Figure 6From: Inhibition of breast cancer cell proliferation in repeated and non-repeated treatment with zoledronic acidApoptotic cells evaluated by TUNEL assay. Data represent the mean ± SD of three independent experiments. Error bars represent the mean ± SD. *p <0.05, ** p <0.01. A) Western blot data about modulation of apoptotic markers after the two treatment schedules in the 4 breast cancer cell lines. B) Percentage of cells in apoptosis. Data represent the mean ± SD of three independent experiments. *p <0.05, **p <0.01.Back to article page
