Figure 12. SFTPC can inhibit PI3K/AKT/mTOR signal transduction. (A–C) A549 cells overexpressing or knocking down SFTPC were subjected to Western blot (A, B) and immunofluorescence (C) assay. (D–F) A549 cells were subjected to Western blot (D, E) and immunofluorescence (F) assays while overexpressing or knocking down SFTPC.
