Abstract

Abstract: Objective

To study the inhibitory effect and radiosensitization effects of sodium butyrate （NaBt）， a histone deacetylase inhibitor （HDACi）， on the proliferation of human non-small cell lung cancer A549 cells alone or in combination with X-ray irradiation， and to analyze its combined effect with irradiation on the cell cycle of A549 cells.

Methods

The A549 cells in logarithmic growth phase were divided into control group， different concentrations （5， 10， 15， 20，and 25 mmol·L^－1） of NaBt groups， 4 Gy X-ray irradiation group and different concentrations （5， 10， 15， 20，and 25 mmol·L^－1） NaBt combined with 4 Gy X-ray irradiation groups. CCK-8 method was used to detect the cell proliferation rates in various groups at 24， 48 and 72 h after treatment. The changes of cell cycle were analyzed by flow cytometry.The A549 cells in logarithmic growth phase were divided into control group， 10 mmol·L^－1 NaBt group，20 mmol·L^－1NaBt group， 4 Gy X-ray irradiation group， 10 mmol·L^－1NaBt combined with 4 Gy X-ray irradiation group， and 20 mmol ·L^－1NaBt combined with 4 Gy X-ray irradiation group. At 24 h after treatment， the percentages of A549 cells in each phase of cell cycle in various groups were analyzed.

Results

After 48 h of treatment， the cell proliferation rates in 5，10， 15， 20， and 25 mmol·L^－1 NaBt groups were significantly lower than that in control group（P<0.05 or P<0.01）；after 72 h of treatment， the cell proliferation rates in 5，10，20，and 25 mmol·L^－1 NaBt groups were significantly lower than that in control group（P<0.01） in a concentration- and time-dependent manner；after treated for 48 h， the cell proliferation rates in 15， 20，and 25 mmol·L^－1 NaBt combined with 4 Gy X-ray irradiation groups were significantly lower than those in control group，4 Gy X-ray irradiation group and corresponding concentrations of NaBt groups （P<0.05 or P<0.01）；after treated for 72 h，compared with control group and 4 Gy X-ray irradiation group，the cell proliferation rates in different concentrations of NaBt combined with 4 Gy X-ray irradiation groups were significantly decreased（P<0.01）；the cell proliferation rates in 20 and 25 mmol·L^－1 NaBt combined with 4 Gy X-ray irradiation groups were significantly lower than those in corresponding concentrations of NaBt groups（P<0.01）.The cell cycle analysis results showed that after 24 h of treatment， compared with control group， the percentages of A549 cells in G₀ / G₁ phase and G₂+ M phase in 10 and 20 mmol·L^－1 NaBt groups were significantly increased （P<0.05 or P<0.01）， and the percentage of A459 cells in S phase was significantly decreased （P<0.01）； the percentages of cells in G₂+M phase in 4 Gy X-ray irradiation group and 10 mmol·L^－1NaBt combined with 4 Gy X-ray irradiation group were significantly increased （P<0.05 or P<0.01），and the percentages of cells in G₀/G₁ phase and S phase were significantly decreased （P<0.01）.

Conclusion

NaBt has the inhibitory effect on the proliferation of A549 cells and radiosensitization effect in a concentration- and time-dependent manner， and the combined inhibitory effect of NaBt and X-ray is better than both of them used alone； its mechanism may be related to G₂+ M phase arrest of the A549 cells induced by combination of NaBt and X-ray.
