2 Mar 2018 Using flow cytometry, we show here that phosphorylation at T2609 is faster in response to DSBs than gamma-H2AX. Furthermore, flow

Furthermore, the effect of hypothermia was investigated at the level of phosphorylated histone 2AX (gamma H2AX) foci, clonogenic cell survival and micronuclei

The purpose of the present study was to assess immediate DNA damage after exposure to low level of ionizing radiation by the flow cytometric method of gamma-H2AX. Here, measurements of γ-H2AX immunofluorescence by microscopy and flow cytometry were compared as rapid biodosimetric tools for whole and partial body exposures. View This Abstract Online; Flow cytometric detection of gamma-H2AX to evaluate DNA damage by low dose diagnostic irradiation. Med Hypotheses. 2018; 115:22-28 (ISSN: 1532-2777) Gamma H2AX (gammaH2AX) is the phosphorylated version of histone H2AX and is a marker for double-stranded breaks (DSBs) caused by DNA damage (1-4).

Here, we have further optimized our previously reported γ‐H2AX assay 23 in order to shorten the procedure and minimize variation. Figure 1A is a schematic representation of the flow cytometry (FCM)‐based γ‐H2AX assay. The gating strategy used to analyze the FCM files is outlined in Figure 1B. γ-H2AX detection by flow cytometry in human embryonic fibroblasts.

In this way, phosphorylated H2AX promotes DNA repair and maintains genomic stability and thus helps prevent oncogenic transformations.

Bourton et al., 2011 have recently demonstrated using nonimaging flow cytometry, that in peripheral blood lymphocytes (PBL) derived from radiotherapy patients that experienced severe acute and delayed normal tissue toxicity, there was a persistence of γ-H2AX foci following exposure to 2 Gy gamma radiation.

In this study, we established a flow cytometry (FCM) system for measuring radiation-induced phosphorylated histone H2AX (gammaH2AX) in cultured human T lymphocytes to evaluate individual radiation sensitivity in vitro. At present, flow cytometry is the most rapid method for detection of DSBs and cell viability. In this chapter, we provide our experience and methodological modification of flow cytometry protocol for the detection of γ-H2AX, a well-known marker of DSBs, in fixed mammalian fibroblasts. The objective of the present study was to develop a rapid, high-throughput γ-H2AX assay based on imaging flow cytometry (IFC) using the ImageStream® X Mk II (ISX) platform to evaluate DNA double strand break (DSB) repair kinetics in human peripheral blood cells after exposure to ionizing irradiation. In contrast, flow cytometry allows simple detection of gamma-H2AX in a large number of cells (31). Several reports show that the level of gamma-H2AX as detected by flow cytometry correlates well with the number of DNA strand breaks, to the level of cell death and radiosensitivity (32–34). Histone H2A.X (H2AX) is a member of the histone H2A family which is one of the four core histones making up the nucleosome core particle.
