ATLANTA, April 1 /PRNewswire/ --
"The traditional treatment philosophy of 'one size fits all' is quickly becoming obsolete," says George Daneker, MD, the Medical Director of Oncology Research at Saint Joseph's Hospital and co-principal investigator of the study. "No two individuals are alike nor are two cancers; each is unique based on genetic and protein makeup."
Working with John McDonald, PhD, Chair of the School of Biology at
Dr. McDonald, recognized as a world authority in molecular genetics and genomics and Dr. Daneker, a surgical oncologist with an extensive background in basic and translational research, are applying state-of-the-art technologies toward identifying aberrant molecular and cellular mechanisms. Using microarray technology, gene expression patterns in pancreatic tumor tissue are compared with those present in the normal pancreas tissue. Microarray technology allows examination of more than 20,000 genes in a single experiment. Differences in the expression of genes encoding cellular proteins are of special interest with regard to the development of specific treatments.
There is also interest in the molecular basis of chemotherapy resistance. Some tumors respond very well to chemotherapy while others acquire resistance. By comparing the gene expression patterns in tumors that have become resistant to chemotherapy with patterns of these same tumors prior to chemotherapy, the research team hopes to identify the genes which mediate resistant. Identification of the mechanisms of resistance could lead to the development of treatment strategies that overcome the resistant pathways, making all tumors more responsive to treatment.
The research efforts will also focus on screening and early detection. By using a powerful analytical tool called mass spectrometry, coupled with data analysis using a "super-computer," the group hopes to identify patterns of molecular expression unique to cancer patients. This can lead to a sensitive screening test that only requires one drop of blood to run.
"Georgia Tech has the most advanced technology and the scientists who can help move these 'bench' research projects closer to 'bedside' treatments for patients at a very rapid rate," says Daneker. "Saint Joseph's brings the clinical expertise to take the treatments directly to the patient faster. It's a very unique partnership that facilitates rapid discovery and satisfies both our missions to bring the best treatments to patients in the quickest, safest way."
