Effect of microbial siderophores on mammalian non-malignant and malignant cell lines.


PMID 28274224

Abstract

Iron is a vital nutrient for all cells, and malignant cells have a higher requirement for the metal due to their rapid multiplication. Bacterial siderophores can be used to reduce free ferric ion concentration from the cellular environment. In the present study, we have evaluated effect of three siderophores - exochelin-MS, mycobactin S and deferoxamine B on the proliferation of mammalian cell lines using MTT assay. These siderophores caused a significant decrease in the viability of malignant cells, without significantly affecting non-malignant cells. Based on these results, we suggest that iron-chelation therapy could be explored as an adjunctive therapeutic option against cancer along with other therapies.
