Research examines link between metabolic syndrome and cognitive disorders

No effective treatments are currently available for the prevention or cure of Alzheimer's disease (AD), the most frequent form of dementia in the elderly. The most recognized risk factors, advancing age and having the apolipoprotein E Ɛ4 gene, cannot be modified or treated. Increasingly, scientists are looking toward other risk factors to identify preventive and therapeutic strategies.

High doses of tiny milk vitamin produces numerous health benefits in mice

A novel form of vitamin B3 found in milk in small quantities produces remarkable health benefits in mice when high doses are administered, according to a new study conducted by researchers at Weill Cornell Medical College and the Polytechnic School in Lausanne, Switzerland.

New approach can design antibiotics that kill even 'superbugs'

The world needs new antibiotics to overcome the ever increasing resistance of disease-causing bacteria - but it doesn't need the side effect that comes with some of the most powerful ones now available: hearing loss. Today, researchers report they have developed a new approach to designing antibiotics that kill even "superbugs" but spare the delicate sensory cells of the inner ear.

Nrf2-KEAP1 protein may play a role in diabetic retinopathy

A Wayne State University researcher believes a protein that fails to reach the nucleus of retinal cells may play a role in causing eye disease in people with diabetes.

Investigational diabetes drug appears to improve insulin sensitivity without side effects

Drugs for type 2 diabetes can contribute to weight gain, bone fractures and cardiovascular problems, but in mice, an investigational drug appears to improve insulin sensitivity without those troublesome side effects, researchers at Washington University School of Medicine in St. Louis have shown.

Researchers devise strategy to directly activate natural ‘death’ protein

Researchers at Dana-Farber/Children's Hospital Cancer Center have devised a strategy to directly activate a natural "death" protein, triggering the self-destruction of cells. They say the development could represent a new paradigm for designing cancer drugs.

Scientists develop synthetic peptide that overcomes cancer cells’ survival defenses

Scientists at the Dana-Farber/Children's Hospital Cancer Center have developed an anti-cancer peptide that overcomes the stubborn resistance to chemotherapy and radiation often encountered in certain blood cancers when the disease recurs following initial treatment.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

Researchers identify two gene mutations that cause neuromuscular disorder

Research into how carbohydrates are converted into energy has led to a surprising discovery with implications for the treatment of a perplexing and potentially fatal neuromuscular disorder and possibly even cancer and heart disease.

Placental stem cells with key therapeutic properties can be harvested from chorion

Scientists at Children's Hospital Oakland Research Institute (CHORI) led by Vladimir Serikov, MD, PhD, and Frans Kuypers, PhD, report in the current Epub issue of Stem Cells Translational Medicine that placental stem cells with important therapeutic properties can be harvested in large quantities from the fetal side of human term placentas.

Administering vitamin K2 could possibly help patients with Parkinson's

Neuroscientist Patrik Verstreken, associated with VIB and KU Leuven, succeeded in undoing the effect of one of the genetic defects that leads to Parkinson's using vitamin K2. His discovery gives hope to Parkinson's patients.

Glial cells pass on metabolites to neurons

Around 100 billion neurons in the human brain enable us to think, feel and act. They transmit electrical impulses to remote parts of the brain and body via long nerve fibres known as axons. This communication requires enormous amounts of energy, which the neurons are thought to generate from sugar. Axons are closely associated with glial cells which, on the one hand, surround them with an electrically insulating myelin sheath and, on the other hand support their long-term function.

Study describes new family of six genes that control mitochondrial transport in neurons

A team headed by Eduardo Soriano at the Institute for Research in Biomedicine (IRB Barcelona) has published a study in Nature Communications describing a new family of six genes whose function regulates the movement and position of mitochondria in neurons.

Protein vital for cell survival and immune balance has another form with different function

Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work.

Body’s own DNA can cause inflammation in the heart

DNA from the heart's own cells plays a role in heart failure by mistakenly activating the body's immune system, according to a study by British and Japanese researchers, co-funded by the British Heart Foundation.

Novel technological treatment for Leber Hereditary Optic Neuropathy

A research team, led by John Guy, M.D., professor of ophthalmology at Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine, has pioneered a novel technological treatment for Leber Hereditary Optic Neuropathy (LHON), an inherited genetic defect that causes rapid, permanent, and bilateral loss of vision in people of all ages, but primarily males ages 20-40.

Avocado oil protects against free radicals in mitochondria

Atmospheric oxygen facilitated the evolution and complexity of terrestrial organisms, including human beings, because it allowed nutrients to be used more efficiently by those organisms, which in turn were able to generate more energy. However, as we find out more about how oxygen molecules work inside the body, more attention is being paid to their not-so-good effects, and researchers are seeking ways to thwart them.

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes

Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.
