Moreover, 3-MA reduced the autophagy promotion of Fcn B from BLM-induced AMs exosomes on si-cGAS-transfected and BLM-induced lung epithelial cells, exhibiting reduced LC3II/LC3I, Beclin1, and ATG7 expressions, and increased p62 expression (Fig. 6B). This evidence concerns the gene ATG7 and Bloom syndrome.
