Regulated IRE1α-dependent decay (RIDD)-mediated reprograming of lipid ...
2022年5月6日 · In this study, transcriptome and lipidome profiling of triple negative breast cancer cells subjected to pharmacological inhibition of IRE1α reveals changes in lipid metabolism …
Fat body Ire1 regulates lipid homeostasis through the Xbp1s …
Here we report a novel catabolic role of Ire1 in regulating lipid mobilization in Drosophila. We found that Ire1 is activated by nutrient deprivation, and, importantly, fat body-specific Ire1 …
Silencing of lipid metabolism genes through IRE1α-mediated ... - PubMed
2012年10月3日 · XBP1 deficiency triggers feedback activation of its upstream enzyme IRE1α, instigating regulated IRE1-dependent decay (RIDD) of cytosolic mRNAs. Here, we identify …
Adipocyte IRE1α promotes PGC1α mRNA decay and restrains
2022年9月19日 · Here we show that inositol-requiring enzyme 1α (IRE1α), a key ER stress sensor and signal transducer, acts in both white and beige adipocytes to impede beige fat …
Pharmacologic IRE1/XBP1s activation promotes systemic adaptive …
2022年2月1日 · Here, we report the effects of a XBP1s-selective pharmacological IRE1 activator, IXA4, in diet-induced obese (DIO) mice. IXA4 transiently activates protective IRE1/XBP1s …
Silencing of Lipid Metabolism Genes through IRE1α ... - Cell Press
XBP1 ablation in liver causes profound hypolipidemia in mice, highlighting its critical role in lipid metabolism. XBP1 deficiency triggers feedback activation of its upstream enzyme IRE1α, …
Fat body Ire1 regulates lipid homeostasis through the Xbp1s
2021年7月7日 · The endoplasmic reticulum (ER)-resident transmembrane protein kinase/RNase Ire1 is a conserved sensor of the cellular unfolded protein response and has been implicated …
IRE-1 and HSP-4 Contribute to Energy Homeostasis via ... - Cell Press
2009年5月6日 · We demonstrate that IRE-1, an ER protein known to be involved in the unfolded protein response, and HSP-4, an ER chaperone, regulate expression of the novel fasting …
Stress sensor Ire1 deploys a divergent transcriptional program in ...
To systematically validate yeast mutants that disrupt ER membrane homeostasis, we identified a lipid bilayer stress (LBS) sensor in the UPR transducer protein Ire1, located at the interface of …
Regulated IRE1α-dependent decay (RIDD)-mediated reprograming of lipid ...
2022年5月6日 · Inhibition of IRE1α, leads to DGAT2-dependent accumulation of TAGs in lipid droplets and sensitizes cells to nutritional stress, which is rescued by treatment with the …
