TGFB1 and gastric cancer: While a previous study has demonstrated that ATBF1 translocates to the nucleus with RUNX3 in response to TGFβ stimulation in gastric cancer cells [19], the mechanisms controlling the cellular localization of ATBF1 remain to be illustrated, and whether posttranslational modifications of ATBF1 depend on or determine its nuclear localization is unknown.
