Abstract
- Objectives Emerging studies have demonstrated that micro RNAs (mi RNAs) play crucial roles in carcinogenesis of many developing human tumours. However, the functions and mechanisms of miR-297 in lung cancer have, up to now, been largely undefined. Materials and methods Here, miR-297 expression was measured in lung adenocarcinoma tissues and cell lines, using qRT- PCR. Lung adenocarcinoma cell line was treated with an miR-297 mimic. MTT and colony analysis were performed to detect cell proliferation and colony formation. The direct target gene of miR-297 was assessed by qRT- PCR, Western blotting and luciferase assays. Results We demonstrated that miR-297 expression was upregulated in lung adenocarcinomas compared to adjacent normal tissues. Expression of miR-297 was also upregulated in tested lung adenocarcinoma cell lines. Ectopic expression of miR-297 enhanced lung adenocarcinoma cell proliferation and colony formation. Furthermore, overexpression of miR-297 promoted cell migration and invasion. In addition, we identified Glypican-5 ( GPC5) as a direct target gene of miR-297 in lung adenocarcinoma cells. Expression of GPC5 was downregulated in both lung adenocarcinoma tissues and cell lines. Moreover, expression of GPC5 was inversely associated with expression of miR-297 in lung adenocarcinoma tissues. Conclusions These results suggest that miR-297 acted as an oncogenic mi RNA, partly by targeting GPC5, adenocarcinoma of the lung. [ABSTRACT FROM AUTHOR]
