DOD funds breast cancer research (1-29-01)
The U.S. Department of Defense (DOD) in January awarded $1.8 million for six breast cancer projects at The University of Texas Health Science Center at San Antonio. The projects are in the university’s department of molecular medicine and are conducted at the Institute of Biotechnology, a research facility in the Texas Research Park.
The group at the Institute of Biotechnology has become known worldwide for its research on human breast cancer. "Many of these projects are aimed at understanding the genes that are frequently mutated in breast cancer and the proteins that interact with these gene products," explained P. Renee Yew, Ph.D., one of the DOD grant recipients. She noted that mutations in BRCA1 and BRCA2 (Breast Cancer Susceptibility Genes 1 and 2) are associated with about 80 percent of all cases of familial breast cancer.
"The IBT allows us to collaborate on research targeting human disease, specifically breast cancer," she said. "A disruption of many different cellular processes, such as DNA repair, cell cycle regulation and checkpoint control, can contribute to the cancerous state. Our studies focus on these processes, in addition to less well-characterized processes such as protein degradation, in order to understand how breast cancer develops. We hope that these studies will lead to novel treatments and prevention strategies for breast cancer in the future."
The Department of Defense funds several areas of medical investigation. The Health Science Center is the recipient of other DOD funds for projects including Dr. Gregory Freeman's $14 million congestive heart failure project in the department of medicine/division of cardiology, Dr. Richard Luduena's work in the department of biochemistry, new faculty member Dr. Kristen Vogel's research in the department of cellular and structural biology, and Dr. Gokul Das's work in the department of surgery.
