Figure Lengend Snippet: Figure 1. Establishment of BETi-resistant cells from NCI-H1975 cells. A, A schematic diagram of the establishment of ABBV-075–resistant variants. B, The IC50 values of ABBV- 075 in the parental cells and the resistant variants were determined by SRB assays. IC50 refers to the concentrations of ABBV-075 that caused 50% inhibition of cell proliferation after 72-hour treatment. C, Cell morphology of parental cells and resistant variants (RMIX, R1, R5, R6, and R9) was imaged under an Olympus CKX53 phase contrast microscope using a 10objectivelens.Bars,100 mm. D, IC50 values of four BETis including ABBV-075, (þ)-JQ1, OTX015, and N2817 in parental cells and resistant variants (RMIX, R1, R5, R6, and R9) were detected by SRB assays after 72-hour treatments. E, Growth rates of indicated cells measured during 1–7-day incubation. Cell viability on each day was detected using CellTiter-Glo. Relative OD values were obtained by comparing the OD values on days 2–7 to that on day 1 and OD values of day 1 were normalized as one. Data from three independent experiments, if applicable, were expressed as mean SD (error bar); , P < 0.05.
