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.

The expression of anti-silencing function 1B (ASF1B) in cervical cancer patients were previously reported, indicating its implications as a new candidate gene related to the development of cervical lesions and cancer. In this study, we investigated the possible role of ASF1B in cervical carcinogenesis. ASF1B messenger RNA and protein expression was assessed in five cervical cancer cell line models, Hela, C-33A, SiHa, CaSKi, HCC-94 and normal cervical epithelium cell Ect. Gene silencing approach was employed to investigate the potential role of ASF1B in cellular growth, proliferation, colony-forming ability, migration and invasion in Hela cells. Our data indicated that ASF1B was expressed in all cervical cancer cells at the gene and protein level. Gene silencing of ASF1B caused significant inhibition in cellular proliferation, colony-forming ability, migration and invasion ability, and promote apoptosis of Hela cells. However, the biological effects of ASF1B silencing on Hela cells were reversing after down-regulating recombinant chromatin assembly factor 1, subunit B (CHAF1B). Collectively, our findings concluded that silencing ASF1B inhibits proliferation and migration of Hela cells and promotes apoptosis by down-regulating CHAF1B.

Purpose: The current study was intended to research the functional role and regulatory mechanism of microRNA-96-5p in the progression of cervical cancer. Methods: MicroRNA-96-5p expression in cervical cancer tissues was assessed by quantitative real-time polymerase chain reaction. The association between microRNA-96-5p expression and clinicopathological features of patients with cervical cancer was analyzed. MTT, flow cytometry, wound healing, and transwell assay were performed to evaluate the viability, apoptosis, migration, and invasion of Hela and SiHa cells. Targetscan, dual-luciferase reporter gene assay, and RNA pull-down analysis were constructed to evaluate the target relationship between microRNA-96-5p and secreted frizzled-related protein 4. Results: MicroRNA-96-5p was overexpressed in cervical cancer tissues, and microRNA-96-5p expression was markedly associated with the clinical stage and lymph node metastasis of patients with cervical cancer. Overexpressed microRNA-96-5p facilitated the viability, migration, invasion, and inhibited the apoptosis of Hela and SiHa cells, whereas suppression of microRNA-96-5p exerted the opposite trend. Secreted frizzled-related protein 4 was proved to be a target of microRNA-96-5p. Silencing of secreted frizzled-related protein 4 eliminated the anti-tumor effect of microRNA-96-5p on cervical cancer cells. Conclusions: MicroRNA-96-5p facilitated the viability, migration, and invasion and inhibited the apoptosis of cervical cancer cells via negatively regulating secreted frizzled-related protein 4.

Abstract Background X inactivation-specific transcript (XIST) is the long non-coding RNA (lncRNA) related to cancer, which is involved in the development and progression of various types of tumor. However, up to now, the exact role and molecular mechanism of XIST in the progression of ovarian cancer are not clear. We studied the function of XIST in ovarian cancer cells and clinical tumor specimens. Methods RT-qPCR was performed to detect the expression levels of miR-335 and BCL2L2 in ovarian cancer cells and tissues. MTT and transwell assays were carried out to detect cell proliferation, migration, and invasion abilities. Western blot was performed to analyze the expression level of BCL2L2. The interaction between miR-335 and XIST/BCL2L2 was confirmed using a luciferase reporter assay. Results The inhibition of XIST can inhibit the proliferation invasion and migration of human ovarian cancer cells. In addition, the miR-335/BCL2L2 axis was involved in the functions of XIST in ovarian cancer cells. These results suggested that XIST could regulate tumor proliferation and invasion and migration via modulating miR-335/BCL2L2. Conclusion XIST might be a carcinogenic lncRNA in ovarian cancer by regulating miR-335, and it can serve as a therapeutic target in human ovarian cancer.

