Title: Potential small-molecule inhibitors of the Tiam1 oncogene product
T-cell lymphoma invasion and metastasis-inducing factor (Tiam)1 is an established proto-oncogene that drives cancer cell migration and metastasis. The correlation between Tiam1 integrity and patient survival, epithelial-mesenchymal transition, and angiogenesis, render it as an important prognostic factor in multiple human malignancies. Tiam1 is a guanine nucleotide exchange factor (GEF) that facilitates the activation of the small GTPase Rac1, thereby controlling cytoskeletal organization, cell polarity, motility, and invasion. In light of the clinical relevance of Tiam1 signaling, we investigated the utility of small molecule inhibitors that target Tiam1 as a therapeutic intervention strategy. We used an in silico computational approach to screen 10 million compounds for candidate drugs that bind to a select patch on Tiam1’s surface. We then identified 13 compounds that inhibit the migration of Tiam1-expressing A549 cells without affecting overall viability. Our studies open the door for a new targeted therapy approach in Tiam1-relevant cancers.
