Abstract:
A method for discrimination of individuals infected with lymphocystis disease virus(LCDV) or Paralichthys olivaceus individuals having resistance against lymphocystis disease virus is provided to produce of healthy individuals without virus infection, reduce lymphocystis disease occurrence rate by treating lymphocystis disease at an early stage, and selectively produce the excellent Paralichthys olivaceus individuals. A genetic marker for discrimination of fish individuals infected with lymphocystis disease virus has the nucleotide sequence of SEQ ID NO:10, wherein the genetic marker is amplified by a pair of primers having the nucleotide sequences of SEQ ID NO:1 and SEQ ID NO:2, specific to NIF/NLI interacting factor gene; and the fish is Paralichthys olivaceus. The method for discrimination of fish individuals infected with lymphocystis disease virus comprises the steps of: (i) extracting the DNA sample of fish to be discriminated; (ii) amplifying the DNA sample with the primer pair of SEQ ID NO:1 and SEQ ID NO:2; and (iii) analyzing the amplification of the NIF/NLI interacting factor gene that is specific to the infection of lymphocystis disease virus.

Abstract:
The present invention relates to expression vectors and methods for enhancing soluble expression and secretion of a heterologous protein, particularly a bulky folded active heterologous protein which has one or more transmembrane-like domains or intramolecular disulfide bonds by linking a leader peptide with acidic or basic pI and high hydrophilicity thereto; by substituting one or more amino acids within N-terminal of the heterologous protein with ones having acidic or neutral pI and high hydrophilicity; or reducing elevating GRNA value of a polynucleotide encoding the leader peptide having basic pI value and high hydrophilicity. The expression vector and the method may be used to produce of heterologous protein and to transduce of therapeutic proteins in a patient by preventing formation of insoluble inclusion body and by enhancing secretional efficiency of the heterologous protein into the periplasm or outside cell.
Abstract:
PURPOSE: A novel gene encoding Paralichthys olivaceus-derived antibacterial peptide, bea-defensin is provided to ensure pivotal immune response function and to be used in developing natural antibiotics. CONSTITUTION: A Paralichthys olivaceus-derived antibacterial polypeptide comprises: a polypeptide encoded by cDNA having one of nucleic acid sequence among sequence numbers 1-5; a polypeptide encoded by gDNA having one of nucleic acid among sequence numbers 6-10; or a polypeptide having one of amino acid sequence among sequence numbers 11-15. The antibacterial polypeptide is anionic. Antibiotics or feed additives contain the antibacterial polypeptide, mutant thereof, or active fragment thereof as an active ingredient.
