Psychiatry related information on Sea Bream

• Development of enzyme immunoassays for 3,5,3'-triiodo-L-thyronine and L-thyroxine: time-course studies on the effect of food deprivation on plasma thyroid hormones in two marine teleosts, sea bass (Dicentrarchus labrax L.) and sea bream (Sparus aurata L.) [4].
• We examined in a factorial design the effect of dietary protein (45%, 52% and 60%) and lipids (8%, 12%, 17%) on growth performance and circulating growth hormone (GH) levels of fingerling sea bream (5-month-old) fed to satiation with self-feeders [5].

High impact information on Sea Bream

• The significantly wider entrance of the hormone-binding channel in sea bream TTR, in combination with its narrower cavity, provides a structural explanation for the different binding affinities of human and piscine TTR to T(3) and T(4) [6].
• In the gilthead sea bream, we have characterized five different forms of C3 (C3-1, C3-2, C3-3, C3-4, and C3-5); in addition, we have identified and isolated a C5-like molecule [7].
• Here we present evidence for the novel expression of FSHbeta, LHbeta, and the common glycoprotein-alpha (Cgalpha) in the gilthead seabream ovary [8].
• In the pike and seabream, this includes a photodetector, circadian clock, and melatonin synthesis machinery; the trout lacks a functional clock [9].
• Multiple recurrent evolution of trophic types in northeastern Atlantic and Mediterranean seabreams (Sparidae, Percoidei) [10].

Biological context of Sea Bream

• These data and our previous results indicate that LH, but not FSH, stimulates estradiol-17beta production in the ovarian follicle of red seabream through stimulation of aromatase activity and P450arom gene expression and IGF-I enhances the LH-stimulated P450arom gene expression [11].
• The findings support the hypothesis that homologous upregulation of estrogen receptors plays an important role in the estrogen-sensitive control of VTG synthesis in the sea bream liver [12].
• The 1.56 A resolution X-ray structure of sea bream TTR, compared with that of human TTR, reveals a high degree of conservation of the thyroid hormone binding sites [13].
• The aim of this work is the determination of a regulative role of hormones controlling oocyte maturation on vasa mRNA expression in the sea bream ovary through a molecular biology approach [14].
• Signal transduction mechanism of the seabream growth hormone secretagogue receptor [15].

Anatomical context of Sea Bream

• Distribution of TTR was studied in sea bream adult tissue by RT-PCR and was detected in liver, brain, pituitary, gills, kidney, intestine and testis, although northern blot analysis only revealed TTR in the liver, suggesting that in sea bream, liver is the main source of this protein [16].
• We report here the complete nucleotide sequence of a cDNA clone encoding Sparus aurata GHF-1/Pit-1 isolated from an expression library prepared from gilthead seabream pituitary gland poly(A)+ RNA [17].
• Here we studied the metabolism of 18:5n-3 in cell lines derived from turbot (Scophthalmus maximus), gilthead sea bream (Sparus aurata), and Atlantic salmon (Salmo salar) [18].
• Effects of serotonin, GABA and neuropeptide Y on seabream gonadotropin releasing hormone release in vitro from preoptic-anterior hypothalamus and pituitary of red seabream, Pagrus major [19].
• Fenthion was oxidized to fenthion sulfoxide and the oxon derivative, but not to its sulfone, in the presence of NADPH by liver microsomes of sea bream, goldfish, and rats [20].

Associations of Sea Bream with chemical compounds

• Analysis of thyroxine (T4) and triiodo-L-thyronine (T3) binding to sea bream serum proteins demonstrated that both T4 and T3 bind to albumin and TTR [16].
• From these results, the bile salts in the bile of wild red seabream were identified as the conjugates of cholic acid and chenodeoxycholic acid with cysteinolic acid [21].
• Isolation and identification of bile salts conjugated with cysteinolic acid from bile of the red seabream, Pagrosomus major [21].
• The bile from wild red seabream was found to contain two previously unknown bile salts along with two known bile salts, taurocholate and taurochenodeoxycholate [21].
• Differential splicing of three gonadotropin-releasing hormone transcripts in the ovary of seabream (Sparus aurata) [22].

Gene context of Sea Bream

• Adult and juvenile gilthead seabream received implants of estradiol-17beta (E(2)) for 1 wk during the breeding season, and the mRNA expressions of PRL and PRL receptor (sbPRLR) were determined [23].
• Seabream PRLR was detectable in all samples analyzed by this assay [23].
• Isolation and characterization of the 5'-flanking region of the growth hormone secretagogue receptor gene from black seabream Acanthopagrus schlegeli [24].
• In bony fish, although C5 has been identified at the DNA or the protein level in trout, carp and gilthead seabream, only partial C5 sequences are available [25].
• In this study, the distribution of myostatin was investigated during larval and postlarval developmental stages of Sparus aurata(sea bream), Solea solea(sole) and Brachydanio rerio(zebrafish) by immunohistochemistry using antisera raised against a synthetic peptide located within the precursor region of sea bream myostatin [26].

Analytical, diagnostic and therapeutic context of Sea Bream

• Using reverse transcription-polymerase chain reaction and in situ hybridization, the expression of the prolactin (PRL) gene was determined during development in gilthead sea bream (Sparus aurata) for the first time [27].
• A long-term epidemiological study of Cryptosporidium molnari in aquacultured European sea bass (ESB) and gilthead sea bream (GSB) was performed in different types of facilities on the Atlantic, Cantabric, and Mediterranean coasts [28].
• Quantification of prolactin (PRL) and PRL receptor messenger RNA in gilthead seabream (Sparus aurata) after treatment with estradiol-17beta [23].
• The spatial localisation of insulin-like growth-factor-binding protein-2 (IGFBP-2) and its mRNA was investigated during larval and post-larval developmental stages of the gilthead seabream ( Sparus aurata) by immunohistochemistry and in situ hybridisation with specific antisera and riboprobes [29].
• The presence of only one form of PRL in sea bream was supported by identification using Northern blots of only a single transcript of 1.35 kb [30].
