1 Regulation of acetylcholinesterase expression by calcium signaling during calcium ionophore A23187- and thapsigargin-induced apoptosis. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
2 During apoptosis, treatment of HeLa and MDA-MB-435s cells with the calcium ionophore A23187 resulted in a significant increase in acetylcholinesterase mRNA and protein levels. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
3 A23187 also enhanced the stability of acetylcholinesterase mRNA and increased the activity of acetylcholinesterase promoter, effects that were blocked by BAPTA-AM. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
4 A23187 also enhanced the stability of acetylcholinesterase mRNA and increased the activity of acetylcholinesterase promoter, effects that were blocked by BAPTA-AM. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
5 We further demonstrated that the transactivation of the human acetylcholinesterase promoter by A23187 and thapsigargin was partially mediated by a CCAAT motif within the -1270 to -1248 fragment of the human acetylcholinesterase promoter. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
6 We further demonstrated that the transactivation of the human acetylcholinesterase promoter by A23187 and thapsigargin was partially mediated by a CCAAT motif within the -1270 to -1248 fragment of the human acetylcholinesterase promoter. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
7 These results strongly suggest that cytosolic Ca(2+) plays a key role in acetylcholinesterase regulation during apoptosis induced by A23187 and thapsigargin. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
