At the same time, we consistently observed abundance variation of proteins that (to the best of our knowledge) were not previously linked to HCC, such as e.g. Zinc finger protein 207 (ZFP207), which is a kinetochore and microtubule binding protein involved in the mitotic spindle assembly, or fatty acid binding protein 4 (FABP4), which is involved in lipid transport. This evidence concerns the gene FABP4 and hepatocellular carcinoma.
