tissues. The clinical significance was investigated by comparing the data with various clinicopathologic characteristics, including survival in cervical cancer. Results: In vitro result revealed that knockdown of FOXO1 was associated decreased cell viability ( p< 0.001), migration ( p< 0.001) and invasion ( p< 0.05) supporting the oncogenic role of FOXO1 in cervical cancer. FOXO1 and PAX3 expression was significantly higher in CIN (both p< 0.001) and cancer tissue (both p< 0.001) than in normal tissue. FOXO1 expression showed significant correlation with PAX3 (Spearman’s rho = 0.377, p< 0.001) in a cervical cancer. Multivariate analysis indicates that FOXO1 expression (hazard ratio = 4.01 [95% CI, 1.22–13.10], p= 0.021) and advanced FIGO stage (hazard ratio = 3.89 [95% CI, 1.35–11.19], p= 0.012) were independent prognostic factor on overall survival. Conclusions: This study reveals the association between FOXO1 and PAX3 expression with clinicopathologic variables, including survival of cervical cancer patients. Our results not only suggest the promising potential of FOXO1 as a prognostic and survival marker, but also warrant further studies on a possible link between the biological function of FOXO1 and the pathogenesis of cervical cancer.

Objectives: MicroRNAs were revealed as biomarkers for early detection or prognosis predictors of cancer and were involved in the progression of cancer. The present study investigated the expression pattern, potential clinical, and functional role of miR-885-5p in cervical cancer. Design: A total of 115 pairs of cervical cancer tissue specimens and adjacent non-tumor paracancerous tissue specimens were collected from the cervical cancer patients who underwent surgical resection or biopsy without preoperative systemic therapy at Maternity and Child Health Care of Zaozhuang from 2012 to 2014. Participants/Materials, Setting, Methods: The expression levels of miR-885-5p in cervical cancer were measured using the qRT-PCR assay. A follow-up study was conducted and the Kaplan-Meier method with log-rank test was used to analyze the potential clinical significance of miR-885-5p in cervical cancer. The functional experiments including CCK-8, Transwell migration, and invasion assays were used to investigate the biological function of miR-885-5p in cervical cancer cells. Results: miR-885-5p expression was decreased in tumor tissues and tumor cell lines compared to normal control. Low expression of miR-885-5p was related to lymph node metastasis, late FIGO stage, and shorter overall survival outcome. Ascending expression of miR-885-5p inhibited the proliferative, migratory, and invasive abilities of cervical cancer cells, while downregulation of miR-885-5p promoted these cellular abilities of cervical cancer cells in vitro. Limitations: The patient population size was limited, thus the clinical significance of miR-885-5p requires further verification. Secondly, the precise mechanism of miR-885-5p in cervical cancer still exclusive. In future studies, a larger sample size will be required to confirm the prognostic value of miR-885-5p in cervical cancer, and the possible targets, as well as the detailed mechanism of miR-885-5p, will be investigated. Conclusions: miR-885-5p expression was decreased in cervical cancer and downregulation of miR-885-5p promoted the progression of cervical cancer cells. miR-885-5p may be an independent prognostic predictor and therapeutic target for treating cervical cancer.

Objective To inquiry about mechanism of miR-100-5p/CDC25A axis in breast carcinoma (BC), thus offering a new direction for BC targeted treatment. Methods qRT-PCR was employed to explore miR-100-5p and CDC25A mRNA levels. Western blot was employed for detecting protein expression of CDC25A. Targeting relationship of miR-100-5p and CDC25A was verified by dual-luciferase assay. In vitro experiments were used for assessment of cell functions. Results In BC tissue and cells, miR-100-5p was significantly lowly expressed (P < 0.05) while CDC25A was highly expressed. Besides, miR-100-5p downregulated CDC25A level. miR-100-5p had a marked influence on the prognosis of patients. The forced miR-100-5p expression hindered BC cell proliferation, migration and invasion, and facilitated cell apoptosis. Upregulated miR-100-5p weakened promotion of CDC25A on BC cell growth. Conclusion Together, these findings unveiled that CDC25A may be a key target of miR-100-5p that mediated progression of BC cells. Hence, miR-100-5p overexpression or CDC25A suppression may contribute to BC diagnosis.

