... messengers relate to functional properties of behavior-controlling neurons. This problem was investigated in the roughskin newt, Taricha granulosa , an amphibian in which the administration of arginine vasotocin (AVT) facilitates and corticosterone (CORT) inhibits courtship clasping of females by males...

... Amphibians Abstract. The distribution of immunoreactive corticotropin-releasing hormone (CRF) in the forebrain and pituitary of the frog Rana ridibunda was studied by means of specific radioimmunoassay and immunohistochemistry using the indirect immunofluorescence and the peroxidase-antiperoxidase techniques...

...Stewart P. Mennin; Linda C. Saland Pituitary intermediate lobe melanocyte-stimulating hormone (MSH) is responsible for normal skin darkening in amphibians. Light-background adapted frogs ( Rana pipiens ) injected with naloxone and placed on black backgrounds maintain melanophore indices...

... only been described in a limited number of species, we were interested in identifying neuroserpin in our model system, the amphibian X. laevis . To this end, we performed RT-PCR and amplified, cloned and sequenced a specific product of 1,248 bp. Alignment of the deduced amino acid sequence...

...HongYan Zhang; Bruce G. Jenks; Alessandro Ciccarelli; Eric W. Roubos; Wim J.J.M. Scheenen Dopamine inhibits pituitary melanotrope cells of the amphibian Xenopus laevis through activation of a dopamine (D 2 ) receptor that couples to a G i protein. Activated G i protein subunits are known to affect...

.... Amphibians Reptiles Catecholamines Intermediate lobe Melanocyte-stimulating hormone A model was developed for the mechanisms of control of the secretion and release of melanocyte-stimulating hormone (MSH) from the pars intermedia (PI) of the pituitary [ 1 ]. Stated in that review is the fact...

... in the regulation of exocytosis efficiency, using neuroendocrine melanotrope cells of the amphibian Xenopus laevis . Exocytosis efficiency was determined by membrane capacitance measurements. Mimicking the bursting activity of 1 Hz (typical for this cell type) by repetitive depolarizing pulses enhanced exocytosis...

..., and none in amphibians. We examined the effects of testosterone (T) and dihydrotestosterone (DHT) on changes in tyrosine hydroxylase immunoreactive (TH-ir) neuron number in the fore- and midbrain of male Rana pipiens , the Northern leopard frog, using a whole-mount immunohistochemical procedure...

... of its acetylation, as well as the POMC mRNA content in the LD subpopulation, whereas it does not exert such effects on HD cells [ 7 ]. These results indicated that the frog hypothalamus may differentially control these melanotrope subpopulations. In fact, amphibian melanotrope cells are directly...

With respect to the fragment of S. multiplicatus proenkephalin cDNA, two metenkephalin sequences and the metenkephalin-RF sequence were found encoded in this fragment. As seen for X. laevis and R. ridibunda proenkephalin, a leuenkephalin sequence was not detected...
