LDHA and ovarian cancer: While the inhibition of ALDH has been studied in breast, cervical, and ovarian cancers using all-trans retinoic acid (ATRA), N,N-diethylaminobenzaldehyde (DEAB), and JQ1 [17,21,22,23], to the best of our knowledge, the topic of ALDH inhibition in endometrial CSCs remains understudied [24].
