Genetic tendency toward suicide linked to genome on chromosome 2

A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide.

Four genes identified that increase risk of developing type 2 diabetes

This form of diabetes is the most common worldwide and affects nearly 2 million Canadians. In recent years, the prevalence of Type 2 diabetes has increased rapidly. This genetic discovery may help stem this rise.

Enzyme important in fetal heart-cell failure - findings provide new targets for treatment

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.

Largest collection of autism DNA

Preliminary findings from the largest genome scan ever completed in the history of autism research are being published in Nature Genetics. University of Pittsburgh researchers with a consortium of scientists from across the world contributed to this landmark research endeavor through the Autism Genome Project.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Survey finds perceived risk of recurrence is low in African American breast cancer survivors

A unique survey of African American breast cancer survivors at heightened risk for hereditary breast cancer has found the majority do not believe they have an increased chance of developing the cancer again.

Shortening chromosomes cause for earlier cancer onset in families with Li-Fraumeni syndrome

In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.

Twin study on the increased cardiometabolic risk in obesity

A unique monozygotic twin study by researchers from the Finnish Twin Cohort, Helsinki University Central Hospital, and VTT Technical Research Centre of Finland found that obesity, already in its early stages and independent of genetic influences, is associated with deleterious alterations in the lipid metabolism known to facilitate atherogenesis, inflammation and insulin resistance.

Mechanism driving iron overload in thalassemia identified

Led by researchers at Weill Cornell Medical College in New York City, an international group of scientists has pinpointed a specific genetic relationship as the cause of dangerous iron overload in persons with a form of the inherited blood disease, beta-thalassemia.