SIRT1 (silent information regulator 1), a NAD+-dependent III class histone deacetylase, plays crucial roles in cell proliferation, apoptosis, senescence, metabolism, and stress responses. Nevertheless, the role of SIRT1 in tumorigenesis remains unclear. In the present study, we measured expression levels of SIRT1 and HPV16 E7 protein in cervical cancer tissue and calculated their correlations. We measured the effect of silencing SIRT1 on the proliferation, migration, invasion, and apoptosis in human cervical cancer SiHa cells. Immunohistochemistry results revealed that the expression of SIRT1 was upregulated with progression from CINII-III to cervical cancer, but was not expressed in normal cervical tissues and CINI. There was a positive correlation between SIRT1 expression and HPV16 E7 expression in cervical cancer tissues, and silencing of HPV16 E7 downregulated the expression of SIRT1. Depletion of SIRT1 significantly downregulated SIRT1 expression, and inhibited proliferation, migration, and invasion of SiHa cells, inducing apoptosis. Taken together, the data suggest that SIRT1 promotes cervical cancer carcinogenesis. SIRT1 inhibition is a potential treatment strategy for cervical cancer.

microRNA-23a (miR-23a) is one of the most extensively studied miRNAs in different types of human cancer, and plays various roles in the initiation, progression, and treatment of tumors. Here, we comprehensively summarize and discuss the recent findings about the role of miR-23a in cancer. The differential expression of tissue miR-23a was reported, potentially indicating cancer stages, angiogenesis, and metastasis. miR-23a in human biofluid, such as plasma and salivary fluid, may be a sensitive and specific marker for early diagnosis of cancer. Tissue and circulating miR-23a serves as a prognostic factor for cancer patient survival, as well as a predictive factor for response to anti-tumor treatment. The direct and indirect regulation of miR-23a on multiple gene expression and signaling transduction mediates carcinogenesis, tumor proliferation, survival, cell migration and invasion, as well as the response to anti-tumor treatment. Tumor cell-derived miR-23a regulates the microenvironment of human cancer through manipulating both immune function and tumor vascular development. Several transcriptional and epigenetic factors may contribute to the dysregulation of miR-23a in cancer. This evidence highlights the essential role of miR-23a in the application of cancer diagnosis, prognosis, and treatment.

Cervical cancer is one of the dominant gynecological disorders which has poor prognosis and often diagnosed at advanced stages where it becomes nearly impossible to effectively manage this disorder. MicroRNA-300 (miR-300) has dual role in human tumorogenesis. However, characterization of its regulatory action has not been made in cervical cancer. The molecular role of miR-300 in cervical cancer was thus explored in the present study with prime focus on elucidating its mechanism of action. The results showed significant (P < 0.05) downregulation of miR-300 in cervical cancer. Overexpression of miR-300 in cervical cancer cells inhibited their proliferation in vitro by inducing apoptosis. Cervical cancer cells overexpressing miR-300 also showed decreased rates of migration and invasion. G protein-coupled receptor 34 (GPR34) was found to be the functional regulatory target of miR-300 in cervical cancer. GPR34 was found to be significantly (P < 0.05) overexpressed in cervical cancer tissues and cell lines. Silencing of GPR34 inhibited the growth of the cervical cancer cells. However, overexpression of GPR34 could prevent the tumor-suppressive effects of miR-300 on cervical cancer cells. Collectively, the results of the current study are indicative of the tumor-suppressive regulatory role of miR-300 in cervical cancer and suggestive of the potential therapeutic value of miR-300/GPR34 molecular axis.

AbstractGastric carcinoma proliferation enhancing transcript 1 (GHET1) has been suggested to serve as a promising oncogenic lncRNA in various types of human cancer. However, the role of GHET1 remained unknown in cervical cancer. In our study, we found GHET1 expression was markedly elevated in cervical cancer tissue specimens and cell lines compared with adjacent normal cervical tissue specimens and human normal cervical cell line, respectively. Then, we found high expression of GHET1 is a useful biomarker to discriminate cervical cancer tissues from non-tumorous tissues, and associated with advanced clinical stage, lymph node metastasis, distant metastasis and poor histological grade in cervical cancer patients. The survival analysis showed high GHET1 expression was an independent unfavorable prognostic factor in cervical cancer patients. Knockdown of GHET1 expression markedly inhibits cervical cancer cell proliferation, migration, and invasion. The loss-of-function study indicated knockdown of GHET1 expression markedly inhibits cervical cancer cell proliferation, migration, and invasion. In conclusion, GHET1 acts as an oncogenic lncRNA in cervical cancer.

