FABP3 and cancer: The fatty acid–binding protein (FABP) family is involved in fatty acid signalling pathway, which is one of the most importantly involved pathways in cancer development.31 Tang et al showed that the high expression of FABP3 is correlated with poor prognosis in non–small‐cell lung cancer.32 Our results showed that FABP3 promotes the proliferation and migration of ESCC cell lines.
