Abstract: OBJECTIVE: To study mechanisms in sensitivity of paclitaxel-resistant human lung adenocarcinoma cells from treatment with resveratrol. METHODS: A549/Taxol-R,a human lung adenocarcinoma cell line that resist paclitaxel,was established and treated with different concentrations of resveratrol and paclitaxel alone or in combination. MTT assay was performed and SPSS was used to calculate IC50 of A549/Taxol-R to paclitaxel. Change of IC50 was determined after treatment with resveratrol at different concentrations. Apoptosis rates were detected with flow cytometry. Expressions of Bax,Bcl-2 and Caspase-3 were detected by Western blot. RESULTS: The inhibitory rate of resveratrol to A549/Taxol-R cells was dependent on concentration and time. After treated with resveratrol,the IC50 of paclitaxel on A549/Taxol-R cells decreased from (17.50±1.24) μg/mL to (4.18±0.62) μg/mL. The apoptosis and necrosis rates of A549/Taxol-R cells that were treated with combined resveratrol and paclitaxel were higher than those that treated with single drugs (P < 0.05). Expression of Bax and Caspase3 in the combined treatment group was higher than that in the single treatment group,while expression of Bcl-2 was relatively down-regulated (P < 0.05). CONCLUSION: Resveratrol may increase sensitivity of paclitaxel-resistant human lung adenocarcinoma cells to paclitaxel by promoting cell apoptosis. The mechanism may be related to promotion of expression of Bax and Caspase3 and down-regulation of Bcl-2 expression.
