Abstract：【Objective】 To investigate the effect and mechanism of ciprofloxacin (CIP) on apoptosis of lung cancer cells induced by (tumor necrosis factor-associated apoptosis inducing ligand,TRAIL).【Methods】 Human adenocarcinoma A549 cells were divided into blank control group (untreated), CIP group (CIP 100μg/mL in medium), trail group (trail 50 ng/mL in medium) and combination group (CIP 100 μg/mL and trail 50 ng/mL in medium);Trypan blue staining was used to calculate cell viability;The expression of death receptor 4 (DR4), death receptor 5 (DR5) and CCAAT / enhancer binding protein homologous protein (CHOP) were detected by Western blot.【Results】 There was no significant difference between the blank control group and the CIP group in A549 cell viability (P>0.05). The cell viability of the TRAIL group and the CIP group was lower than that of blank the control group and the CIP group (P<0.05), and the A549 cell viability of the combined group was significantly lower than that of the trail group (P<0.05). At 24 h and 48 h, the relative expression levels of CHOP, DR4 and DR5 in the TRAIL group were significantly higher than those in the blank control group and the CIP group (P<0.05), and the relative expression levels of CHOP, DR4 and DR5 in the combined group were significantly higher than those in the TRAIL group (P<0.05). 【Conclusion】 TRAIL combined with CIP can up regulate the expression of DR4 and DR5 in A549 cells, reduce the viability of A549 cells, and increase the apoptosis level of A549 cells; CHOP may play an important role in CIP induced DR5 up regulation and lung adenocarcinoma A549 cell apoptosis, which is worthy of further clinical research
