PSMD4 and hepatocellular carcinoma: Although low MCB1 (cohort 1, Figure S1F, Supporting Information) or high p53 (cohort 1, Figure S5Q, Supporting Information) in HCC predicts a good prognosis, HCC patients with both reduced MCB1 levels and elevated p53 expression displayed an even better prognosis (cohort 1, Figure 3M), suggesting an improved prognostic value of the combination of MCB1 and p53.
