G0S2 regulates glioma cell DNA repair in response to IR. Emerging evidence suggests that activation of DNA repair is an important factor for glioma radiation resistance [4, 5]. We hypothesize that G0S2 also regulates glioma radiation response through activation of DNA repair.

Here we show that cancer stem cells contribute to glioma radioresistance through preferential activation of the DNA damage Here we show that 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 cells expressing CD133 (Prominin-1), a marker for both neural stem cells and brain cancer stem cells, is enriched after radiation in gliomas. In both cell culture and the brains of immunocompromised mice, CD133-expressing glioma cells survive ionizing radiation in increased proportions Here we show that 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 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 cancer stem cells contribute to glioma radioresistance through preferential activation of the DNA damage checkpoint response and an increase in DNA repair capacity.
Glioma stem cells (GSCs) have a high capacity for self-renewal, invasion, and survival. How they communicate with each other to survive and maintain their identity is not clear. Man et al. now show that GSCs have co-opted a neurodevelopmental program to activate Rac1 to promote defining features of GSCs.

We have examined DNA repair in five stem and nonstem glioma cell lines. The population doubling time was … Comparative analysis of DNA repair in stem and nonstem glioma cell cultures. It has been reported that cancer stem cells may contribute to glioma radioresistance through preferential activation of the DNA damage checkpoint response and an increase in DNA repair capacity. We have examined DNA repair in five stem and nonstem glioma cell lines.

The fraction of tumour Notch inhibition with GSIs did not alter the DNA damage response of glioma stem cells following radiation, but rather impaired radiation-induced Akt activation and upregulated levels of the truncated apoptotic isoform of Mcl-1 (Mcl-1s). Taken together, our results suggest a critical role of Notch to promote radioresistance of glioma stem cells.

Nature 2006; 444 : 756–760. 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.
