MiR-129-5p Protects H9c2 Cardiac Myoblasts From Hypoxia/Reoxygenation Injury by Targeting TRPM7 and Inhibiting NLRP3 Inflammasome Activation.

J Cardiovasc Pharmacol 2021 May;77(5):586-593

Department of Cardiology, Northern Jiangsu People's Hospital, Yangzhou, Jiangsu, China.

Abstract: As a biomarker for heart failure, miR-129-5p is abnormally expressed during myocardial I/R, but its specific functions and mechanisms remain largely unclear. Thus, this study explored the roles and possible mechanisms of miR-129-5p in hypoxia/reoxygenation (H/R)-insulted H9c2 cardiac myoblasts. After H/R insult, miR-129-5p expression levels were decreased, along with reduced cell viability and enhanced lactate dehydrogenase release in H9c2 cells. Read More

Physical tuning of galectin-3 signaling.

Proc Natl Acad Sci U S A 2021 May;118(19)

J. Crayton Pruitt Family Department of Biomedical Engineering, University of Florida, Gainesville, FL 32611

Galectin-3 (Gal3) exhibits dynamic oligomerization and promiscuous binding, which can lead to concomitant activation of synergistic, antagonistic, or noncooperative signaling pathways that alter cell behavior. Conferring signaling pathway selectivity through mutations in the Gal3-glycan binding interface is challenged by the abundance of common carbohydrate types found on many membrane glycoproteins. Here, employing alpha-helical coiled-coils as scaffolds to create synthetic Gal3 constructs with defined valency, we demonstrate that oligomerization can physically regulate extracellular signaling activity of Gal3.

Insulin resistance and liver histopathology in metabolically unhealthy subjects do not correlate with the hepatic abundance of NLRP3 inflammasome nor circulating IL-1β levels.

BMJ Open Diabetes Res Care 2021 May;9(1)

Department Nutrition, Diabetes and Metabolism, Faculty of Medicine, Pontifical Catholic University of Chile, Santiago, Chile

Introduction: Systemic chronic low-grade inflammation has been linked to insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). NOD-like receptor protein 3 (NLRP3) inflammasome and its final product, interleukin (IL)-1β, exert detrimental effects on insulin sensitivity and promote liver inflammation in murine models. Evidence linking hepatic NLRP3 inflammasome, systemic IR and NASH has been scarcely explored in humans. Read More

Caspase activity in post mortem muscle and its relation to cattle handling practices.

J Sci Food Agric 2021 May 3. Epub 2021 May 3.

Instituto de Agroquímica y Tecnología de Alimentos (CSIC), 46980, Paterna-Valencia, Spain.

Background: Animal handling practices are one of the factors majorly affecting animal metabolism prior to slaughter. This phenomenon increases the occurrence of meat quality defects such as dark cutting-beef, causing high economical losses in the meat industry. Under this framework, the assessment of apoptosis onset in post mortem muscle was proposed as a novel approach to reveal biochemical characteristics in several Spanish bovine breeds (Asturiana de los Valles, Retinta and Rubia Gallega) managed under different production systems (intensive vs semi-extensive) and transport/lairage conditions (mixing vs not mixing with unfamiliar animals).

TRIM21, a New Component of the TRAIL-Induced Endogenous Necrosome Complex.

Front Mol Biosci 2021 15;8:645134. Epub 2021 Apr 15.

Univ-Rennes1, Inserm, EHESP, Irset (Institut de recherche en santé, environnement et travail) - UMR_S1085, Rennes, France.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a well-known apoptosis inducer and a potential anticancer agent. When caspases and inhibitors of apoptosis proteins (IAPs) are inhibited, TRAIL induces necroptosis. Molecular mechanisms of necroptosis rely on kinase activation, and on the formation of a necrosome complex, bringing together the receptor-interacting protein kinases 1 and 3 (RIPK1, RIPK3), and the mixed lineage kinase domain-like protein (MLKL).
