The mTOR pathway in hepatic malignancies
Mamatha Bhat, Nahum Sonenberg, Gregory J. Gores – 13 February 2013 – The mechanistic/mammalian target of rapamycin (mTOR) pathway plays a critical role in cellular metabolism, growth, and proliferation and has been evaluated as a target for therapy in various malignancies. The mTOR pathway is a major tumor‐initiating pathway in hepatocellular carcinoma, with up‐regulation seen in up to 50% of tumors. Metformin, which represses mTOR signaling by activating adenosine monophosphate–activated protein kinase, has been shown to decrease liver carcinogenesis in population studies.
