For example, in the case of both MKI67 and HJURP, microarray analysis revealed significant increases in expression in the GE2-HCC subgroup only, whereas qPCR analysis detected upregulation in both of the HCC subgroups, although a much higher relative level was detected in the GE2-HCC subgroup as well. The gene discussed is MKI67; the disease is hepatocellular carcinoma.
