Hypoxia promotes lung adenocarcinoma A549 cells migration by upregulating acetyl-CoA carboxylase 1 / 解剖学报

ABSTRACT

Objective To investigate the mechanism of hypoxia to promote human lung adenocarcinoma A549 cells migration through acetyl-CoA carboxylase 1 (ACCI). Methods Lung adenocarcinoma A549 cells were treated with hypoxia (5% 02 ). Transwell migration assay was used to detect cell migration ability. Western blotting was used to detect ACCI expression and epithelial-mesenchymal transition (EMT) related protein expression. Results Compared with the normoxia (control group), hypoxia treatment promoted the migration of A549 cells (P<0.01), ACCI expression was up- regulated after hypoxia treatment (P<0.01), and vimentin expression was detected to increase significantly (P<0.05), E- cadherin expression decreased (P<0.01) ; Compared with the control group, migration of A549 cells was inhibited (P<0.05), vimentin expression was down-regulated (P<0.05), and E-cadherin expression increased after knocking down ACC1(P<0.01). After ACCI was knocked down, the differences between the numbers of migration of A549 cells under normoxia and 5% 0
