Les kinases de la famille PI3 ( Ataxie télangiectasie mutée , ATR et ADN-PKcs) sont responsables de cette phosphorylation, en particulier ATM. The gamma-H2AX Assay for Genotoxic and Nongenotoxic Agents: Comparisonof H2AX Phosphorylation with Cell Death Response. Teodora Nikolova, Mirek Dvorak, Fabian Jung, Isabell Adam, Elisabeth Krämer, Aslihan Gerhold-Ay, Bernd Kaina Gamma H2AX and its phosphorylation can be detected through western blotting and immunofluorescence, serving as a biomarker for DSB frequency (1-4). Ataxia telangiectasia mutated (ATM) is considered a key protein for H2AX phosphorylation (1-4). 2007-01-23 · Phosphorylated on Ser-140 (to form gamma-H2AX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, and may also occur during meiotic recombination events and immunoglobulin class switching in lymphocytes. While the suppression of DNA replication aphidicolin prevented the induction of H2AX phosphorylation by UV in most S phase cells, it had no effect on a small cohort of cells that appeared to be entering S-phase, that expressed very high levels of γH2AX.

Gamma h2ax phosphorylation

The aim of our study was to determine whether phosphorylation of histone H2AX can be used as an indicator of received dose of gamma radiation after whole-body irradiation of rats. Wistar rats were irradiated by 1-10 Gy of gamma radiation by 60Co source. Value LD50/60 was 7.37 (4.68-8.05) Gy. 2014-07-04 · Background Chk1 inhibitors are currently in clinical trials in combination with a range of cytotoxic agents and have the potential to potentiate the clinical activity of a large number of standard of care chemotherapeutic agents. Utilizing pharmacodynamic biomarkers to optimize drug dose and scheduling in these trials could greatly enhance the likelihood of clinical success. Methods In this The phosphorylation of thousands of H2AX molecules forms a gamma-H2AX focus in the chromatin flanking the DSB site that can be detected in situ. We analyzed gamma- H2AX focus formation in both directly irradiated cells as well as in un-irradiated "bystanders" in close contact with irradiated cells.

H2AX (H2A histone family member X) helps to maintain genome stability.

Here, we show that protein … H2AX phosphorylation and its role in DNA damage response upon phosphorylation H2AX became critical player in DNA damage response. Activity of 𝛾 H2AX could be summarized to following main points: accumulation of DNA damage signaling and repair proteins at DSBs The generation of DSBs triggers the relocalization of many DNA damage response (DDR) proteins such as MRE11/NBS1/RAD50, MDC1 Phosphorylation of many repair proteins has been shown to be important for their recruitment to DNA damage-induced intra-nuclear foci. Further, phosphorylation of H2AX (gamma-H2AX) has been shown to be important for either the recruitment or stable retention of DNA repair proteins to these intra-nuclear foci. H2AX becomes phosphorylated on serine 139, then called γH2AX, as a reaction on DNA double-strand breaks (DSB).
