ABSTRACT
Aim To investigate the effects of gene expression through activating endothelial target for acetylcholine (ETA).Methods Comparative studies were carried out to explore the distinct gene expression of carbachol and pilocarpine.Results Human coronary aortic endothelial cells were incubated with carbachol which activates ETA and muscarinic receptors and with pilocarpine which activates muscarinic receptors distinctly for 10 hours at the concentration of 100 ?mol?L -1.The endothelial gene expression was detected by BiostarH-14112S cDNA expression profiling microarrays containing 14 000 human unigenes. There were 801 differential genes totally (491 differentially expressed both by carbachol and by pilocarpine, 310 differentially expressed by carbachol exclusively). We found a significant increase in expression of 119 and a significant decrease in expression of 191 genes after treatment by carbachol preferentially. And these genes were not affected by pilocarpine. Further globally functional catagorization indicates that there are seven types of distinct expressed genes induced by carbachol selectively including membrane receptors and G proteins, ion channels, G protein coupled receptors, transcriptional factors, apoptosis-related genes, cell adhesive factors, thrombosis and atherosclerosis-related genes.Conclusion The differentially expressed genes evoked by carbachol exclusively are closely associated with ETA and its effectors.
