WebJan 14, 2024 · Metformin inhibits mTOR via a different mechanism than everolimus and rapamycin and it has a significantly more benign side-effect profile. At the dose used in this study, it does not appear to be as potent an mTOR inhibitor as rapamycin or everolimus and does not have such a dramatic effect on the hamartomas associated with TSC.

Growth factors activate RTKs and the downstream signaling cascades PI3K/AKT and Ras/Erk, resulting in inhibition of the TSC complex, which functions as a GAP for the mTORC1 upstream effector Rheb GTPase. In contrast, cellular stressors, ... WebThe high frequency of TSC mutations has provided key and novel explanation in addressing the underlying molecular mechanism for the TSC loss in hyperactivation of mTOR signalling. We further demonstrated, through PDTX models carrying TSC2 -inactivating mutations, that hyperactivation of mTOR signalling via mutational disruption of TSC regulation is … WebJan 29, 2024 · Despite the common genetic background, it appears that the tumors with TSC/mTOR mutations represent a diverse group of distinct renal neoplasms. A number of recently described renal tumor entities share an eosinophilic/oncocytic morphology, somewhat solid architectural growth pattern, and tendency to present as low-stage tumors. lordstown electric pickup
