Rapid sorting and auxiliary evaluation of malignant breast tumors by accurate imaging analysis of metastasis-related biomarker.

ABSTRACT: Accurate differentiation of benign and malignant breast tumors is paramount for establishing schemes of breast cancer treatment and prognosis. Here we report a near-infrared (NIR) fluorescence probe (YF-1) with the overexpressed cathepsin C (CTSC) in metastatic breast tumors as the detecting substrate. This probe allows accurate identification of malignant tumor tissue specimens among tumor tissue specimens with unknown properties in a blind study. Importantly, a series of visible to NIR CTSC-activated fluorescence probes based on the same strategy realize effective identification of malignant tumor tissues, suggesting that CTSC could be the specific identification substrate of malignant breast tumors. Furthermore, a hydrophilic PEG moiety is coupled into YF-1, producing another CTSC-activ
