the intracellular levels of this rna product were increased 2.5- to 5-fold by exposure of the cells to epidermal growth factor ( egf ) and 2- to 3-fold by exposure of the cells to a potent phorbol ester , phorbol 12-myristate 13-acetate , apparently due to regulation at the level of gene transcription .
