Research Interests

Dr. Gorski is interested in three areas of research, two translational, and one clinical. The translational research projects involve developing better systemic treatments for breast cancer, and the clinical project involves his role as the co-director of the Michigan Breast Oncology Initiative (MiBOQI):

1. Repurposing riluzole to treat breast cancer, particularly triple negative breast cancer. Triple negative breast cancer is an aggressive subtype for which there is no targeted treatment and cytotoxic chemotherapy is nearly always required. Thus, there is an urgent need for a "Tamoxifen for triple negative breast cancer", an oral drug with low toxicity. We believe that we have identified a drug (riluzole) that can potentially be repurposed to achieve this goal, as it is an oral drug with very low toxicity and is already FDA-approved for the treatment of the degenerative neurologic disease amyotrophic lateral sclerosis. However, there remain pressing questions about riluzole's mechanism of action that need to be clarified prior to undertaking clinical trials. When we originally identified the anti-TNBC activity of riluzole, it was thought that its antitumor effect derived from its ability to inhibit glutamatergic signaling through metabotropic glutamate receptor-1 (mGluR1) and possibly others.  However, we have recently discovered that riluzole activity does not correlate tightly with mGluR1 expression in breast cancer cell lines. Riluzole also inhibits voltage-gated sodium channels, which have recently been implicated in breast cancer progression. We currently have a Department of Defense Breakthrough Award to do studies clarifying the mechanism of riluzole in inhibiting breast cancer growth as a prelude to clinical trials.

2.  Tumor glucocorticoid receptor status as a predictive marker to improve outcome of chemotherapy in triple negative breast cancer (collaborate tion with Dr. Manohar Ratnam). The synthetic asteroid dexamethasone is often used to premedicate patients receiving chemotherapy for breast cancer because taxanes, a mainstay in breast cancer systemic therapy, can cause severe hypersensitivity reactions. Unfortunately, because dexamethasone stimulates the glucocorticoid receptor (GR), it can antagonize the effects of the very chemotherapy for which it is used to premedicate. Dr. Ratnam and Dr. Gorski are therefore collaborating to use GR as a predictive biomarker for response to treatment, the goal being a clinical trial in order to validate it as a marker.

3. Quality Improvement. Dr. Gorski served as co-director of MiBOQI, a collaborative quality initiative (CQI) involving 25 hospitals in Michigan, from 2013-2016, during which he oversaw or collaborated on several QI initiatives, including postmastectomy radiation therapy, time to chemotherapy after surgery, the use of multigene predictive assays to guide chemotherapy decisions, and the overuse of advanced imaging. Although MiBOQI no longer exists, Dr. Gorski is still interested in local QI initiatives at KCI and the DMC.

Other interests: As the managing editor of Science-Based Medicine (SBM), a weblog devoted to discussing the science of medicine,Dr. Gorski is very interested in science communication and critical thinking, and interested students are welcome to publish in SBM under Dr. Gorski's guidance to hone their writing skills for lay audiences.
