A Validated Tumorgraft Model Reveals Activity of Dovitinib Against Renal Cell Carcinoma Sci Transl Med 4, 137ra75 (2012)
Animal models of kidney cancer are lacking. This report shows that human tumors implanted in mice (tumorgrafts) behave like the tumors in patients. Tumorgrafts reproduce the histology, gene expression, and mutations of renal cancer in patients. Furthermore, the treatment responsiveness of renal cancer in patients is preserved in mice. Using tumorgrafts as a model we show that an investigational agent, dovitinib, is superior to two drugs in use in the clinic.

A compelling experimental paradigm coupled with sophisticated bioinformatic and statistical analyses led us to discover that the transcription factor EB (TFEB), a master regulator of lysosomal biogenesis which is translocated in renal tumors, is regulated by mTORC1. The data provide a rationale for evaluating mTORC1 inhibitors in patients with translocation RCC.
