Modulated Autophagy by MicroRNAs in Osteoarthritis Chondrocytes

Abstract EN

Osteoarthritis (OA) is a chronic joint disease characterized by articular cartilage regression.

The etiology of OA is diverse, the exact pathogenesis of which remains unclear.

Autophagy is a conserved maintenance mechanism in eukaryotic cells.

Dysfunction of chondrocyte autophagy is regarded as a crucial pathogenesis of cartilage degradation in OA.

MircoRNAs (miRNAs) are a category of small noncoding RNAs, acting as posttranscriptional modulators that regulate biological processes and cell signaling pathways via target genes.

A series of miRNAs are involved in the progression of chondrocyte autophagy and are connected with numerous factors and pathways.

This article focuses on the mechanisms of chondrocyte autophagy in OA and reviews the role of miRNA in their modulation.

Potentially relevant miRNAs are also discussed in order to provide new directions for future research and improve our understanding of the autophagic network of miRNAs.
