Peachey Grant empowers PICR scientists to push breast cancer research forward


The Catherine Peachey Breast Cancer Research Grant continues to advance the work of Purdue Institute for Cancer Research scientists and others who are pursuing solutions to breast cancer’s most difficult challenges, from metastasis and therapy resistance to early detection.

Supported by the Catherine Peachey Fund in partnership with the Women’s Global Health Institute, the program promotes projects that are well positioned to move from basic discovery toward clinical application. The initiative honors Cathy Peachey, one of the founders of the Indiana Breast Cancer Coalition, whose legacy continues to inspire progress in breast cancer research and treatment.

Advancing RNA-based therapeutics for aggressive breast cancer

Andrea Kasinski, a recipient of the 2025 Peachey Grant, is developing an RNA-based therapeutic for triple-negative breast cancer, an aggressive subtype with limited treatment options. Her research focuses on improving a tumor-suppressing molecule known as miR-34a so it remains stable and active in the body for longer periods of time. By pairing the optimized therapy with a specialized delivery strategy designed to improve circulation and tumor targeting, the project aims to advance a promising new treatment approach toward future clinical testing.

Kasinski is the deputy director of the Purdue Institute for Cancer Research and Walther Professor of Cancer Biology in Purdue’s College of Science.

Targeting chromatin remodeling to limit metastasis

A 2025 grant was awarded to Emily Dykhuizen for her project targeting the PBAF chromatin remodeling complex in metastatic breast cancer. Her team is investigating how disrupting this complex can reduce tumor growth and improve immune response. The work could help identify a new therapeutic strategy to combat metastasis, a leading cause of mortality among breast cancer patients.

Dykhuizen is a professor of medicinal chemistry and molecular pharmacology in Purdue’s College of Pharmacy.

Developing blood-based biomarkers for early detection

W. Andy Tao, recipient of the 2024 Peachey Grant, is developing blood-based biomarkers to detect BRCA-related breast cancer before tumor growth occurs. His research focuses on identifying functional proteins in plasma-derived extracellular vesicles that could serve as highly sensitive indicators of early-stage disease, offering a new avenue for noninvasive screening.

Tao is a professor of biochemistry in Purdue’s College of Science.

Enhancing radiotherapy through immune-targeted nanoparticles

Matthew Scarpelli, also recognized in 2024, is studying macrophage-targeted therapies to make radiotherapy more effective for breast cancer patients. His work repurposes an FDA-approved iron nanoparticle, ferumoxytol, to target tumor-supporting macrophages, with the goal of improving radiation outcomes and anti-tumor immune responses.

Scarpelli is an assistant professor of medical physics in Purdue’s College of Health and Human Sciences.

Uncovering lipid metabolism’s role in breast cancer metastasis

Dorothy Teegarden, recipient of the 2023 Peachey Grant, is investigating how cellular lipid storage contributes to metastasis. Her research examines proteins associated with cytoplasmic lipid droplets and their roles in cell adhesion and ferroptosis, two pathways that may influence how breast cancer cells spread to new sites.

Teegarden is a professor of nutrition science, director of the Women’s Global Health Institute, and associate director of the PICR Cancer Research Training and Education program.

Revealing genome integrity defects that drive breast cancer

Ann Kirchmaier, also a 2023 recipient of the Peachey Grant, is investigating how errors in DNA replication and repair contribute to breast cancer development and progression. Her project aims to identify genome-wide sites of replication fork stress and determine how those defects influence drug sensitivity in tumor cells. Working with co-investigator Nadia Atallah Lanman, the team’s research explores how targeting these vulnerabilities could inform precision medicine strategies and lead to more effective chemotherapeutic approaches.

Kirchmaier is an associate professor of biochemistry.

Engineering 3D microtumor models for drug discovery

Luis Solorio, awarded the Peachey Grant in 2021, is developing a high-throughput, magnetically actuated 3D microtumor model to study how the physical properties of the tumor environment influence metastatic breast cancer growth and drug responsiveness. His research aims to improve understanding of how mechanical forces in the metastatic microenvironment affect whether tumor cells remain dormant or continue to grow, with the goal of enabling more precise drug evaluation.

Solorio is an associate professor of biomedical engineering.

Together, these projects reflect the strength and breadth of Purdue’s breast cancer research. By supporting early-stage, high-impact studies, the Peachey Grant program empowers PICR investigators to pursue new scientific directions that could one day lead to more precise, effective, and life-saving breast cancer treatments.
