Thirty-six pyroptosis genes exhibited significantly higher transcriptional levels in HCC, including APIP, BAK1, BAX, CASP3, CASP4, CASP6, CASP8, CASP9, CHMP2A, CHMP2B, CHMP3, CHMP4A, CHMP4B, CHMP4C, CHMP6, CHMP7, CYCS, DFNA5, DHX9, GPX4, GSDMB, GSDMC, GSDMD, HMGB1, IL1A, IRF2, NLBP1, NLRP9, NOD1, NOD2, PLCG1, PRKACA, PYCARD, SCAF11, TIRAP, and TP53. This evidence concerns the gene CHMP7 and hepatocellular carcinoma.
