Notwithstanding that metabolic perturbations and dysregulated protein synthesis are salient features of cancer, the mechanism underlying coordination of cellular energy balance with mRNA translation (which is the most energy consuming process in the cell) is poorly understood. In this review, we focus on recently emerging insights in the molecular underpinnings of the cross-talk between oncogenic kinases, translational apparatus and cellular energy metabolism. In particular, we focus on the central signaling nodes that regulate these processes (e.g. the mechanistic/mammalian target of rapamycin MTOR) and the potential implications of these findings on improving the anti-neoplastic efficacy of oncogenic kinase inhibitors.
尽管代谢紊乱和蛋白质合成失调是癌症的显著特征,但细胞能量平衡与 mRNA 翻译(细胞中最耗能的过程)协调的机制仍知之甚少。在这篇综述中,我们专注于致癌激酶、翻译装置和细胞能量代谢之间串扰的分子基础方面新出现的见解。特别是,我们专注于调节这些过程的核心信号节点(例如,机械/哺乳动物雷帕霉素靶蛋白 MTOR),以及这些发现对提高致癌激酶抑制剂抗肿瘤疗效的潜在意义。
