Hydrogen sulfide promoted retinoic acid-related orphan receptor α transcription to alleviate diabetic cardiomyopathy
Biochem Pharmacol. 2023 Aug 15:115748. doi: 10.1016/j.bcp.2023.115748. Online ahead of print.ABSTRACTDiabetic cardiomyopathy (DCM) is one serious and common complication in diabetes without effective treatments. Hydrogen sulfide (H2S) fights against a variety of cardiovascular diseases including DCM. Retinoic acid-related orphan receptor α (RORα) has protective effects on cardiovascular system. However, whether RORα mediates the protective effect of H2S against DCM remains unknown. The present research was to explore the roles and mechanisms of RORα in H2S against DCM. The study demonstrated that H2S donor sodium hydro...

Blockage of MyD88 in cardiomyocytes alleviates cardiac inflammation and cardiomyopathy in experimental diabetic mice
In this study, we first found that MyD88 expression was increased in cardiomyocytes of diabetic mouse hearts. In cultured cardiomyocytes, MyD88 inhibition either by siRNA or by small-molecular inhibitor LM8 markedly blocked TLR4-MyD88 complex formation, reduced pro-inflammatory mitogen-activated protein kinases/nuclear factor-κB (MAPKs/NF-κB) cascade activation and decreased pro-inflammatory cytokine expression under high glucose condition. Moreover, pharmacologic inhibition of MyD88 by LM8 showed significantly anti-inflammatory, anti-hypertrophic and anti-fibrotic effects in the hearts of both type 1 and type 2 diabetic...

Resolvin D3 improves the impairment of insulin signaling in skeletal muscle and nonalcoholic fatty liver disease through AMPK/autophagy-associated attenuation of ER stress
Biochem Pharmacol. 2022 Aug 7:115203. doi: 10.1016/j.bcp.2022.115203. Online ahead of print.ABSTRACTResolvin D3 (RD3), an endogenous lipid mediator derived from omega-3 fatty acids, has been documented to attenuate inflammation in various disease models. Although it has been reported that omega-3 fatty acids attenuate metabolic disorders, the roles of RD3 in insulin signaling in skeletal muscle and hepatic lipid metabolism remain unclear. In the current study, we examined the role of RD3 in skeletal muscle insulin resistance and hepatic steatosis using in vitro and in vivo obesity models. In mouse primary hepatocytes, RD3 ...

Tetrahydroxystilbene glycoside improves endothelial dysfunction and hypertension in obese rats: the role of omentin-1
CONCLUSIONS: Down-regulation of omentin-1 induces endothelial dysfunction and hypertension in obesity. TSG treatment (at least partially) increases omentin-1 via promoting binding of PPAR-γ and Itln-1 promoter in adipose tissues, subsequently exerts protective effects on endothelial function via activating Akt/eNOS/NO signaling and attenuating oxidative/nitrative stress. These results suggest that TSG could be developed as a promising anti-hypertension agent that protects against endothelial dysfunction and obesity-associated cardiovascular diseases.PMID:33647262 | DOI:10.1016/j.bcp.2021.114489

Rosmarinic acid inhibits oxLDL-induced inflammasome activation under high-glucose conditions through downregulating the p38-FOXO1-TXNIP pathway.
In this study, we aimed to investigate the protective effect of rosmarinic acid against diabetic atherosclerosis and the related signaling pathway. oxLDL-mediated oxidative stress upregulated thioredoxin-interacting protein (TXNIP) and subsequently induced binding of TXNIP to NLRP3 to mediate NLRP3 inflammasome assembly and activation under HG conditions in ECs. Reactive oxygen species (ROS) scavengers, p38 and FOXO1 inhibitors and TXNIP siRNA inhibited TXNIP protein upregulation and NLRP3 inflammasome assembly and activation. Rosmarinic acid abrogated TXNIP protein upregulation and the interaction between TXNIP and NLRP3 ...

DEL-1 ameliorates high-fat diet-induced insulin resistance in mouse skeletal muscle through SIRT1/SERCA2-mediated ER stress suppression.
Abstract Inflammation and endoplasmic reticulum (ER) stress are associated with the development of insulin resistance and diabetes. Developmental endothelial locus-1 (DEL-1) enhances efferocytosis by macrophage and suppresses inflammatory response. However, effects of DEL-1 on ER stress-mediated insulin resistance in skeletal muscle remain unclear. Here, DEL-1 treatment augmented SIRT1 expression in C2C12 myocytes, thereby increasing SERCA2 expression in a dose-dependent fashion, and attenuated ER stress and insulin resistance under palmitate treatment condition. SIRT1/SERCA2 knockdown abrogated effects of DEL-1 o...

Modulation of Sirt1/NF- κB interaction of evogliptin attributed to inhibition of vascular inflammatory response leading to attenuation of atherosclerotic plaque formation.
This study demonstrates that the protective effect of evogliptin on atherosclerotic progression via inhibition of vascular inflammation. The findings imply that evogliptin has potential for anti-atherosclerosis therapy that targets arterial inflammation. PMID: 31421133 [PubMed - as supplied by publisher]

Tanshinone IIA suppresses Fc εRI-mediated mast cell signaling and anaphylaxis by activation of the Sirt1/LKB1/AMPK Pathway.
In conclusion, Tan IIA suppresses FcεRI-mediated mast cell activation and anaphylaxis through activation of the inhibitory Sirt1-LKB1-AMPK pathway. Thus, Tan IIA may be useful as a new therapeutic agent for mast cell-mediated allergic diseases. PMID: 29674003 [PubMed - as supplied by publisher]
