چکیده مقاله:

Kruppel-like factors (Klfs) are a highly related zinc-finger family of transcription factors implicated inthe regulation of the eukaryotic cellular growth and differentiation of a diverse set of cells in mammal. UsingRT-PCR technique, a 456 bp cDNA fragment encoding N-terminus part of a Klf2b was isolated from the skinmucosa of common carp (Cyprinus carpio) using two degenerative oligonucleotide primers. Use of thisfragment as a probe allowed the isolation of a larger cDNA clone through the searching of the GenBankexpressed sequence tag database. The size of the amplified product is 1157 bp, which encodes a polypeptide of 274 amino acid residues with a predicted molecular mass of 30.359 kDa and theoretical pI of 4.88. The deduced amino acid sequence exhibited 79, 54, and 53% identity to the homologous Klf2b identified from zebrafish Danio rerio, Spotted Green Pufferfish Tetraodon nigroviridis and Atlantic salmon Salmo salar, respectively. The common carp protein is 50% similar to Klf2 orthologues in African clawed frog Xenopus laevis, 44% in chicken Gallus gallus and is 30% similar to the mammalian Klf in house mouse Musmusculus.

Common Carp, Cyprinus carpio

The common carp (Cyprinus carpio) belongs to the family Cyprinidae. In nature, carp live in the middle or lower reaches of a river with slow currents, or in marshes. Their habitats are usually weedy areas with a muddy bottom. Carp fry feed on zooplankton such as rotifers and copepods, but as they grow up they become benthic feeders, feeding on animals and other organic material. The cyprinids h...

Molecular characterization of apolipoprotein A-I from the skin mucosa of Cyprinus carpio

Apolipoprotein A-I is the most abundant protein in Cyprinus carpio plasma that plays an important role in lipid transport and protection of the skin by means of its antimicrobial activity. A 527 bp cDNA fragment encoding C terminus part of apoA-I from the skin mucosa of common carp was isolated using RT-PCR. After GenBank database searching, a partial sequence containing a coding sequence (CDS)...

Effects of water-borne cadmium on the skin of the common carp (Cyprinus carpio).

The skin of carp, Cyprinus carpio, was studied at the ultrastructural level after exposure of the fish to low and high concentrations of cadmium in the water (22 and 560 micrograms/L, respectively) for different periods. The effects of the low concentration of cadmium were similar to those of the high concentration, although they appeared later. The basal lamina and the skin surface became high...
