1 Carbachol treatment increased the levels of intracellular Ca2+ and inositol 1,4,5-trisphosphate (IP3) and enhanced transcription of the TH gene. Carbachol tyrosine hydroxylase Rattus norvegicus
2 The muscarinic receptor antagonist atropine completely abolished the carbachol effect on TH gene expression. Carbachol tyrosine hydroxylase Rattus norvegicus
3 Transient transfection analysis of the 5" upstream region of TH gene revealed that the AP1 cis-acting element at -205 to -199 bp was responsible for carbachol stimulation. Carbachol tyrosine hydroxylase Rattus norvegicus
4 Thus, Ca(2+)-independent PKC may play a role in carbachol-induced TH gene expression. Carbachol tyrosine hydroxylase Rattus norvegicus
