Dietary Therapy of Prostate Cancer
We use the RapidCaP mouse model of lethal prostate cancer to test novel therapy approaches. Most recently, we show that and how a pro-oxidant dietary supplement can suppress disease progression. This is after anti-oxidants like vitamin E were shown to increase prostate cancer risk in men.
We combine three major approaches to explore new therapies:
- we explore how the vitamin K pre-cursor menadione can suppress prostate cancer
- we use genome wide screens and cell imaging techniques to understand how oxidative stress can selectively kill cancer cells
- we study how dietary choices could become target therapy in various disease settings

The Neuro-Metastasis Interface
A major challenge in metastasis research is the identification of factors that control progression of non life-threatening tumors to lethal metastatic disease. In spite of much knowledge on the role of tumor neuron interactions in primary prostate cancer, the role of neurons in metastatic prostate cancer remains to be defined. We recently developed whole organ imaging of metastatic tumors in their native environment. Now we map and manipulate interactions between the peripheral nervous system and metastatic lesions in collaboration with neuroscientists at CSHL.

Understanding Metastasis – Designing models of lethal cancer
We have developed the RapidCaP model system for metastatic prostate cancer. It uses surgery for gene manipulation in the prostate. This approach allows us to visualize and probe metastasis biology in the fully native and immune competent setting. We use it to define the stepwise progression from primary tumor escape to colonization of metastatic sites such as bone, liver and brain. This research is boosted by the use of single cell genome analysis and our recent adaptation of microscopy for whole organ imaging at single cell resolution.
