Tau release from healthy neurons can be regulated by neuronal activity

Researchers from King's College London have discovered that neuronal activity can stimulate tau release from healthy neurons in the absence of cell death.

New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.

Ability to tune gene activity will permit refined research for drug resistance, cancer

Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.

Berkeley Lab researchers resolve EGFR activation mystery

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have provided important new details into the activation of the epidermal growth factor receptor (EGFR), a cell surface protein that has been strongly linked to a large number of cancers and is a major target of cancer therapies.

Tat-beclin 1 shows promise against infections, neurodegenerative disorders and cancer

UT Southwestern Medical Center scientists have synthesized a peptide that shows potential for pharmaceutical development into agents for treating infections, neurodegenerative disorders, and cancer through an ability to induce a cell-recycling process called autophagy.

Investigators discover two new genes associated with severe early-onset disorders of heart rhythm

A team led by Vanderbilt University investigators has discovered two new genes - both coding for the signaling protein calmodulin - associated with severe early-onset disorders of heart rhythm.

Previously poorly investigated signalling pathway crucial for proliferation of prostate cancer cells

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP.

Chemical sensitivity of TRPA1 ion channel may boost melanin production

Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against DNA damage.

Study examines consequences of muscle activity with surprising results

A study in The Journal of General Physiology examines the consequences of muscle activity with surprising results, indicating that the extracellular accumulation of potassium that occurs in working muscles is considerably higher than previously thought.

Biguanide mechanism discovered

Researchers have discovered a novel mechanism by which biguanides exert their glucose-lowering effect, potentially leading to new therapeutic approaches to the treatment of diabetes and insulin resistance.

Seven scientists named 2013 recipients of Damon Runyon-Rachleff Innovation Award

The Damon Runyon Cancer Research Foundation announced that seven scientists with novel approaches to fighting cancer have been named 2013 recipients of the Damon Runyon-Rachleff Innovation Award.

Manipulating transcription factor can change subtype of breast cancer

Australian scientists have shown how a 'transcription factor' causes breast cancer to develop an aggressive subtype that lacks sensitivity to oestrogen and does not respond to anti-oestrogen therapies such as Tamoxifen and aromatase inhibitors.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

Model-independent way to study ion channel gating

Two studies in The Journal of General Physiology (JGP) help pave the way for a "shortcut" model-free approach to studying activation of "polymodal" ion channels-channels that open in response to multiple stimuli. Transmembrane ion channels respond to various physiological stimuli to regulate numerous cellular functions. Different classes of channels respond to different types of stimuli; some channels, for instance, respond to changes in membrane potential whereas others are activated by ligand binding.

Iron oxide nanoparticles could help track transplanted human endothelial cells

A team of researchers from three medical institutions in Guangzhou, China, have found that iron oxide nanoparticles (INOPS) are a useful contrast agent for in vivo magnetic resonance tracking of transplanted human endothelial cells.

Bumetanide could treat children with severe autism or Asperger's syndrome

Although this therapy is not curative, it nevertheless reduced the autistic disorders' severity in three-quarters of the children. The researchers have filed a request for authorisation to perform a multi-centre European clinical trial in order to determine more precisely the population concerned by this therapy.

Oncogene-induced senescence could play a key role in future cancer therapy

Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce senescence, and recent findings have suggested that oncogene-induced senescence (OIS) could play a key role in future cancer therapy.

Alpha arrestins may play a role in cell signaling that is crucial to new drug development

A newly found understanding of receptor signaling may have revealed a better way to design drugs. A study from Nationwide Children's Hospital suggests that a newly identified group of proteins, alpha arrestins, may play a role in cell signaling that is crucial to new drug development.

Immune dysfunction pinpointed in developmental disorder

Children with neurodevelopmental abnormalities resulting from duplication of the methyl-CpG binding protein 2 gene also have impaired T-helper-cell 1 responses, research shows.
