Fig. 1From: A long non-coding RNA, HOTAIR, promotes cartilage degradation in osteoarthritis by inhibiting WIF-1 expression and activating Wnt pathwayExpression levels of (a) HOTAIR and (b) OA-related genes in chondrocytes isolated from normal and OA cartilage (n = 10). Relative mRNA expression is determined by real-time qRT-PCR and normalised to GAPDH. The OA group is expressed as a fold difference from the normal group. *P < 0.05Back to article page
