Interplay between fish oil, obesity and cardiometabolic diabetes.

Diabetes, dyslipidemia, obesity, and cardiac dysfunction are the hallmarks of the cardiometabolic syndrome. Pathogens include hypercoagulability, inflammation, endothelial dysfunction, and oxidative stress. Increased white fat, nonalcoholic fatty liver disease, diabetes, and cardiovascular disease are caused by obesity. Depression increases the risk of future obesity, a surprising link between obesity and neuropathology. High glucose levels, abnormal lipids, and metabolic syndrome are the root causes of CVD associated with diabetes. Diets high in fat induce insulin resistance and liver fat. Inflammation, diminished insulin signaling, and ectopic lipid accumulation are the causes of ectopic lipid accumulation. Polyunsaturated fatty acids with eicosapentaenoic acid and docohexasonoic acid inhibit the synthesis of triglycerides and increase their clearance. Omega-3 regulates the nervous system, blood pressure, hematic clotting, glucose tolerance, and inflammation. However, anxiety and depression can cause cardiovascular disease. It has been shown that PUFAs found in fish oil can improve glucose and lipid metabolism, cardiac membrane composition, and inflammation in the body. By repairing the dysregulation of metabolic syndrome, fish oil is a potential therapeutic target for cardiovascular diseases.

The Pathophysiologic Role of Gelsolin in Chronic Kidney Disease: Focus on Podocytes.

Chronic kidney disease (CKD) is normally related to proteinuria, a common finding in a compromised glomerular filtration barrier (GFB). GFB is a structure composed of glomerular endothelial cells, the basement membrane, and the podocytes. CKD with podocyte damage may be associated with actin cytoskeleton reorganization, resulting in podocyte effacement. Gelsolin plays a critical role in several diseases, including cardiovascular diseases and cancer. Our current study aimed to determine the connection between gelsolin and podocyte, and thus the mechanism underlying podocyte injury in CKD. Experiments were carried out on Drosophila to demonstrate whether gelsolin had a physiological role in maintaining podocyte. Furthermore, the survival rate of gelsolin-knocked down Drosophila larvae was extensively reduced after AgNO3 exposure. Secondly, the in vitro podocytes treated with puromycin aminonucleoside (PAN) enhanced the gelsolin protein expression, as well as small GTPase RhoA and Rac1, which also regulated actin dynamic expression incrementally with the PAN concentrations. Thirdly, we further demonstrated in vivo that GSN was highly expressed inside the glomeruli with mitochondrial dysfunction in a CKD mouse model. Our findings suggest that an excess of gelsolin may contribute to podocytes damage in glomeruli.
