The present study provides new insight into valuable information on the diverse structure of anisakid population, discusses limited species richness, and also relationship with other closely diversity-related taxa in NCBI databases Epinephelus diacanthus coioides fish. fishing area consists various locations Arabian Gulf. A total 69 E.coioides E. were examined, (n= 48) infected. Larval stages (...

The enzymes involved in the biosynthesis of long-chain polyunsaturated fatty acids (LC-PUFAs) are widely studied in fish species, as fish are the main source of n-3 LC-PUFAs for human beings. In the present study, a putative gene for elovl5, which encodes a key enzyme involved in LC-PUFA synthesis, was cloned and functionally characterized, and its transcription in response to dietary n-3 LC-PU...

Highlight Research Sex reversal for orange-spotted grouper Epinephelus coioides The application of 17α-methyltestosterone induce sex change stability need more investigation Abstract occurance hermaphrodites in fish causes a scarcity male parents, so an alternative is needed to accelerate sexchange at young age. present study was expected scrutinize the mechanisms sex-change early process, and ...

The insulin-like growth factor type 1 receptor (IGF-IR) belongs to the tyrosine kinase (TK) receptor family. Besides being mitogenic, IGF-IR plays a crucial role in cell survival, transformation and maintenance of the malignant phenotype. In this study, we cloned the cDNA from the hypothalamus of the orange-spotted grouper (Epinephelus coioides) using reverse transcription PCR (RT-PCR) and the ...

Gonadal differentiation is tightly regulated by the initial sex determining gene and the downstream sex-related genes in vertebrates. However, sex change in fish can alter the sexual fate from one sex to the other. Chemical-induced maleness in the protogynous orange-spotted grouper is transient, and a reversible sex change occurs after the chemical treatment is withdrawn. We used these characte...

Lysozyme acts as an innate immunity molecule against pathogen infection. In this study, a new G-type lysozyme gene with a typical G-type lysozyme domain (designated as Ec-lysG) was cloned and characterized from the orange-spotted grouper, Epinephelus coioides. The full-length Ec-lysG cDNA contains 1419 bp and encodes a 256-residue protein containing a 25-residue signal peptide at the N-terminus...
