钙敏感受体通过PI3K/AKT通路对缺氧诱导的A549细胞增殖的影响
Calcium-sensing receptor mediates hypoxia-induced proliferation of A549 cells through PI3K/AKT pathway
摘要
Abstract
AIM:To explore the cell signal transduction pathway of calcium-sensing receptor ( CaSR) media-ting hypoxia-induced proliferation of A549 cells and A549/DDP cells.METHODS: The cell proliferation was tested by BrdU incorporation assay .The cell cycle analysis was carried out by flow cytometry .The protein levels of PCNA and p-AKT were analyzed by Western blot .RESULTS: Hypoxia significantly increased the protein levels of PCNA and p-AKT, the BrdU incorporation and the cell proliferation index .GdCl3 ( an agonist of CaSR ) amplified the effect of hypoxia .LY294002 (a PI3K inhibitor) decreased the up-regulation of PCNA expression, the BrdU incorporation and the increased cell prolifer-ation index induced by hypoxia and GdCl 3 in the A549 cells and A549/DDP cells.CONCLUSION:CaSR is expressed in A549 cells and 549/DDP cells, and CaSR activation induced by hypoxia promotes the proliferation of A 549 cells and A549/DDP cells through PI3K/AKT signaling pathway .关键词
