After extracting cell protein and tumor tissue protein, Western blotting results showed that FANCG expression decreased in the niraparib tosylate group and the radiotherapy group, and the FANCG expression was the lowest in the combined treatment group, with statistically significant differences (P < 0.01) (Fig. 4-1 and Supplementary Fig. 5). This evidence concerns the gene FANCG and neoplasm.
