Redox equilibrium may help identify new diagnostic biomarkers for ageing, neurodegenerative processes

The question of why we age is one of the most fascinating questions for humankind, but nothing close to a satisfactory answer has been found to date.

Atomic level images reveal how neuropeptide hormone neurotensin may activate its receptors

Many hormones and neurotransmitters work by binding to receptors on a cell's exterior surface. This activates receptors causing them to twist, turn and spark chemical reactions inside cells.

Childhood cancer cells produce molecule that affects body's immune system to fight disease

Cancer cells in neuroblastoma contain a molecule that breaks down a key energy source for the body's immune cells, leaving them too physically drained to fight the disease, according to new research published in the journal Cancer Research today (Saturday).

University of Southampton research finds that electric fields alter behaviour of fruit flies

A new piece of research led by the University of Southampton has found that the behaviour of fruit flies, which are commonly used in laboratory experiments, is altered by electric fields.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

Scientists chemically synthesize ECA-derived oligosaccharides relevant for immunotherapy

Immunotherapy using monoclonal antibodies is a promising treatment strategy, and it might now be within reach: American scientists have successfully prepared an oligosaccharide enterobacterial antigen for which a monoclonal antibody has been developed. The study is published in the journal Angewandte Chemie.

Researchers gain new insight into the stages of breast cancer growth

The ability to visualize and characterize the composition of a tumour in detail during its development can provide valuable insights in order to target appropriate therapeutics. The polymer chemist Prof. Dr. Prasad Shastri and the pharmacist Jon Christensen, in collaboration with the biomedical researcher Dr. Daniel Vonwil, from the University of Freiburg have visualized and quantified the growth and composition of breast tumours over time in a living animal.

Taiwanese scientists propose advanced solution that can be applied to thermal cancer therapy

Precise targeting biological molecules, such as cancer cells, for treatment is a challenge, due to their sheer size. Now, Taiwanese scientists have proposed an advanced solution, based on a novel combination of previously used techniques, which can potentially be applied to thermal cancer therapy.

BGI to hold 10th International Conference on Genomics in October

The 10th International Conference on Genomics (ICG-10) will be held by BGI from October 22-25, 2015, in Shenzhen, China.

Study focuses on regulation of neuronal plasticity

A team of scientists has linked changes in the structure of a handful of central brain neurons to understanding how animals adjust to changing seasons. Its findings enhance our understanding of the mechanisms vital to the regulation of our circadian system, or internal clock.

New synthetic gene drives could one day improve human health and the environment

Gene drives are genetic elements - found naturally in the genomes of most of the world's organisms - that increase the chance of the gene they carry being passed on to all offspring, and thus, they can quickly spread through populations. Looking to these natural systems, researchers around the world, including some Wyss Institute scientists, are developing synthetic gene drives that could one day be leveraged by humans to purposefully alter the traits of wild populations of organisms to prevent disease transmission and eradicate invasive species.

Researchers reconstruct ancient virus to improve gene therapy

Researchers at Massachusetts Eye and Ear/Schepens Eye Research Institute have reconstructed an ancient virus that is highly effective at delivering gene therapies to the liver, muscle, and retina. This discovery, published July 30 in Cell Reports, could potentially be used to design gene therapies that are not only safer and more potent than therapies currently available, but may also help a greater number of patients.

Researchers uncover new mechanism that p53 protein uses to trigger cell death

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research Hospital scientists led the study, which appears today in the scientific journal Molecular Cell.

Study reveals how brain work leads to physical fatigue

Do you ever notice how stress and mental frustration can affect your physical abilities? When you are worried about something at work, do you find yourself more exhausted at the end of the day? This phenomenon is a result of the activation of a specific area of the brain when we attempt to participate in both physical and mental tasks simultaneously.

Scientists produce functional liver cells from human embryonic and genetic engineered stem cells

The liver plays a critical role in human metabolism. As the gatekeeper of the digestive track, this massive organ is responsible for drug breakdown and is therefore the first to be injured due to overdose or misuse. Evaluating this drug-induced liver injury is a critical part of pharmaceutical drug discovery and must be carried out on human liver cells. Regretfully, human liver cells, called hepatocytes, are in scarce supply as they can only be isolated from donated organs.

DNA study reveals potential treatments to delay or prevent onset of Huntington's disease

Scientists from Cardiff University believe that a treatment to prevent or delay the symptoms of Huntington’s disease could now be much closer, following a major breakthrough.

Female patients with depression have abnormally high expression levels of glutamate receptor genes

Numerous genes that regulate the activity of a neurotransmitter in the brain have been found to be abundant in brain tissue of depressed females. This could be an underlying cause of the higher incidence of suicide among women, according to research at the University of Illinois at Chicago.

Researchers uncover master regulators that govern the fate of TFH cells

Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear.

New Penn study questions relevance of fish oil-derived SPMs and their anti-inflammatory effects in humans

The importance of a diet rich in fish oils - now a billion dollar food-supplement industry -- has been debated for over half a century. A few large clinical trials have supported the idea that fish oils confer therapeutic benefits to patients with cardiovascular disease. Researchers think that hearts and blood vessels may benefit in part from their anti-inflammatory properties.

IU scientists find evidence that invisible war between microorganisms may affect human health

Health experts have warned for years that the overuse of antibiotics is creating "superbugs" able to resist drugs treating infection.
