Biochemical kinetics model of DSB repair and induction of gamma-H2AX foci by non-homologous end joining.
We developed a biochemical kinetics approach to describe the repair of double-strand breaks (DSBs) produced by low-LET radiation by modeling molecular events associated with non-homologous end joining (NHEJ). A system of coupled nonlinear ordinary differential equations describes the induction of DSBs and activation pathways for major NHEJ components including Ku70/80, DNA-PKcs, and the ligase IV-XRCC4 heterodimer. The autophosphorylation of DNA-PKcs and subsequent induction of gamma-H2AX foc...Expand abstract
