RAE1 mediated ZEB1 expression promotes epithelial-mesenchymal transition in breast cancer.

ABSTRACT: Breast cancer metastasis accounts for most of the deaths from breast cancer. Since epithelial-mesenchymal transition (EMT) plays an important role in promoting metastasis of cancer, many mechanisms regarding EMT have been studied. We previously showed that Ribonucleic acid export 1 (RAE1) is dysregulated in breast cancer and its overexpression leads to aggressive breast cancer phenotypes by inducing EMT. Here, we evaluated the functional capacity of RAE1 in breast cancer metastasis by using a three-dimensional (3D) culture system and xenograft models. Furthermore, to investigate the mechanisms of RAE1-driven EMT, in vitro studies were carried out. The induction of EMT with RAE1-overexpression was confirmed under the 3D culture system and in vivo system. Importantly, RAE1 mediates upregulat
