Tanycytes As Regulators of Seasonal Cycles in Neuroendocrine Function
Annual cycles of physiology and behavior are highly prevalent in organisms inhabiting temperate and polar regions. Examples in mammals include changes in appetite and body fat composition, hibernation and torpor, growth of antlers, pelage and horns, and seasonal reproduction. The timing of these seasonal cycles reflects an interaction of changing environmental signals, such as daylength, and in...
متن کاملNTPDases in the neuroendocrine hypothalamus: Possible energy regulators of the positive gonadotrophin feedback
BACKGROUND Brain-derived ectonucleoside triphosphate diphosphohydrolases (NTPDases) have been known as plasma membrane-incorporated enzymes with their ATP-hydrolyzing domain outside of the cell. As such, these enzymes are thought to regulate purinergic intercellular signaling by hydrolyzing ATP to ADP-AMP, thus regulating the availability of specific ligands for various P2X and P2Y purinergic r...
متن کاملChromogranin A and Its Fragments as Regulators of Small Intestinal Neuroendocrine Neoplasm Proliferation
INTRODUCTION Chromogranin A is a neuroendocrine secretory product and its loss is a feature of malignant NEN de-differentiation. We hypothesized that chromogranin A fragments were differentially expressed during NEN metastasis and played a role in the regulation of NEN proliferation. METHODS Chromogranin A mRNA (PCR) and protein (ELISA/western blot) were studied in 10 normal human mucosa, 5 e...
متن کاملEffects of weaning and weaning weight on neuroendocrine regulators of feed intake in pigs.
A depression in feed intake and growth often occurs in the weaned pig. Spray-dried plasma is often added to nursery diets in an attempt to stimulate feed intake during this lag. The current study evaluated gene expression of appetite regulators in hypothalamus and adipose tissue 4 d after weaning. Barrows (2 wk of age) were cross-fostered to a sow (SOW, n = 8) or weaned and fed a nursery diet c...
متن کاملThe diabetes autoantigen ICA69 and its Caenorhabditis elegans homologue, ric-19, are conserved regulators of neuroendocrine secretion.
ICA69 is a diabetes autoantigen with no homologue of known function. Given that most diabetes autoantigens are associated with neuroendocrine secretory vesicles, we sought to determine if this is also the case for ICA69 and whether this protein participates in the process of neuroendocrine secretion. Western blot analysis of ICA69 tissue distribution in the mouse revealed a correlation between ...
