Melatonin ameliorates diabetic hyperglycaemia-induced impairment of Leydig cell steroidogenic function through activation of SIRT1 pathway
CONCLUSIONS: These findings suggest that SIRT1 pathway plays essential roles in the pleiotropic actions of melatonin on Leydig cells and in the prevention of hyperglycaemia-induced steroidogenic dysfunction. The stimulatory action of melatonin on SIRT1 pathway is related to oxidative stress and its antioxidant property. Our data provide new evidence for the relationship of melatonin and SIRT1 pathway in the context of hyperglycaemia, and melatonin as a combination therapy may be useful to combat DM-related complications, especially male reproductive system injury.PMID:35962432 | DOI:10.1186/s12958-022-00991-6

Melatonin attenuates MPP < sup > + < /sup > -induced apoptosis via heat shock protein in a Parkinson's disease model
Biochem Biophys Res Commun. 2022 Jul 1;621:59-66. doi: 10.1016/j.bbrc.2022.06.099. Online ahead of print.ABSTRACTHeat shock proteins (HSPs) play an essential role as molecular chaperones to prevent abnormal protein aggregation and misfolding. Moreover, they protect dopamine neurons from oxidative stress, inflammation, and apoptosis, all well-known pathomechanisms of Parkinson's disease (PD). Melatonin is a potent antioxidant that has the beneficial ability to prevent neurodegenerative diseases like PD. We aimed to explore the protective properties of melatonin in an in vitro PD model, focusing on its underlying mechanism u...

Molecules, Vol. 27, Pages 4350: Melatonin Reverses the Warburg-Type Metabolism and Reduces Mitochondrial Membrane Potential of Ovarian Cancer Cells Independent of MT1 Receptor Activation
ustavo de Almeida Chuffa
Ovarian cancer (OC) is the most lethal gynecologic malignancy, and melatonin has shown various antitumor properties. Herein, we investigated the influence of melatonin therapy on energy metabolism and mitochondrial integrity in SKOV-3 cells and tested whether its effects depended on MT1 receptor activation. SKOV-3 cells were exposed to different melatonin concentrations, and experimental groups were divided as to the presence of MT1 receptors (melatonin groups) or receptor absence by RNAi silencing (siRNA MT1+melatonin). Intracellular melatonin levels increased after treatment with melatonin in...

Melatonin inhibits angiotensin II-induced atrial fibrillation through preventing degradation of Ang II Type I Receptor-Associated Protein (ATRAP)
In this study, Ang II was used to induce AF, and AF inducibility and duration were documented telemetrically. Ang II-infused mice had a higher AF incidence, which was associated with atrial fibrosis, inflammation, and oxidative stress. Melatonin partially inhibited these effects, and enforced expression of siRNA-ATRAP in atria counteracted the beneficial role of melatonin. Specifically, melatonin inhibited expression of Ang II-induced proteasome and immunoproteasome subunits β2, β2i, β5, and β5i as well as their corresponding trypsin-like and chymotrypsin-like activities and blocked ATRAP degradation. In turn, this inh...

Melatonin Inhibits OGD/R-Induced H9c2 Cardiomyocyte Pyroptosis via Regulation of MT2/miR-155/FOXO3a/ARC Axis
Int Heart J. 2022;63(2):327-337. doi: 10.1536/ihj.21-571.ABSTRACTEmerging literature suggests that pyroptosis plays a critical role in ischemia/hypoxia (I/R) -induced myocardial injury. Melatonin has been implicated in attenuating I/R-induced injury of cardiomyocytes. Nevertheless, whether melatonin inhibits I/R-induced pyroptosis of cardiomyocytes and the underlying molecular mechanisms remain unexploited.H9c2 cardiomyocytes were cultured under oxygen-glucose deprivation/reperfusion (OGD/R) condition to establish a myocardial pyroptosis model in vitro. OGD/R-induced pyroptosis was evaluated by CCK-8 assay, IL-1β and IL-1...
