WebThe most potent androgen is dihydrotestosterone (DHT), which is formed in the target cells, i.e. in the sebaceous glands, by a 5 alpha-reduction of testosterone. DHT is then bound to a specific receptor protein and translocated into the cell nucleus. In young persons genetically predisposed to acne a temporarily increased local DHT-formation ... WebCuriously, early studies demonstrated that intratumoral 5α-dihydrotestosterone , the most potent endogenous androgen, declined modestly despite the dramatic reductions in circulating T during ADT . This paradox was the first suggestion that CRPC tumor cells have the capacity to synthesize androgens; however, which androgens, how much, and from ...
