Gene that causes aggression in men under stress discovered

Scientists have found that “macho” gene that makes men behave more aggressively than women under stress. They say this one gene could explain why men have a 'fight or flight' response while women are more likely to try and defuse the situation. The study has been published in the journal BioEssays.

Five new genetic mutations linked with Crohn's disease in Ashkenazi Jews

In the largest study of its kind, researchers from Mount Sinai School of Medicine have discovered five new genetic mutations associated with Crohn's disease in Jews of Eastern European descent, also known as Ashkenazi Jews.

Scientists believe that ageing can be programmed in the womb

Ageing is a complex process involving physical, psychological, and environmental factors. Scientists believe that ageing can be programmed in the womb. One example of stress during pregnancy is the administration of glucocorticoids, i. e. synthetic stress hormones to accelerate fetal lung maturation in premature labor to allow breathing after birth. Could exposure to these stress hormones have an effect on health later in life?

Researchers identify mechanism with which cancer cells protect themselves against damage

Although many cancer drugs have already been in use for decades, their mode of action is still unknown. The new research results now challenge a mechanism of action that was previously proposed for a group of drugs and supported with experiments: the Topoisomerase I-inhibitor Camptothecin (Top1 inhibitor for short) and its derivatives used in chemotherapy, Topotecan and Irinotecan.

New APS policy requires reporting of sex and gender in experimental studies

The American Physiology Society (APS) has announced a new policy requiring the reporting of the sex of experimental animals and the sex or gender of humans used in studies submitted for publication in any of the organization's 13 peer-reviewed journals.

Shipment of Fabrazyme commences from Genzyme's FDA-and-EMA-approved Framingham plant

Genzyme, a Sanofi company, today announced that it has begun shipping Fabrazyme (agalsidase beta) produced at its newly approved plant in Framingham, Massachusetts. As previously communicated, patients in the U.S. are now able to return to full dosing in March. In addition, all new patients in the U.S. are eligible to begin Fabrazyme treatment, at full dosing levels.

Review highlights potential strategies for treatment of Down syndrome, AD

Down syndrome (DS) is the most common genetic disorder in live born children arising as a consequence of a chromosomal abnormality. It occurs as a result of having three copies of chromosome 21, instead of the usual two. It causes substantial physical and behavioral abnormalities, including life-long cognitive dysfunction that can range from mild to severe but which further deteriorates as individuals with DS age.

Scientists identify genetic defect responsible for TAR Syndrome

Universitätsmedizin Berlin in collaboration with the Sanger Institute in Cambridge and other cooperation partners in Belgium, the Netherlands and France, were able to identify a genetic defect that is responsible for the development of TAR Syndrome, a congenital malformation of the skeleton and blood.

Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

ACTB and ACTG1 actin genes cause Baraitser-Winter syndrome

Scientists from Seattle Children's Research Institute and the University of Washington, in collaboration with the Genomic Disorders Group Nijmegen in the Netherlands, have identified two new genes that cause Baraitser-Winter syndrome, a rare brain malformation that is characterized by droopy eyelids and intellectual disabilities.

Researchers discover connection between early humans and Neanderthals' genome

A striking discovery in the study of human genetics was the focus of the most-visited press release posted on EurekAlert! in 2011. Researchers found that part of the non-African human X chromosome came from Neanderthals, confirming that they interbred with early human populations.

Scientists demonstrate how immortal flatworm overcomes aging process

Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal.

Aurora-A protein blocks proper functioning of tumor-suppressor p73

A protein abundantly found in treatment-resistant cancers holds an important tumor-suppressor out of the cell nucleus, where it would normally detect DNA damage and force defective cells to kill themselves, a team of scientists reports in the current Cancer Cell.

News briefs from featured presentations at Cardiology 2012

Pediatric cardiology researchers and clinicians from almost 50 centers from across the U.S. and around the world are gathering at the Cardiology 2012 Conference sponsored by The Children's Hospital of Philadelphia on Feb. 22-26 in Orlando, Fla.

Researchers identify elusive gene responsible for TAR syndrome

Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a result, this research is now being transformed into a medical test that allows prenatal diagnosis and genetic counselling in affected families.

Gonadal dysgenesis may also increase risk of gonadal tumors

Pediatric and Developmental Pathology - Gonadal dysgenesis—defective development of the ovaries or testes— may also bring with it an increased risk of gonadal tumors. A recent discovery at the histologic level could help identify cells at risk of conversion into a tumor.

Short telomeres may increase risk of chronic diseases

The ability to anticipate future events allows us to plan and exert control over our lives, but it may also contribute to stress-related increased risk for the diseases of aging, according to a study by UCSF researchers.

DANSR/FORTE assay more effective in diagnosing Edwards and Down syndrome

Using a noninvasive test on maternal blood that deploys a novel biochemical assay and a new algorithm for analysis, scientists can detect, with a high degree of accuracy, the risk that a fetus has the chromosomal abnormalities that cause Down syndrome and a genetic disorder known as Edwards syndrome.

Telomeres - the indicators of aging - are highly susceptible to stress and depression

Stress has numerous detrimental effects on the human body. Many of these effects are acutely felt by the sufferer, but many more go 'unseen', one of which is shortening of telomere length.

Genomic instability allows malignant cells to acquire more deadly characteristics

Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those aps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell.
