As a cellular process that changes epithelial cells to mesenchymal cells,
Epithelial-mesenchymal transition (EMT) plays important roles in development and
cancer metastasis. Recent studies on cancer metastasis have identified many new
susceptibility genes that control this transition. However, there is no
comprehensive resource for EMT by integrating various genetic studies and the
relationship between EMT and the risk of complex diseases such as cancer are
still unclear. To investigate the cellular complexity of EMT, we have constructed
dbEMT (http://dbemt.bioinfo-minzhao.org/), the first literature-based gene
resource for exploring EMT-related human genes. We manually curated 377
experimentally verified genes from literature. Functional analyses highlighted
the prominent role of proteoglycans in tumor metastatic cascades. In addition,
the disease enrichment analysis provides a clue for the potential transformation
in affected tissues or cells in Alzheimer's disease and Type 2 Diabetes.
Moreover, the global mutation pattern of EMT-related genes across multiple
cancers may reveal common cancer metastasis mechanisms. Our further
reconstruction of the EMT-related protein-protein interaction network uncovered a
highly modular structure. These results illustrate the importance of dbEMT to our
understanding of cell development and cancer metastasis, and also highlight the
utility of dbEMT for elucidating the functions of EMT-related genes.
