Abstract The aim of the present study was to investigate the roles of microRNA-152 (miR-152) in the initiation and progression of breast cancer. The expression level of miR-152 was detected in human breast cancer tissue and a panel of human breast cancer cell lines using qRT-PCR. Results found that miR-152 expression was significantly downregulated in breast cancer tissue samples compared to adjacent noncancerous tissues as well as in breast cancer cell lines. Overexpression of miR-152 significantly suppressed breast cancer cell proliferation, migration, and invasion. Luciferase reporter assay results found that ROCK1 is a direct and functional More >

Abstract MicroRNAs (miRs) have been demonstrated to be involved in the development and progression of osteosarcoma (OS), but the molecular mechanism still remains to be fully investigated. The present study investigated the function of miR-148a in OS, as well as its underlying mechanism. Our data showed that miR-148a was significantly downregulated in OS tissues compared to their matched adjacent normal tissues, and also in OS cell lines compared to normal human osteoblast cells. Low expression of miR-148a was significantly associated with tumor progression and a poor prognosis for OS patients. Rho-associated coiled-coil kinase 1 (ROCK1) was… More >

Abstract MicroRNAs (miRNAs) are small conserved RNAs regulating specific target genes in posttranscriptional levels. They have been involved in multiple processes of tumor progression, including cell proliferation. miR-214-5p (also miR-214*) is a newly identified miRNA, and its functions are largely unknown. In this study, we explore the role of miR-214-5p in the proliferation and invasion of human osteosarcoma (OS) cells. The results showed that miR-214-5p was sharply reduced in OS tissues and cell lines, compared with normal tissues and cell lines. In addition, the miR-214-5p mimic greatly increased the miR-214-5p level and significantly decreased the proliferation More >
