UBE4B and cancer: The GEPIA database was used to elucidate the relationship between UBE4B expression and pathological stages in different cancers, revealing significant correlations between UBE4B expression and pathological stages of COAD (P = 0.00308), KIRC (P = 8.01 × 10-5), LIHC (P = 0.00739), and OV (P = 0.0233) (Figure 2A).
