To elucidate the role of nitric oxide synthase (NOS), which produces the free radical nitric oxide (NO), and nicotinamide adenine dinucleotide phosphate oxidase (NOX), which produces the superoxide anion (O), in the innate immunity of Eriocheir sinensis, the full lengths of the NOS and NOX genes were cloned via rapid amplification of the cDNA ends and then expressed in the prokaryotic form to obtain the recombinant proteins, NOS-HIS and NOX-HIS. Through bacterial binding and stimulation experiments, the molecular mechanisms of NOS and NOX in the innate immunity of E. sinensis were explored.

The members of sMaf have a high homology basic leucine zipper (bZIP) and lack trans activation domain, and could interact with other transcriptional regulatory factors as a molecular chaperone. In this study, a full-length MafG-like gene was cloned from Procambarus Clarkii, designated as PcMafG-like, which consisted of an ORF length of 246 bp encoding 82 amino acids, a 5' untranslated region (UTR) of 483 bp, and a 3' UTR of 111 bp.

In mammals, cell division cycle-25a (Cdc25a) is a member of the Cdc25 family of cell division cycle proteins. It is a phosphatase that plays an important role in cell cycle regulation by dephosphorylating its substrate proteins.

However, the underlying cause of this disease remains unclear. To better understand the pathogenesis and pathogenic mechanism of HPND, we compared the transcriptome differences of the hepatopancreas of E.

Deltamethrin contamination has resulted in a threat to the healthy breeding of the Chinese mitten crab, Eriocheir sinensis. In this study, we investigated transcriptional responses in the hepatopancreas of E.

We compared the nucleotide variations in the mtDNA genomes among three geographical groups of Culter alburnus: Liangzi Lake, Hubei Province (referred to as LZH); Taihu Lake, Jiangsu Province (TH); and Poyang Lake, Jiangxi Province (PYH).

The complete mitochondrial genome was 16,634 bp, and the gene order was identical to that of teleost fishes. Compared with the previous reported weather loach in China, there were numerous nucleotide substitutions and length polymorphisms on the structural genes of mitochondrial DNA in the loach from the Poyang Lake.
