we used cloned cdnas homologous to 21 different protooncogenes to screen for their expression at the mrna level in human peripheral blood mononuclear cells ( pbmc ) stimulated with the mitogenic lectin phytohemagglutinin ( pha ) , and we compared the time course of accumulation of mrnas for these protooncogenes to that of mrnas for the il2 , il2r , tfr , and histone h3 genes .
