N2 - Large-scale human genetic data1,2,3
have shown that cancer mutations display strong tissue-selectivity, but
how this selectivity arises remains unclear. Here, using experimental
models, functional genomics and analyses of patient samples, we
demonstrate that the lineage transcription factor paired box 8 (PAX8) is
required for oncogenic signalling by two common genetic alterations
that cause clear cell renal cell carcinoma (ccRCC) in humans: the
germline variant rs7948643 at 11q13.3 and somatic inactivation of the
von Hippel-Lindau tumour suppressor (VHL)4,5,6. VHL loss, which is observed in about 90% of ccRCCs, can lead to hypoxia-inducible factor 2α (HIF2A) stabilization6,7.
We show that HIF2A is preferentially recruited to PAX8-bound
transcriptional enhancers, including a pro-tumorigenic cyclin D1 (CCND1)
enhancer that is controlled by PAX8 and HIF2A. The ccRCC-protective
allele C at rs7948643 inhibits PAX8 binding at this enhancer and
downstream activation of CCND1 expression. Co-option of a
PAX8-dependent physiological programme that supports the proliferation
of normal renal epithelial cells is also required for MYC expression from the ccRCC metastasis-associated amplicons at 8q21.3-q24.3 (ref. 8).
These results demonstrate that transcriptional lineage factors are
essential for oncogenic signalling and that they mediate tissue-specific
cancer risk associated with somatic and inherited genetic variants.
