The remaining four target genes (ITGA6, NCOA1, Pou4f1 and ST8SIA3) had not been previously reported in HCC and only NCOA1 was included in 49 common genes in the two differential expression genes thus piqued our interest (Figure 3A, 3B and 4A). The gene discussed is NCOA1; the disease is hepatocellular carcinoma.
