In vitro therapy investigation for breast cancer by B13-chloroquine application

Cancer disease still remains to be strong treat for public health. New treatment approaches and agents with low side effects are needed for the treatment of breast cancer. Based on these, herein was aimed to investigate the cytotoxicity of a combination comprising a ceramidase inhibitor (B13) and an autophagy inhibitor (chloroquine) on human breast cancer cell line. The antiproliferative activity was tested by Sulforhodamine B and ATP viability assays. For ultrastructural and morphological changes and apoptotic signs of MCF-7 cells were used TEM and confocal microscopy techniques. Results showed the high cytotoxic and antiproliferative activities of the combination along with the ultrastructural and morphological changes indicating apoptosis. B13+Chloroquine combinations found to be effective on inducing cell death on MCF-7 cells and antiproliferative and cytotoxic effects on cells. Consequently, the new combination is suggested as good candidate for further investigations to be an anti-cancer agent.
