FABP4 and neoplasm: On the other side, PRRX1 is implicated with regulation of mesenchymal cell fate, including myogenesis and skeletogenesis and adipogenesis.45 PRRX1 could influence PPARG, CCAAT/enhancer‐binding protein‐α, FABP4, adiponectin and chemerin.46 However, whether PRRX1 impacts tumour‐induced FFAs remains to be addressed.
