- 요약Over the past twenty years, genome wide association studies (GWAS) have identified over a thousand loci throughout the genome that are associated with cancer risk, but the mechanisms underlying these associations have been more elusive. GWAS point to regions associated with risk but cannot pinpoint the causal variants. Many of these regions do not contain coding variants, suggesting that non-coding variants must mediate cancer risk in some cases.One way these variants may alter cancer risk is by altering enhancer or promoter activity, thereby changing transcription of target genes. Massively parallel reporter assays (MPRA) provide a way to assay thousands of sequences for their ability to alter transcriptional activity. This information, when combined with other data sources like chromatin contacts and eQTL data, can help to implicate suspicious variants and potential target genes.In this work, MPRA of 4,041 SNVs linked to 13 neoplasms comprising a majority of human malignancies was performed in pertinent primary human cell types then integrated with matching chromatin accessibility, looping, and eQTL data to nominate 380 potentially regulatory SNVs and their putative target genes. The latter nominated specific protein networks in lifetime cancer risk, including mitochondrial translation, DNA damage repair, and Rho GTPase activity. A CRISPR knockout screen demonstrated that a large number of these putative risk genes also enable growth of established cancers. Editing one SNV, rs10411210, showed that its risk allele increases RHPN2 expression and stimulusresponsive RhoA activation, indicating that individual SNVs may upregulate cancer-linked pathways. This functional data is a resource for variant prioritization efforts and further interrogation of the mechanisms underlying inherited risk for cancer.
