In this study, thirteen potential target genes of celastrol in RA have been identified, including ADAMTS5, AGTR1, ALOX5, CTSB, MMP3, MMP9, MYC, TNF, ITGA4, ITGB7, MMP1, MMP13, and PPARG. Among these, ALOX5 was found to significantly promote MMP3 protein expression, based on which a regulatory model with high predictive power was constructed. The gene discussed is AGTR1; the disease is rheumatoid arthritis.
