1 TNF-alpha- or 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ICAM-1 promoter activity was inhibited by a protein kinase C (PKC) inhibitor (staurosporine), tyrosine kinase inhibitors (genistein and herbimycin A), or an Src-specific tyrosine kinase inhibitor (PP2). Tetradecanoylphorbol Acetate SRC proto-oncogene, non-receptor tyrosine kinase Homo sapiens
