Abstract: Objective The aim of this study was to investigate the effects of NFATc1 expression on the proliferation,apoptosis,migration and invasion of lung adenocarcinoma NCI-H1299 cells,and its specific biological mechanisms. Methods Real time PCR was used to detect the relative levels of NFATc1 in three lung adenocarcinoma cell lines,and the NCI-H1299 cell line with stable knockdown of NFATc1 was constructed using lentivirus vectors.A MTT assay was used to detect the effect of NFATc1 on cell proliferation,the cell colony assay was used to detect the effect of NFATc1 on clone formation,the Transwell assay was used to detect the effect of NFATc1 on cell migration and invasion,and flow cytometry was used to detect the effect of NFATc1 on cell cycle and apoptosis.Western blot was used to detect the effects of NFATc1 on apoptosis,EMT-related proteins and MAPK signaling pathways protein expression. Results The expression of NFATc1 in lung adenocarcinoma NCI-H1299 cells was relatively high.Silencing NFATc1 expression could significantly inhibit cell proliferation(P<0.05),clone formation(P<0.05),migration(P<0.05)and invasion(P<0.05),the cell cycle arrested at the G1 phase(P<0.05),and promote apoptosis(P<0.05).The expression of Bax,cleaved caspase-3 and E-Cadherin protein increased(P<0.05),and CDK4,c-Myc,ERK,p-ERK and N-Cadherin protein expression decreased(P<0.05). Conclusion Inhibition of NFATc1 expression in human lung adenocarcinoma NCI-H1299 cells can significantly inhibit cell proliferation,arresting cell cycle,migration and invasion,and promote cell apoptosis.The mechanism may be related to the inhibition of MAPK signaling pathway.
