Pioneering technique shows promise for new medical diagnostics, targeted drug delivery

Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules--the enzymes.

Lamin nucleoskeleton disordered in Alzheimer's

Brain cell death in Alzheimer's disease is linked to disruption of a skeleton that surrounds the nucleus of the cells, a researcher in the School of Medicine at The University of Texas Health Science Center at San Antonio said.

New gene cut-and-paste methods help correct disease-causing mutation in animal model

For the first time, researchers have treated an animal model of a genetic disorder using a viral vector to deliver genome-editing components in which the disease- causing mutation has been corrected.

CNIO team uses network theory to build and study first epigenetic communication network

One of the big questions for which there is still no clear answer in biology is how, based on the four universal letters that make up DNA, it is possible to generate such different organisms as a fly or a human, or the different organs and tissues they comprise. In recent years, researchers have discovered that the system is much more complicated than was originally thought.

Mindfulness could help children avoid obesity

Mindfulness, described as paying attention on purpose and being in the present moment with acceptance, could be an effective way to help children avoid obesity. New research published in the journal Heliyon suggests that the balance in brain networks in children who are obese is different compared to healthy-weight children, making them more prone to over-eating.

Researchers identify protein that could protect against toxic degeneration of cells in ALS

J. Gavin Daigle, a PhD candidate at the LSU Health New Orleans School of Graduate Studies, is the first author of a paper whose findings reveal another piece of the Amyotrophic Lateral Sclerosis (ALS) puzzle.

UCLA discovery could lead to new therapies for autism

UCLA scientists have discovered that an overlooked region in brain cells houses a motherlode of mutated genes previously tied to autism. Recently published in Neuron, the finding could provide fresh drug targets and lead to new therapies for the disorder, which affects one in 68 children in the United States.

New mechanism of differentiation may offer novel therapeutic approaches to blood malignancies, solid tumors

In humans the differentiation of stem cells into hundreds of specialized cell types is vital. Differentiation drives development from fertilized egg to a newborn, and it underlies the continuous replacement of the 5 billion cells that die every hour in an adult. On the downside, mutations in differentiation pathways of different cell types can be drivers of cancers.

DNA damage may lead to mutation and changes in cell

A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly damaged by things from the outside environment, like sunlight, cigarette smoke and radiation. However, more recently researchers have discovered that sources from within the cell itself can sometimes be even more damaging.

Newly discovered mechanism may help explain why some embryos not useful for fertility treatments

It's the dream of many infertile couples: to have a baby. Tens of thousands of children are born by in vitro fertilization, or IVF, a technique commonly used when nature doesn't take its course. However, embryos obtained when a sperm fertilizes an egg in a test tube often have defects.

New Penn study shows that social behavior in carpenter ants can be reprogrammed

In Florida carpenter ant colonies, distinct worker castes called minors and majors exhibit pronounced differences in social behavior throughout their lives. In a new study published today in Science, a multi-institution team anchored at University of Pennsylvania found that these caste-specific behaviors are not set in stone.

3D maps of spatial organization may help find genes involved in hereditary diseases

It has now been 15 years since scientists celebrated the completion of the human genome. At that point, scientists had determined the entire sequence of the genetic letters making up our DNA.

Eating at the wrong time of day affects learning and memory

An occasional late-night raid on turkey leftovers might be harmless but new research with mice suggests that making a habit of it could alter brain physiology.

Novel drug shows promise in mouse models of human metastatic breast cancer

A doctor treating a patient with a potentially fatal metastatic breast tumor would be very pleased to find, after administering a round of treatment, that the primary tumor had undergone a change in character - from aggressive to static, and no longer shedding cells that can colonize distant organs of the body. Indeed, most patients with breast and other forms of cancer who succumb to the illness do so because of the cancer's unstoppable spread.

New treatment strategy may take pain away

A brain region controlling whether we feel happy or sad, as well as addiction, is remodeled by chronic pain, reports a new Northwestern Medicine study.

New study examines single 'transformer' proteins involved in cancer

A new study led by scientists at The Scripps Research Institute and St. Jude Children's Research Hospital shows how a protein involved in cancer twists and morphs into different structures.

New study improves understanding of metal-based chemotherapy drugs

What is the mechanism of action of metal-based chemotherapy drugs (the most widely used for treating common cancers like testicular or ovarian cancer)? How can we improve their effect and reduce their toxicity? A new study combining experiments and theory has broadened our knowledge of the molecular mechanisms of these active drugs to help experimentalists devising increasingly effective drugs with fewer side effects.

Scientists identify overlooked consequence of spatial separation of cells into nucleus, cytoplasm

Genetically identical cells do not always behave the same way. According to the accepted theory, the reason are random molecular processes - known as random noise. For decades this view has been underpinned by numerous experiments and theoretical models.

UMMS researchers identify new life cycle stage in HIV infection

Researchers at the University of Massachusetts Medical School have identified a new life cycle stage in HIV infection, thanks to a novel technique they developed to take images of intact infected cells.
