Leptin is an important hormone for the regulation of food intake, energy expenditure and reproduction in mammals, but information regarding its role in teleosts remains scant. In the present study, the gene structures of grass carp (Ctenopharyngodon idellus) and silver carp (Hypophthalmichthys molitrix) leptins were characterized. Recombinant grass carp leptin (rgc-LEP) was expressed in Escheri...

TWEAK and APRIL are important members of the TNF superfamily, which play a crucial role in several diseases. Here, we describe the identification of grass carp (Ctenopharyngodon idella) homologs of TWEAK and APRIL (designated gcTWEAK and gcAPRIL, respectively) and their response to Aeromonas hydrophila and Aquareovirus infection. The gcTWEAK cDNA sequence contains 2273 bases with an open readin...

The study investigated the effects of dietary Eucommia ulmoides extracts on growth, flesh quality and collagen-related genes expression grass carp (Ctenopharyngodon idella). bark extract (EBE) leaf (ELE) were individually supplemented into basal diet (control) at an inclusion 4 g/kg, then three diets fed to (59.7 ± 0.3 g) for 60 days. results indicated that ELE significantly increased weight ga...

Low-molecular-weight nucleotides are very important for fish and terrestrial animals, which have been verified to possess multidirectional biological functions including anti-inflammatory, anti-microbial, anti-oxidant, anti-apoptotic effects. This research was designed fully explore the possible impacts of dietary exogenous supplementation on gill disease resistance, antioxidant capacity, antib...
