CHD4 and endometrial carcinoma: CHD4 has been identified as a tumor suppressor and regulator of stemness in human endometrial carcinoma cell lines, but little is known about the tissue-specific roles of CHD4 in the endometrial epithelia in vivo. We generated a conditional Chd4 floxed allele and combined it with BAC-Sprr2f-Cre to drive CHD4 loss in the endometrial epithelium.
