Potential new way to suppress tumor growth

Researchers at the University of California, San Diego School of Medicine (home of the Moores Comprehensive Cancer Center), with colleagues at the University of Rochester Medical Center, have identified a new mechanism that appears to suppress tumor growth, opening the possibility of developing a new class of anti-cancer drugs. Writing in this week’s online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), the team reports that a particular form of a signaling protein called STAT5A stabilizes the formation of heterochromatin (a form of chromosomal DNA), which in turn suppresses the ability of cancer cells to issue instructions to multiply and grow.

Among the research institutions NCI funds across the United States, it currently designates 67 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
