title: Tripeptide analysis of collagen synthesized by silica-exposed fibroblast cultures.
abstract: The effect of silica on collagen biosynthesis by confluent monolayers of WI-38 fibroblast cultures was examined by a more comprehensive method of analysis. The presence of the particulates had no direct effect on protein (collagen) synthesis, proline incorporation or prolyl hydroxylase activity; the latter is determined by the degree of hydroxylation. Silica, however, was highly toxic to the cells.
