Interestingly, XIAP was significantly decreased in RCC (Fig. 3); increased XIAP expression in ccRCC tumors is significantly associated with better ccRCC patient survival (Fig. 4A), while there is no significant difference for chRCC and pRCC patients’ survival with XIAP expression levels (Fig. 4BC). The gene discussed is XIAP; the disease is chromophobe renal cell carcinoma.
