WebFirst, assuming that events (i.e., ionization and excitation) potentially induce DNA strand breaks, we scored the number of events in a water cube (5.03 × 5.03 × 5.03 nm3) along electron tracks. Second, we obtained the relationship between the number of events and the foci size experimentally measured by the γ-H2AX focus formation assay.

Imaging DNA double-strand breaks — are we there yet? - Nature
WebPurpose: Phosphorylated histone H2AX (gamma H2AX) serves as a biomarker for formation of DNA double-strand break repair complexes. A quantitative pharmacodynamic immunofluorescence assay for gamma H2AX was developed, validated, and tested in human tumor xenograft models with the use of clinically relevant procedures. WebApr 23, 2024 · DNA double-strand break (DSB) induction and repair have been widely studied in radiation therapy (RT); however little is known about the impact of very low exposures from repeated computed tomography (CT) scans for the efficiency of repair. In our current study, DSB repair and kinetics were investigated in side-by-side comparison … WebOct 1, 2013 · The γH2AX response contributes to the repair of double strand breaks encountered in a variety of different contexts, including those induced by ionizing … gratuity under labour act 2006
