Interestingly, low mRNA expression of RELA showed a trend toward poor prognosis in all HCC patients (HR = 0.84) (Figure S3A, Supporting Information) and was significantly associated with worse outcomes in early‐stage patients or those with high differentiation (Grade 2, HR = 0.53; Grade 2 and Stage 1 + 2, HR = 0.29) (Figure 2A). Here, RELA is linked to hepatocellular carcinoma.
