Whereas in gastric cancer cells ATBF1 is located in the cytoplasm and can be tanslocated into the nucleus with RUNX3 upon TGFβ activation [19], we found that ectopically expressed ATBF1 is localized in the nucleus in 22Rv1 prostate cancer cells (Fig. 1) as in normal cells. This evidence concerns the gene RUNX3 and Familial prostate cancer.
