Sequence, genomic organization and expression of two channel catfish, Ictalurus punctatus, ghrelin receptors.
Two ghrelin receptor (GHS-R) genes were isolated from channel catfish tissue and a bacterial artificial chromosome (BAC) library. The two receptors were characterized by determining tissue distribution, ontogeny of receptor mRNA expression, and effects of exogenous homologous ghrelin administration on target tissue mRNA expression. Analysis of sequence similarities indicated two genes putativel...
متن کاملChannel Catfish Ictalurus punctatus
We used a two-compartment, clearance volume-based model to examine rubidium and cesium Ž . pharmacokinetics in channel catfish Ictalurus punctatus after intravascular administration. We compared the apparent volumes of distribution in the central and peripheral compartments and the intercompartmental and whole-body clearances of both metals at 20.0 8C and 27.5 8C. Biological half-times of Rb we...
متن کاملOdorant receptors activated by amino acids in sensory neurons of the channel catfish Ictalurus punctatus
Odorant receptors activated by amino acids were investigated with patch-clamp techniques in olfactory receptor neurons of the channel catfish, Ictalurus punctatus. The L-isomers of alanine, norvaline, arginine, and glutamate, known to act predominantly on different olfactory receptor sites, activated nondesensitizing inward currents with amplitudes of -2.5 to -280 pA in olfactory neurons voltag...
متن کاملMolecular Evolution and Functional Divergence of Trace Amine–Associated Receptors
Trace amine-associated receptors (TAARs) are a member of the G-protein-coupled receptor superfamily and are known to be expressed in olfactory sensory neurons. A limited number of molecular evolutionary studies have been done for TAARs so far. To elucidate how lineage-specific evolution contributed to their functional divergence, we examined 30 metazoan genomes. In total, 493 TAAR gene candidat...
متن کاملIdentification and Characterization of Full-Length cDNAs in Channel Catfish (Ictalurus punctatus) and Blue Catfish (Ictalurus furcatus)
BACKGROUND Genome annotation projects, gene functional studies, and phylogenetic analyses for a given organism all greatly benefit from access to a validated full-length cDNA resource. While increasingly common in model species, full-length cDNA resources in aquaculture species are scarce. METHODOLOGY AND PRINCIPAL FINDINGS Through in silico analysis of catfish (Ictalurus spp.) ESTs, a total ...
