摘要:

探讨miR-128a介导的磷酸果糖激酶通过糖代谢促进非小细胞肺癌增殖的机制。采用生信分析方法预测与PFK作用的miRNA; 采用定量PCR方法 (qRT-PCR)方法在肿瘤组织和细胞样本上验证该分子表达量; 改变该分子表达量, 分别使用免疫荧光、Western blotting检测肺癌细胞的凋亡程度、PFK及低氧诱导因子1-α (hypoxia-inducible factor 1α, HIF1-α)表达水平。结果显示, 生信分析显示miR-128a可以靶向PFK; miR-128a在肺癌细胞中表达量明显降低, 过表达其水平, 细胞凋亡数目增多, 而PFR、HIF1-α蛋白表达水平降低。结果说明miR-128a在肺癌中表达降低, 通过降低PFK、HIF1-α表达促进了细胞增殖。

Abstract:

This study investigated the mechanism by which miR-128a, mediated through phosphofructokinase (PFK), fostered proliferation in non-small cell lung cancer (NSCLC) via glycolysis. Bioinformatics analysis was employed to predict microRNAs (miRNAs) involved in the interaction with PFK. Subsequently, the expression levels of the identified molecule were validated using qRT-PCR in both tumor tissues and cell samples. The modulation of this molecule’s expression was executed, and techniques such as immunofluorescence and Western blotting analysis were employed to evaluate apoptosis levels, PFK expression, and hypoxia-inducible factor-1 alpha (HIF1-α) expression in lung cancer cells. The results indicated that bioinformatics analysis revealed miR-128a as a potential targeting molecule for PFK. The expression level of miR-128a was significantly diminished in lung cancer cells. Overexpression of miR-128a led to increased apoptosis and reduced protein expression levels of PFK and HIF1-α. Conversely, decreased expression of miR-128a in lung cancer cells promoted cell proliferation by downregulating PFK and HIF1-α expression levels.
