Overnutrition disrupts circadian metabolic rhythms by mechanisms that are not well understood. Here, we show diet-induced obesity (DIO) causes massive remodeling of enhancer activity in mouse liver, triggering synchronous high-amplitude both fatty acid (FA) synthesis and oxidation. SREBP expression was rhythmically induced DIO, leading to FA and, surprisingly, oxidation (FAO). DIO similarly caused a rhythm PPARα, which also required for FAO. Provision pharmacological activator PPARα abrogated the requirement FAO (but synthesis), suggesting indirectly controls via production endogenous ligands. The imparted time-of-day-dependent responsiveness lipid-lowering drugs. Thus, acquisition rhythmicity non-core clock components SREBP1 remodels gene transcription response overnutrition enables chronopharmacological approach disorders.

Abstract The maintenance of iron homeostasis is essential for proper endocrine function. A growing body evidence suggests that imbalance a key factor in the development several diseases. Nowadays, ferroptosis, an iron-dependent form regulated cell death, has become increasingly recognized as important process to mediate pathogenesis and progression type 2 diabetes mellitus (T2DM). It been shown ferroptosis pancreas β cells leads decreased insulin secretion; liver, fat, muscle induces resistance. Understanding mechanisms concerning regulation metabolism T2DM may lead improved disease management. In this review, we summarized connection between metabolic pathways molecular T2DM. Additionally, discuss potential targets treating analysis current limitations future directions these novel treatment targets.
