Figure Lengend Snippet: Growth factors activate TBK1 in a TBKBP1-dependent manner. a,b , Immunoblot analysis of S172-phosphorylated (p-) and total TBK1 in the lysates of HEK293T cells transfected with TBK1 along with Kras G12D ( a ) or RalB ( b ). c,d , Immunoblot analysis of TBK1 S172 phosphorylation in EGF-induced A549 cells stably transduced with vector control or Kras G12D ( c ) and RalB ( d ). e , Immunoblot analysis of S172-phosphorylated (p-) and total TBK1 in whole-cell lysates of A549 cells stimulated by EGF, Insulin or FBS. f,g, Immunoblot analysis of S172-phosphorylated (p-) and total TBK1 in whole-cell lysates of EGF-stimulated lung cells from WT or Tank KO mice ( f ) or EGF-stimulated A549 cells stably transduced with a control shRNA (shCtrl) or shRNAs for Tank ( g , upper panel) and Nap1 ( g , lower panel). h,i , Immunoblot analysis of S172-phosphorylated TBK1 (p-TBK1) and the indicated other proteins in whole-cell lysates of control or Tbkbp1 -knockdown A549 cells stimulated with the indicated growth factors ( h ) or PRR ligands ( i ). Data are representative of three independent experiments. Unprocessed blots are shown in .
