title: Biochemical and ultrastructural alterations accompany the anti-proliferative effect of butyrate on melanoma cells.
abstract: The effect of sodium butyrate on mouse and human melanoma cell lines was evaluated. Sodium butyrate (0.1-2mM) is shown to reduce the clonogenic potential of several melanoma cell lines. The antiproliferative effect of sodium butyrate is accompanied by a marked increase in the activity of the plasma-membrane bound enzyme gamma-glutamyl transpeptidase. Sodium butyrate treated cells acquire a well developed rough endoplasmic reticulum and accumulate fat droplets. The development of the endoplasmic reticulum is associated with a marked increase in the activity of the enzyme marker NADPH cytochrome c reductase. It is suggested that the phenotypic alterations induced by sodium butyrate may serve as markers for the action of this agent on melanoma cells and other tumours.
