MicroRNA-224靶向CNNM1抑制前列腺癌血管生成的实验研究
miR-224 inhibits angiogenesis of prostate cancer by targeting cyclin protein M1
摘要
Abstract
Objective To investigate the impacts of miR-224 on biochemical recurrence and angiogenesis of prostate cancer. Methods Bioinformatics analysis and luciferase reporter assay were performed to predict the gene that can be directly inhibited by miR-224. Taylor database was used for confirming the expressions of CNNM1 and miR-224, and their correlations with biochemical recurrence of prostate cancer. Finally, the impacts of CNNM1 and miR-224 on angiogenesis of prostate cancer were explored by PC3 cell in vitro and in vivo. Results CNNM1 was directly regulated by miR-224, and their expression levels were negatively correlated in prostate cancer tissue ( r=-0.378, P<0.05). miR-224 was negatively correlated to, while CNNM1 was positively correlated to biochemical recurrence of prostate cancer (P<0.05). The expressions of CNNM1 and CD31 decreased in the PC3 cells overexpressing miR-224 (P<0.05). However, CNNM1 enhanced the expression level of CD31 (P<0.05). The immunochemical staining of the transplantation tumor in the nude mice displayed that miR-224 overexpression could suppress angiogenesis in the prostate cancer tissue. Conclusions miR-224 suppresses angiogenesis and biochemical recurrence of prostate cancer by targeting CNNM1.关键词
