Characterization of VPS34-IN1, a selective inhibitor of Vps34, reveals that the phosphatidylinositol 3-phosphate-binding SGK3 protein kinase is a downstream target of class III phosphoinositide 3-kinase [PDF]
The Vps34 (vacuolar protein sorting 34) class III PI3K (phosphoinositide 3-kinase) phosphorylates PtdIns (phosphatidylinositol) at endosomal membranes to generate PtdIns(3)P that regulates membrane trafficking processes via its ability to recruit a ...

Exendin-4 reduces food intake via the PI3K/AKT signaling pathway in the hypothalamus
Exendin-4 (EX-4), a glucagon-like peptide-1 (GLP-1) receptor agonist, has been shown to reduce food intake and to increase proopiomelanocortin (POMC) gene expression in the hypothalamus. In this study, we examined the potential neural mechanisms by which

Stimulation of a glycosyl-phosphatidylinositol-specific phospholipase by insulin and the sulfonylurea, glimepiride, in rat adipocytes depends on increased glucose transport [PDF]
. Lipoprotein lipase (LPL) and glycolipidanchored cAMP-binding ectoprotein (Gcel) are modified by glycosyl-phosphatidylinositol (GPI) in rat adipocytes, however, the linkage is potentially unstable. Incubation of the cells with either insulin (0.1-30 nM)

Insights into Activation Mechanisms of Store-Operated TRPC1 Channels in Vascular Smooth Muscle. [PDF]
In vascular smooth muscle cells (VMSCs), the stimulation of store-operated channels (SOCs) mediate Ca2+ influx pathways which regulate important cellular functions including contraction, proliferation, migration, and growth that are associated with the ...

Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.
