Elevation of intracellular calcium concentration in MDA-MB-231 or MCF-7 cells following temporin-1CEa treatment in either a calcium-containing solution (A-B) or calcium-free solution (C–D).

<p>Fluo3-AM green fluorescence was used for evaluation of the cytosolic calcium levels. Each bar represents the mean value from three determinations with the standard deviation (SD). Data (mean ± SD) with asterisk significantly differ (*p<0.05; **p<0.01) between treatments.
