ZDHHC15 and ovarian carcinoma: Kaplan‐Meier survival analyses showed that elevated ZDHHC15 mRNA levels significantly correlated with worse survival in patients with either breast cancer (Figure 4H, n = 481; grade III; P = 0.029) or ovarian cancer (Figure S12A, Supporting Information n = 614; P = 0.003), suggesting that ZDHHC15 is a significant prognostic factor in breast and ovarian cancers.
