Expression levels of caspase-3, survivin and xIAP mRNAs in inactive RA, active RA and OA patients. These levels were determined by real-time PCR. The results are normalised to levels of hARP and have been expressed relative to OA control tissue. *p < 0.05, compared with inactive RA. n = 3 (OA), n = 3 (inactive RA), n = 5 (active RA). OA = osteoarthritis; PCR = polymerase chain reaction; RA = rheumatoid arthritis; xIAP = x-linked inhibitor of apoptosis protein.
