Abstract

MicroRNAs (miRNAs) play an important role in the development of various cancers, including cervical cancer (CC). The dysregulation of miRNA expression is associated with oncogenic transformation and miRNA often act as tumor suppressors. In this study, we aimed to analyze the effect on and mechanism of miR-139-3p in the progression of CC. The result of real-time PCR showed that miR-139-3p was down-regulated in CC tissues and cell lines. Overexpression of miR-139-3p significantly suppressed HeLa cell proliferation, migration and invasion and induced cell apoptosis. Bioinformatics analysis and luciferase reporter gene assay confirmed that NOB1 was targeted by miR-139-3p at the 3'-untranslated region (3'UTR) of its mRNA sequence. Furthermore, overexpression of NOB1 counteracted the effects of miR-139-3p suppression. Our results suggest that miR-139-3p may act as a tumor suppressor that can inhibit CC cell proliferation, migration and invasion and induce cell apoptosis through down-regulation of NOB1 expression. Taken together, this study provides a novel potential therapeutic strategy for the treatment of CC.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.
