Expression level of the ERRFI1 and its role in cell proliferation under irradiation in the SNU-503 and SNU-503R80GY cell lines. a The protein expression of ERRFI1 in three pairs of the induced rectal cancer cell lines was confirmed by Western Blot analysis (P: Parental rectal cancer cell line, R: Radio-resistant rectal cancer cell line) were performed. b The knock-down efficiency of siERRFI1 in SNU-503R80Gy cell line was accessed by RT-PCR. Cell counting c and MTT assay d were performed 96 h after siERRFI1 transfection (N: Negative control)
