Decreased miR-214-3p activates NF-κB pathway and aggravates osteoarthritis progression.

ABSTRACT:

Background

Osteoarthritis (OA), a disease with whole-joint damage and dysfunction, is the leading cause of disability worldwide. The progressive loss of hyaline cartilage extracellular matrix (ECM) is considered as its hallmark, but its exact pathogenesis needs to be further clarified. MicroRNA(miRNA) contributes to OA pathology and may help to identify novel biomarkers and therapies against OA. Here we identified miR-214-3p as an important regulator of OA.

Methods

qRT-PCR and in situ hybridization were used to detect the expression level of miR-214-3p. The function of miR-214-3p in OA, as well as the interaction between miR-214-3p and its downstream mRNA target (IKBKB), was evaluated by western blotting, immunofluorescence, qRT-PCR and luciferase assay. Mice models were int
