Figure Lengend Snippet: NPM1 redistribution with Chk1 and Chk2 inhibition at 24 h drug treatment. Cells were treated with 10 μM platinum compounds or 5 nM of ActD for 24 h in the presence or absence of Chk1i (1.0 mM) or Chk2i (0.4 μM) in A549 ( A ) or U-2 OS ( B ) cell lines. NPM1 immunofluorescence distribution was then quantified . Each point is the average CV value and SD for three biological replicates. Representative cell images of cells treated with 1 or 2 in the presence of Chk1i, Chk2i, or no inhibitor for each cell line are shown with NPM1 ( green ). ∗∗∗ p < 0.001, ns = p > 0.1.
Article Snippet: ATM inhibitor (KU-55933, MedChemExpress) treatment was conducted at 10 μM, ATR inhibitor (AZD6738, MedChemExpress) treatment was conducted at 2.5 μM, Chk1 inhibitor (caffeine) treatment was conducted at 1 mM, and Chk2 inhibitor (BML-277, MedChemExpress) treatment was conducted at 0.4 μM.
Techniques: Inhibition, Immunofluorescence
