Abstract

Anterior pituitary tumors were induced in F344 rats by implants of diethylstilbesterol (DES) for 8 weeks. DES-induced tumors contained 250 times more glandular kallikrein than anterior pituitaries from rats not exposed to estrogen, and 6.6 times more glandular kallikrein than anterior pituitaries from rats exposed to large doses of estrogen for 10 days. DES-induced anterior pituitary tumors in F344 rats arise from lactotroph proliferation. Thus, the results suggest that anterior pituitary glandular kallikrein is associated with lactotrophs.

摘要

通过植入己烯雌酚(DES)8周诱导F344大鼠发生垂体前叶肿瘤。DES诱导的肿瘤所含的腺体激肽释放酶比未接触雌激素的大鼠垂体前叶多250倍,比接触大剂量雌激素10天的大鼠垂体前叶多6.6倍。F344大鼠中DES诱导的垂体前叶肿瘤源于催乳素细胞增殖。因此,结果表明垂体前叶腺体激肽释放酶与催乳素细胞有关。
