UIC researchers pinpoint genes involved in cancer growth

Researchers at UIC College of Medicine identified 57 genes involved in cell proliferation, including some not previously known to play a role in cancer cell growth. The study found that certain fragments inhibited the multiplication of breast cancer cells by shutting down genes necessary for cell growth.
