Viability decrease (100% of proliferation in untreated condition—% of proliferation for each treatment condition) of A549 (lung) and MCF-7 (breast) cancer cells and 16HBE14o- (bronchial) and MCF10A (mammary gland) non-cancer cells when incubated with different concentrations of CT-p19 peptide (0 to 100 μM) over 48 h. Untreated condition (control) consisted of cells incubated with medium only. Values represent the means ± SD, and each condition had at least n = 3. *, **, ***, **** and ns denote significant differences of p < 0.1, p < 0.01, p < 0.001 and p < 0.0001 and differences that were not statistically significant, respectively, when comparing control with treatments.
