We confirmed expression of NQO1 (Figure 1E), the NQO1 target p53 and another exemplar gene identified by RNAseq, GJB2, (Figure S1) was significantly increased (P < .05) in endometrial specimens from women with PCOS (n = 25) and EC (n = 25) as compared to control, unaffected women (n = 25). Here, TP53 is linked to polycystic ovary syndrome.
