Compare tumor vs normal within or across tissue types
Use Xena to compare TCGA tumor samples to GTEx normal samples to see if your gene or transcript is up- or down-regulated in one or more cancer types.
Xena offers two sources of normal tissue: TCGA's solid tisue normal samples from individuals with cancer, and GTEX normal tissue from individuals who do not have cancer.
Example: MYC expression
These two views compare MYC expression between GTEx normal colon tissue to TCGA colon adenocarcinoma. They show that MYC gene expression is highest in tumor samples.
