Effects of Prolactins on the Chromatophores of the Tilapia, Oreochromis niloticus
General and Comparative Endocrinology, 1993Using isolated scales and split-fin preparations of the tilapia Oreochromis niloticus, the effects of a pair of prolactins of the tilapia Oreochromis mossambicus (tPRL177 and tPRL188) and of ovine prolactin (oPRL) on chromatophores were studied in vitro. These peptides caused melanosome aggregation and dispersion of xanthosomes, especially in the split

Gene transfer in tilapia (Oreochromis niloticus)
Aquaculture, 1988Abstract The microinjection of the human growth hormone gene into the germinal disc and the development of 90-day live transgenic tilapia are reported. Three different spawns, treated 10 min, 21–24 h or 40–43 h after spawning, were used. For microinjection a linear 4.0 kb EcoRI-DNA fragment containing the mouse metallothionein-I promoter (mMT-I ...

Mercury exposure in the freshwater tilapia Oreochromis niloticus
Environmental Pollution, 2010Mercury (Hg) can be strongly accumulated and biomagnified along aquatic food chain, but the exposure pathway remains little studied. In this study, we quantified the uptake and elimination of both inorganic mercury [as Hg(II)] and methylmercury (as MeHg) in an important farmed freshwater fish, the tilapia Oreochromis niloticus, using (203)Hg ...

Focusing on the functional characterization of the anserinase from Oreochromis niloticus
International Journal of Biological Macromolecules, 2019Carnosine, anserine and homocarnosine are the three most representative compounds of the histidine dipeptides family, widely distributed in mammals in different amounts depending on the species and the tissue considered. Histidine dipeptides are mainly degraded by two different carnosinase homologues: a highly specific metal-ion dependent carnosinase ...

Nile Tilapia Oreochromis niloticus (L.)
2017Nile tilapia Oreochromis niloticus (L.) is one of the most widely cultured and most widespread invasive fish species globally. It was the most common alien fish species in South China where it has successfully established populations in the major rivers, and became the dominant species in many sites.

Evaluation of etoxazole toxicity in the liver of Oreochromis niloticus
Pesticide Biochemistry and Physiology, 2004Abstract The effects of etoxazole were evaluated in freshwater fish Oreochromis niloticus from five different sublethal etoxazole concentrations in order to study the biochemical response, photometrically. No changes were observed in the activities of antioxidant enzymes such as superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.11.1.6 ...

Complete mitochondrial genome of the hybrid of Oreochromis niloticus (♀) × Oreochromis aureus (♂)
Mitochondrial DNA Part A, 2014In this paper, the complete mitochondrial genome of the hybrid of Oreochromis niloticus (♀) × Oreochromis aureus (♂) was determined using PCR-based method. The mitogenome was 16,663 bp in length, containing the same gene order and an identical number of genes or regions with the other Cichlid fishes, including 13 protein-coding genes, 2 rRNA genes, 22 ...
