Featured Article in Cell Stem Cell (Nov 09)

Featured article in the November 6, 2009 issue of Cell Stem Cell (access to the Featured Article is free for all readers):
Malignant glioma remains challenging to treat, despite the use of aggressive surgery, radiotherapy, and chemotherapy. Although the concept of cancer stem cells reveals a new framework of cancer therapeutic strategies against malignant glioma, it remains unclear how glioma stem cells could be eradicated. In this issue, Miyazono and colleagues demonstrate that autocrine TGF-β signaling helps maintain glioma-initiating cells and find that chemical inhibition blocks the TGF-β-Sox4-Sox2 signaling axis, resulting in glioma cell differentiation in culture and loss of in vivo tumor-forming capacity. Therefore, clinical disruption of this pathway may represent a therapeutic paradigm against gliomas.
Autocrine TGF-β Signaling Maintains Tumorigenicity of Glioma-Initiating Cells through Sry-Related HMG-Box Factors by Hiroaki Ikushima and 5 co-authors, including Kohei Miyazono, Cell Stem Cell 2009(Nov 6); 5(5): 504-14). [Full text].
