In contrast, the cues that determine the progression of the various anterior pituitary cell types during postnatal periods are poorly defined. Pax8-/-mice, which are born without a thyroid gland, were used to study the influence of thyroid hormones on the expression of pituitary hormones during early postnatal life. Serum pituitary hormones were determined by RIAs, and the pituitaries were analyzed by Northern blotting, in situ hybridization histochemistry, and immunocytochemistry. In 21-d-old Pax8-/-mice, the cellular composition of the anterior pituitary was dramatically distorted. Thyrotropes exhibited hypertrophy and hyperplasia, the number of detectable somatotropes was drastically reduced, and lactotropes were almost undetectable. Expression of LH and FSH was also reduced, but ACTH and proopiomelanocortin expression was not significantly different. Serum pituitary hormone levels were changed correspondingly. T(4) replacement therapy for variable time periods normalized TSH and GH mRNA expression within 3 d but not prolactin expression, not even when T(4) was administered for 6 d in combination with estradiol. These findings reveal the importance of thyroid hormones in developing the appropriate proportions of anterior pituitary cell types, especially with regard to lactotropes."xsd:string |
