1 The CCAAT-binding factor CBF/NF-Y regulates the human acetylcholinesterase promoter activity during calcium ionophore A23187-induced cell apoptosis. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
2 We previously reported that the expression of acetylcholinesterase during A23187-induced apoptosis of HeLa cells is regulated by Ca(2+) mobilization through the modulation of mRNA stability and acetylcholinesterase promoter activity. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
3 We previously reported that the expression of acetylcholinesterase during A23187-induced apoptosis of HeLa cells is regulated by Ca(2+) mobilization through the modulation of mRNA stability and acetylcholinesterase promoter activity. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
4 Transactivation of the human acetylcholinesterase promoter by A23187 was partially mediated by the distal CCAAT motif within the -1270 to -1248 fragment of the human acetylcholinesterase promoter, which was bound by the CCAAT binding factor (CBF/NF-Y). Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
5 Transactivation of the human acetylcholinesterase promoter by A23187 was partially mediated by the distal CCAAT motif within the -1270 to -1248 fragment of the human acetylcholinesterase promoter, which was bound by the CCAAT binding factor (CBF/NF-Y). Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
6 In the present study, we investigated the molecular mechanisms by which CBF/NF-Y regulates A23187-induced activation of the human acetylcholinesterase promoter. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
7 Our results suggest that acetylcholinesterase promoter activation during A23187-induced HeLa cell apoptosis may result partly from the dissociation of CBF/NF-Y from the distal CCAAT motif in the acetylcholinesterase promoter, reversing this suppression. Calcimycin acetylcholinesterase (Cartwright blood group) Homo sapiens
