... and species. This microarray study investigated the effects of aging, long-term moderate caloric restriction (LTMCR) and long-term dietary soy on the regulation of gene expression in the anterior pituitary and hypothalamus of 20-month-old Sprague-Dawley rats. In both tissues, aging regulated genes mainly...

... in the discontinuous ethanol group. Conclusions: Abstinence after discontinuous drinking of alcohol in rats, as compared to chronic administration of ethanol, is accompanied by increases of plasma LH and testosterone, a greater PRL response and a less pronounced oxidative damage of the anterior pituitary...

... of a suspension of dispersed rat anterior pituitary cells resulted in the rapid (within 1 h) selection of cells possessing D2 DA receptors (i.e. lactotrophs). Four-fold enrichment (from about 20% in the suspension to about 80%) was routinely obtained, as judged by prolactin (PRL) immunostaining. The enriched...

...Gérard Morel; Allal Ouhtit; Paul A. Kelly Prolactin (PRL) receptors have been identified in both classical and nonclassical target organs. Actions of PRL on the secretion of anterior pituitary hormones have been reported. In order to confirm the presence of PRL receptors on specific cell types...

...Mieczyslaw Michalkiewicz; Mitsuo Suzuki We examined whether hypothyroidism-induced increases in the anterior pituitary content of vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) are mediated by the hypothalamus. Male Sprague-Dawley rats were anesthetized and one of the following...

...Gong Ju; Dan Ma; Si-Chang Fan The mammalian anterior pituitary is known to be regulated by humoral factors only, no direct neural influence having ever been discovered. Our recent studies have shown in several species that there are substantial amounts of substance P and calcitonin-gene-related...
