FABP4 interacts with PPARγ to promote malignant progression in pancreatic cancer

Chenxi Yang, Cun-Xia Li, Qian Zhang, Jing Yun et autres

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy with an exceptionally poor prognosis. Fatty acid-binding protein 4 (FABP4) has been implicated in tumorigenesis and peroxisome proliferator-activated receptor γ (PPARγ) signaling, but its precise functional role and underlying molecular mechanisms in PDAC …
