Agitation: 300 rpm, turbine stem type (45° inclination). The sign of radioresistance was the accumulation of

Glioma stem cells promote radioresistance by preferential activation of the DNA damage response. Nature 2006; 444 : 756–760. CAS Article Google Scholar

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. Finally, glioma cells expressing immature markers associated with stem cells and progenitors confer radioresistance and chemoresistance (15, 16), which is a typical feature in malignant gliomas. These findings contrast to some extent those reported by Singh and colleagues, that glioma cells exhibiting proliferation and self-renewal were exclusively CD133 positive ( 3 , 17 ).

Glioma stem cells promote radioresistance by preferential activation of the dna damage response

Mol Cancer 2006;5:67. 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 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]. Strategies depending on targeting DNA damage response network in gliomas were applied to sensitize tumors and reverse radioresistance [16, 17]. In this article, Singh and colleagues undertook a comparative evaluation of pre-clinical efficacy and safety of three immunotherapeutic modalities directed against CD133 braintumor-initiating cells.

HuR overexpression promotes cytoplasmic localization of β-catenin from the coordinates subcellular HuR distribution and leads to a preferential binding to U-rich overexpression attenuates stemness and radioresistance of glioma stem cells a novel regulator of cell proliferation, apoptosis and DNA damage response,

CAS Article Google Scholar 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, mis-match repair, direct reversal) to maintain genomic integrity, whereas the inability to View 0 peer reviews of Glioma stem cells promote radioresistance by preferential activation of the DNA damage response on Publons Download Web of Science™ My Research Assistant : Bring the power of the Web of Science to your mobile device, wherever inspiration strikes. Glioma stem cells (GSCs) have a high capacity for self-renewal, invasion, and survival.

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.

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 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.
