Using the CBio Portal for cancer genomics (http://www.cbioportal.org) [43, 44], we found that the receptor tyrosine kinase AXL was co-expressed with RUNX2 (Pearson's correlation = 0.56) after analysis of 278 skin cutaneous melanomas (TCGA provisional RNASeqV2 RSEM). Here, RUNX2 is linked to cutaneous melanoma.
