Article Abstract
We show that testicular orphan nuclear receptor 4 (TR4) increases the expression of pyruvate carboxylase (PC) gene in 3T3-L1 adipocytes by direct binding to a TR4 responsive element in the murine PC promoter. While TR4 overexpression increased PC activity, oxaloacetate (OAA) and glycerol levels with enhanced incorporation of (14)C from (14)C-pyruvate into fatty acids in 3T3-L1 adipocytes, PC knockdown by short interfering RNA (siRNA) or inhibition of PC activity by phenylacetic acid (PAA) abolished TR4-enhanced fatty acid synthesis. Moreover, TR4 microRNA reduced PC expression with decreased fatty acid synthesis in 3T3-L1 adipocytes, suggesting that TR4-mediated enhancement of fatty acid synthesis in adipocytes requires increased expression of PC gene.

Objective: This study aims to elucidate how butyrate, a short-chain fatty acid, regulates the Treg/Th17 balance in ulcerative colitis (UC) via the cAMP-PKA/mTOR signaling pathway, offering novel treatment strategies.
Methods: Dextran sulfate sodium (DSS) was used to induce ulcerative colitis in a mouse model. Various butyrate dosages were administered to the mice.

Fatty acid synthase (FAS) is one of the most important enzymes in lipid biosynthesis, which can catalyze the reaction of acetyl-CoA and malonyl-CoA to produce fatty acids. However, the structure, function, and molecular mechanism of FAS regulating lipid synthesis in the fungus Mucor circinelloides are unclear. In the present study, two encoding fas genes in the high lipid-producing strain WJ11 and low lipid-producing strain CBS277.

Extensive research has confirmed that omega-3 fatty acids provide cardiovascular protection primarily by activating the G protein-coupled receptor 120 (GPR120) signaling pathway. However, natural activators of this receptor often lack sufficient strength and precision. TUG-891, a recently synthesized selective GPR120 activator, has displayed significant therapeutic potential in multiple disease.

Almost half of pregnant women globally are currently estimated to be overweight or obese. Rates of childhood obesity are also on the rise, in part because of increased consumption of dietary saturated fats. However, the long-term effect of peri- and postnatal high fat (HF) feeding on cognitive function and neuronal expression has not yet been investigated.
