TMA and IHC results indicated that MAGL levels were increased significantly with decreased degree of tumor differentiation in HCC [MAGL IOD values: I = 67758 ± 27697, II = 171019 ± 49765, III = 443878 ± 132285, IV = 848382 ± 91689 and NLT = 28024 ± 18200 (not showed), Fig. 1E]. This evidence concerns the gene MGLL and hepatocellular carcinoma.
