Abstract
The pesticide o,p'-DDT stimulates the production of a specific uterine protein, the so-called induced protein or IP, normally associated with an estrogenic response of the uterus. Invivo stimulation of IP production is observed 1 hour after the administration of 250 mg/kg of o,p'-DDT to immature rats. Invitro stimulation of IP production is observed after a 1 hour incubation of uteri with 100 μM o,p'-DDT. This invitro response is blocked by Actinomycin D. In contrast to o,p'-DDT, which binds to the cytoplasmic estrogen receptor and stimulates IP production, p,p'-DDT which does not bind well to the estrogen receptor does not stimulate IP production invitro. These findings represent the first report of an estrogenic effect of o,p'-DDT in a completely invitro system.
