Chrebp pathway
WebThe pathway for lipid, fatty acid and steroid metabolism is most significantly enriched by 48 novel ChREBP target genes ( p = 1.03 e ), supporting the central role of ChREBP in lipid metabolism. WebChREBP is a basic helix-loop helix/leucine zipper (bHLH/LZ) transcription factor, shuttling between the cytoplasm and nucleus in a glucose-responsive manner in …

Web1. a preparatory school. 2. a preliminary or warm-up activity or event; trial run. 3. preparation. 4. the act of preparing a patient for a medical or surgical procedure. ChREBP is translocated to the nucleus and binds to DNA after dephosphorylation of a p-Ser and a p-Thr residue by PP2A, which itself is activated by Xylulose-5-phosphate. Xu5p is produced in the pentose phosphate pathway when levels of Glucose-6-phosphate are high (the cell has ample glucose). In the liver, ChREBP mediates activation of several regulatory enzymes of glycolysis and lipogenesis including L-type pyruvate kinase (L-PK), acetyl CoA carboxylase, and fatty aci…
WebUsing overexpression and knockdown approaches, we show that PHLPP1 promotes the accumulation of neutral lipids, and augments cellular total cholesterol and free fatty acid (FFA) levels. RNA-Seq analysis uncovered PHLPP1 role in lipid metabolism pathways. PHLPP1 interacted with and modestly increased ChREBP recruitment to Fasn promoter. WebMar 6, 2024 · Glycolytic and lipogenic pathways were inhibited but the p53 pathway was activated after ChREBP knockdown. Taken together, ChREBP expression is associated with colon malignancy and it might contribute to cell proliferation via promoting anabolic pathways and inhibiting p53. In addition, ChREBP might represent a novel clinical …
WebDec 11, 2024 · Indeed, ChREBP is pivotal for adjusting glucose utilization to its availability by inducing the expression of genes involved in glycolysis and de novo lipogenesis (3). … WebApr 5, 2024 · Fructose metabolism is reviewed with a focus on the roles of the glucose-activating transcription factor Chrebp, fructolysis, and the polyol pathway; gene deletion of aldose reductase, ketohexokinase, and triokinase has been found to prevent the development of fructose-induced liver lipidosis. Excess fructose intake is associated with …
WebOct 1, 2010 · ChREBP is located in the cytoplasm when the glucose concentration is low and enters into the nucleus when the glucose concentration is high [54]. This would be secondary to a dephosphorylation of a serine (Ser196) phosphorylated by protein kinase A (PKA) in conditions of high cAMP concentrations such as the fasting state.
