RNA-seq profiling of patient-derived xenograft models in Urothelial Cancer

To probe the tissue source (cancer cell VS stromal cell) of gene expression in the mixed tumor samples, we took advantage of a set of Urothelial Cancer patient-derived xenograft (PDX) models given that the transcriptome in these models is a mixture of human RNA (derived from cancer cells) and mouse RNA (derived from stromal cells). The cohort includes 5 different patient-derived PDX models, 3 replicates for each model, and thus a total of 15 samples
