A recent study analyzed the protein expression of FABP1 among 150 different tumor types containing 17,071 samples using a tissue microarray and found that the highest FABP1 positivity rates were observed in colorectal adenomas (86%), in colorectal adenocarcinomas (71.1%), and in hepatocellular carcinomas (65.3%), followed by mucinous carcinoma of the ovary (34.6%), cholangiocarcinoma (21.6%), and various adenocarcinomas from the digestive tract (10–23%) (48). This evidence concerns the gene FABP1 and neoplasm.
