FABP4 and non-small cell lung carcinoma: Tang et al. [61] studied the expression of FABP3 and FABP4 in NSCLC patients and found a significant increase of their mRNA expression in cancerous tissues compared to non-cancerous; high levels of FABP3 or FABP4 expression were associated with advanced tumor node metastasis stage and negatively affected the overall survival of NSCLC patients.
