IntegriSense™ 750 is a targeted fluorescent imaging agent comprising a potent, selective non-peptide small molecule integrin avb3 antagonist and a near- infrared (NIR) fluorochrome. IntegriSense 750 has a shorter half life in tissue than IntegriSense 680. IntegriSense 750 washes out of tissues in ~ 96 hours to permit more frequent reinjection of the agent in longitudinal studies. This agent has been developed to enable in vivo visualization and quantification of integrin avb3 in tumor cells as well as in neovasculature, to monitor tumor growth, tumor angiogenesis, and treatment efficacy.

Current means of measuring disease in preclinical models of atherosclerosis include ex vivo assessment of disease tissues post-mortem and non-invasive imaging primarily of structural and anatomic features of lesions, in vivo. A non-invasive, quantitative means of imaging known biologic profiles associated with atherosclerotic disease, in vivo, would enable a robust additional understanding and analysis of disease progression and therapeutic response in research and drug development. We report the utility of the near infrared (NIR) protease-sensing, ProSense® 750 Fluorescent Pre-clinical Imaging Agent, in combination with the FMT® 2500 Quantitative Pre-clinical Imaging System for the non-invasive quantitative measurement of atherosclerotic disease biology and related response to therapy in apolipoprotein (apo) E-deficient mice in vivo. FMT (Fluorescence Molecular Tomography) imaging measured significant increases in aortic region protease activity with a range of values that were comparable to the range seen in the ex vivo aortic arches assessed by fluorescence reflectance imaging (FRI).
Epifluorescence (2D) imaging of superficially,implanted mouse tumor xenograft models offers,a fast and simple method for assessing tumor,progression or response to therapy. This approach,for tumor assessment requires the use of near,infrared (NIR) imaging agents specific for different,aspects of tumor biology, and this Application,Note highlights the ease and utility of multiplex,NIR fluorescence imaging to characterize the,complex biology within tumors growing in a living,mouse. IntegriSense™ 750 detects avb3 integrin,expression, BombesinRSense™ 680 detects the upregulation of bombesin receptor,(associated with tumor proliferation), Transferrin-Vivo™ 750 detects increases in,transferrin receptor (due to increased iron metabolism), MMPSense® 680 is activated,by disease-related matrix-metalloproteases (secreted by tumor cells and tumor,associated macrophages), and ProSense® 750EX detects increases in cathepsin,activity (elevated in lysosomes of tumors and inflammatory cells). OsteoSense® 680,a bone turnover imaging agent, was used as a non-tumor imaging control. These,and multiple other PerkinElmer imaging agents, can be used to characterize tumor,biology, and in this set of studies the data shows that two different tumors, HeLa,(cervical cancer) and 4T1 (breast cancer), can differ in their pattern of labeling,intensities for six distinct biological imaging agents. Such an approach is likely to,prove valuable for the full biological characterization of tumors during progression,metastasis, or response to treatment.
