Figure Lengend Snippet: Figure 4. Non-canonical Rag GTPase Regulation in Steady-State ESCs (A and B) Tfe3 localization (A) and retention of self-renewal after 3 days of 2i withdrawal (B) of the indicated genotypes. Average and SD of 2 biological replicates are shown. Scale bar, 20 mm. (C) mTORC1 activity in ESCs in response to amino acids. Arrows mark fast-migrating (unphosphorylated) and slow-migrating (phosphorylated) 4EBP1. (D) Retention of self-renewal after 3 days of 2i withdrawal in the indicated cell lines in the absence or presence of 20 nM rapamycin. Average and SD of 2 biological replicates are shown. (E and G) Tfe3 subcellular localization in the indicated ESCs with or without 20 nM rapamycin (E) and Tsc2 KO.1 ESCs expressing the indicated Rag constructs (G). Scale bar, 20 mm. (F) Retention of self-renewal relative to empty vector-transfected cells in Tsc2KO.1 cells expressing the indicated transgenes after 3 days of 2i withdrawal. Average and SD of 2 biological replicates are shown.
