Cell cycle distribution measured by flow cytometry. Cell cycle distribution histograms of HeLa cells (A) and A549 cells (B) treated with 1P (10 μmol/L) or 1P + ALP for 12 h w/o 6 Gy irradiation. The cell cycle distribution was detected by flow cytometry 24 h after treatment (Data are expressed as mean ± SD, n = 3, and the statistical differences between the groups of G1 phase are shown, ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001).
