The Genetic Landscape of Cancer

Cancer is a genetic disease. Some cancers are inherited and other cancers arise from genetic mutations or viral infections that occur during your life. But every cancer is driven by a dysfunctional genetic operating system.

Tumor Gene Expression Data (Transcriptome)

The analyses from are based on the genetic profile of each cancer type. In order define these profiles, we are aggregating genetic data from the repository at NCBI GEO (National Center for Biotech Info – Gene Expression Omnibus). Specifically, we are aggregating expression data generated using the Affymetrix GPL570 microarray. This section contains the master files with all of the cancer types together. If you want to compare the genetic profiles of 2 different cancer types, this is the section for you.

Genetic Profile Explorer

The link below will open a program that allows you to explore and compare the gene expression profiles of the cancer types we have analyzed. This program includes the average gene expression profile for every cancer subset we have analyzed. For more info on how to use and interpret the data from this program, read our Guide to Using the Gene Expression Spider Plot. Note: This link works best when opened with Google Chrome.
