Molecular imaging of hypoxia.
A wide variety of imaging approaches have been developed in the past few decades for monitoring tumor oxygenation and hypoxia in vivo. In particular, nuclear medicine has seen the development of several radiolabeled hypoxia markers and is the preferred method for imaging of tumor hypoxia. Hypoxia imaging is increasingly being used in the clinical setting and is progressing from a mere detection...
متن کاملMolecular Probes for Imaging of Hypoxia in the Retina
Hypoxia has been associated with retinal diseases which lead the causes of irreversible vision loss, including diabetic retinopathy, retinopathy of prematurity, and age-related macular degeneration. Therefore, technologies for imaging hypoxia in the retina are needed for early disease detection, monitoring of disease progression, and assessment of therapeutic responses in the patient. Toward th...
متن کاملI-55: Molecular Imaging Overview
Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...
متن کاملDesign, Synthesis and Labeling of Tripeptide Derivatives with 99mTc as Hypoxia Imaging Agents
Background: Many diseases, including cancer, ischemia and tumors show degrees of tissue hypoxia.Therefore, it is useful to detect tissue hypoxia with compounds that can penetrate and remain in hypoxic cells in order to diagnose cancer at early stages. Peptides with low molecular weight, susceptible to redox environment, with easier penetration into tissues and low antigenic characteristics are ...
متن کاملNoninvasive molecular imaging of hypoxia in human xenografts: comparing hypoxia-induced gene expression with endogenous and exogenous hypoxia markers.
Tumor hypoxia is important in the development and treatment of human cancers. We have developed a novel xenograft model for studying and imaging of hypoxia-induced gene expression. A hypoxia-inducible dual reporter herpes simplex virus type 1 thymidine kinase and enhanced green fluorescence protein (HSV1-TKeGFP), under the control of hypoxia response element (9HRE), was stably transfected into ...
