1 Gonadotropin - Releasing Hormones : Why Do Fish Need Multiple Forms ?
Vertebrate skeletal muscles contain muscle fibers of several types, which can be broadly classified as slow or fast fibers, on the basis of differences in contraction speeds, metabolic activities, and motoneuron innervation. We have examined the potential roles of growth factors of members of the hedgehog and TGF-ß gene families in the formation of slow muscle fibers including muscle pioneer (M...
متن کاملGonadotropin-releasing hormones and Psychosis
Background: There have been reports of transient psychosis in women medicated for gynecologic conditions.Objective: The aim of this paper was to explore this literature.Method: The PubMed and Google Scholar databases were searched for relevant case reports Results: The following reports were found: psychosis induced by gonadotropinreleasing hormone in the treatment of endometriosis, by clomiphe...
متن کاملGonadotropin-releasing hormones in the brain and pituitary of the teleost, the white sucker.
The present study investigated GnRH forms within the brain of a representative of the order Cypriniformes, the white sucker, Catostomus commersoni, using HPLC, RIA, and immunocytochemistry. Several immunoreactive (ir) GnRH forms were identified in the brain of the white sucker by chromatography and radioimmunoassay, including ir-salmon GnRH, ir-lamprey GnRH-I and -III, and ir-chicken GnRH-II. R...
متن کاملDopaminergic inhibition of gonadotropin-releasing hormone neurons in the cichlid fish Astatotilapia burtoni.
Dopamine regulates reproduction in part by modulating neuronal activity within the hypothalamic-pituitary-gonadal (HPG) axis. Previous studies suggested numerous mechanisms by which dopamine exerts inhibitory control over the HPG axis, ultimately changing the levels of sex steroids that regulate reproductive behaviors. However, it is not known whether these mechanisms are conserved across verte...
متن کاملGonadotropin-releasing hormone (GnRH) modulates auditory processing in the fish brain.
Gonadotropin-releasing hormone 1 (GnRH1) neurons control reproductive activity, but GnRH2 and GnRH3 neurons have widespread projections and function as neuromodulators in the vertebrate brain. While these extra-hypothalamic GnRH forms function as olfactory and visual neuromodulators, their potential effect on processing of auditory information is unknown. To test the hypothesis that GnRH modula...
