Research area

Studying the biological pathways that link psychological stress and breast cancer outcomes, with a focus on the nervous and immune systems.

Impact

Patients who have been diagnosed and treated for breast cancer experience many forms of stress including psychological stress which can activate the immune response and cause inflammation—this negatively impacts breast cancer outcomes. Compelling evidence has emerged that indicates that the immune response and inflammation play a role in tumor initiation, progression, and metastatic spread. Drs. Bower and Cole are focusing on the role of the nervous and immune systems in translating stress from brain to body. These studies aim to define new “positive neurobiology” pathways that can be translated into clinical interventions. Through this work, they hope to establish new paradigms for blocking stress in order to promote both the quality and potentially the length of breast cancer survivorship.

Progress Thus Far

Drs. Bower and Cole are conducting several interrelated lines of research into the association between psychosocial stressors and tumor characteristics in women with early-stage breast cancer. This includes examination of neural processes that link chronic stress and inflammatory processes relevant for tumor progression, as well as intervention studies to reduce stress and identify neuroendocrine pathways that impact tumor biology. In recent work they established a role for the brain’s reward system in blocking stress-induced changes in tumor biology. This led them to develop a laboratory model system to study how to leverage this effect to impact breast cancer growth and metastasis. In addition, they demonstrated that an online version of their mindfulness-based intervention is effective in reducing depression, enhancing well-being, and improving tumor-relevant immune processes in younger women with a history of breast cancer. The team developed several other psychological interventions that can be delivered using an established digital platform. They are testing these interventions that target positive psychological states in women who have completed breast cancer treatment and expanded its to more effectively reach a broad and diverse range of women with breast cancer.

What’s next

Drs. Bower and Cole will continue to test and expand their digital intervention. In addition to this clinical work, they will continue to evaluate their model system to test how activation of the brain’s reward system affects breast cancer growth and metastasis. Both lines of research are designed to establish new parameters for enhancing psychological well-being and blocking the stress effect for breast cancer survivors.

Biography

Julienne E. Bower, PhD is a nationally recognized expert on biobehavioral processes in breast cancer and their impact on health and well-being.  She has conducted pioneering work on neuroimmune interactions in breast cancer survivors, focusing on immune mechanisms for behavioral symptoms such as cancer-related fatigue.  Her research also examines the impact of psychosocial stress on behavioral and biological outcomes in cancer populations, including effects on inflammation and the tumor microenvironment.  Dr. Bower’s current BCRF funded research, conducted in collaboration with BCRF co-grantee Steven Cole is designed to identify the upstream neural processes that regulate inflammatory activity and how these can be modulated by mind-body interventions.  Dr. Bower is an Associate Professor in the UCLA Department of Psychology and the Department of Psychiatry and Biobehavioral Sciences and is also a member of the Jonsson Comprehensive Cancer Center and the Norman Cousins Center for Psychoneuroimmunology.
