Dual-luciferase reporter assays verified that glioma-associated oncogene 1 (GLI1) can be a book molecular focus on of miR-584. The overexpression of miR-584 inhibited the manifestation of GLI1, decreased cell proliferation, invasion and migration, and induced apoptosis in HeLa cells. Nevertheless, the silencing of miR-584 in CaSki cells created the opposite results. In addition, the overexpression of GLI1 in HeLa-cells overexpressing miR-584 reversed the miR-584-induced inhibitory effect markedly. Flow cytometry outcomes demonstrated that miR-584 improved cisplatin level of sensitivity by advertising chemotherapy-induced apoptosis. Consequently, miR-584 acted like a tumor suppressor miRNA and may be a book focus on Arranon inhibitor gene for potential cervical cancer remedies. luciferase activity. Bioinformatics prediction To research the possible target genes of miR-584, the online prediction system, TargetScan 7.1 software (http://www.targetscan.org), was used. Statistical analysis Results are presented as the mean SEM. Significance was established using the SPSS 13.0 software (SPSS, Inc). Data were analyzed using a Student’s t-test or one-way analysis of variance followed by Tukey’s Honest Significant Difference test. Pearson’s correlation analysis was used to analyze the correlation between miR-584 and GLI1 mRNA expression. P 0.05 was considered to indicate a statistically significant difference. Results Expression of miR-584 is downregulated in human cervical cancer tissues and cells To explore the role of miR-584 in cervical cancer, miR-584 expression was first detected in 30 pairs of cervical cancer tissues and adjacent normal tissues by RT-qPCR. RT-qPCR results illustrated that the expression of miR-584 was significantly downregulated in tumor Arranon inhibitor tissues compared with normal tissues (Fig. 1A). In addition, the expression levels of miR-584 were analyzed in immortalized normal cervical cell line Ect1/E6E7 and four types of cervical cancer cells (C33A, Rabbit polyclonal to ZNF624.Zinc-finger proteins contain DNA-binding domains and have a wide variety of functions, mostof which encompass some form of transcriptional activation or repression. The majority ofzinc-finger proteins contain a Krppel-type DNA binding domain and a KRAB domain, which isthought to interact with KAP1, thereby recruiting histone modifying proteins. Zinc finger protein624 (ZNF624) is a 739 amino acid member of the Krppel C2H2-type zinc-finger protein family.Localized to the nucleus, ZNF624 contains 21 C2H2-type zinc fingers through which it is thought tobe involved in DNA-binding and transcriptional regulation SiHa, HeL and CaSki) using RT-qPCR. The results showed that the expression of miR-584 in cervical cancer cell lines was significantly reduced compared with Ect1/E6E7 cells (Fig. 1B). Open in a separate window Figure 1. Expression of miR-584 is downregulated in human cervical cancer tissues and cells. (A) RT-qPCR was used to detect the expression of miR-584 in 30 pairs of human cervical cancer tissues and normal tissues.

RT-qPCR, reverse transcription-quantitative PCR; miR, microRNA. miR-584 inhibits cervical cancer cell proliferation and metastasis To study the effects of miR-584 in cervical cancer progression, miR-584 overexpression or inhibition assays were performed in HeLa and CaSki cells, which contained Arranon inhibitor the lowest or highest endogenous miR-584 expression levels, respectively. The results of the RT-qPCR assay illustrated that miR-584 expression was significantly increased in HeLa cells and significantly downregulated in CaSki cells when compared with controls (Fig. 2A). The results of the CCK-8 (Fig. 2B) and colony formation assay (Fig. 2C) illustrated that the proliferation of HeLa cells transfected with miR-584 mimics was markedly inhibited compared with the miR-NC group. Conversely, a significant increase in cell proliferation was observed in CaSki cells transfected with miR-584 inhibitors when compared with controls (Fig. 2C and D). Furthermore, the Transwell assay illustrated that the migration and invasion ability of the HeLa cells transfected with miR-584 mimics markedly decreased set alongside the Arranon inhibitor miR-NC group, as the silencing of miR-584 improved the migration as well as the invasion capacity for the CaSki cells (Fig. 2E and F).
