The fraction of tumour cells expressing CD133 (Prominin-1), a marker for both neural stem cells and brain cancer stem cells, is enriched after radiation in gliomas. Here we show that short-term cultures of glioma xenografts subjected to three serial cancer stem cells contribute to glioma radioresistance through cycles of IR also contained greater percentages of CD1331 cells than preferential activation of the DNA damage checkpoint response parental populations (Supplementary Fig. S2). Glioma stem cells promote radioresistance by preferential activation of the DNA damage response. Ionizing radiation represents the most effective therapy for glioblastoma (World Health Organization grade IV glioma), one of the most lethal human malignancies, but radiotherapy remains only palliative because of radioresistance. Glioma stem cells promote radioresistance by preferential activation of the DNA damage response Bao S, Wu Q, McLendon RE, Hao Y, Shi Q, Hjelmeland AB, Dewhirst MW, Bigner DD, Rich JNGlioma stem cells promote radioresistance by preferential activation of the DNA damage response. cancer stem cells contribute to glioma radioresistance through preferential activation of the DNA damage checkpoint response and an increase in DNA repair capacity. The fraction of tumour In response to radiation, cells activate the DNA damage response (DDR), which initiates a series of cascades involving cell cycle checkpoint activation, various forms of DNA repair and, if unsuccessful, inducing apoptosis.

2006 Dec 7;444(7120):756-60. Epub 2006 Oct 18. PMID 17051156 : Anaplastic oligodendroglioma. Blakeley J, Grossman S. Glioblastoma remains the most common and devastating primary brain tumor despite maximal therapy with surgery, chemotherapy, and radiation. The glioma stem cell (GSC) subpopulation has been identified in glioblastoma and likely plays a key role in resistance of these tumors to conventional therapies as well as recurrent disease. Glioma stem cells promote radioresistance by preferential activation of the DNA damage response. Nature 2006; 444 : 756–760.

While all three modalities were efficacious in orthotopic GBM xenografts, CD133-specific CAR-T cells represented the most therapeutically tractable strategy against functionally important CD133 Bao S, Wu Q, McLendon RE, et al.

CAS Article Google Scholar Glioma stem-like cells (GSCs) are recognized as a special population of GBM cells that contributes to tumorigenesis, radiochemoresistance, and recurrence [6-9]. Developing new therapeutic drugs combined with conventional therapy is strongly needed for GBM patients. GSCs are highly enriched for this adaptive potential and exhibit upregulation of the DNA damage response, an ability to preferentially utilize nutrients in response to harsh environmental conditions, and a general phenotype of resilience to therapy Several years ago, the discovery of a highly tumorigenic subpopulation of stem-like cells embedded within fresh surgical isolates of malignant gliomas lent support to a new paradigm in cancer biology—the cancer stem cell hypothesis.
