title: Independent transcriptional regulation of a single VL30 element by epidermal growth factor and activators of protein kinase C.
abstract: A single VL30 element present in the RVL-3 cell line was transcriptionally induced by both epidermal growth factor (EGF) and the protein kinase C (pkC) activators 12-O-tetradecanoylphorbol-13-acetate (TPA) and sn-1,2-dioctanoylglycerol within 5 min of stimulation. Following TPA-induced depletion of protein kinase C activity, EGF stimulation of VL30 transcription and accumulation was unaffected while TPA effects were inhibited, implying that EGF and TPA act by separable pathways.
