Article Snippet: Membranes were blocked in 5% non-fat milk in TBST for 1 h at RT and incubated overnight at 4°C with primary antibodies against p-ATM (1:2000; Cell Signaling Technology, 5883), p-p53 (1:1000; Cell Signaling Technology, 9284) and p53 (1:1000; Cell Signaling Technology, 9282). α-Tubulin (1:1000, Sigma Aldrich, T7451) or Vinculin (1:1000, Sigma Aldrich, V9131) were used as loading controls.

Figure Lengend Snippet: Monoher interacts with p53. Biomolecular interactions of monoHER with wild-type p53 (A) and mutant p53 (B). Docking scores are indicated at the bottom of the image. Representative Western blots and quantification (E) of the CETSA experiment with cell lysates of MCF7 cells, which were treated with DMEM (C) or monoHER (D). Data are presented as mean ± SEM from three independent experiments.
