Summary of "miRNA-335-5p relieves chondrocyte inflammation by activating autophagy in osteoarthritis."

Osteoarthritis (OA) is a chronic and degenerative joint disease prevalent in the elderly, which is characterized by hypertrophy and reactive hyperplasia of articular cartilage. Autophagy has been reported to inhibit inflammation and reduce chondrocyte apoptosis in OA. As the microRNA (miRNA)-335-5p has been linked to both inflammation and autophagy, this study aimed to investigate its potential role in regulating autophagy during the pathogenesis of OA.

Medical and Biotech [MESH] Definitions

An autophagy related protein that is similar to UBIQUITIN-ACTIVATING ENZYME E1. It functions in CYTOPLASM to VACUOLE transport (Cvt) and AUTOPHAGY by activating ATG12 PROTEIN for its conjugation with ATG5 PROTEIN, as well as the conjugation of ATG8 FAMILY PROTEINS with phosphatidylethanolamine for ATG8 association to Cvt vesicles and AUTOPHAGOSOME membranes. It is also required for the nitrogen starvation response in yeast, MITOPHAGY; and autophagic cell death induced by CASPASE 8 inhibition.

Proteins and enzymes that function, often as components of MULTIPROTEIN COMPLEXES, to assemble AUTOPHAGOSOMES and carry out AUTOPHAGY.

A volatile vasodilator which relieves ANGINA PECTORIS by stimulating GUANYLATE CYCLASE and lowering cytosolic calcium. It is also sometimes used for TOCOLYSIS and explosives.

Chemically-engineered oligonucleotides used to selectively inhibit expression of target genes through sequence-specific binding of corresponding microRNA (miRNA) sites.

A serine/threonine-protein kinase that functions in AUTOPHAGY in response to starvation. It acts on the PHOSPHATIDYLINOSITOL 3-KINASE complex PIK3C3 to regulate AUTOPHAGOSOME formation. It also functions as both a downstream effector and negative regulator of mammalian target of rapamycin complex 1 (mTORC1) and is activated by AMPK, which it also negatively regulates.
