Synopsis

Keywords: Cancer, Metabolism, Models, metastasis, tumor, microenvironmentMetabolic plasticity due to cell intrinsic properties, its inherent dependence on organ of origin as well as its interaction with microenvironmental factors are considered key to establishment of metastases and is believed to be heterogenous. This in turn has a significant impact and differential response to the treatment of choice making this a lethal disease. Here, we investigate using magnetic resonance imaging and spectroscopy the biochemical profile of the same patient derived xenografts of small cell neuroendocrine prostate cancer, an aggressive phenotype, implanted in two different sites, liver and bone that are associated with reduced survival.
