High impact information on Cichlids

• Extensive MHC variability in cichlid fishes of Lake Malawi [5].
• Species-specific differences in jaw shape are obvious early in cichlid larval development and are correlated with patterns of bmp4 expression in the mandibular primordium [6].
• Three GnRH receptor types in laser-captured single cells of the cichlid pituitary display cellular and functional heterogeneity [7].
• The reconstruction of cichlid RH1 pigments with 11-cis-retinal from 28 sequences showed that the absorption spectra of the pigments of nine species were shifted toward blue, tuned by two particular amino acid replacements [8].

Chemical compound and disease context of Cichlids

Anatomical context of Cichlids

• We describe a cDNA clone derived from the bony (cichlid) fish Paralabidochromis chilotes and show that it encodes a protein related to the CD94/NK cell group 2 (NKG2) subfamily of the killer cell C-type lectin receptors [15].
• The goitrogen 6-n-propyl-2-thiouracil (PTU) given during testis development increases Sertoli and germ cell numbers per cyst in fish: the tilapia (Oreochromis niloticus) model [16].
• Neuropeptide Y in the forebrain of the adult male cichlid fish Oreochromis mossambicus: distribution, effects of castration and testosterone replacement [17].
• We have studied ORD of thyroxine (T4) and 3,3',5'-triiodothyronine (rT3) in liver and kidney microsomes of fish, i.e. tilapia (Oreochromis niloticus) [18].

Associations of Cichlids with chemical compounds

• Cortisol rapidly reduces prolactin release and cAMP and 45Ca2+ accumulation in the cichlid fish pituitary in vitro [20].
• Thyroid hormone and estrogen regulate brain region-specific messenger ribonucleic acids encoding three gonadotropin-releasing hormone genes in sexually immature male fish, Oreochromis niloticus [21].
• Single-cell real-time quantitative polymerase chain reaction of immunofluorescently identified neurons of gonadotropin-releasing hormone subtypes in cichlid fish [22].
• The authors examined the effects of both light and circadian phase on the synthetic activity of the dopamine producing enzyme, tyrosine hydroxylase (TH), in the retina of the Midas cichlid (Cichlasoma citrinellum) [23].
• Intracranial injections of 10 micrograms melatonin, with or without 4 micrograms naloxone, result in reduced aggressive responsiveness by the cichlid fish Aequidens pulcher to a mirror presented 20 min later [24].

Gene context of Cichlids

• Cloning and characterization of type III iodothyronine deiodinase from the fish Oreochromis niloticus [25].
• We suggest that this new variant in cichlids, like that in mammals, encodes an MITF transcriptional factor having higher relative DNA binding affinity [26].
• Identification of chemokines and a chemokine receptor in cichlid fish, shark, and lamprey [27].
• Using degenerate primers based on conserved zebrafish and fugu TIP39 nucleotide sequences, 3'-RACE reactions isolated the coding region of a putative TIP38 cDNA in the Nile tilapia (Oreochromis niloticus) [28].
