The National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health, has awarded NYU College of Dentistry’s Yi Ye, PhD, a $2.2 million, five-year grant to study the role of Schwann cells, the most prevalent type of cell supporting neurons in the peripheral nervous system, in oral cancer progression and pain.

Oral cancer patients suffer from excruciating pain; their ability to speak, eat, and drink is often severely impaired. Cancer penetrates the nerve, a process termed perineural invasion, causing pain and making the cancer more difficult to treat. How oral cancer invades nerves and causes pain is poorly understood.

“A deeper understanding of the cellular and molecular mechanisms of how oral cancer cells invade nerves will help researchers to identify new targets for treating patients with oral cancer and associated pain,” said Ye, an assistant professor at the Bluestone Center for Clinical Research at NYU College of Dentistry.

Ye studies the neurobiology of oral cancer pain; her research program is dedicated to the understanding of shared molecular and cellular pathways underlying oral cancer progression and pain. In recent years, her lab has been focused on the interaction between oral cancer cells and Schwann cells, which are found in the peripheral nervous system. In response to nerve injury, Schwann cells convert into an activated form to repair neuronal structure and function. One way nerve injury could occur is through cancer cells invading the nerve.

Ye hypothesizes that Schwann cells are activated by oral cancer and can attract cancer cells, creating an environment that supports cancer growth and invasion of the nerve. Activated Schwann cells can also release molecules that are responsible for oral cancer pain. In the newly funded study, Ye and her research team will use a combination of genetic, molecular, electrophysiological, anatomical, and behavioral approaches to understand how Schwann cells are activated by oral cancer cells and identify the pain-causing mediators released by activated Schwann cells.

“Controlling Schwann cell activation or the production of pain-causing mediators could be used as novel strategies for oral cancer pain,” explained Ye. “Our study will explore the potential of shutting down Schwann cell activation to prevent oral cancer from invading the nerve and causing pain.”

The five-year grant (1R01DE029493) began April 1.
