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. 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 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). The mechanisms underlying tumour radioresistance have remained elusive. 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 population doubling time was … 2018-05-21 · Previous studies showed that, preferential activation of the DNA damage checkpoint and enhanced DNA repair capacity in gliomas lead to radioresistance [9, 14, 15].

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 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.
