Research in the Corey Speers Laboratory includes nomination and validation of expression-based signatures to predict patients that need treatment intensification and signatures to identify patient who will not need further adjuvant therapy for breast cancer. Moreover, this translational work has credentialed a number of novel targets for the treatment of estrogen and progesterone receptor-negative, HER2-negative “triple-negative” breast cancer, a particularly aggressive and difficult to treat form of breast cancer. As PI or co-Investigator on several university-, industry-, private foundation- and NIH-funded grants, the Speers team remains active in the radiation and breast cancer research arena by looking for more effective, targeted therapies for women with breast cancer. These targeted therapies include PARP-inhibitors, BET bromodomain inhibitors, and androgen receptor antagonists as agents for radiosensitization. Our team has also utilized kinome screens to identify novel targets for the treatment of aggressive breast cancers, including triple-negative breast cancer. Finally, we are also interested in the mechanisms of treatment resistance that include modulation of breast tumor initiating cells and understanding novel layers of cancer biology, including the role of long non-coding RNA in triple-negative breast cancer.
Areas of Interest
- Breast cancer- clinical and scientific interest include using genomic and proteomic approaches to identify women who are at high risk for breast cancer recurrence and who may benefit from treatment intensification. Interests also include molecularly based signatures to identify women who are cured after breast conserving surgery and who may not require adjuvant radiation.
- Radiation therapy for breast cancer- Interest includes identifying novel molecular targets for chemo‐ and radio-sensitization in women with triple‐negative or basal‐like breast cancer, including those molecules critical for maintaining breast cancer stem cells.
- Radiation therapy for prostate cancer- Interest includes the identification of molecular targets relevant for the systemic progression and radiation sensitization of prostate cancer.
- Avoiding the over- and under- treatment of patients with breast or prostate cancer
