Natural killer cells battle pediatric leukemia

Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. This disease hinders the development of healthy blood cells while cancer cells proliferate. Currently, children with ALL receive chemotherapy for two to three years, exposing them to significant side effects including changes in normal development and future fertility. As a way to avoid these adverse effects, investigators have been researching how to supercharge the body’s innate cancer-fighting ability — a technique called immunotherapy…

Natural (born) killer cells battle pediatric leukemia

Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. This disease hinders the development of healthy blood cells while cancer cells proliferate. Currently, children with ALL receive chemotherapy for two to three years, exposing them to significant side effects including changes in normal development and future fertility. …

Down syndrome: Behind the scenes of genetics, leukemia

A group of geneticists working in the Faculty of Medicine at the University of Geneva (UNIGE) focused for many years on the genetic characteristics of Down syndrome. They have sequenced the exome, a specific part of our genome, in a cohort of patients affected both by Down Syndrome and Acute Lymphoblastic Leukemia (DS-ALL), a type of cancer relative to the cells of the immune system in the bone marrow. They were able to sketch an outline of the “genetic identity card” of this disease. They found that RAS, an important oncogene in many cancers, is involved in the tumorigenesis of one third of DS-ALL cases…

Way to fight therapy resistant leukemia by blocking DNA repair

Scientists from Cincinnati Children’s Hospital Medical Center report that their experimental combination treatment strategy — using a small molecular inhibitor along with chemotherapy — was particularly effective at stopping a stubborn leukemia called T-cell acute lymphoblastic leukemia, or T-ALL. …
