Summary of Current Research Interests:
The host microenvironment that supports the growth of tumors encounters a variety of insults during tumor progression. Particularly with the increasing use of genotoxic agents in cancer, there is a significant induction of DNA damage in both tumor cells and the microenvironment. While the DNA damage, cell cycle and apoptosis pathways have been elucidated in the context of tumor cells and their aberrant genomes, it is unclear how genetically normal host cells in the microenvironment perceive and respond to DNA damage. Understanding what factor(s) mediate DNA damage responses in the host cells will a) provide potential targets for sensitizing the tumor microenvironment to genotoxic stress and b) contribute fundamental mechanistic insights into how the different host cell types in the microenvironment handle insults and injuries.
My research interests are focused on understanding how non-coding RNAs shape the tumor microenvironment particularly in the context of various stressors such as genotoxic, inflammatory and oxidative stress. Specific long-term goals of the laboratory include:
1) Understanding the microRNA-target networks in the tumor vasculature and how they handle genotoxic stress such as radiation and chemotherapy.
2) Characterizing the influence of non-coding RNAs on immune co-stimulation in the tumor microenvironment.
3) Engineering host cells with microRNA-coded logic gates to enable tumor infiltration, surveillance and microenvironment reprogramming capabilities. Our laboratory will use a number of approaches ranging from RNA profiling to functional genomics and in vivo screens to identify relevant non-coding RNAs. We will also utilize a number of cellular assays, 3D co-culture systems and mouse models of cancers to understand the biological function of these RNAs. These complementary approaches will provide a framework to address how small perturbations across critical nodes of a network have significant pathological consequences in the tumor microenvironment.
