Prostate cancer is a complex disease, with multiple stages that need to be accurately recapitulated in the preclinical setting. A lack of prostate cancer models which fully represent the benign, latent, aggressive, and metastatic forms of human disease has hampered preclinical research and new drug development.

Patient-derived xenografts (PDX) are known to be more clinically relevant than conventional cell line derived alternatives, providing a new preclinical modelling option. We have developed and validated a panel of prostate cancer PDX models for preclinical studies.

This poster details hormone sensitive and castrate resistant prostate cancer (CRPC) PDX model characterization by H&E staining, immunohistochemistry, and RNAseq, as well as standard of care and new hormonal agent treatment data.

Read this Poster to Discover:

• A well characterized panel of hormone sensitive and CRPC prostate cancer PDX models for predictive preclinical drug development
  
  
• That the PDX models retain the structure of parental tumours, and expression levels of AR and PSA
  
  
• Varied response and resistance to docetaxel, enzalutamide, and abiraterone across the panel of prostate cancer PDX models
