Activation of thermogenic brown adipose tissue (BAT) and inducible beige adipose tissue (BeAT) is triggered by environmental or metabolic stimuli, including cold ambient temperatures and nutrient stress. Thioesterase superfamily member 1 (Them1), a long-chain fatty acyl-CoA thioesterase that is enriched in BAT, suppresses acute cold-induced thermogenesis. Here, we demonstrate that expression was induced in BAT and BeAT by the carbohydrate response element binding protein (ChREBP) in response to chronic cold exposure or to the activation of the integrated stress response (ISR) by nutrient excess.

Article Synopsis
  • Them1 is an enzyme that regulates fatty acid oxidation and glucose production, particularly in thermogenic adipose tissue and the liver, and is a potential target for treating non-alcoholic fatty liver disease (NAFLD).
  • Researchers screened for small molecule inhibitors that specifically target Them1's activity and identified two effective allosteric inhibitors that bind to its START domain.
  • These inhibitors not only increased fatty acid oxidation in mouse cells but also decreased glucose production, making Them1 a promising avenue for pharmacological intervention in NAFLD.

Students are exposed to a variety of stressors that can negatively affect their health and performance. Using an Ambulatory Assessment approach, this study investigated whether and how positive affect (PA) and negative affect (NA) changed in response to real-life stressors in sports students. In addition, the study investigated how physical activity (PhyA) moderated affective reactions to stressors.

The transition to continuous biomanufacturing has led to renewed interest in alternative approaches for downstream processing of monoclonal antibody (mAb) products. In this study, we examined the potential of using high-performance countercurrent membrane purification (HPCMP) for the removal of host cell proteins (HCPs) derived from Chinese Hamster Ovary cells in the purification of a mAb. Initial studies used several model proteins to identify appropriate operating conditions for the hollow fiber membrane modules.

Cyclic AMP-responsive element-binding protein H (CREBH encoded by Creb3l3) is a transcription factor that regulates the expression of genes that control lipid and glucose metabolism as well as inflammation. CREBH is upregulated in the liver under conditions of overnutrition, and mice globally lacking the gene (CREBH) are highly susceptible to diet-induced obesity, insulin resistance, and hepatic steatosis. The net protective effects of CREBH have been attributed in large part to the activities of fibroblast growth factor (Fgf)-21 (Fgf21), a target gene that promotes weight loss, improves glucose homeostasis, and reduces hepatic lipid accumulation.
