doi: 10.1172/jci.insight.174329
Figure Lengend Snippet: ( A ) Dose-response curve of SUM149 cells treated with rigosertib from the high-throughput screen described in Figure 1. Data are the mean ± SD of triplicate samples. ( B – E ) Dose-response curves for rigosertib treatment of HCC1806 ( B ), SUM149 ( C ), A549 ( D ), and Calu6 ( E ) cells growing in RPMI versus HPLM. Data are the mean ± SD of triplicate samples. ( F ) Representative Western blot of phosphorylated histone H3 in HCC1806 cells treated with 150 nM rigosertib in RPMI versus HPLM. ( G and H ) Cell cycle analysis of HCC1806 cells treated with 150 nM commercial-grade rigosertib in RPMI ( G ) and HPLM ( H ). ( I ) Cell death analysis of HCC1806 cells treated with 200 nM commercial-grade rigosertib in RPMI versus HPLM. PI, propidium iodide. Cell death and cell cycle data are the means ± SD of triplicate samples. * indicates P < 0.05 by unpaired 2-tailed t test.
