BMP9-ID1 signaling promotes EpCAM-positive cancer stem cell properties in hepatocellular carcinoma.

ABSTRACT: The malignant nature of hepatocellular carcinoma (HCC) is closely related to the presence of cancer stem cells (CSCs). Bone morphologic protein 9 (BMP9), a member of the transforming growth factor-beta (TGF-β) superfamily, was recently reported to be involved in liver diseases including cancer. We aimed to elucidate the role of BMP9 signaling in HCC-CSC properties and to assess the therapeutic effect of BMP receptor inhibitors in HCC. We have identified that high BMP9 expression in tumor tissues or serum from patients with HCC leads to poorer outcome. BMP9 promoted CSC properties in epithelial cell adhesion molecule (EpCAM)-positive HCC subtype via enhancing inhibitor of DNA-binding protein 1 (ID1) expression in vitro. Additionally, ID1 knockdown significantly repressed BMP9-promoted HCC-C
