Candidate radiation sensitizing miRNA verification by MLuc assay and clonogenic survival assay. (A) LNCaP-MLuc (left) or PC3-MLuc (right) cell radiosensitivity following transfection with 20 nM of candidate miRNAs, negative control miRNA (cel-miR-239b) or positive control DNA-PK siRNA (siDNAPK). The% cell viability (mean ± SE, n = 3) following IR (4 Gy) represents the ratio of MLuc activity for irradiated cells to non-irradiated cells for each miRNA on day 11. Control miRNA is noted by the dash line. *, P < 0.05. The miRNAs were organized based on the PC3-MLuc cell radiosensitivity. (B) Clonogenic survival assay of DU145 cells transfected with 20 nM of candidate radiation sensitizing miRNAs or control miRNA. The surviving fraction is reported (mean ± SD, n = 3) following the indicated doses of IR. *, P < 0.05. DMF, Dose Modifying Factor.
