Rhein Induces Apoptosis in Human Breast Cancer Cells

Figure 1

Expression of HER2/neu in human breast cancer cells. Vector control MCF-7 cells (MCF-7/VEC) and HER2-overexpressing MCF-7 cells (MCF-7/HER2) were harvested, and cell lysates were analyzed by Western blotting with anti-HER2 and anti-β actin antibodies.
