Copper distribution in breast cancer cells detected by time-of-flight secondary ion mass spectrometry with delayed extraction methodology
Artikel i vetenskaplig tidskrift, 2018

Copper (Cu) is an essential transition metal ion that acts as a cofactor in many key enzymes. Cu is also needed for several hallmarks of cancer, and many copper-binding proteins are upregulated in various cancers. However, Cu-dependent cellular mechanisms and molecular pathways involved in cancer progression are not known. Fundamental to a better understanding of such phenomena is the investigation of the Cu subcellular distribution in cancer cells. The authors here show that Time-of-Flight Secondary Ion Mass Spectrometry combined with delayed extraction can be successfully applied to probe Cu localization in fixed MDA-MB-231 breast cancer cells providing subcellular resolution. Interestingly, the authors find Cu to be accumulated at nuclear regions of the cancer cells. Published by the AVS.
