Salsalate improves glucose intolerance and dyslipidemia in type 2 diabetes patients, but the mechanism is still unknown. The aim of the current study was to unravel the molecular mechanisms involved in these beneficial metabolic effects of salsalate by treating mice with salsalate during and after development of high-fat diet-induced obesity. We found that salsalate attenuated and reversed high-fat diet-induced weight gain, in particular fat mass accumulation, improved glucose tolerance, and lowered plasma triglyceride levels. Mechanistically, salsalate selectively promoted the uptake of fatty acids from glycerol tri[(3)H]oleate-labeled lipoprotein-like emulsion particles by brown adipose tissue (BAT), decreased the intracellular lipid content in BAT, and increased rectal temperature, all pointing to more active BAT. The treatment of differentiated T37i brown adipocytes with salsalate increased uncoupled respiration. Moreover, salsalate upregulated Ucp1 expression and enhanced glycerol release, a dual effect that was abolished by the inhibition of cAMP-dependent protein kinase (PKA). In conclusion, salsalate activates BAT, presumably by directly activating brown adipocytes via the PKA pathway, suggesting a novel mechanism that may explain its beneficial metabolic effects in type 2 diabetes patients.

Salsalate plays beneficial roles for ameliorating hyperglycemia and dyslipidemia in type 2 diabetes patients, but the underlying mechanisms are still poorly understood. In this study, by administering salsalate to mice fed with high fat diet and examining how salsalate rectifies metabolic dysfunction in these obese mice, we found that salsalate stimulated body temperature and attenuated body weight gain without affecting food intake. Our results showed that salsalate application decreased lipid accumulation in liver and epididymal white adipose tissue (eWAT), inhibited hepatic gluconeogenesis and improved insulin signaling transduction in eWAT. In addition, salsalate increased the expression of genes related to glucose and fatty acid transport and oxidation in skeletal muscle. Our results also showed that expression of genes in mitochondrial uncoupling and mitochondrial electron transport are strengthened by salsalate. Moreover, sarcolipin (Sln) and sarcoplasmic reticulum Ca2+ ATPase 2 (Serca2) in skeletal muscle were enhanced in salsalate-treated mice. Together, our data suggest that the beneficial metabolic effects of salsalate may depend, at least in part, on skeletal muscle thermogenesis via activation of mitochondrial uncoupling and the axis of Sln/Serca2a.
