Phosphorylation of a gelatin-binding protein from l6 myoblasts by protein kinase c ... This phosphorylation was increased slightly (18%) by phorbol ester treatment of L6 suggesting protein kinase C involvement....
Interference between pathway-specific transcription factors: glucocorticoids antagonize phorbol ester-induced ap-1 activity without altering ap-1 site occupation in vivo.Phorbol esters stimulate and glucocorticoid hormones down-regulate a variety of promoters such as that of the collagenase gene through the transcription factor AP-1 (Fos/Jun)....
Contrasting duration of inhibition of cell-cell communication in primary mouse epidermal cells by phorbol 12,13-dibutyrate and by bryostatin 1The bryosuiiins, macrocyclic lactones isolated on the basis of their antineoplastic activity, activate protein kinase C in vitro and inhibit phorbol ester binding to the enzyme....
Identification of a novel adhesion molecule in human leukocytes by monoclonal antibody lb-2 ...cells largely inhibited adhesion among Epstein Barr virus-immortalized normal B cells (EBV-B) and concanavalin A-stimulated blood mononuclear cells (Con A-BMC) before and after phorbol ester treatment....
