Omega-3 fatty acid protects cardiomyocytes against hypoxia-induced injury through targeting MiR-210-3p/CASP8AP2 axis
Mol Cell Biochem. 2021 Mar 31. doi: 10.1007/s11010-021-04141-1. Online ahead of print.ABSTRACTMicroRNAs (miRs) regulate diverse biological functions in both normal and pathological cellular conditions by post-transcriptional regulation of various genes expression. Nevertheless, the role of miRs in regulating the protective functions of omega-3 fatty acid in relation to hypoxia in cardiomyocytes remains unknown. The aim of this study was to investigate the effects of omega-3 fatty acid supplementation on cardiomyocyte apoptosis and further delineate the mechanisms underlying microRNA-210 (miRNA-210)-induced cardiomyocyte ap...

Omega-3 polyunsaturated fatty acids protect human hepatoma cells from developing steatosis through FFA4 (GPR120).
Abstract Protective effect of omega-3 polyunsaturated fatty acids (n-3 PUFA) on non-alcoholic fatty liver disease has been demonstrated. FFA4 (also known as GPR120; a G protein-coupled receptor) has been suggested to be a target of n-3 PUFA. FFA4 expression in hepatocytes has also been reported from liver biopsies in child fatty liver patients. In order to assess the functional role of FFA4 in hepatic steatosis, we used an in vitro model of liver X receptor (LXR)-mediated hepatocellular steatosis. FFA4 expression was confirmed in Hep3B and HepG2 human hepatoma cells. T0901317 (a specific LXR activator) induced lip...

Inhibitory effects of Omega-3 fatty acids on Early Brain Injury after Subarachnoid Hemorrhage in Rats: possible involvement of G protein-coupled receptor 120/β-arrestin2/TGF-β activated kinase-1 binding protein-1 signaling pathway.
This study was to examine the effects of omega-3 fatty acids on SAH-induced EBI. Two weeks before SAH, 30% Omega-3 fatty acids was administered by oral gavage at 1g/kg body weight once every 24hours. Specific siRNA for GPR120 was exploited. Terminal deoxynucleotidyl transferase dUTP nick end labeling, fluoro-Jade B staining, and neurobehavioral scores and brain water content test showed that omega-3 fatty acids effectively suppressed SAH-induced brain cell apoptosis and neuronal degradation, behavioral impairment, and brain edema. Western blot, immunoprecipitation, and electrophoretic mobility shift assays results showed t...
