项目摘要

PROJECT 2: The emerging fields of genomics and proteomics have led to a better comprehension of the pathophysiology of cancer and the identification of novel signaling pathways. These pathways offer novel 'targets' (e.g. Akt, MEK, mTOR and Receptor Tyrosine Kinases) which has led to the development of 'lead molecules' designed to inhibit the signaling derived from these pathways. However, this poses a tremendous challenge for selecting and/or validating these targets and for broad profiling of lead molecules for candidate selection. Molecular imaging technologies have the potential to address these scientific and technological challenges. The overall goal of Project 2 is to develop strategies wherein activation or inhibition of key pathways in tumor formation as well as in the response of tumors to therapies can be non-invasive imaged. Since targeted therapies often lead to tumor cytostasis (Gl arrest), we will in Aim 1 develop and test a non-invasive reporter for proliferation (entry of cells to S-phase of the cell cycle from G1). This reporter will be used to investigate the efficacy of four targeted therapeutic agents (PTK 787, a receptor Tyrosine Kinase (PDGFR) inhibitor; Perifosine, an AKT inhibitor; CCI 779, an mTOR inhibitor and Cl 1040, a MEK inhibitor). In Aim 2 we will use a non-invasive reporter for apoptosis to test the hypothesis that while targeted therapies may not induce apoptosis as single agents, in combination with other targeted therapies or with traditional therapies induction of apoptosis will correlate with efficacy and enhanced tumor control. In Aim 3, we will develop a reporter for Akt function and use it to test the ability of PTK 787, Cl 779, Cl 1040 and Perifosine to inhibit Akt activity. Each of the three molecular imaging approaches will be validated using traditional "gold standard" measures of function of these pathways (e.g. Western blots, immunohistochemistry, kinase assays). We believe that studies proposed in Project 2, will result in the development of tools that will be invaluable in testing the efficacy of targeted therapeutic agents as well as in optimization of their dose, schedule and development of the most efficacious combination therapies. Pub. Health: Overall, this research effort will provide the rationale for initiation of clinical trials with combinations of molecularly targeted therapies for the treatment of malignant brain tumors. In addition, imaging biomarkers for early assessment of treatment response will be identified and validated which will lead to individualization of patient treatment.
