NQO1 and endometrial carcinoma: On the other hand, NQO1 regulation may involve other transcriptional factors and its low expression in a subset of endometrial carcinomas might be related to biological processes independent of NRF2: an extensive chromatin and transcriptomic analysis of these tumors would be required to determine whether NRF2 transcriptional program is indeed skewed in TP53 mutated serous tumors.
