a Effects of BPIFB1 on clone formation ability of CNE2 cells after irradiation with a dose of 0–8 Gy. b Numbers of surviving foci are presented as bar graphs representing means ± SD. c Effects of BPIFB1 on survival rate of CNE2 cells after radiotherapy. Surviving fractions were calculated as described based on the data from experiments depicted in b. d CCK8 assays were used to investigate the role of BPIFB1 in CNE2 cell proliferation before and after irradiation. *P < 0.05; **P < 0.01; ***P < 0.001
