Using a novel gene therapy approach that boosts the body?s immune system, a researcher has cured cancer in laboratory mice. In experiments reported in the Dec. 15 issue of Cancer Research, Chung Lee and colleagues at the Feinberg School of Medicine at Northwestern University applied the gene therapy technique to render immune cells insensitive to transforming growth factor beta (TGF-beta), a powerful, naturally occurring substance in the body called an immunosuppressor that enables cancer cells to evade surveillance by the immune system. The approach boosted the mice?s immune system, which virtually eliminated cancerous tumors in the animals' lungs and prostate gland.
