IL17A and rheumatoid arthritis: As displayed in Figures 5D,E, patients in the high-risk group were significantly enriched in invasive- and developmental-related pathways, such as cartilage development, muscle cell differentiation, regulation of cartilage development, basal cell carcinoma, calcium signaling pathway et al. In contrast, patients in the high-risk group were significantly enriched in repair- and inflammatory-related pathways, such as IL-17 signaling pathway, rheumatoid arthritis, recombinational repair, meiotic cell cycle process et al. (Figures 5F,G).
