Abstract

The recurring association of specific genetic lesions with particular types of cancer is a fascinating, and largely unexplained area of cancer biology. This is particularly true of clear cell renal cell carcinoma (ccRCC) where although key mutations such as loss of VHL is an almost ubiquitous finding, there remains a conspicuous lack of targetable genetic drivers. In this study, we have identified a previously unknown pro-tumorigenic role for the RUNX genes in this disease setting. Analysis of patient tumor biopsies together with loss of function studies in preclinical models established the importance of RUNX1 and RUNX2 in ccRCC. Patients with high RUNX1 (and RUNX2) expression exhibited significantly poorer clinical survival compared to patients with low expression. This was functionally relevant as deletion of RUNX1 in ccRCC cell lines reduced tumor cell growth and viability in vitro and in vivo. Transcriptional profiling of RUNX1-CRISPR-deleted cells revealed a gene signature dominated by extracellular matrix remodelling, notably affecting STMN3, SERPINH1, and EPHRIN signaling. Finally, RUNX1 deletion in a genetic mouse model of kidney cancer improved overall survival and reduced tumor cell proliferation. In summary, these data attest to the validity of targeting a RUNX1-transcriptional program in ccRCC. [Abstract copyright: Copyright ©2020, American Association for Cancer Research.]
