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. GBMs are highly resistant to treatment for a number of reasons that will be discussed in more detail below. Glioblastoma multiforme (GBM) is an aggressive brain tumor that is resistant to all known therapies.

The emerging role of cancer stem cells in tumor Glioblastoma is an aggressive and heterogeneous tumor in which glioblastoma stem cells (GSCs) are at the apex of an entropic hierarchy and impart devastating therapy resistance. The high entropy of GSCs is driven by a permissive epigenetic landscape and a mutational landscape that revokes crucial cellular checkpoints. In response to DNA damage, normal cells activate the DNA damage response (DDR), utilizing a variety of DNA damage sensing and repair pathways (e.g., base excision repair, nucleotide excision repair, homologous recombination, nonhomologous end-joining, mismatch repair, direct reversal) to maintain genomic integrity, whereas the inability to repair DNA damage leads to apoptosis . 2017-10-09 · Glioma stem cells promote radioresistance by preferential activation of the DNA damage response.

Notch Pathway Does Not Alter DNA Damage Response of Glioma Stem Cells The DNA damage checkpoint response plays a critical role in cellular response to radiation [ 48 , 49 ]. Our previous study showed that increased activation of the DNA damage response is implicated in radioresistance of the glioma stem cells [ 7 ].

Potential therapies that modulate or target cancer stem cells are also reviewed. 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 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 JN. Nature.

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. 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). Thus, tumours sur- Glioma stem cells promote radioresistance by preferential activation of the DNA damage response 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 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.

Radiation-induced EV export of miR-603 simultaneously promoted the CSC state and up-regulated DNA repair to promote acquired resistance. These effects were abolished by exogenous miR-603 expression, suggesting potential for clinical translation. 2019-02-05 · Glioma stem cells promote radioresistance by preferential activation of the DNA damage response Nature , 444 ( 2006 ) , pp. 756 - 760 CrossRef View Record in Scopus Google Scholar In this study, CD133 (a marker of brain cancer stem cells) and nestin were co-expressed in GSCs isolated from GCs. The percent of CD133+ cells in GSCs and GCs were >80 and 2%, respectively. Significantly more GSCs survived following 2, 4, 6 and 8 Gy IR than GCs. IR kills cancer cells primarily through DNA double-strand breaks (DSBs). DNA damage checkpoint response of glioblastoma stem cells through NBS1 that GBM stem cells (GSCs) display a preferential activation of DNA damage promote radioresistance through preferential activation of the DNA damage . 24 Mar 2021 Glioma stem cells promote radioresistance by preferential activation of the DNA damage response.

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.
