The 169 identified proteins were enriched (Supplementary Table 9) in cytokine receptor interaction (P = 6.0×10−10), chemokine receptor binding (P = 1.4×10−7), PI3K-Akt signaling (P = 5.7×10−4) as well as targets of known TFs involved in RCC like c-JUN (P = 8.6×10−6) and c-FOS (P = 2.8×10−3). Here, JUN is linked to renal cell carcinoma.
