Objective:To investigate the effects of Eriocitrin on the proliferation and migration of Lung adenocarcinoma(LUAD)cells A549 and H1299,and the mechanism of Epithelial-Mesenchymal Transition(EMT).Methods:The effects of different Eriocitrin on the proliferation of LUAD cells A549 and H1299 were examined by CCK8 method.EMT-associated epithelial calmodulin(E-cadherin and N-cadherin),vimentin,ferroptosis-associated protein SLC7A11,GPX4,FTH were detected by Western Blot and expression of mRNA of EMT marker molecules E-cadherin,N-cadherin,Snail were detected by qRT-PCR.Effects of saccharomyces cerevisiae suberin on ferroptosis in LUAD cells as observed by lipid reactive oxygen species(ROS)assay.Results:Eriocitrin could significantly inhibit the proliferative behavior of LUAD cells A549 and H1299 and showed a certain dose-and time-dependence.Compared with the control group,different concentrations of Eriocitrin could significantly reduce the scratch healing rate after 24 and 48 h of action,and the difference was statistically significant(P<0.01).The expression of ROS is increased,EMT-related protein E-cadherin was increased in LUAD cells A549 and H1299 compared with the control group after the intervention with Eriocitrin.N-cadherin and Vimentin expression was decreased.E-cadherin mRNA expression was increased,and N-cadherin,Snail mRNA expression was decreased,expression of ferroptosis-associated protein SLC7A11,GPX4,FTH was decreased,the difference was statistically significant(P<0.05).Conclusion:Eriocitrin may inhibit the proliferation and migration of LUAD cells by regulating the EMT pathway and has potential application in LUAD prevention and adjuvant chemotherapy.
