ssGSEA analysis showed that compared with HCC_SNRPB_High cell subset, HCC_SNRPB_Low cell subset had higher ferroptosis and oxidative stress scores and lower cell cycle scores (p < 0.001) (Figure 4K–4M), which further indicate that downregulation of SNRPB may promote HCC cell death by inducing oxidative stress and ferroptosis, while upregulation of SNRPB may promote HCC progression by affecting cell cycle. The gene discussed is SNRPB; the disease is hepatocellular carcinoma.
