肿瘤抑制因子p16 INK 4a的表达在衰老和复制性衰老过程中增加。在这里,我们报告了microRNA miR-24抑制人二倍体成纤维细胞和宫颈癌细胞中p16的表达。随着复制性衰老,p16表达增加与miR-24水平降低相关,miR-24是一种预测与p16 mRNA编码区和3′-非翻译区相关的microRNA。异位miR-24过表达降低p16蛋白水平,但不降低p16 mRNA水平。相反,反义(AS)-miR-24的引入阻断了miR-24的表达,并显著增强了p16蛋白水平、p16翻译和携带miR-24靶识别位点的EGFP-p16报告基因的产生。总之,我们的研究结果表明,miR-24抑制p16翻译的起始和延伸阶段。
Expression of the tumor suppressor p16INK4a increases during aging and replicative senescence. Here, we report that the microRNA miR-24 suppresses p16 expression in human diploid fibroblasts and cervical carcinoma cells. Increased p16 expression with replicative senescence was associated with decreased levels of miR-24, a microRNA that was predicted to associate with the p16 mRNA coding and 3′-untranslated regions. Ectopic miR-24 overexpression reduced p16 protein but not p16 mRNA levels. Conversely, introduction of antisense (AS)-miR-24 blocked miR-24 expression and markedly enhanced p16 protein levels, p16 translation, and the production of EGFP-p16 reporter bearing the miR-24 target recognition sites. Together, our results suggest that miR-24 represses the initiation and elongation phases of p16 translation.
