Breast Cancer

Research in this laboratory is focused on:

• Identification and therapeutic targeting of underlying mechanisms that contribute to cancer-associated muscle fatigue, with a specific focus on breast cancer. We utilize cell-based models, mouse models of breast cancer, and human tissue biopsies in our experiments. The goal of this research is to develop a supportive therapy that can alleviate the significant muscle fatigue that is common during tumor growth.
• Identification of the communication linking a tumor localized in the breast with systemic muscle fatigue. Experiments to identify tumor secreted factors and their effects on mitochondrial function and associated signaling in muscle tissue are performed using in vitro models and mouse models of breast cancer.
• Analysis of the differential effects of tumor growth on muscle functional properties in female and male mouse models of breast cancer. Development of a male model of breast cancer in an immunocompetent mouse strain.

Current Grants and Contracts

• NIH/NIAMS, NIH/NIGMS, R01AR079445
  • Role: PI
  • 06/2022 - 05/2027
  • The goals of this grant are to understand the mechanisms that contribute to muscle fatigue in patients with breast cancer and to develop a therapeutic strategy to minimize fatigue that commonly occurs in early-stage breast cancer.

Completed Grants and Contracts

• NIH/NIGMS, P20 GM121322, Tumor Microenvironment CoBRE
  • PI Lockman, Project Lead Pistilli
  • 08/2018 - 12/2021 (grant ongoing under PI Lockman until 06/2023)
  • The purpose of this CoBRE application is to develop a Center of Excellence within the West Virginia University Health Sciences Center (WVU HSC) that will focus on studies of the tumor microenvironment (TME), designated the TME CoBRE. The Pistilli project was focused on the role of IL-15 in altering the tumor-infiltrating lymphocytes in the microenvironment as well as the role of IL-15 in stimulating mitochondrial biogenesis in skeletal muscle during breast tumor growth.
