The mammalian target of rapamycin (mTOR) protein kinase regulates a wide variety of cellular processes, including protein synthesis, yet the downstream translational program under the control of mTOR is poorly understood. Two recent studies by Hsieh et al. and Thoreen et al. now start to address this issue, and uncover a subset of genes translationally regulated by oncogenic mTOR signaling that may contribute to tumorigenesis.
哺乳动物雷帕霉素靶蛋白(mTOR)激酶调节着广泛的细胞过程,包括蛋白质合成,但目前对 mTOR 控制下的下游翻译程序知之甚少。Hsieh 等人和 Thoreen 等人最近的两项研究开始解决这个问题,并揭示了一组受致癌性 mTOR 信号转导翻译调控的基因,这些基因可能有助于肿瘤发生。
