Research Abstract |
Pin1 expression was significantly higher in RA-ST than in OA-ST. The expression of MMP-1, MMP-3, and PCNA was also significantly elevated in RA-ST. Double immunofluorescent staining revealed colo-calization of Pin1 and p65 in the nuclei of RA-ST. Positive correlation with Pin1 and C/EBP-β(a transcription factor of IL6)was also indicated. These results suggest that Pin1 may be involved in the pathogenesis of RA binding with p65 to activate the proteins MMP-1, MMP-3, and PCNA. Therefore, Pin1 may play a pivotal role in the pathogenesis of RA.
