Does The Impact Of Psychological Trauma Cross Generations?
09/09/2010 04:00 AM
|
In groups with high rates of posttraumatic stress disorder (PTSD), such as the survivors of the Nazi Death Camps, the adjustment problems of their children, the so-called "Second Generation", have received attention by researchers. Studies suggested that some symptoms or personality traits associated with PTSD may be more common in the Second Generation than the general population...

Insulin Implicated In Cell Survival, Cell Metabolism And Stress Response
09/09/2010 03:00 AM
|
Researchers at the Buck Institute for Age Research have discovered a novel way in which insulin affects cell metabolism and cell survival. Surprisingly the insulin signaling pathway, which is involved in aging, diabetes and stress response, is active at a deeper level of cell activity than scientists expected. The study appears in the September 8th issue of Cell Metabolism...

Researchers Uncover Activation Signal For Aurora-A Oncogene
09/08/2010 04:00 AM
|
Aurora-A kinase (AurA) is an enzyme that is hyperactive in many cancers and drives tumor cell proliferation. Several AurA inhibitors are currently being tested in clinical trials to see if they slow tumor growth. Now, researchers in the Developmental Therapeutics Program at Fox Chase Cancer Center have identified an activation signal for AurA...

The Role Of CEP290 In Maintaining Ciliary Function Defined By Researchers
09/07/2010 05:00 AM
|
A new study in the September 6 issue of the Journal of Cell Biology helps define the role of an important ciliary protein, CEP290. The results could be applied toward targeted gene therapy in cilia-related diseases. Mutations in human CEP290 cause cilia-related disorders that range in severity from isolated blindness to perinatal death...

Blocking HMGB1 May Benefit Cancer Patients
09/07/2010 04:00 AM

Like some people, cells eat when they are under pressure - but they consume parts of themselves. A multi-function protein helps control this form of cannibalism, according to a study in the September 6 issue of the Journal of Cell Biology. Cells often respond to hunger or stress by digesting some of their contents...

Stress Resilience Returns With Feeling For Rhythm
09/07/2010 03:00 AM
|
If your body releases cortisol with fixed regularity then you can cope with stress better, says NWO-funded researcher Angela Sarabdjitsingh. She investigated the rhythm of corticosterone production in rats. This rat hormone is comparable to the human stress hormone cortisol. Rats deal considerably less well with stress if the pattern of corticosterone release changes...

Backstabbing Bacteria, A New Treatment For Infection?
09/06/2010 05:00 AM
|
Selfish bacterial cells that act in their own interests and do not cooperate with their infection-causing colleagues can actually reduce the severity of infection. The selfish behaviour of these uncooperative bacteria could be exploited to treat antibiotic-resistant infections, according to research being presented at the Society for General Microbiology's autumn meeting today...
