Abstract:
Background and purpose:Metabolism change is one of the main characteristics of the tumor de-velopment. Many studies have conifrmed that cytosolic acetyl-CoA synthetase 2 (ACSS2) plays a critical role in hydro-carbon metabolism of cancer cells. This study aimed to explore the effect of ACSS2 on cellular proliferation, apoptosis and migration of A549 cells by RNA interference.Methods:The ACSS2 interference fragment ACSS2-siRNA and neg-ative control were designed and synthesized for RNA interference followed by the transient transfection in non-small cell lung cancer (NSCLC) cell line A549. Real-time lfuorescence quantitative polymerase chain reaction (RTFQ-PCR) was used to detect ACSS2 mRNA expression. Methyl thiazolyl tetrazolium (MTT), lfow cytometry and wound healing assay were used to detect cell proliferation, apoptosis rate and migration.Results:The expression of ACSS2 mRNA was signiifcantly decreased after transfection with the interference fragment ACSS2-siRNA in NSCLC cell line A549. The proliferation and migration activity of ACSS2-siRNA treated cells were decreased significantly compared with the control group. The apoptosis rate, especially the early apoptosis, was increased..Conclusion:Knockdown of the ACSS2 expression in NSCLC cell line A549 can signiifcantly inhibit the cell proliferation, migration ability and pro-mote the apoptosis rate, especially early apoptosis. This study indicates that ACSS2 may contribute to the progression of human lung adenocarcinoma and may have the potential to serve as a novel therapeutic target.
