Protein that promotes 'cell-suicide' could revolutionize eye cancer treatment

Tue, 06/12/2016 - 4:01pm
New research has identified the role of a specific protein in the human body that can help prevent the survival and spread of eye cancer, by initiating cancer 'cell-suicide.'

The balancing act: An enzyme that links endocytosis to membrane recycling

Tue, 06/12/2016 - 4:01pm
All cells have surface membranes and maintaining the surface area of this membrane is critical to the normal functioning of cells. The surface membranes of cells lining our lungs, guts and the light-sensing cells of our eyes undergo constant recycling to operate effectively. Using the light-sensitive membranes in fruit fly eyes as a model system, have recently identified an enzyme named Phospholipase D or PLD -- that is essential for recycling of membranes for normal sight.

Speed data for the brain's navigation system

Tue, 06/12/2016 - 4:00pm
In order to guide us accurately through space, the brain needs a 'sense' of the speed of our movement. But how do such stimuli actually reach the brain? Researchers have now identified a signal pathway in mice that feeds speed information directly into the brain's navigation system.

Resilience: A small, quiet word with huge alcohol use disorder implications

Tue, 06/12/2016 - 3:35pm
Certain personality traits – such as disinhibition (a lack of restraint) and impulsivity – increase the chances of developing alcohol use disorders (AUDs), new research shows.

Pathway linked to slower aging also fuels brain cancer

Tue, 06/12/2016 - 3:35pm
A metabolic pathway linked to slower aging is overactive in a deadly form of brain cancer, according to researchers. Their findings suggest that tweaking the pathway to treat cancer may affect other biological processes, such as aging.

Combination immune therapy shows promise against Hodgkin lymphoma

Tue, 06/12/2016 - 3:34pm
The combination of two new drugs that harness the body’s immune system is safe and effective, destroying most cancer cells in 64 percent of patients with recurrent Hodgkin lymphoma, according to the results of an early-phase study.

Honey bee teenagers speed up the aging process of their elders

Tue, 06/12/2016 - 2:46pm
In honey bee colonies, a single queen is laying eggs from which thousands of worker bees are born. At a young age, workers care for the brood, then build and defend the nest and eventually, towards the end of their lives, leave the safety of the nest to forage for food. This major step in their lives is speeding up ageing because searching the environment for food exposes these foragers to a wide range of stressors, such as pathogens, predators and adverse weather conditions.

Scientists show NLRP2 protein's role in maintaining fertility later in life

Tue, 06/12/2016 - 2:45pm
Researchers have demonstrated in animal models that a protein called NLRP2 plays an important role in early embryogenesis, the process of cell division in fertilized eggs that occurs before they implant into the lining of the uterus. In addition, the protein was shown to become more important with increasing maternal age, as blocking NLRP2 in eggs prevented them from developing in blastocysts. As a similar protein exists in humans, these insights may lead to greater understanding of reproductive disorders and novel paths to treatment, report investigators.

How tequila could be key in our battle against climate change

Tue, 06/12/2016 - 2:42pm
Agave – the cactus-like plant which forms the base ingredient of tequila – has a nocturnal ‘body clock’ which allows it to ‘breathe’ at night and withstand the driest of conditions, new research has shown.

What happens in the cell nucleus after fertilization?

Tue, 06/12/2016 - 2:42pm
A team of scientists shows changes in the immediate environment of DNA after the ovum and sperm fuse to form the zygote. The results suggest why all conceivable somatic cells can develop from the germ cells.

Immunotherapy shows promise in preventing leukemia relapse

Tue, 06/12/2016 - 12:18am
Promising results have been announced from an early trial in which patients with high-risk acute myeloid leukemia received genetically engineered immune cells. Of the 12 AML patients who received this experimental T-cell therapy after a transplant put their disease in remission, all are still in remission after a median follow-up of more than two years.

Protecting babies from eczema with low-cost Vaseline

Mon, 05/12/2016 - 9:58pm
Seven common moisturizers would be cost effective in preventing eczema in high-risk newborns, research shows. By using the cheapest moisturizer in the study (petroleum jelly), the cost benefit for prophylactic moisturization was only $353 per quality-adjusted life year – a generic measure of disease burden that assesses the monetary value of medical interventions in one’s life.
