Neoplastic association of enhanced type V collagen production in rat fibrosarcoma.
Collagens present in the connective tissues of the extracellular matrix of fibrosarcoma were isolated and characterized. The fibrosarcoma was induced in rats by the administration of 3-methylcholanthrene. The results obtained were compared with normal muscle. An excess amount of type V collagen was found to be produced by the fibrosarcoma tissue compared to the normal muscle. Type V collagen from fibrosarcoma was characterized on the basis of solubility behavior in sodium chloride solutions, electrophoretic mobility on SDS-polyacrylamide gels, elution pattern of phosphocellulose chromatography and amino acid composition.
