Mechanisms of Radioresistance in Cancer Stem Cells

Abstract: Cancer stem cells (CSCs) have recently been identified and characterized in many types of solid tumors and may contribute to treatment failure since they have been shown to be relatively resistant to conventional therapies. Recent data suggest that both intrinsic and extrinsic determinants confer radioresistance to CSCs through a variety of mechanisms including high DNA repair capabilities, lower cellular reactive oxygen species (ROS) levels, induced autophagy, activation of survival signaling pathways, and th… Show more

“…(6) CSCs may be located in hypoxic niches within tumors which would contribute to resistance to radiation. (139) There is raising evidence that polycomb group (PcG) proteins (discovered in Drosophila as epigenetic gene silencers) play an important role in cancer development and recurrence. PcG of proteins is composed of two multimeric protein complexes, which are the polycomb repressive complex (PRC)1 and PRC2.…”
