A renal cell carcinoma tumorgraft platform to advance precision medicine
Ontology highlight
ABSTRACT: Renal cell carcinoma (RCC) encompasses a heterogenous group of diseases, creating challenges for drug development. Preclinical models which are both translatable and representative of disease heterogeneity are needed. Patient-derived xenograft (PDX) or tumorgraft (TG) models recapitulate the biology and treatment responsiveness of RCC. Through the orthotopic implantation into NOD/SCID mice of tumor samples from >900 ethnically-diverse patients at UT Southwestern Medical Center and the affiliated county hospital, we have generated a resource comprising 172 independently-derived stably-engrafted TG lines from 148 patients. The lines have been characterized histologically and genomically (whole exome sequencing [n = 97] and RNA sequencing [n =102]). They represent a variety of histological and on
cogenotypes including representative TCGA clades further validated through orthogonal metabolomic analyses in a subset. We illustrate how this platform has enabled a deeper understanding of the biology and molecular genetics of RCC, the development of both tissue- and imaging-based biomarkers, as well as advances in drug development. This resource expands the diversity of models available to the scientific community to advance precision diagnosis and therapy in RCC.
