PKP1 and ovarian carcinoma: We further detected the correlations of PKP1/2/3 with OS and PFS in ovarian cancer patients with TP53 mutation, the results showed that high expression of PKP1 had poor OS [HR = 1.28 (1.01–1.63), log-rank P = 0.044] and PFS [HR = 1.41(1.11–1.79), log-rank P = 0.0045] in TP53 mutated ovarian cancer patients (Fig. 2B (g) and Fig. 2B (j)) (Additional file 1: Table S2).
