Muscarinic receptor 3 agonist promotes epithelial-meschymal transition in human lung cancer A549 cells by activating PI3K/AKT signaling pathway / 中国病理生理杂志
After treatment with carbachol,the A549 cells showed loss of the close connection and the cell morphology was transformed from irregular polygon to spindle -like cells.The results of Wound healing and Transwell assays showed that the migration and invasion abilites of the A 549 cells were enhanced.Car-bachol increased the vimentin expression and decreased the E-cadherin expression at mRNA and protein level(P<0.05). The phosphorylation of AKT in the A549 cells was up-regulated(P<0.05).These changes was inhibited by M3R antago-nist 4-DAMP.
