Imaging Matrix Metalloproteinase Activity Implicated in Breast Cancer Progression

Methods Mol Biol. 2016:1406:303-29. doi: 10.1007/978-1-4939-3444-7_25.

Abstract

Proteolysis has been cited as an important contributor to cancer initiation and progression. One can take advantage of tumor-associated proteases to selectively deliver imaging agents. Protease-activated imaging systems have been developed using substrates designed for hydrolysis by members of the matrix metalloproteinase (MMP) family. We presently describe approaches by which one can optically image matrix metalloproteinase activity implicated in breast cancer progression, with consideration of selective versus broad protease probes.

Keywords: Collagen; Imaging agent; Matrix metalloproteinase; Near infrared; Triple-helix.
