Recent data have shown that transforming growth factor-β (TGF-β) plays bi-directional roles in the maintenance of cancer stem cells in a cell-type and context-dependent manner. Zhu and colleagues studied the functions of TGF-β in hemangioblasts from patients with chronic myeloid leukemia (CML), which displayed properties of leukemia-initiating cells (Zhu et al. (2011) J. Biochem. 149, 405-414). They have shown that the BCR/ABL oncoprotein induced the production of TGF-β in the CML hemangioblasts, and that TGF-β activated the PI3K-Akt-NF-κB pathway in these cells. Activation of this pathway enhanced the production of matrix metalloproteinase-9, leading to increased synthesis of soluble Kit ligand and ICAM-1. TGF-β is known to maintain the CML-initiating cells through the Akt-FoxO pathway. Together, these findings suggest that TGF-β may exhibit multiple functions in progression of CML through acting on leukemia-initiating cells.
