  • Title: Stimulatory effect of vanadate on hyaluronic acid synthesis in mesothelial cells from rabbit pericardium.
    Author: Ohashi Y, Honda A, Iwai T, Mori Y.
    Journal: Biochem Int; 1988 Feb; 16(2):293-302. PubMed ID: 3130061.
    Abstract:
    Vanadate dose-dependently stimulated the incorporation of [3H]glucosamine into glycosaminoglycan, especially hyaluronic acid, in mesothelial cells from rabbit pericardium. The activity of hyaluronic acid synthase in the mesothelial cells treated with 50 microM vanadate for 0.5-1 h was stimulated to a level about 2 times over that of the control. Neither DNA synthesis nor protein synthesis in the mesothelial cells under the same experimental conditions was affected. The enhancement of the activity of hyaluronic acid synthase in the mesothelial cells treated with vanadate (50 microM) was not inhibited by the addition of cycloheximide (1 microgram/ml). These results suggest that vanadate stimulates the hyaluronic acid synthesis by activation of hyaluronic acid synthase in mesothelial cells from rabbit pericardium.
