MicroRNA是一类小的非编码RNA,其通过靶向mRNA进行翻译抑制或降解而发挥关键基因调节剂的作用。在这项研究中,我们发现miR-128在胶质瘤中的表达水平降低,并确定p70 S6 K1为miR-128的新的直接靶点。过表达miR-128可抑制p70 S6 K1及其下游信号分子如HIF-1和VEGF的表达,并减弱细胞增殖、肿瘤生长和血管生成。p70 S6 K1的强制表达可以部分挽救miR-128在细胞中的抑制作用。这些研究结果将有助于阐明miR-128通过miR-128/p70 S6 K1轴调控胶质瘤血管生成的作用和机制,miR-128有可能成为胶质瘤潜在的治疗靶点。
MicroRNAs are a class of small noncoding RNAs that function as critical gene regulators through targeting mRNAs for translational repression or degradation. In this study, we showed that miR-128 expression levels were decreased in glioma, and identified p70S6K1 as a novel direct target of miR-128. Overexpression of miR-128 suppressed p70S6K1 and its downstream signaling molecules such as HIF-1 and VEGF expression, and attenuated cell proliferation, tumor growth and angiogenesis. Forced expression of p70S6K1 can partly rescue the inhibitory effect of miR-128 in the cells. Taken together, these findings will shed light to the role and mechanism of miR-128 in regulating glioma tumor angiogenesis via miR-128/p70S6K1 axis, and miR-128 may serve as a potential therapeutic target in glioma in the future.
