The results suggested that 19 necroptosis related genes (CASP8, HSP90AA1, RNF31, NR2C2, HSPA4, USP22, TNFRSF21, SLC39A7, TSC1, SQSTM1, TRIM11, TRAF2, DNMT1, EZH2, LEF1, PLK1, MYCN, CDKN2A, and TERT) were upregulated while 3 necroptosis related genes (ID1, ALDH2, and BACH2) were downregulated in HCC versus paired non-tumor tissues (|log2FC|>1 and adjusted P <0.05) (Supplementary Table 3). The gene discussed is HSP90AA1; the disease is neoplasm.
