To determine whether FKBP5 contributes to the autophagy-regulated radioresistance of NPC cells, we transfected siFKBP5 and Ad-mRFP-GFP-LC3 into radioresistant CNE2R cells and found that the number of autophagic LC3 spots in the siFKBP5 group sharply decreased in comparison with the negative control of siRNA (Figure 6D). Here, FKBP5 is linked to nasopharyngeal carcinoma.
