Abstract Cervical cancer is a common malignancy of the female reproductive system. Long noncoding RNAs (lncRNAs) have been reported to modulate tumor progression in multiple cancers. The lncRNA antisense noncoding RNA in the INK4 locus (ANRIL) has been identified as an oncogenic molecular target in several tumors; however, the function and underlying mechanism involved in cervical cancer oncogenesis are still unclear. In the present study, RT-PCR showed that ANRIL expression was significantly upregulated in cervical cancer tumors and cell lines. Nevertheless, ANRIL knockdown transfected with interference oligonucleotide inhibited the proliferation activity and invasive ability, and promoted More >

Abstract Recent evidence suggests that dysregulation of microRNAs is associated with the development of multiple malignancies. miR-186 has been reported as a critical cancer regulator in several types of cancers. However, its functional significance and molecular mechanism underlying renal cell carcinoma (RCC) remain unknown. In this study, our results showed that miR-186 expression was dramatically downregulated in RCC tissues and cell lines compared to that in adjacent normal tissues and cell lines. Overexpression of miR-186 significantly inhibited cell growth, colony formation, and cell invasion; caused cell cycle arrest at the G₀/G₁ phase; and induced cell apoptosis as… More >

Abstract Deregulation of miR-186 and Twist1 has been identified to be involved in the progression of multiple cancers. However, the detailed molecular mechanisms underlying miR-186-involved cholangiocarcinoma (CCA) are still unknown. In this study, we found that miR-186 was downregulated in CCA tissues and cell lines, and negatively correlated with the expression of Twist1 protein. In vitro assays demonstrated that miR-186 mimics repressed cell proliferation, in vivo tumor formation, and caused cell cycle arrest. miR-186 mimics also inhibited the migration and invasion of CCLP1 and SG-231 cells. Mechanistically, the 3′-untranslated region (3′-UTR) of Twist1 mRNA is a More >

Abstract The present study aimed to investigate the effect of miR-186 on proliferation, migration, invasion, and epithelial–mesenchymal transition (EMT) of hepatocellular carcinoma (HCC). In this work, miR-186 was downregulated in HCC tissues and cells, and low miR-186 level helped predict the occurrence of vascular invasion and poor prognosis in patients with HCC. miR-186 overexpression inhibited cell proliferation and tumor growth in nude mice, repressed migration and invasion abilities, and enhanced apoptosis in HCC cells. miR-186 also retarded progression of EMT. miR-186 directly bound to the 3 -untranslated regions of cyclin-dependent kinase 6 (CDK6) to inhibit its More >
