Comparison of mRNA levels in a GC data set from the NCBI’s Gene Expression Omnibus (GEO) also revealed positive correlations among CGA, EGFR, and GATA2; intriguingly, positive correlations also were observed in a similar analysis of the GEO colorectal cancer (CRC) data set (Supplemental Figure 9, B and C). Here, EGFR is linked to colorectal carcinoma.
