Modifications of disulfide bonds in breast cancer cell migration and invasiveness.

ABSTRACT: Cancer metastasis involves the adhesion of cancer cells to the endothelium. This process can be mediated by integrins which are surface receptors responsible for interactions with ECM proteins. Integrins β1 and αVβ3 represent factors are involved in cancer progression and metastasis. Activation of integrins can be promoted by thiol-disulfide exchanges initiated by Protein Disulfide Isomerase (PDI). The purpose of this study was to prove the involvement of disulfide rearrangements in the molecules of integrins in the course of cancer cell adhesion and migration through the endothelium. We present the evidence which proves that highly metastatic MDA-MB-231 breast cancer cell lines adhere to endothelial cells are more effective than non-invasive MCF-10A and MCF-7 cell lines and that the attac
