FABP4 and breast cancer: In addition, qPCR analysis showed that the expression of lipid metabolism-related genes (FASN, PPARγ, FABP4, CEBPA, SREBF1) in adipocytes was slightly impacted by EpOME treatment (Supplementary Fig. S3O), which was supported by weak correlations between CYP2J2 and lipid metabolism genes in basal-like breast cancer (Supplementary Fig. S3P–T) using the TIMER2.0 database.
