Mitochondria-cytosolic crosstalk and histone acetylation in differentiating T cells. Weblevel of Glut1 acetylation. Stimulation of glucose uptake was greatly reduced by chemical inhibition of Sirt2 or mTOR–RAPTOR. We propose that mitochondrial dysfunction triggers LKB1-mediated AMPK activation, which stimulates Sirt2 phosphorylation, leading to activation of mTOR–RAPTOR and Glut1-mediated glucose uptake.
Glut1 acetylation
Did you know?
WebGLUT1 deficiency is a rare genetic disorder. It is caused by variants in the SLC2A1 gene. SLC2A1 provides instructions for producing GLUT1. In the brain, the GLUT1 protein is involved in moving glucose from the bloodstream into the cerebrospinal fluid (CSF), which surrounds the brain. Glucose is the brain's main energy source. WebSince lysine acetyltransferase that mediates protein acetylation is produced by acetyl CoA, increased fatty acid metabolism leads to an increase in protein acetylation levels [34]. In the insulin ...
WebMar 26, 1999 · Hypertrophic induction of the Glut1 promoter was also partially sensitive to inhibition of the phosphatidylinositol 3-kinase pathway and was strongly inhibited by cotransfection with dominant-negative Ras. Thus, Ras activation and pathways downstream of Ras mediate induction of the Glut1 promoter during myocardial hypertrophy. WebFeb 11, 2024 · Mechanistically, we show that BPIFB1 can inhibits JNK/AP1 signaling which leads to inhibition of glucose transporter 1 (GLUT1) transcription and glycolysis, consequently, resulting in reducing histone H3K27 acetylation and decreasing the expression of vasculogenic mimicry-related VEGFA, VE-cadherin, and MMP2.
WebA group of related glucose transporters (Glut1-5 and 7) mediate the facilitated diffusion of glucose in nonepithelial mammalian tissues. Within insulin-responsive tissues such as muscle and fat, Glut1 contributes to basal glucose uptake while Glut4 is responsible for insulin-stimulated glucose transport. Glut4 is a 12-transmembrane domain ... WebNational Center for Biotechnology Information
WebJun 18, 2024 · Recently, the structure and distribution pattern of GLUT1 has also drawn wide concern. Some studies have found that it is an inward-open uniporter with a single N-glycosylation site (10, 11), and some have showed a markedly punctate staining pattern of GLUT1 on cell membranes under deconvolution fluorescence microscopy ().However, …
