Moreover, the expression of TIPE1 was positively correlated with that of the proliferation marker Ki67 (r = 0.2835, P = .019) (Figure 1B and D), and the expression of TIPE1 in the NPC tissue samples was negatively correlated with the overall survival rate of the patients (P = .039) (Figure 1E). Here, MKI67 is linked to nasopharyngeal carcinoma.
