Research/Clinical Interest
Mechanisms that regulate tumor progression, metastasis and drug resistance; crosstalk between the tumor cells and their microenvironment
Our research goals are to define mechanisms that regulate tumor progression and metastasis, to apply this knowledge to complement and extend current clinical applications and provide additional therapeutic strategies. The microenvironment surrounding the cancer cells is an active participant in regulating tumor cell behavior. We are investigating the dynamics of the interactions between tumor cells and their microenvironment, researching how tumor cells manipulate their milieu and, conversely, how the reactive tumor microenvironment influences tumor cell plasticity, invasion, metastasis, and response to therapy. Our work identified the tumor suppressor, Merlin, as an important modulator of breast cancer. Further, we have discovered that Merlin is modulated by factors extrinsic to the tumor itself. Work is underway to investigate the impact of the mutually sustaining synergy between tumor and stromal cells and how that impacts the molecular homeostasis and promotes evolution of the malignant phenotype with a focus on determining the mechanisms and implications of post-translation modifications of Merlin protein. Another exciting aspect involves investigations of Hedgehog signaling. We have determined that Hedgehog signaling in tumor cells upregulates the expression of microenvironment modulators that influence tumor vascularization and metastasis. Ongoing investigations are centered on understanding the mechanisms and implications of autocrine and paracrine Hedgehog signaling in influencing tumor progression, metastasis and resistance to therapy.
