Later works described increased expression of the MUC2 gene in only ~31% of the HCC patients, with mean expression lower (mean −ΔCt = −4.70; 95% CI, −5.88–−3.53) than that in non-HCC tissues (mean −ΔCt = −2.98; 95% CI, −3.99–−1.97). The gene discussed is MUC2; the disease is hepatocellular carcinoma.
