We examined PAX8 expression in 22 different types of cancer using TNMPLOT online software (https://tnmplot.com/analysis/) [11] and found relatively high PAX8 mRNA levels in uterine corpus endometrial carcinoma (UECE), uterine carcinosarcoma (UCS) and ovarian serous cystadenocarcinoma (OSC) (Fig. 1A–C and Supplementary Fig. 1). The gene discussed is PAX8; the disease is uterine carcinosarcoma.
