UBQLN4 and colorectal carcinoma: Then, we evaluated the prognostic value of UBQLN4 in CRC patients using Kaplan–Meier analysis and the log-rank test, and patients with high UBQLN4 expression experienced shorter survival (overall survival, p = 0.002, Fig. 1H, disease-free survival, DFS, p = 0.002, Fig. 1I).
