WebJun 26, 2014 · p53 negatively regulates glycolysis enhanced by hypoxia. Recently, p53 has been reported to play a critical role in repressing the aerobic glycolysis under normoxic conditions through its transcriptional regulation of several target genes, including SCO2, TIGAR [13, 14].As a common feature of solid tumors, hypoxia is a driving force to switch … Webp53 and the Regulation of Glycolysis. The counterpoint to the ability of p53 to support oxidative phosphorylation is the ability of p53 to modulate glycolysis , although the details of this effect are somewhat complicated and likely to be highly tissue- and cell-type specific. Most straightforward are the functions of p53 that can contribute to ...
WebApr 12, 2024 · In this context, p53 exerts this metabolic regulation by regulating the expression of metabolic genes, such as p53-induced glycolysis and apoptosis regulator (TIGAR), glucose transporters, parkin, synthesis of cytochrome c oxidase 2 (SCO2), glutaminase 2 (GLS2), and malic enzyme; or modulating metabolic enzyme activities, … WebNational Center for Biotechnology Information
WebSep 3, 2024 · Recent research has identified some other roles of p53 in glycolysis. Tumor cells are in low glucose state due to the greatly increased consumption of glucose. Low-glucose conditions normally activate AMP-activated protein kinase (AMPK), whose activation induces phosphorylation of p53 at serine 15, and this phosphorylation is … WebNov 1, 2014 · P53 inhibits glucose transporter (GLUT 1-4-3) and the glycolytic enzyme PGM. Moreover, p53 inhibits glycolysis by promoting TIGAR expression. At the same time, p53 inhibits the ox-PPP by acting on G6PDH. The p53 role is tissue-specific. In muscle p53 enhances glycolysis by promoting the transcription of HK2.
