Washington University scientists find an unknown route for cellular fuel delivery

Scientists at Washington University School of Medicine in St. Louis have identified a previously unknown route for cellular fuel delivery, a finding that could shed light on the process of aging and the chronic diseases that often accompany it.

Salk researchers reveal clues into early development of ASD

Autism spectrum disorder is a relatively common developmental disorder of communication and behavior that affects about 1 in 59 children in the US, according to the Centers for Disease Control and Prevention. Despite its prevalence, it is still unclear what causes the disease and what are the best ways to treat it.

Study elucidates how essential amino acid in humans acts as growth signal for cells

A recent study from the Laxman lab elucidates how a small metabolite and amino acid, methionine, acts as a growth signal for cells, by setting into motion a metabolic program for cell proliferation.

Researchers shed new light on the body's largest cell receptor

A giant toadstool that swallow up vitamins and nutrients. This is how the receptor, which e.g. absorbs B12 vitamin, looks. For the first time, researchers have an insight into a biology which has survived millions of years.

Senescent cells in the brain shown to cause obesity-related anxiety

Researchers have shown that obesity increases the level of semi-dormant senescent cells in the brain, which give rise to anxiety-like behaviors.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Scientists cast new light on function of long-mysterious PCSK9 mutation

High levels of low-density lipoproteins, parcels of lipids and protein that carry cholesterol, are a leading risk factor for heart disease. Many cholesterol medications lower LDL, some of them by targeting the protein PCSK9. In the January issue of the Journal of Lipid Research, scientists at the University of California, San Francisco, report on an investigation into why experiments on PCSK9 give different results in a test tube and in liver cells.

Salk scientists show how brain cells filter information in groups

When we perceive the world around us, certain objects appear to be more noticeable than others, depending on what we do. For example, when we view a forest-covered mountain from a distance, the forest looks like a large green carpet. But as we get closer, we start noticing the individual trees, and the forest fades to the background.

New insights on cellular death mechanisms caused by the loss of neuronal cells and astrocytes

The blood circulation to neurons is affected due to Ischemic, hemorrhagic stroke and subarachnoid hemorrhage stimulation the activation of pathophysiological responses i.e. mitochondrial death pathways, protein misfolding, apoptosis, pyroptosis, necrosis, autophagy, mitophagy, ferritinophagy, excitotoxicity, free radicals release, and inflammation.

Sound can affect perception of touch in mice

Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another

How physical activity decreases belly fat in humans

Some of you may have made a New Year's resolution to hit the gym to tackle that annoying belly fat. But have you ever wondered how physical activity produces this desired effect? A signaling molecule called interleukin-6 plays a critical role in this process, researchers report December 27 in the journal Cell Metabolism.

Ancient genomes reveal changes in genetic status of eastern gorillas

The critically endangered Grauer's gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals.

Kanazawa University researchers unravel link between inflammation and cancer

Severe inflammation in tissues is often associated with the occurrence of cancer. The mechanism linking both these conditions is not clearly understood. Furthermore, inflamed and cancerous tissues contain a heterogenous mix of damaged and protective cells.
