Similar to that observed in H2O2-treated U2OS osteosarcoma cells [15], co-immunoprecipitation assays revealed modest TGFβ1 or Dex-regulated interaction between GR and 14-3-3ζ that was further enhanced following combinatorial treatment of cells with both TGFβ1 and Dex. Here, TGFB1 is linked to osteosarcoma.
