Oxidized Phosphatidylcholines Trigger TRPA1 and Ryanodine Receptor-dependent Airway Smooth Muscle Contraction.

Asthma pathobiology includes oxidative stress that modifies cell membranes and extracellular phospholipids. Oxidized phosphatidylcholines (OxPCs) in lung lavage from allergen-challenged human participants correlate with airway hyperresponsiveness and induce bronchial narrowing in murine thin-cut lung slices. OxPCs activate many signaling pathways, but mechanisms for these responses are unclear.

Dynamic changes in virus-induced volatiles in cotton modulate the orientation and oviposition behavior of the whitefly .

Manipulation of insect vector behavior by virus-induced plant volatiles is well known. But how the viral disease progression alters the plant volatiles and its effect on vector behavior remains less explored. Our studies tracked changes in volatile profile in progressive infection stages of cotton leaf curl virus (CLCuV) infected plants and their effect on behavior.

Coagonist of glucagon-like peptide-1 and glucagon receptors ameliorates nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is often associated with obesity and type 2 diabetes. Coagonists of glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR) are under clinical investigation for the treatment of obesity and type 2 diabetes. In this study, we have demonstrated the effect of a balanced coagonist in the treatment of NAFLD using mouse models.

Coagonist of GLP-1 and Glucagon Receptor Ameliorates Development of Non-Alcoholic Fatty Liver Disease.

Background: Obesity, diabetes and dyslipidemica are the key pathogenic stimulus that enhances progression of Non-Alcoholic Fatty Liver Disease (NAFLD). Coagonist of Glucagon Like- Peptide-1 (GLP-1) Receptor (GLP-1R) and Glucagon Receptor (GCGR) are being evaluated for obesity and diabetes. GLP-1 analogs have shown to reverse diabetes and obesity.

Coagonist of GLP-1 and glucagon decreases liver inflammation and atherosclerosis in dyslipidemic condition.

Dyslipidemia enhances progression of atherosclerosis. Coagonist of GLP-1 and glucagon are under clinical investigation for the treatment of obesity and diabetes. Earlier, we have observed that coagonist reduced circulating and hepatic lipids, independent of its anorexic effects.

Central administration of coagonist of GLP-1 and glucagon receptors improves dyslipidemia.

Coagonists of Glucagon-like peptide-1 (GLP-1) and glucagon receptors are under clinical investigation for treatment of obesity associated with diabetes. In addition to their role in glucose homeostasis, GLP-1 and glucagon modulate lipid metabolism. In this study, we have investigated the role of central GLP-1 receptor (GLP-1R) and glucagon receptor (GCGR) activation in regulation of lipid metabolism in cholesterol-fed hamsters.

Balanced Coagonist of GLP-1 and Glucagon Receptors Corrects Dyslipidemia by Improving FGF21 Sensitivity in Hamster Model.

Hyperlipidemia is often associated with obesity and diabetes, and can lead to serious complications like atherosclerosis and fatty liver disease. Coagonist of GLP-1 and glucagon receptors is a therapy under clinical investigation for treatment of obesity and diabetes. In this study, we have characterized the mechanism of hypolipidemic effect of a balanced coagonist using high cholesterol-fed hamsters.

Central and Peripheral Glucagon Reduces Hyperlipidemia in Rats and Hamsters.

Increased lipid levels in blood contribute to increasing the risk of diabetic complications. Glucagon exerts lipid lowering effects in diabetic state. However, the mechanism behind the lipid reduction by glucagon independent of glucose homeostasis is not well understood.

Involvement of TACE in colon inflammation: a novel mechanism of regulation via SIRT-1 activation.

TNF-α converting enzyme (TACE) processes the membrane TNF-α to release the bioactive soluble TNF-α. Several evidences suggest the involvement of TNF-α and TACE in inflammatory bowel disease (IBD). Tissue inhibitor of metalloproteinase (TIMP)-3, an endogenous inhibitor of TACE, is positively associated with silent information regulator (SIRT)-1.

Selective inhibition of tumor necrosis factor-α converting enzyme attenuates liver toxicity in a murine model of concanavalin A induced auto-immune hepatitis.

Emerging evidence suggest that tumor necrosis factor (TNF)-α plays a major role in pathogenesis of auto-immune hepatitis (AIH) induced liver injury. Blockade of TNF-α synthesis or bio-activity protects against experimental AIH. TNF-α converting enzyme (TACE) is a member of the ADAM (a disintegrin and metalloproteinase) family which processes precursor TNF-α to release soluble TNF-α.
