Specialty / Expertise

Treatment of prostate, bladder and testicular cancer

Research Interests

  • Optimizing hormonal therapy for prostate cancer.
  • Determining mechanisms by which prostate cancer cells become resistant to therapy.
  • Clinical trials.

Current Research Projects

Title: Defining and Exploiting Molecular Mechanisms of Androgen-Metabolism for Prostate Cancer Therapy
Funding: Damon Runyon Cancer Research Foundation
The goals of this proposal is to delineate the cellular mechanisms by which prostate tumors maintain or ‘buffer’ intratumoral androgens levels in the castrate microenvironment and to evaluate the pre-clinical efficacy of novel agents targeting these pathways.

Title: Maximal Inhibition of the Androgen Axis for Prostate Cancer Therapy
Funding: National Institutes of Health/National Cancer Institute
The goal of this project is to test the hypothesis that complete inhibition of testicular, adrenal, and intraprostatic androgen production will be necessary to achieve maximal suppression of intraprostatic androgen levels and maximal tumor cell apoptosis and growth inhibition.

Title: Assessment of Prostatic Androgen Activity Following Testosterone Suppression
Funding: Prostate Cancer Foundation
The goal of this project is to assess the intraprostatic androgen environment following testosterone suppression by assaying tissue androgen levels, steroidogenic enzymes, and androgen regulated gene expression.

Title: Exploring the Role of Steroid Transport Genes in Prostate Cancer Progression and Response to Therapy
Funding: Pacific Northwest SPORE, NIH/NCI                                                      
The goal of this project is to characterize the expression and functional role of steroid transport proteins in the response to hormonal therapy in men with localized and advanced prostate cancer.

Title: Optimizing Treatment of Advanced Prostate Cancer and Exploiting Mechanisms Driving Castration Resistance
Funding: Department of Defense Prostate Cancer Research Program
The goal of this project is to delineate resistance mechanisms underlying recurrent prostate tumor growth after progressively stringent AR pathway blockade, and to evaluate the differential sensitivity of tumors recurring after progressive AR inhibition to the repressive effects of testosterone therapy, using the LuCaP35 tumor xenograft model.

 

Training

Dr. Mostaghel received her AB from Harvard University, Cambridge MA and her MD and PhD from Duke University in Durham, NC. She completed her Internal Medicine Residency at the University of California, San Francisco, and was a Post-Doctoral Fellow in Oncology at the University of Washington and Fred Hutchinson Cancer Research Center, Seattle, WA.
