Specifically, 32 genes were up-regulated (GZMA, AIM2, CASP5, GZMB, NOD2, NLRP7, GSDMC, PYCARD, GSDMB, NLRC4, CASP1, NLRP6, GSDMA, NLRP3, CASP4, NLRP1, BAX, IRF1, CHMP4A, L18, CASP8, GSDMD, NOD1, PLCG1, CASP3, GPX4, TP53, CHMP6, CHMP2A, IRF2, CHMP4B, HMGB1) and 9 genes were down-regulated (IL1B, CHMP3, CHMP4C, CHMP2B, IL1A, CASP9, CYCS, TP63, NLRP2) in ccRCC tissues. The gene discussed is HMGB1; the disease is nonpapillary renal cell carcinoma.
