Abstract:
:The effect of dehydroepiandrosterone (DHEA) (2 mg, twice daily p.o.) on the growth of the dimethylbenz (a) anthracene (DMBA)-induced mammary carcinoma was studied in intact and ovariectomized adult female rats. DHEA treatment stimulated the tumor growth in ovariectomized animals. Conversely, the tumors of intact rats treated with DHEA progressed to a lesser extent than those of intact untreated animals (p < 0.01). Plasma levels of DHEA were higher in DHEA-fed than in untreated animals (p < .01), whereas E2 concentrations were unchanged after DHEA administration. Estrogen receptor (ER) concentrations in tumor tissue of ovariectomized animals given DHEA were no different form those found in intact rats, whereas ER were undetectable in untreated ovariectomized rats. The data indicate that DHEA stimulates the growth of DMBA-induced mammary tumors in ovariectomized rats, while it reduces the tumor progression in intact animals.