Purpose: To investigate the anticancer effects of swertiamarin against taxol- resistant human cervical cancer cells.Method: Cell viability was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5–diphenyl tetrazolium bromide (MTT) assay while colony survival was evaluated by clonogenic assay. Apoptotic cell death was assessed by AO/ETBR staining and western blotting techniques. The levels of reactive oxygen species (ROS) were measured using 2,7, dicholoro dihydrofluoresceindiacetate (H2DCFDA) staining.Cell migration and invasion were monitored with Transwell chamber assay. Western blotting assay was used to determine the expression levels of proteins of the MEK/ERK signaling pathway.Results: Swertiamarin induced dose- and time-dependent inhibition of proliferation of HeLa cervical cancer cells (p < 0.05). It also suppressed the colony formation potential of HeLa cells, and induced various structural modifications in HeLa cells. Swertiamarin exposure resulted in the formation of earlyapoptotic, late-apoptotic and necrotic cells, and significant modulation of apoptosis-allied proteins. It was observed that the migration and invasion of HeLa cells were potentially suppressed in dose-reliant fashion by swertiamarin. Western blotting results showed that the expressions of p-MEK and p-ERK were markedly reduced, while those of MEK and ERK were unaffected (p < 0.05).Conclusion: Swertiamarin exerts in vitro anticancer activity against cervical cancer cells (HeLa). Thus, it is promising for use in cervical cancer chemotherapy. However, there is need for confirmation of these findings through further in vivo and in vitro investigations.

Purpose: To identify the role of baicalein in human cervical cancer and to determine whether baicalein treatment affects hedgehog/Gli signaling pathway. Methods: Cell proliferation was evaluated by MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and colony formation assays. Cell death rate was assessed by PI-staining and FACS assay. Furthermore, cell invasion was assessed by Transwell assay while the levels of the key proteins were measured by western blotting analysis. Results: Baicalein suppressed the viability and proliferation of HeLa cells. The colony formation ability and relative migration rate were significantly decreased in the HeLa cells treated with 50 μM baicalein. Furthermore, the levels of Shh, Gli1, MMP-9, and VEGF declined significantly in baicalein-treated cells. Conclusion: The results demonstrate that baicalein inhibits the growth and invasiveness of cervical cancer cells partly by suppressing the activation of hedgehog/Gli signaling pathway in a concentrationdependent manner.

Background: Osteosarcoma (OS) is a prevalent primary bone malignancy and its distal metastasis remains the main cause of mortality in OS patients. MicroRNAs (miRNAs) play critical roles during cancer metastasis. Objective: Thus, elucidating the role of miRNA dysregulation in OS metastasis may provide novel therapeutic targets. Methods: The previous study found a low miR-134 expression level in the OS specimens compared with paracancer tissues. Overexpression of miR-134 stable cell lines was established. Cell viability assay, cell invasion and migration assay and apoptosis assay were performed to evaluate the role of miR-134 in OS in vitro. Results: We found that miR-134 overexpression inhibits cell proliferation, migration and invasion, and induces cell apoptosis in both MG63 and Saos-2 cell lines. Mechanistically, miR-134 targets the 3'-UTR of VEGFA and MYCN mRNA to silence its translation, which was confirmed by luciferase-reporter assay. The real-time PCR analysis illustrated that miR-134 overexpression decreases VEGFA and MYCN mRNA levels. Additionally, the overexpression of VEGFA or MYCN can partly attenuate the effects of miR-134 on OS cell migration and viability. Furthermore, the overexpression of miR-134 dramatically inhibits tumor growth in the human OS cell line xenograft mouse model in vivo. Moreover, bioinformatic and luciferase assays indicate that the expression of miR-134 is regulated by Interferon Regulatory Factor (IRF1), which binds to its promoter and activates miR-134 expression. Conclusion: Our study demonstrates that IRF1 is a key player in the transcriptional control of miR-134, and it inhibits cell proliferation, invasion and migration in vitro and in vivo via targeting VEGFA and MYCN.
