Abstract:
The UCSC Cancer Genomics Browser (https://genome-cancer.ucsc.edu) is a set of web-based tools to display, investigate and analyze cancer genomics data and associated clinical data. Experimental quantities such as gene expression levels, copy number variation and somatic mutations are displayed next to clinical features such as age of onset and cancer subtype. Users can interactively group or sort data by clinical features to dynamically explore how genomic aberrations relate to clinical outcomes. Integrated Kaplan–Meier plots help investigators assess how clinical or genomic values impact long-term survival. The browser currently hosts data from 144 cancer studies including TCGA, CCLE and LINCS. It can display data from multiple studies at once, facilitating cross-cancer comparisons. We are currently interested in hosting new pediatric cancer datasets, and can offer either public or protected access as appropriate. Figure 1 illustrates the power of this approach. It compares patterns of somatic mutations in pediatric high-risk neuroblastoma, a cancer of the peripheral nervous system (Pugh, Morozova et al, Nature Genetics 2013) to those in two adult cancers of the central nervous system: lower grade glioma (LGG, TCGA) and glioblastoma multiforme (GBM, TCGA), and contrasts the age of the patient with frequency of mutations in the Alpha Thalassemia/Mental Retardation Syndrome X-linked (ATRX) gene. The data for all three cancers is sorted by the age of the patient, with yellow being the oldest. The age ranges overlap: the oldest neuroblastoma patients are 16, while the youngest LGG and GBM patients are 14 and 21 respectively. While the three cancers show distinct patterns of somatic mutations, all three show frequent mutations in the ATRX gene in older teens or young adults. This suggests that these cancers may share age-related subtypes with similar genomic signatures. These subtypes may indicate the age-dependent importance of ATRX in the development of both central and peripheral nervous systems, and may ultimately highlight common therapeutic avenues for the two groups of diseases.
