title: Effects of treadmill running and rutin on lipolytic signaling pathways and TRPV4 protein expression in the adipose tissue of diet-induced obese mice.
abstract: To explore the effects of rutin and exercise on high-fat diet (HFD)-induced disrupted lipolytic signaling, adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) signaling, transient receptor potential cation channel subfamily V member 4 (TRPV4) and its associated protein expression, and whether depot-specific effects existed. C57BL/6J mice were randomized into five groups: chow group, HFD, HFD plus rutin intervention group (HR), HFD combined with treadmill running group (HE), and HFD combined with treadmill running and rutin intervention group (HRE). At the end of the 16-week intervention, lipolytic markers, AMPK signaling pathways, TRPV4, and peroxisome proliferator-activated receptor gamma coactivator 1α + β (PGC-1α + β) from adipose tissue were measured by western blotting. In epididymal adipose tissue, HFD resulted in significant reduction in the phosphorylation of hormone sensitive lipase at serine660 (p-HSL660), perilipin A, phosphoenolpyruvate carboxykinase (PEPCK), p-AMPK, and p-acetyl-CoA carboxylase (ACC) protein expression. Exercise intervention and exercise plus rutin completely restored p-HSL660, perilipin A, PEPCK, p-AMPK, and p-ACC protein expression to normal level. HFD and HR groups have reduced expression of PGC-1α + β, exercise, and exercise plus rutin completely restored PGC-1α + β expression to normal level. In subcutaneous adipose tissue, HFD elevated TRPV4, exercise, and exercise plus rutin completely reduced TRPV4 to normal level. HR, HE, and HRE group have increased PGC-1α + β. In conclusion, depot-specific effects existed in regards to how rutin and exercise affect lipolytic signaling and p-AMPK, as well as TRPV4 and PGC-1α + β expression.
