FABP1 and hepatocellular carcinoma: From the data above, it was found that both FABP1 and lipid content in the HCC tissues were lower than adjacent tissues, because FABP1 has a strong affinity for fatty acids, so in order to study the interaction between FABP1 and FFA in HCC cells, the Huh-7 cells were transfected with the FABP1 overexpression lentivirus and then FFAs were added to the cells.
