Yoshihara (Peritoneum (n = 10) ovarian serous adenocarcinoma (n = 43)), Tothill (ovarian surface epithelial-stromal tumour (n = 18) ovarian carcinoma (n = 171)), Anglesio (ovarian surface epithelial-stromal tumour (n = 30) ovarian carcinoma (n = 44)) and Lu ovarian (ovarian surface epithelium (n = 5) ovarian serous adenocarcinoma (n = 20)) dataset analysis indicated that PDK1 mRNA expression is up-regulated in ovarian carcinoma (Supplementary Figure S6). Here, PDK1 is linked to ovarian serous adenocarcinoma.
