Core Tip

Core Tip: Our study investigates FAM53B in regulating macrophage M2 polarization and its potential mechanisms in promoting pancreatic ductal adenocarcinoma (PDAC) metastasis. Our research revealed a significant upregulation of FAM53B in PDAC tissues, which was associated with the malignant features of the tumors. Experimental findings indicated that FAM53B can enhance macrophage M2 polarization, leading to increased release of anti-inflammatory factors. Murine model results further confirmed the role of FAM53B in PDAC metastasis, as inhibiting FAM53B suppressed tumor invasion and metastasis. Therefore, FAM53B promotes PDAC metastasis by regulating macrophage M2 polarization.
