The Phenoxyphenol Compound 4-HPPP Selectively Induces Antiproliferation Effects and Apoptosis in Human Lung Cancer Cells through Aneupolyploidization and ATR DNA Repair Signaling

Figure 1

The inhibitory effect of compounds on the long-term proliferation of NSCLC cells. NSCLC H1299 cells and BEAS-2B human bronchial epithelial cells were treated with the indicated concentrations (from 0.5 to 10 μM) of tested compounds for 14 days. Afterward, the cells were paraformaldehyde-fixed and stained with crystal violet. (a) Chemical structures of 4-HPPP and its structural analogs. (b) Representative results of the colony formation of H1299 and BEAS-2B cells following compound treatment. (c) The quantitative results of (b) were statistically analyzed with one-way ANOVA. ; .
