Technology description follows.
Title of invention: Novel metastatic serous epithelial ovarian cancer (SEOC) genetically engineered mouse models, cell lines, and orthotopic models based on Rb, p53 and/or Brca 1/2 inactivation useful for biomarker discovery and preclinical testing.
Description of Technology: The high mortality rate from ovarian cancers can be attributed to late-stage diagnosis and lack of effective treatment. Despite enormous effort to develop better targeted therapies, platinum-based chemotherapy still remains the standard of care for ovarian cancer patients, and resistance occurs at a high rate. One of the rate limiting factors for translation of new drug discoveries into clinical treatments has been the lack of suitable preclinical cancer models with high predictive value.
NCI CAPR has developed Tri-allelic K18-T121 tg/+ /Brca1 fl/fl /p53 fl/fl SEOC GEM Model, GEM-derived SEOC orthotopic mouse model, and biological materials derived therefrom, with several key histopathologic, immunophenotypical, and genetic features of human SEOC. SEOC GEMs were utilized to create orthotopic immunocompetent transplant models, and to generate synchronized cohorts of mice suitable for preclinical studies. NCI CAPR conducted studies that determine these models are tractable for use in routine efficacy studies and demonstrate the utility of these models in evaluating the potential efficacy of novel therapeutics for ovarian cancer.
Potential Commercial Applications:
- These models serve as a foundation for preclinical research and evaluation of efficacy of novel therapeutics for ovarian cancer.
- The GEM models described here can be used to develop cell lines and allograft models for evaluating drug potency relative to Brca1 mutation status.
- These mouse models provide the opportunity for evaluation of effective therapeutics, including prediction of differential responses in Brca1-wild type and Brca1-deficient tumors and development of relevant biomarkers.
- Novel resource for evaluating disease etiology and biomarkers, therapeutic evaluation, and improved imaging strategies in epithelial ovarian cancer
- Similarity to human ovarian cancer based on transcriptional profiling
- Suitable preclinical cancer models with high predictive value.
Development Stage: Pre-clinical (in vivo validation).
