项目摘要

Recent large-scale cancer genome sequencing studies have uncovered epigenetic regulators as a new major class of cancer genes. SETD2 is one such example. SETD2 encodes a non-redundant H3K36 trimethyltransferase and is frequently mutated in a wide variety of human cancers. Based on TCGA datasets, SETD2 is mutated in 13% of clear cell renal cell carcinoma (ccRCC), 8.9% of uterine corpus endometrial carcinoma, 8.7% of lung adenocarcinoma, 6.9% of bladder urothelial carcinoma, 5.5% of stomach adenocarcinoma, 5.4% of colorectal adenocarcinoma, 5.2% of melanoma, 4.6 % of hepatocellular carcinoma, etc. The majority of SETD2 mutations identified in ccRCC and lung adenocarcinoma are truncating mutations located upstream of the SRI domain that mediates the interaction of SETD2 with RNA polymerase II. Notably, chromosome 3p where SETD2 resides is commonly deleted in both ccRCC and lung adenocarcinoma. Altogether, these cancer genomics data strongly support a tumor suppressor role of SETD2. However, the tumor suppressor function of SETD2 has not been fully established and how SETD2 loss-of-function promotes tumorigenesis remains unclear. Herein, we have generated conditional Setd2 knockout mice to address the tumor suppressor function/mechanisms of SETD2 in kidney cancer. Notably, SETD2 mutations often co-occur with other well-established driver mutations, such as VHL and PBRM1 in ccRCC, MLL-fusions in acute leukemia, and mutations activating the RTK/RAS/RAF pathway in lung adenocarcinomas, suggesting that SETD2 loss probably cooperates with these driver mutations to promote tumorigenesis. Among cancers in which SETD2 mutations have been reported, ccRCC shows the highest mutation rate. Although ccRCC has long been recognized as a VHL loss-driven disease in which VHL is mutated or silenced in up to 80-90% of ccRCC, deletion of Vhl alone is insufficient to induce kidney cancer in mice, indicating that additional genetic event(s) is required to cooperate with VHL loss for kidney tumorigenesis. Here, we hypothesize that VHL loss and SETD2 loss will cooperate to promote ccRCC development, which will be interrogated using genetically engineered mouse models. Furthermore, our genomic studies indicate that SETD2 mutations are associated with ccRCC progression and metastasis. We plan to establish patient-derived preclinical models of metastatic SETD2 mutant ccRCC to investigate the role of SETD2 loss in promoting tumor metastasis. Our goals are to establish physiological preclinical models of ccRCC based on human cancer genomics, to provide mechanistic understanding of how dysregulated epigenetics conferred by SETD2 loss promotes tumor initiation and metastasis, and to discover novel therapeutic vulnerabilities associated with loss of SETD2.
