Samy Y. Lamouille, Ph.D.
“Some cancer stem cells are resistant to chemotherapy. If even a small population of these cells are left behind after treatment, then they can rapidly seed the growth of new tumors. By targeting the proteins that are really important for invasion, we may be able to inhibit metastasis in aggressive cancers."
Developing new cancer therapies
If we target cancer stem cells, can we prevent cancer recurrence?
Dr. Lamouille's lab studies how cancer cells communicate and is developing novel therapeutic strategies to target these communication mechanisms to prevent metastases in human cancer progression. In particular, the lab specializes in studying epithelial-mesenchymal transition (EMT) - a process that enables cancer cells to undergo a complete reprogramming at the trasncription, translation, and post-translation levels, leading cancer cells to acquire the invasive characteristics that promote cell proliferation and metastases in new tissues.
The Lamouille Lab analyzes the channel-dependent and -independent roles of connexin proteins during EMT and in cancer stem cells. Transforming Growth Factor-β (TGF-β) is a potent inducer of EMT and regulator of cancer stemness through Smad and non-Smad signaling, and crosstalk with other pathways such as Notch and Wnt. Dr. Lamouille studies how these signaling pathways modulate connexin localization and function in cancer cells that undergo EMT, and in cancer stem cells. The lab is developing novel therapeutic strategies using mimetic peptides to specifically disrupt protein-protein interactions that enhance the tumorigenic characteristics of cancer cells. To carry these discoveries forward and pursue clinical trials, Dr. Lamouille co-founded Acomhal Research Inc. in partnership with Dr. Rob Gourdie.
