Influence of fenofibrate treatment on triacylglycerides, diacylglycerides and fatty acids in fructose fed rats.

Fenofibrate (FF) lowers plasma triglycerides via PPARα activation. Here, we analyzed lipidomic changes upon FF treatment of fructose fed rats. Three groups with 6 animals each were defined as control, fructose-fed and fructose-fed/FF treated.

Discovery and pharmacological characterization of a novel small molecule inhibitor of phosphatidylinositol-5-phosphate 4-kinase, type II, beta.

Phosphatidylinositol-5-phosphate 4-kinase, type II, beta (PIP5K2B) is linked to the pathogenesis of obesity, insulin resistance and diabetes. Here, we describe the identification of a novel pyrimidine-2,4-diamine PIP5K2B inhibitor, designated SAR088. The compound was identified by high-throughput screening and subsequently characterized in vitro and in vivo.

Muscle-type specific intramyocellular and hepatic lipid metabolism during starvation in wistar rats.

The physiological dynamics of intramyocellular lipids (IMCLs) in different muscle types and of hepatocellular lipids (HepCLs) are still uncertain. The dynamics of IMCLs in the soleus, tibialis anterior, and extensor digitorum longus (EDL) muscles and HepCL during fed, 12- to 72-h starved, and refed conditions were measured in vivo by (1)H-magnetic resonance spectroscopy (MRS) in Wistar rats. Despite significant elevations of free fatty acids (FFAs) during starvation, HepCLs and IMCLs in soleus remained constant.
