Figure 3From: Quantitative measurement of alterations in DNA damage repair (DDR) pathways using single cell network profiling (SCNP) Analysis of etoposide inducible SCNP DDR readouts in cell lines with characterized DDR pathway deficiencies. (A) Flow plots illustrate the gating scheme to identify live (Aqua-) non-apoptotic, healthy (cPARP-) cells for analysis of DDR responses. (B) Flow plot examples of p-DNA-PKcs, p-H2AX, p-ATM and p-BRCA1 induction in ATM+/+, ATM+/- and ATM-/- cell lines (Red: 2 h unstimulated, Blue: 2 h etoposide treated, (30 μg/mL)). (C) Shown are Log2Fold change in levels of intracellular readouts following 2 hr etoposide treatment. DDR readouts: p-ATM, p-BRCA1, p-DNA-PKcs, p-53BP1, p-p53, p-Chk2, and p-H2AX. Cell lines (Cell line panel 1, Materials and methods) are coded by color. ATM-/- cell lines (grey and back dots) consistently show lower induced values for all modulated DDR readouts measured. In contrast, ATM +/- cells (magenta dots) shows slightly lower DDR readouts vs. ATM +/+ cells for some (p-ATM, p-DNA-PKcs) but not all reaoduts in these conditions.Back to article page
