Abstract Background: Lung cancer is the most aggressive cancer which representing one-quarter of all cancer-related deaths, and metastatic spread accounts for >70% of these deaths, especially brain metastasis. Metastasis associated mutations are important biomarkers for metastasis prediction and outcome improvement. Methods: In this study, we applied whole-exome sequencing to identify potential metastasis related mutation in 12 paired lung cancer and brain metastasis samples. Results: We identified 1,702 SNVs and 6,131 mutation events in 1,220 genes. Furthermore, we identified several lung cancer metastases associated genes (KMT2C, AHNAK2). A mean of 3.1 driver gene mutation events per tumor with the dN/dS of 2.13 indicating a significant enrichment for cancer driver gene mutations. Mutation spectrum analysis found lung-brain metastasis samples have more similar Ti/Tv(transition/transversion) profile with brain cancer in which C>T transitions are more frequently while lung cancer has more C>A transversion. We also found the most important tumor onset and metastasis pathways such as chronic myeloid leukemia, ErbB signaling pathway and glioma pathway. Finally, we identified a significant survival associated mutation gene ERF in both TCGA (P=0.01) and our dataset (P=0.012). Conclusion: In summary, we conducted a pairwise lung-brain metastasis based exome-wide sequencing and identified some novel metastasis related mutations which provided potential biomarkers for prognosis and targeted therapeutics.

Abstract An integrative multi-omics database is needed urgently, because focusing only on analysis of one-dimensional data falls far short of providing an understanding of cancer. Previously, we presented DriverDB, a cancer driver gene database that applies published bioinformatics algorithms to identify driver genes/mutations. The updated DriverDBv3 database (http://ngs.ym.edu.tw/driverdb) is designed to interpret cancer omics’ sophisticated information with concise data visualization. To offer diverse insights into molecular dysregulation/dysfunction events, we incorporated computational tools to define CNV and methylation drivers. Further, four new features, CNV, Methylation, Survival, and miRNA, allow users to explore the relations from two perspectives in the ‘Cancer’ and ‘Gene’ sections. The ‘Survival’ panel offers not only significant survival genes, but gene pairs synergistic effects determine. A fresh function, ‘Survival Analysis’ in ‘Customized-analysis,’ allows users to investigate the co-occurring events in user-defined gene(s) by mutation status or by expression in a specific patient group. Moreover, we redesigned the web interface and provided interactive figures to interpret cancer omics’ sophisticated information, and also constructed a Summary panel in the ‘Cancer’ and ‘Gene’ sections to visualize the features on multi-omics levels concisely. DriverDBv3 seeks to improve the study of integrative cancer omics data by identifying driver genes and contributes to cancer biology.
