  12. “The ability to detect, through imaging, the molecular changes associated with a tumor cell will improve our ability to detect and stage tumors, select appropriate treatments, monitor the effectiveness of a treatment, and determine prognosis.” Ellen Feigal (MD, Acting Director, Division of Cancer Treatment and Diagnosis, National Cancer Institute, USA) Direct approaches.e.g., Monoclonal antibody targeting of a particular enzyme (e.g., hexokinase) with an enzyme-specific probe (e.g. deoxyglucose), using nuclear medicine  PET Biomarker approaches. Molecular indicator of a specific biological property; to monitor down-stream effects of changes in specific molecular-genetic pathways in diseases Indirect approaches. Imaging a reporter-gene using probes (e.g. transgene HSV1-tk) – to develope gene-therapies, visualization of regulation of gene-expression and intracellular protein-protein interactions Microarray Imaging Informatics WP5: Methods, Technologies & Tools (2nd year) D13:BMI &(Medical) Molecular Imaging • Key criteria : • High affinity probes with reasonable pharmacodynamics; • The probes to overcome biologic delivery barriers (vascular, cell membrane); • Use of amplification strategies (chemical or biologic); • Availability of sensitive, fast, high-resolution imaging techniques.
