After comprehensively determining the expression of FABP1 in normal and tumor tissues, Dum D et al. [53] found that FABP1 expression was highly tumor specific, with the highest positive rates in colorectal adenomas (86%), colorectal adenocarcinomas (71.1%) and HCC (65.3%), followed by ovarian mucinous carcinoma (34.6%) and various gastrointestinal adenocarcinomas (10–23%); the positive rate of FABP1 in CCA is only 21.6%. Here, FABP1 is linked to ovarian mucinous adenocarcinoma.
