摘要: Prolonged depolarization has been used as a model of adaptive changes in the expression various proteins, such ion channels and neurotransmitter biosynthetic enzymes, response to increased trans-synaptic activity nervous system. In depolarized PC12 cells, tyrosine hydroxylase (TH) mRNA levels severalfold (Kilbourne, E. J., Sabban, L. (1990) Mol. Brain Res. 8, 121-127). this study, membrane caused an increase reporter gene chloramphenicol acetyltransferase (CAT), under transcriptional control 5' region rat TH gene. These results indicate that leads transcription Protein kinase C inhibitors had no effect on induction by depolarization, well formation CAT upstream The responsive element was mapped containing cAMP element. This also calcium ionophore, ionomycin. Interestingly, combined treatment with analogs greater than either alone levels, cells transfected plasmid
