Scientific Interests

The main focus area in the G.O. (gynecologic oncology) Discovery Laboratory led by Dr. Sanaz Memarzadeh is understanding why some gynecologic cancers, including ovarian and endometrial cancer, relapse despite current standard of care treatments. To understand this clinical challenge, the laboratory team is taking two approaches:

  1. Identification of a population of tumor cells that may be uniquely poised to escape therapy, and
  2. Testing combination treatment options that target unique vulnerabilities in these cells.

Memarzadeh and her team have leveraged remarkable expertise within the UCLA scientific community through collaborative efforts focused on addressing these questions. Ongoing work is aimed at

  1. testing a therapeutic strategy that targets the most common genetic alteration in all human cancers (p53),
  2. assessing whether carboplatin resistant tumor cells resemble other aggressive cancers such as small cell neuroendocrine carcinomas,
  3. testing combinations that may overcome resistance to immune therapy in ovarian cancer, and
  4. defining driver mutations that can initiate cancer in normal gynecologic tissues.

Memarzadeh also has a keen interest in developing and executing clinical trials that can help advance the care of women with gynecologic cancers. As a clinician scientist, Memarzadeh and her team are well-poised to translate scientific findings into potential therapies through innovative clinical trials. They hope to achieve this goal through scientific research in collaboration with other leading-edge expertise at the Jonsonn Comprehensive Cancer Center.
