Figure 1From: Effects of hypoxia on anabolic and catabolic gene expression and DNA methylation in OA chondrocytes Relative expression of IL1B (A), MMP13 (B) and COL9A1 (C) in articular OA chondrocytes under normoxic versus hypoxic conditions analysed by qRT-PCR. Values are the mean ± SD of triplicate determinations per sample (n = 5; *p < 0.1; **p < 0.05).Back to article page
