Dehidroepiandrosteron (DHEA, Fidelin, androstenolon, prasteron, 3β-hidroksiandrost-5-en-17-on, 5-androsten-3β-ol-17-on) je važan endogeni steroidni hormon.^[5] On je najzastupljeniji circulišući steroid kod ljudi,^[6] kod kojih ga proizvode nadbubrežne žlezde,^[7] gonade, i mozak,^[8] gde on predominentno funkcioniše kao metabolički intermedijer u biosintezi androgena i estrogena seksualnih steroida.^[9]^[5] Međutim, DHEA takođe ima raznovrsne samostalne potencijalne biološke efekte. On se vezuje za niz nuklearnih površinskih receptora,^[10] i deluje kao neurosteroid.^[11]

Kancer[uredi | uredi kod]

Više in vitro studija je utvrdilo da DHEA ima antiproliferativne i apoptozne efekte na ćelijama kancera.^[12]^[13]^[14] Kliničkih značaj tih nalaza nije poznat. Visoki nivoi DHEA i drughi endogenih seks hormona su u znatnoj meri vezani za povišeni rizik od razvoja raka dojki pre- i postmenopozalno.^[15]^[16]
