Abstract:
PURPOSE: An insect glycosaminoglycan and a method for preparing the same are provided to ensure anti-inflammation, anti-diabetes and anticancer and to prevent and/or treat diseases caused by functional disorder of vasodilation. CONSTITUTION: A composition for anti-inflammation contains insect glycosaminoglycan. The insect glycosaminoglycan is cicada Paecilomyces japonica glycosaminoglycan, glycosaminoglycan having repetitive ΔUA-2S-[1-4]GlcN structure or Velarifictorus asperses glycosaminoglycan. The composition is a pharmaceutical composition or cosmetic composition. A composition for anti-diabetes or anticancer contains the insect glycosaminoglycan as an active ingredient.
Abstract:
PURPOSE: A coprisin peptide with antifungal activity, isolated from Copris tripartitus is provided to apply to antibiotics, food preservative, cosmetic product preservative, and medicine preservative without cytotoxicity. CONSTITUTION: A peptide isolated from Copris tripartitus has an antifungal activity and is denoted by sequence number 1. A coprisin is the peptide isolated from Copris tripartitus. The peptide comprises 43 amino acids. An antifungal pharmaceutical composition contains the peptide of sequence number 1 as an active ingredient.
Abstract:
A transformed insect cell containing human beta-1,4-galactosyltransferase and rat alpha-2,6-sialyltransferase and having an enhanced sugar chain addition function and a production method of glycoproteins from the same transformed insect cells are provided to improve production stability and economic efficiency of useful sugar proteins derived from human by using inexpensive insect cells. The transformed insect cell containing human beta-1,4-galactosyltransferase and rat alpha-2,6-sialyltransferase and having the enhanced sugar chain addition function is produced by transforming an insect cell line Sf9 with a recombinant vector containing the human beta-1,4-galactosyltransferase gene and rat alpha-2,6-sialyltransferase gene. The glycoproteins which are added sialic acid or sialic acid and galactose are produced by culturing the transformed insect cell.
Abstract:
PURPOSE: An expression vector for transforming an insect cell line is provided which has high expression efficiency and is thus used in mass-producing a foreign gene product. And an insect cell line transformant is also provided, which introduces the vector and produces antibacterial protein, Nuecin. CONSTITUTION: The expression vector pAcIE1-Neo-hsp consists of Baculovirus AcNPV IE1 promoter-neomycin resistant gene-Drosophila heat shock protein promoter-foreign gene inserting site(restriction enzyme EcoRV)-SV40 poly(A)-IE1 structural gene. The expression vector pAcIE1-Neo-hsp is constructed by: inserting neomycin resistant gene under the control of IE1 gene promoter of insect Baculovirus AcNPV; introducing a strong Drosophila heat shock protein promoter; placing a foreign gene inserting site, EcoRV site under the control of the promoter; and inserting animal virus, SV40 poly(A) site for the termination of transcription. The expression vector pAcIE1-Neo-hsp-Nuecin is constructed by inserting Nuecin cDNA gene into foreign gene inserting site, EcoRV site of pAcIE1-Neo-hsp.
