A. Personal Statement
As the Group Leader of Genitourinary Pathology at UT Southwestern Medical Center, the Co-Leader of the Kidney Cancer Program at Simmons Cancer Center, the former Medical Director of Surgical Pathology at Parkland Hospital, and the Co-Director of the Simmons Cancer Center tissue repository I have extensive experience in both prostate and renal cancer. In addition, I serve as the pathologist for our urologic cancer tumor board. My research interests include adult genitourinary cancers and in particular the identification of biomarkers. I’m interested in the development of diagnostic tests with prognostic or predictive value. I have extensive experience in developing immunohistochemistry (IHC) tests, and of greatest relevance to the field of kidney cancer. I have a productive collaboration with Drs. Hsieh and Zheng with several funding and publications.

C. Contribution to Science
- I recently developed IHC assays against two of the 3 most important tumor suppressor proteins, BAP1 and PBRM1. Following on our discovery that BAP1 is inactivated, largely by mutation in 15% of RCC (Pena-Llopis et al., Nat Genet 2012); I developed a highly specific IHC test for BAP1, which I validated in a CLIA laboratory (Kapur et al., J Urol 2014). Using this test, I have been able to determine that BAP1 loss is associated with high Fuhrman grade and mTORC1 activation in ccRCC (Kapur et al., Lancet Onc 2013). Furthermore, I performed BAP1 IHC on the Mayo registry cohort of ~1,400 patients, which led us to find that BAP1 is an independent predictor of survival in patients with localized kidney cancer (Joseph and Kapur, Cancer 2014). I have also developed an IHC test for PBRM1, a second tumor suppressor protein that is lost in ~50% of ccRCC. Using both of these tests, I determined that BAP1 and PBRM1 loss tend to be mutually exclusive (Kapur and Joseph, submitted). Interestingly, I found that the few tumors with simultaneous loss of both proteins have a unique morphology and tend to be rhabdoid (Pena-Llopis et al., Nat Genet 2012). This work established the foundation for the first integrated molecular genetic and pathologic classification of renal cancer.

- We have recently published our data on the first genetically-engineered mouse model of ccRCC (Wang et al., PNAS 2014). An important limitation of the field for many years is the lack of a genetically engineered mouse model (GEMM) of ccRCC reproducing frequent genetic events. Despite the discovery of the VHL gene in 1993, such a model doesn’t exist. We generated mice that were Six2-Cre;VhlF/F;Bap1F/+ and found that these mice developed a spectrum of pre-neoplastic cysts and RCC. These lesions were not found in Six2Cre;VhlF/F and Six2Cre;Bap1F/+ (or younger Six2Cre;Bap1F/F) control mice. Carbonic anhydrase IX (CAIX), a HIF-target and a classic marker of ccRCC, had a membranous staining pattern in cysts and neoplastic nodules. In addition, we observed an increase in phosphorylated S6 ribosomal protein (pS6) staining in the neoplastic nodules. These data unequivocally show that, as we had hypothesized, Vhl and Bap1 cooperate in ccRCC development.

- Using DNA and RNA samples from our tissue bank, we have successfully collaborated with Genetech in publishing the first comprehensive genomic analysis comparing renal oncocytoma and different subtypes of non-clear-cell RCC (nccRCC) including papillary RCC (pRCC), chromophobe RCC (chRCC), translocation RCC and unclassified RCC (Durinck et al. Nat Genet 2015). This study of 167 tumors significantly extends the findings from the TCGA on 66 chRCC. We found many novel mutations that may be implicated in nccRCC pathogenesis and a 5-gene set signature that distinguishes the nccRCC subtypes. The finding that pRCC tumors have more mutations than ccRCC tumors and consequently may have more neoantigens may be important in the development of immunotherapies. Our assessment of morphology and in situ hybridization analyses helped determine that the definition of translocation RCCs needs to be expanded to include novel translocations (involving, for example, MITF) and other genetic changes (such as amplification). Our discovery that eosinophilic chRCC lacks characteristic DNA copy number alterations will facilitate clinical recognition of this unique subtype.

- In addition, I have collaborated with many investigators from various institutions on projects involving optimization, validation, and evaluation of novel IHC markers, tissue microarray construction, and providing expert morphologic opinion on both human and mouse tissue. We are uniquely poised to investigate such clinically relevant questions especially in RCC for the following reasons: 1) a large repository of frozen and paraffin embedded RCC tumors with exome/gene sequencing and Western blot data (this allows us to optimize IHC protocols by providing optimal controls); 2) state-of-the-art tumorgraft models of RCC that can serve to test molecularly targeted therapies; 3) a fully equipped histology and immunohistochemistry laboratory with expertise in development and standardization of IHC assays of new antibodies; 4) the exceptional multidisciplinary camaraderie in the Kidney Cancer Program www.utsouthwestern.edu/kidneycancer.
