DNA Repair Research for Cancer Therapy at the University of Arkansas for Medical Sciences
Wolfe Lab | Translational Radiation Oncology
The Wolfe Lab is an interdisciplinary research lab that spans the interface between DNA repair and radiation therapy in deadly cancers. The lab studies aspects of oncogenic DNA repair regulation, homologous recombination dynamics, and radiation mouse models of human cancer.
Research Program
The Wolfe Lab investigates DNA repair pathways leading to treatment resistance to radiation therapy, novel DNA damage radiation biomarkers, and the development of novel DNA repair targets to improve responses to radiation therapy. We are interested in understanding the molecular drivers of radiation resistance. Our main disease of focus is pancreatic cancer. We utilize genetic and proteomic approaches to address the fundamental mechanisms of genetic alterations in cancer cells, resulting in heightened DNA repair leading to radiation resistance. We have developed relevant in vitro and in vivo models of human cancer that mimic the disease phenotype in the patients.
The projects that we currently are working on in the lab are:
-
Role of DNA repair proteins in Radiation Resistance in KRAS mutant Pancreatic Cancer. DNA repair is critically important for maintaining the radioresistant phenotype of KRAS mutant pancreatic cancer. We are studying ways to target upregulated DNA repair pathways that can enhance tumor control and clinical outcomes through “biological dose escalation” to the tumor while sparing the surrounding critical structures.
-
Translational model of radiation therapy in pancreatic cancer. We have developed a clinically relevant pancreatic pre-clinical model to understand better the role of DNA repair on therapeutic response. We use a Small Animal Radiation Research Platform combined with the high field MRI available at UAMS. We are testing novel radiosensitizers that could be moved into Phase I clinical trials using this model.
-
DNA Damage biomarkers for treatment guidance. We utilize the quantitative immunohistochemistry for DNA repair proteins on pre-treatment biopsy samples to correlate clinical outcomes following radiation. We can discover novel DNA damage biomarkers to personalize treatments for our cancer patients.
Key Publications
Clinical Cancer Research (Journal)
Radiosensitizers are powerful drugs that synergize with radiation therapy doses to destroy cancer cells while preserving healthy tissues. In this publication we investigate miRNA as a novel radiosensitizer.
