Project title: The mechanistic underpinnings of pancreatic NETs

Guillermina Lozano, PhD MD Anderson Cancer Center

Guillermina Lozano, PhD

General Description

Previous NETRF-funded researchers discovered mutations in the genes DAXX and ATRX among tumors from patients with non-functioning pancreatic neuroendocrine tumors. Despite these exciting and promising findings, the precise role of ATRX and DAXX in neuroendocrine tumor development is yet to be understood and treatments exploiting these findings have yet to be developed. Furthermore, researchers do not have the research tools they need to develop potential new therapies for patients exploiting these mutations. In this project, Dr. Lozano will create the mouse models necessary to identify the cellular changes that occur with loss of DAXX and ATRX to determine the impact of DAXX and ATRX mutations on tumor growth. The mouse models that the team creates will both define the importance of the p53 pathway in the maintenance of pancreatic neuroendocrine tumors and be useful to test potential new therapies.

NETRF funds laboratory research to understand the development of neuroendocrine tumors and translational research to explore new concepts in treatment. Research grant descriptions and research updates from NETRF are not intended to serve as medical advice. It can take years for research discoveries to be fully validated and approved for patient care. Always consult your health care providers about your treatment options.
