RETRACTED ARTICLE: The toxicity and therapeutic effects of single-and multi-wall carbon nanotubes on mice breast cancer

Abstract Herein, we have investigated the toxicity of SWCNTs and MWCNTs in vitro and in vivo , and assessed their therapeutic effects on a typical animal model of breast cancer in order to obtain: first, the cytotoxicity effects of CNTs on MC4L2 cell and mice, second the impact of CNTs on ablation o...

Description
Summary:Abstract Herein, we have investigated the toxicity of SWCNTs and MWCNTs in vitro and in vivo , and assessed their therapeutic effects on a typical animal model of breast cancer in order to obtain: first, the cytotoxicity effects of CNTs on MC4L2 cell and mice, second the impact of CNTs on ablation of breast tumor. CNTs especially SWCNTs were toxic to organs and induced death at high dosages. In this case, some of the liver cells showed a relative shrinkage which was also confirmed by Annexin test in MC4L2 cells. Moreover, CNTs decreased the tumor volume. BCL2 gene was down-regulated, and BAX and Caspase-3 were also up-regulated in the treated groups with CNTs. As a result, CNTs especially MWCNT in lower dosages can be used as a promising drug delivery vehicle for targeted therapy of abnormal cells in breast cancer.
