RP loss increases phospo-S6 kinase signaling. (A) Western blot analysis showing the expression of phosphorylated S6 kinase in GFP-LC3 HEK cells transfected with siScr or siRPS19 and either untreated or treated with 100 nM rapamycin overnight. (B) Western blot analysis of phosphorylated S6 kinase expression in CD34+ cord blood cells infected with a control shRNA (shScr) or an shRNA against RPS19 (shRPS19). (C) Western blot analysis of phosphorylated S6 kinase expression in LCLs derived from a normal control or DBA patients. (D) Western blot analysis of phosphorylated S6 kinase expression in 2 dpf zebrafish embryos.
