Therefore, to evaluate the expression of H2A.Z in liver cancer, we recapitulated both H2AFZ and H2AFV expressions in the large cohorts of HCC patients that were available from the National Center for Biotechnology Information (NCBI) and Gene Expression Omnibus (GEO) database (accession numbers GSE14520, GSE16757, GSE22058 and GSE36376), and the data are presented as scatter plots. Here, H2AZ2 is linked to liver cancer.
