To find out whether the variability in EGR1 and c-Fos expression is also present in tumor samples of melanoma patients, we analyzed data generated by the TheCancer Genome Atlas (TCGA) Research Network (https://www.cancer.gov/tcga) (32) using the UCSC Xena Functional Genomics Explorer (https://xenabrowser.net). This evidence concerns the gene EGR1 and melanoma.
