BAF60a deficiency uncouples chromatin accessibility and cold sensitivity from white fat browning

Project description:Brown and beige fat share a remarkably similar transcriptional program that supports fuel oxidation and thermogenesis. The chromatin-remodeling machinery that governs genome accessibility and renders adipocytes poised for thermogenic activation remains elusive. Here we found that BAF60a, a subunit of the SWI/SNF chromatin-remodeling complexes, serves an indispensible role in cold-induced thermogenesis in brown fat. BAF60a maintains chromatin accessibility for key thermogenic genes in close proximity to PPARg and EBF2 binding sites. Surprisingly, fat-specific BAF60a inactivation triggers more pronounced browning of inguinal white adipose tissue that is linked to induction of MC2R, a receptor for the pituitary hormone ACTH. Elevated MC2R expression sensitizes adipocytes and BAF60a-deficient adipose tissue to thermogenic activation in response to ACTH stimulation. These observations reveal an unexpected dichotomous role of BAF60a-mediated chromatin remodeling in transcriptional control of brown and beige gene programs and illustrate a pituitary-adipose signaling axis in the control of thermogenesis.

Here we show that BAF60a, a subunit of the SWI/SNF chromatin-remodeling complexes, serves an indispensable role in cold-induced thermogenesis in brown fat.

Project description:As obesity has becoming an urged issue nowadays, delineation of the mechanisms of WAT tissue white-browning and beige adipose origin are of important topic. By the use of snRNA-seq, we can outline LepR cells play important role in the white-browning process and investigate the mechanisms participate at different white-browning treatments.

HMGNs Regulate White Adipocyte Browning By Stabilizing Cell Identity [RNA-Seq]

Project description:We report mRNA seq during time course of white preadipocyte browning from WT and HMGN1 and HMGN2 double knockout (DKO) mice . Moreover, we support our finding that loss of HMGN promotes white adipocyte browning with RNA seq of WT and DKO MEFs transdifferentiation into brown-like adipocytes.

Browning of white adipose tissue uncouples glucose uptake from insulin signaling.

Project description:Presence of thermogenically active adipose tissue in adult humans has been inversely associated with obesity and type 2 diabetes. While it had been shown that insulin is crucial for the development of classical brown fat, its role in development and function of inducible brown-in-white (brite) adipose tissue is less clear. Here we show that insulin deficiency impaired differentiation of brite adipocytes. However, adrenergic stimulation almost fully induced the thermogenic program under these settings. Although brite differentiation of adipocytes as well as browning of white adipose tissue entailed substantially elevated glucose uptake by adipose tissue, the capacity of insulin to stimulate glucose uptake surprisingly was not higher in the brite state. Notably, in line with the insulin-independent stimulation of glucose uptake, our data revealed that brite recruitment results in induction of solute carrier family 2 (GLUT-1) expression in adipocytes and inguinal WAT. These results for the first time demonstrate that insulin signaling is neither essential for brite recruitment, nor is it improved in cells or tissues upon browning.
