USP5 and nasopharyngeal carcinoma: We further performed IHC staining in a cohort of 230 NPC samples and dichotomized the patients into a high or low USP5 expression group (Supplemental Table 2) for Kaplan-Meier analysis, which revealed that the patients with high USP5 expression had shorter overall, disease-free, and distant metastasis–free survival rates (Figure 1O and Supplemental Figure 2H).
