miR-21對(duì)ADAMTS-1的調(diào)節(jié)在肺纖維化體內(nèi)外實(shí)驗(yàn)中的研究
[Abstract]:Aim: to investigate the regulatory effect of mi R-21 on the expression of ADAMTS-1 in pulmonary fibrosis model. Methods: (1) establish bleomycin induced pulmonary fibrosis model in mice and establish pulmonary fibrosis model in vitro. The expression of mi R-21 was detected by Q RT-PCR. The expression of ADAMTS-1 protein was detected by Western blot. (2) the expression of ADAMTS-1 protein was detected by transfection of mi R-21 analogue (mimics) and (inhibitors) to NIH3T3 cell, Westem blot in vitro. Results: (1) compared with the blank control group, the expression of mi R-21 in lung tissue of mice treated with bleomycin was upregulated significantly at three time points after treatment with bleomycin. The expression of ADAMTS-1 protein was down-regulated (P0.01). (2). In the model of pulmonary fibrosis in vitro, the expression of ADAMTS-1 protein was down-regulated in NIH3T3 cells stimulated by 5 渭 g / L TGF- 尾 1. The expression of mi R-21 was significantly up-regulated (P0.01). (3). After transfection of mi R-21 analogues and inhibitors into NIH3T3 cells, the results showed that the expression of ADAMTS-1 in NIH3T3 cells was down-regulated after high expression of mi R-21, and vice versa. Conclusion: (1) the expression of mi R-21 increased and the expression of ADAMTS-1 protein decreased in vitro and in vivo. (2) mi R-21 negatively regulated the expression of ADAMTS-1.
