They used healthy breast cells from the Komen Tissue Bank at the IU Simon Comprehensive Cancer Center to understand the earliest changes in healthy cells as they become cancerous.
“Most of the cancer research to date is focused on understanding what happens when cancer progresses, but the earliest event that leads to cancer initiation has been the hardest to figure out,” Nakshatri said. “The very initial step in cancer is that these cells gain the ability to proliferate, and that’s the very first step that we have been able to make in models using tissue from the Komen tissue bank.”
Nakshatri said the TONSL protein works with other proteins, including one called FACT. In the breast cancer models his team created with the TONSL amplification, the breast cancer was highly susceptible to an existing drug that targets that FACT complex. Now researchers hope these findings can be translated for future breast cancer treatments.

Khatpe, a cancer center trainee in Nakshatri’s lab, received the AACR-Sanofi Scholar-in-Training Award for the research abstract highlighting these findings. She presented the research poster at the American Association for Cancer Research (AACR) 2023 Annual Meeting this week.
Additional authors on the paper include cancer center members Jun Wan, PhD, Yunlong Liu, PhD, Kenneth Nephew, PhD, and Kathy D. Miller, MD. This research was funded in part with support from the Catherine Peachey Fund and the Vera Bradley Foundation for Breast Cancer.
