Dysfunctional DNA repair pathways

Individuals who inherit two mutant copies of any one of about 12 genes that make the proteins of the Fanconi Anemia (FA) pathway develop FA, which is characterized by increased incidence of cancer and bone marrow failure, among other things.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.

Genes set scene for metastasis - promote spread of breast cancer to the lungs

Biologists at Memorial Sloan-Kettering Cancer Center (MSKCC) have identified a set of genes expressed in human breast cancer cells that work together to remodel the network of blood vessels at the site of the primary tumor.

Massive gene screening points way to more effective chemotherapy

Using a technology that can quickly screen all 20,000-plus human genes for biological activity, scientists have isolated 87 genes that seem to affect how sensitive human cancer cells are to certain chemotherapy drugs.

New research fails to verify gene variations as risk factors for acute coronary syndromes

New research has failed to confirm findings from smaller studies that 85 gene variations are associated with an increased risk for acute coronary syndromes (ACS), which includes heart attack and a type of angina, according to a study in the April 11 issue of JAMA.
