Abstract

Microenviroment hypoxia is one of the common phenomenon in cancer,studies have indiacat-ed that hypoxia induces genetic instability via activating many DNA danlage-repair signal pathways,which asso-ciates with tumor invasion and resistance and chemi-radiotherapy resistivity.Here,we overview three main DNA damage-repair pathways:mismatch repair,homologous recombination and non-homologous end joining,and how hypoxia influences their mechanisms.
