Gene Loss Can Cause Leukemia, Flanders Institute for Biotechnology Researchers Find

ScienceDaily (June 8, 2010) — Researchers from VIB and K.U.Leuven, both in Flanders, Belgium, have discovered a new factor in the development of acute lymphoblastic leukemia, a disease that mainly affects children. In the cells of the patients, the specific gene PTPN2 ceases to function, causing the cancer cells to survive longer and grow faster. The study provides genetic and functional evidence for a tumor suppressor role of PTPN2.
