MicroRNA-181a/b-1 enhances chondroprogenitor anabolism and downregulates aquaporin-9.

ABSTRACT:

Objective

Effective osteoarthritis treatments that enhance the anabolic/regenerative capacity of chondrocytes are needed. Studying cartilage development processes may inform us of approaches to control chondrocyte differentiation and anabolism and, ultimately, how to effectively treat OA. MicroRNAs are broad-acting epigenetic regulators known to affect many skeletal processes. Previous reports from our group indicated that miR-181a-1 is upregulated during chondrocyte differentiation. The goal of this study was to determine how the entire miR-181a/b-1 cluster regulates in vitro chondrogenesis.

Design

Precursor miR-181a/b-1 was over-expressed in cartilage progenitor cells using lentiviral technology Transduced cartilage progenitor cells were cultured as micromass pellet
