Sestrin2 is necessary for mTORC1 repression during AAD. (A) Immunoblots of lysates from wild-type and Sesn2−/− MEFs cultured in leucine-free medium for up to 24 h. (B) Immunoblots of lysates from wild-type and Sesn2−/− MEFs cultured in amino acid-free media as indicated for 24 h. (C) Immunofluorescence against mTOR and the lysosomal marker LAMP2 in wild-type, Gcn2−/−, and Sesn2−/− MEFs cultured in ±leucine medium for 24 h. Bars, 10 µm.
