Moreover several YAP associated genes are also upregulated in undifferentiated arthritis - MOB1A (p < 0.001), MOB1B (p < 0.0001), DCP-2 (p < 0.01), and LATS1 (p < 0.0001), early RA - MOB1A (p < 0.0001), MOB1B (p < 0.0001), DCP-2 (p < 0.0001), LATS1 (p < 0.0001), and STK4 (p < 0.0001), and established RA - MOB1A, (p < 0.0001), MOB1B (p < 0.0001), DCP-2 (p < 0.0001), LATS1 (p < 0.0001), and STK4 (p < 0.0001) (Supplementary Figure 5). Here, STK4 is linked to rheumatoid arthritis.
