To determine whether MAFF recognizes specific sequences in the CXCL1 and CSF3 genes, we searched for specific DNA binding peaks in UCSC genome browser database.42 Data from the ENCODE consortium,42 SYDH track (GEO: GSM935306), showed MAFF specific binding to CXCL1 and CSF3 loci in HEPG2 hepatocellular carcinoma cells. The gene discussed is CSF3; the disease is hepatocellular carcinoma.
