Abstract:
:The effects of a synthetic protein kinase C (PKC) activator, (-)-indolactam V (ILV), were studied in SH-SY5Y human neuroblastoma cells. (-)-ILV induced a translocation of PKC from cytosol to plasma membrane and displaced 3H-phorbol dibutyrate binding in the micromolar range. In addition, (-)-ILV caused a decreased sensitivity of cells to muscarinic agonist-induced Ca2+ mobilization measured with quin-2 and induced a down-regulation of cell surface muscarinic receptors. All the changes induced by (-)-ILV were similar in magnitude to those seen with the phorbol ester tetradecanoyl phorbol acetate (TPA). The results suggest that (-)-ILV is a full activator of PKC and a promising alternative to phorbol esters in studies on mechanism of actions of PKC.
