The enhanced production of hyaluronic acid by cultured rat fibroblast cells treated with cyclic AMP and its dibutyryl derivative

The enhanced production of hyaluronic acid by cultured rat fibroblast cells treated with cyclic AMP and its dibutyryl derivative

D Koyama et al. J Cell Physiol. 1975 Dec.

Abstract

Cells of a newly established rat fibroblast line (SEN) in culture synthesize mucopolysaccharides, which have been identified as hyaluronic acid, chondroitin-4-sulfate and heparan sulfate. Treatment of the cells with adenosine 3':5'-cyclic monophosphate resulted in a marked stimulation of production of hyaluronic acid, but not of the other mucopolysaccharides. Treated cells also showed increased activity of hyaluronic acid synthetase, a reduction in growth rate, and morphological alteration. In addition, 5-bromodeoxyuridine was found to counteract greatly the cyclic AMP effect.
