Figure Protein expression of nucleophosmin/B23 (Nucl./B23), STAT3, tubulin, and c-Myc were determined by western blot analysis. MCF-7 and MDA-MB-231 were treated without or with cucurbitacin B for 48 hrs. After incubation, total proteins were extracted and performed western blotting to analyze the expression levels of nucleophosmin, STAT3, tubulin, and c-Myc gene. This bar graph represents the densitometric analyses of expression of nucleophosmin/B23 (Nucl./B23), STAT3, tubulin, and c-Myc relative to the untreated control. * P < 0.05 (treated vs untreated control).
