FIGURE 7.
Effects of HMPSNE (100 µM) alone or in combination with doxorubicin (1 µM) on CD44 expression in MDA-MB-231 cells. (A) qRT‒PCR was performed, and the results were normalized to those of B-actin as an internal control. The data are shown as the means ± SEMs of three independent experiments: *P < 0.05, **P < 0.01. (B) Representative curves for flow cytometry analysis of TNBC cells before and after treatment. The overlay shows CD44 expression upon treatment with doxorubicin and HMPSNE in comparison with the unstained control (orange), which was used to establish baseline autofluorescence and gating thresholds. The median fluorescence values with relative standard deviations are shown in the table under the figure. This experiment was repeated three times.
