NQO1 and carcinoma: Finally, because of the histopathological heterogeneity of the TP53/CNH-like molecular group, which includes type II carcinomas (N = 13, 56.5%), and also type I endometrial carcinomas (N = 9, 40.1%), we wondered whether a low NQO1 mRNA level could be related to the histological type or estrogen receptor positivity.
