The increase in LC3-I/LC3-II conversion and/or LC3 aggregation in various cancer cell types exposed to GO nanoparticles [29,30,31,32,33,34,35,36,37,38] and non-excited/photoexcited GQD [39,40,41] indicates an accumulation of autophagosomes (Table 1). This evidence concerns the gene MAP1LC3A and cancer.
