Research Interests:

The long-term goal of our research is to understand the molecular mechanisms involved in microenvironmental regulation of cancer progression. Chronic inflammation is a predisposing cause of various cancers. Importantly, inflammation is present in every tumor, including those that are not developed from chronic inflammation.  The inflammatory microenvironment is an essential component that drives tumor progression and has been suggested as the seventh hallmark of cancer. Cancer stem cells (CSCs) are a subpopulation of tumor cells with the ability to undergo self-renewal and recapitulate the entire tumor population. In addition, CSCs have the ability to initiate distant metastasis to form metastatic growth that resemble the primary tumors, and are resistant to conventional chemotherapy/radiotherapy, implicating that they are responsible for tumor growth and recurrence.

Interleukin-1β (IL-1β) is an important mediator of cancer-related inflammation. IL-1β levels are increased in a variety of cancers and elevated IL-1β levels have been associated with tumor prognosis. In collaboration with Dr. Deryl Troyer and Dr. Jishu Shi, we investigate the effects of IL-1β on CSC development and the molecular mechanisms involved in the process. Our research may identify novel therapeutic targets on CSCs for effective cancer treatment.
