Dr. Ingle’s team has characterized the functional roles of the estrogen receptor beta (ERβ) variants (ERβ2-5) in breast cancer cells and demonstrated that these variants can interact with ERα and ERβ1 to potentially modify their function, which could impact on the treatment of patients. They have also analyzed ERβ1 in breast cancers from patients and identified that about one-quarter of triple negative breast cancers express ERβ1, a finding that has implications for studying the use of therapies other than chemotherapy for such patients.
Triple negative breast cancer, as many know, is an aggressive form of breast cancer for which no targeted therapies are available. As they have identified that about one-quarter of TNBC are estrogen receptor beta (ERβ) positive, Dr. Ingle’s team will study the effects of drugs directed against ERβ in both cell lines and in laboratory models. These will be the first studies to examine ERβ-targeted therapies in triple negative disease, which have the potential to identify new non-chemotherapy treatments for patients with this type of breast cancer.
Dr. James Ingle is Professor of Oncology and Foust Professor in Mayo Clinic College of Medicine.

He was chair of the Breast Committee of the North Central Cancer Treatment Group for 22 years (1977-1999).
Dr. Ingle’s primary interests are pharmacogenomics and translational research involving endocrine therapy of breast cancer, and the biology of endocrine sensitivity. He has 315 peer-reviewed publications. He has served on numerous national and international bodies such as the NIH (1990, Conference Vice-Chair)) and St. Gallen (2003-2013) Consensus Conference Panels on early breast cancer, serving as Co-Chair of the 2009 St. Gallen Conference. He recently completed his service on the Breast Cancer Steering Committee of the National Cancer Institute (NCI) Coordinating Center for Clinical Trials.
