Fig. 13From: A purified and lyophilized Pseudomonas aeruginosa derived pyocyanin induces promising apoptotic and necrotic activities against MCF-7 human breast adenocarcinomaCaspase-3 dependent apoptotic activity of pyocyanin in MCF-7 cells. A mRNA expression of caspase-3 was determined using real-time PCR assays. B, C The protein level of caspase 3 in MCF-7 cells treated with pyocyanin (IC50) was determined using Western blot assays, and β-Actin was used as an internal control. The error bars indicate standard deviations. The asterisks represent statistical significance (P < 0.05)Back to article page
