选择性靶向癌细胞而非正常细胞的小分子抑制剂将是有价值的抗癌疗法。哺乳动物雷帕霉素复合物 2 (mTORC2) 靶点正在成为此类抑制剂的一个有前景的候选靶点。癌症生物学的最新研究表明,mTORC2 活性对于许多癌细胞类型的转化和活力至关重要,但在许多正常细胞中,mTORC2 活性的重要性较低。这些研究激起了人们对开发专门针对 mTORC2 的抑制剂的兴趣。然而,关于 mTORC2 的功能和调节及其在正常细胞和癌细胞中的功能,还有许多悬而未决的问题。在这里,我们总结了 mTORC2 信号传导生物学方面令人兴奋的新研究,并重点介绍了 mTOR 靶向治疗的现状和未来前景。
Small molecule inhibitors that selectively target cancer cells and not normal cells would be valuable anti-cancer therapeutics. The mammalian target of rapamycin complex 2 (mTORC2) is emerging as a promising candidate target for such an inhibitor. Recent studies in cancer biology indicate that mTORC2 activity is essential for the transformation and vitality of a number of cancer cell types, but in many normal cells, mTORC2 activity is less essential. These studies are intensifying interest in developing inhibitors that specifically target mTORC2. However, there are many open questions regarding the function and regulation of mTORC2 and its function in both normal and cancer cells. Here, we summarize exciting new research into the biology of mTORC2 signaling and highlight the current state and future prospects for mTOR-targeted therapy.
