The effect of phorbol esters on ganglioside metabolism in contact-inhibited Chinese hamster V79 cells was examined. Three phorbol esters of varying structure and tumor-promoting activity were used. Treatment of cells with tumor-promoting phorbol esters resulted in accumulation of gangliosides and increased incorporation of [1-14C]palmitate and [9-3H]sialic acid into gangliosides. Moreover, the phorbol esters were found to increase the activity of CMP-sialic acid: lactosylceramide sialyltransferase, the enzyme catalysing the first step in ganglioside biosynthesis. The magnitude of phorbol ester effects on V79 cell ganglioside metabolism correlated with the in vivo phorbol ester tumor-promoting activity.
