Polyphenol-rich foods are gaining popularity due to their potential beneficial effects in the prevention and treatment of cancer. Foxtail millet is one of the important functional foods, riches in a variety of biologically active substance. Our previous study showed that ferulic acid (FA) and p-coumaric acid (p-CA) are the main anticancer components of foxtail millet bran, and the two have a significant synergistic effect. In the present study, the clinical application potential of FA and p-CA (FA + p-CA) were evaluated in vivo and in vitro. The FA and p-CA target gene enrichment analysis discovered that FA + p-CA were associated with aerobic glycolysis. It was further shown that FA + p-CA remodel aerobic glycolysis by inhibiting the glycolysis-associated lncRNA 495810 and the glycolytic rate-limiting enzyme M2 type pyruvate kinase (PKM2). Moreover, PKM2 expression was positively correlated with lncRNA 495810. More interestingly, the exogenous expression of lncRNA 495810 eliminated the inhibitory effects of FA + p-CA on aerobic glycolysis. Collectively, FA + p-CA obstruct the aerobic glycolysis of colorectal cancer cells via the lncRNA 495810/PKM2 axis, which provides a nutrition intervention and treatment candidate for colorectal cancer.
多酚类丰富的食物因其在癌症的预防和治疗方面的潜在有益作用而越来越受欢迎。黍米是一种重要的功能性食品,富含多种具有生物活性的物质。我们之前的研究表明,阿魏酸(FA)和对香豆酸(p-CA)是黍米糠中主要的抗癌成分,两者具有显著的协同作用。本研究在体内和体外评估了 FA 和 p-CA(FA + p-CA)的临床应用潜力。FA 和 p-CA 的靶向基因富集分析发现,FA + p-CA 与有氧糖酵解有关。进一步表明,FA + p-CA 通过抑制与糖酵解相关的长链非编码 RNA 495810 和糖酵解限速酶 M2 型丙酮酸激酶(PKM2)来重塑有氧糖酵解。此外,PKM2 表达与 lncRNA 495810 呈正相关。更有趣的是,lncRNA 495810 的外源性表达消除了 FA + p-CA 对有氧糖酵解的抑制作用。总之,FA + p-CA 通过 lncRNA 495810/PKM2 轴阻碍结直肠癌细胞的有氧糖酵解,为结直肠癌提供了一种营养干预和治疗的候选药物。
