WebMay 7, 2024 · Consequently, whereas PKCζ-LKB1-AMPK-TSC1/2 inhibited mTORC1 in the context of biliverdin/BVRA signaling in leukocytes, insulin suppressed TLR4 signaling via mTORC2-Akt Ser473 and Foxo1/3 without ... WebApr 29, 2013 · An important down-stream target of AMPK is the TSC2 tumor suppressor, a “gatekeeper” for mTORC1 signaling that suppresses mTORC1 in response to energy …
WebFor example, AMPK inhibits mTORC1 during energetic stress through at least two mechanisms involving AMPK-mediated phosphorylation of Tsc2 on an activating site and raptor on inhibitory sites (23, 24). The regulation and function of mTORC2 remains less well defined than mTORC1. Webp-AMPK phosphorylates TSC1:TSC2. Activated AMPK (phosphorylated on the alpha subunit and with AMP bound) phosphorylates TSC2 (also known as tuberin) on Ser-1387, thereby …
WebMay 20, 2024 · AMPK phosphorylation also increases the transcription activity of FOXOs. Emerging evidence suggests that FOXO factors act as a tumor suppressor in a variety of cancers . The model represents mTORC1 inhibition by AMPK via its stimulation of ULK1 and TSC1_TSC2. AMPK is also known to suppress mTORC1 by phosphorylating Raptor .
