Adding Polyamine Metabolism to the mTORC1 Toolkit in Cell Growth and Cancer

Dev Cell. 2017 Jul 24;42(2):112-114. doi: 10.1016/j.devcel.2017.07.004.


The mammalian/mechanistic target of rapamycin complex 1 (mTORC1) is a major nutrient sensor and regulator of cellular metabolic flux. Reporting recently in Nature, Zabala-Letona et al. (2017) show that mTORC1 regulates an additional branch of metabolism in the cell-polyamine synthesis-that is important for prostate cancer tumorigenicity.
