Colloidal silver has been used as an antimicrobial and disinfectant agent. However, there is scarce information on its antitumor potential. The aim of this study was to determine if colloidal silver had cytotoxic effects on MCF-7 breast cancer cells and its mechanism of cell death.
MCF-7 breast cancer cells were treated with colloidal silver (ranged from 1.75 to 17.5 ng/mL) for 5 h at 37°C and 5% CO2 atmosphere. Cell Viability was evaluated by trypan blue exclusion method and the mechanism of cell death through detection of mono-oligonucleosomes using an ELISA kit and TUNEL assay. The production of NO, LDH, and Gpx, SOD, CAT, and Total antioxidant activities were evaluated by colorimetric assays.
Colloidal silver had dose-dependent cytotoxic effect in MCF-7 breast cancer cells through induction of apoptosis, shown an LD50 (3.5 ng/mL) and LD100 (14 ng/mL) (*P < 0.05), significantly decreased LDH (*P < 0.05) and significantly increased SOD (*P < 0.05) activities. However, the NO production, and Gpx, CAT, and Total antioxidant activities were not affected in MCF-7 breast cancer cells. PBMC were not altered by colloidal silver.
The overall results indicated that the colloidal silver has antitumor activity through induction of apoptosis in MCF-7 breast cancer cell line, suggesting that colloidal silver might be a potential alternative agent for human breast cancer therapy.
Colloidal silver is a common substance used by the Mexican people for disinfecting foods and water for their consumption, and at this time there is not a report on potential secondary effects related to this treatment; this also agreed with a recent study in mice performed in our laboratory, where colloidal silver was provided in the water at 10- and 50-fold higher concentrations than the recommended by the manufacturer during one year without finding any alterations in the evaluated parameters (fertility, birth, and tumors development)
There you have it folks.. Colloidal Silver = positive results for breast cancer. Google searches reveal HUNDREDS more testimonials bycolloidal silver users with regards to other types of cancers and illnesses.
