Brachyury has been characterized as a driver of epithelial-mesenchymal transition process which is regarded as an important mechanism of cancer cell invasion and metastatic progression.
The present study aimed to assess the influence of Brachyury on the expression of 23 MMP members and to further explore the mechanisms involved in the promotion of NSCLC cell invasion by Brachyury and MMPs in the H460 and H1299 stable cell lines.
The migratory and invasive capacities of Brachyury-SMMC7721 and Brachyury-HepG2 transfected cells were evaluated using in vitro scratch wound healing and Matrigel invasion assays, respectively.
Conversely, inhibition of Brachyury resulted in downregulation of mesenchymal markers and loss of cell migration and invasion and diminished the ability of human tumor cells to form lung metastases in a xenograft model.
