Encoding and decoding photoperiod in the mammalian pars tuberalis.
In mammals, the nocturnal melatonin signal is well established as a key hormonal indicator of seasonal changes in day-length, providing the brain with an internal representation of the external photoperiod. The pars tuberalis (PT) of the pituitary gland is the major site of expression of the G-coupled receptor MT1 in the brain and is considered as the main site of integration of the photoperiod...
متن کاملBovine pars tuberalis secretions release growth hormone from rat pars distalis of pituitary gland.
UNLABELLED The pituitary pars tuberalis (PT) is characterized by PT-specific secretory cells which have raised the possibility of an endocrine function for this portion of adenohypophysis. OBJECTIVE To investigate the effect of the secretion of bovine PT cells into culture medium on growth hormone (GH) response of dispersed pars distalis (PD) cells of rats. METHODS AND RESULTS 48-hour cultu...
متن کاملMultiple effects of melatonin on rhythmic clock gene expression in the mammalian pars tuberalis.
In mammals, changing day length modulates endocrine rhythms via nocturnal melatonin secretion. Studies of the pituitary pars tuberalis (PT) suggest that melatonin-regulated clock gene expression is critical to this process. Here, we considered whether clock gene rhythms continue in the PT in the absence of melatonin and whether the effects of melatonin on the expression of these genes are tempo...
متن کاملthe relationship between iranian efl learners multiple intelligences and their reading comprehension ability
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
15 صفحه اولA 66-kDa protein of bovine hypophyseal Pars tuberalis induces luteinizing hormone release from rat Pars distalis.
In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total ce...
