ANGPTL4 and hepatocellular carcinoma: The tumor tissues expressed a 2.2-fold lower level of ANGPTL4 mRNA than non-tumor tissues of HCC patients in average, which was statistically significant using unpaired and paired t-tests (2-tailed unpaired t-test, p < 0.0001; 2-tailed paired t-test, p < 0.0001).
