Expression of key pathway proteins from the HRR pathway in the radioresistant and radiosensitive NPC tissues. (A) The representative results of NFBD1, BRCA1, BRCA2, RPA1 and RAD51 in radioresistant and radiosensitive NPC tissues. (B) ROC curves for NFBD1, BRCA1, BRCA2, RPA1 and RAD51. (C) Youden Index cutoff values that maximized the sum of sensitivity and specificity were determined for each biomarker (crossed square on curve). The table provides performance values for each biomarker and as a panel. (D) The mRNA expression of NFBD1, BRCA1, BRCA2, RPA1 and RAD51 in radioresistant and radiosensitive NPC tissues.
