PECAM1 and rheumatoid arthritis: The results of GSVA showed that the immune response to tuberculosis, PECAM1 interactions, and other identified top 20 pathways were statistically significant in IBD (p < 0.05) (Figure 5A), whereas the folding of actin by CCT tric, the biocarta proteasome pathway, and other identified top 20 pathways were significantly different in RA (p < 0.05) (Figure 5B).