SWI/SNF complex subunit Actin-like protein 6A (ACTL6A) has been regarded as an oncogene, regulating the proliferation, migration and invasion of cancer cells. However, the expression pattern and biological role of ACTL6A in cervical cancer have not been reported. In this study, the mRNA expression and protein level of ACTL6A in cervical cancer samples were determined by public database and immunohistochemical (IHC) analysis. The effects of ACTL6A on cervical cancer cells were investigated via MTT, colony-formation assay, tumor xenografts and flow cytometry. Gene set enrichment analysis (GSEA) was used to explore the potential mechanism of ACTL6A in regulating tumorigenesis of cervical cancer. The results revealed that ACTL6A was markedly upregulated in cervical cancer tissues. Silencing ACTL6A expression resulted in decreased cervical cancer cell proliferation, colony formation and tumorigenesis in vitro and in vivo. Furthermore, we demonstrated that knockdown of ACTL6A induced cell cycle arrest at G1 phase, ACTL6A-mediated proliferation and cell cycle progression were c-Myc dependent. Our study provides the role of ACTL6A in cervical oncogenesis and reveals a potential target for therapeutic intervention in this cancer type.

Abstract Cervical cancer (CC) is a huge threat to the health of women worldwide. Long non-coding RNA plasmacytoma variant translocation 1 gene (PVT1) was proved to be associated with the development of diverse human cancers, including CC. Nevertheless, the exact mechanism of PVT1 in CC progression remains unclear. Levels of PVT1, microRNA-503 (miR-503), and ADP ribosylation factor-like protein 2 (ARL2) were measured by quantitative reverse transcription-polymerase chain reaction or western blot assay. 3-(4,5)-Dimethylthiazole-2-y1)-2,5-biphenyl tetrazolium bromide (MTT) and flow cytometry were used to examine cell viability and apoptosis, respectively. For migration and invasion detection, transwell assay was performed. The interaction between miR-503 and PVT1 or ARL2 was shown by dual luciferase reporter assay. A nude mouse model was constructed to clarify the role of PVT1 in vivo. PVT1 and ARL2 expressions were increased, whereas miR-503 expression was decreased in CC tissues and cells. PVT1 was a sponge of miR-503, and miR-503 targeted ARL2. PVT1 knockdown suppressed proliferation, migration, and invasion of CC cells, which could be largely reverted by miR-503 inhibitor. In addition, upregulated ARL2 could attenuate si-PVT1-mediated anti-proliferation and anti-metastasis effects on CC cells. Silenced PVT1 also inhibited CC tumor growth in vivo. PVT1 knockdown exerted tumor suppressor role in CC progression via the miR-503/ARL2 axis, at least in part.

<b><i>Background:</i></b> 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. <b><i>Methods:</i></b> 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. <b><i>Results:</i></b> 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. <b><i>Conclusion:</i></b> 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 Background Cervical cancer is a type of the most common gynecology tumor in women of the whole world. Accumulating data have shown that icariin (ICA), a natural compound, has anti-cancer activity in different cancers, including cervical cancer. The study aimed to reveal the antitumor effects and the possible underlying mechanism of ICA in U14 tumor-bearing mice and SiHa cells. Methods The antitumor effects of ICA were investigated in vivo and in vitro. The expression of TLR4/MyD88/NF-κB and Wnt/β-catenin signaling pathways were evaluated. Results We found that ICA significantly suppressed tumor tissue growth and SiHa cells viability in a dose-dependent manner. Also, ICA enhanced the anti-tumor humoral immunity in vivo. Moreover, ICA significantly improved the composition of the microbiota in mice models. Additionally, the results clarified that ICA significantly inhibited the migration, invasion capacity, and expression levels of TGF-β1, TNF-α, IL-6, IL-17A, IL-10 in SiHa cells. Meanwhile, ICA was revealed to promote the apoptosis of cervical cancer cells by down-regulating Ki67, survivin, Bcl-2, c-Myc, and up-regulating P16, P53, Bax levels in vivo and in vitro. For the part of mechanism exploration, we showed that ICA inhibits the inflammation, proliferation, migration, and invasion, as well as promotes apoptosis and immunity in cervical cancer through impairment of TLR4/MyD88/NF-κB and Wnt/β-catenin pathways. Conclusions Taken together, ICA could be a potential supplementary agent for cervical cancer treatment.
