Expression in the cartilage of 32 OA patients of BCL2L13, BID and MICAL3 stratified by genotype at the OA associated SNP rs2277831. The data points represent the average of the three replicates for each sample. The expression of (A) BCL2L13, (B) BID and (C) MICAL3 was compared to the average of the housekeeping genes and the delta Ct values were plotted against the genotype at the associated SNP rs2277831. The horizontal bars represent the mean plus the standard deviation. The genotype at rs2277831 did not correlate with gene expression with P-values of 0.09 for BCL2L13, 0.07 for BID and 0.33 for MICAL3.
