After transfection, NPC cells overexpressing miR-197-3p showed less autophagy under 4Gy of irradiation and increased autophagy after inhibition, which might be related to the radioresistance of NPC (Figure 6A) and corresponding changed in autophagosomes occurring after GFP-LC3 transfection (Figure 6B, 6C). Here, MAP1LC3A is linked to nasopharyngeal carcinoma.
