WebHow is the entry point into the TCA cycle regulated? By Jasmine Rana. WebNov 14, 2024 · Recently, we and others have shown that GRK2 can translocate to cardiac mitochondria where it regulates metabolism. Notably, we found that phosphorylated GRK2 at S670 post- ischemia/reperfusion (IR) decreases glucose mitochondrial utilization and pyruvate dehydrogenase (PDH) activity.
WebApr 6, 2024 · Hypoxia-inducible factor-1α (HIF-1α) is ubiquitinated and degraded by prolyl-hydroxylase domain proteins (PHDs) in normoxia whereas the hypoxic condition impairs the function of PHD and stabilizes HIF-1α which in turn stimulates vascular endothelial growth factor (VEGF), tumor necrosis factor (TNF), IL-1 and IL-12 secretion. 67 It also induces … WebMay 4, 2015 · The letters of Constantin-Teodosiu et al. and Petersen et al. debate whether the glucose-fatty acid cycle (Randle cycle) operates in skeletal muscle (1, 2).Both groups cited some data of the original study to support their points.However, the well-known skeletal muscle heterogeneity was not mentioned, which seems critical to the point.
