CXCR4 inhibits cell apoptosis and promotes G2/M arrest. (A) AGS-EBV cells grown in the presence or absence of siCXCR4 were incubated with either rapamycin or DMSO for the last 6 h of the total incubation time. Apoptosis was measured by Annexin V/PI staining. Representative data are shown as the mean ± SD. (B) PI staining was used to determine the distribution of G2/M cells in the siCXCR4, siCXCR4+rapamycin, rapamycin, DMSO and control groups. Representative data are shown as the mean ± SD.
