Aquaporin 1 contributes to chondrocyte apoptosis in a rat model of osteoarthritis.

ABSTRACT: Aquaporins (AQPs) have been found to be associated with a number of diseases. However, the role of AQP‑1 in the pathogenesis of osteoarthritis remains unclear. We previously found that AQP‑1 expression was upregulated in osteoarthritic cartilage and strongly correlated with caspase‑3 expression and activity. The aim of this study was to further investigate the association of AQP‑1 expression with chondrocyte apoptosis in a rat model of osteoarthritis, using RNA interference to knock down AQP‑1. For this purspose, 72 male Sprague‑Dawley rats were randomly assigned to 3 groups as follows: the control group not treated surgically (n=24), the sham‑operated group (n=24), and the osteoarthritis group (n=24). Osteoarthritis was induced by amputating the anterior cruciate ligament and medial colla
