Research Abstract

Molecular defects of collagen or proteoglycans including the replacement of amino acid in poly-peptide chains, were found in hereditary connective tissue diseases. Northern and southern blot analyses using cDNA of collagen <alpha>1(I)- and <alpha>2(I)-chain, showed depression of <alpha>2(I) gene expression from a variant form of Ehlers -Danlos syndrome. The study of collagen structure, in health and disease, frequently requires fractionation and peptide analysis of the collagen chains. In order to micro-analysis of the heterogenity of newly synthesized collagen from hereditary connective tissue diseases, revers-phase HPLC system was more useful for the rapid separation and the recovery of polypeptide chains than the ordinary CM cellulose chromatography. Two dimensinal electrophoresis uwing iso-electrophocasing as first dimension and DDS- polyacrylamide gel electrophoeresis as second from CNBr peptides of <alpha>-chains which were separated by reverse-phase HPLC, could be detected the molecular heterogenity of collagen. Dermatan sulfate proteoglycans which associate collagen fibril, were found several forms in interstitial connective tissues. The defect of dermatan sulfate proteoglycans were occured in a case of Ehlers- Danlos syndrome. In order to more clarify the cause of the proteoglycan deficiency, we attempt to cDNA cloning from guinea pig skin fibroblast culture.
