XJB-5-131 compound suppresses symptoms of Huntington's in mice

There's new hope in the fight against Huntington's disease. A group of researchers that includes scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.

Scientists identify mechanism via Top2b enzyme that drives doxorubicin-induced heart damage

Doxorubicin, a 50-year-old chemotherapy drug still in widespread use against a variety of cancers, has long been known to destroy heart tissue, as well as tumors, in some patients.

Male infertility linked to an enzyme complex issue

An enzyme complex present in sperm plasma membranes plays an important role in the overproduction of reactive oxygen species and oxidative stress in sperm with abnormal morphology, researchers have shown.

Vitamin E may prevent cancer in patients with Cowden Syndrome

Cleveland Clinic researchers have discovered that vitamin E may prevent cancer in patients with an under-recognized genetic disorder.

Mitochondrial variations unlikely cause of osteoarthritis

Researchers have been unable to confirm a link between the development of osteoarthritis and maternally inherited mitochondrial DNA variants.

Ageing in neurons follows same rules as in senescing fibroblasts

The ageing process has its roots deep within the cells and molecules that make up our bodies. Experts have previously identified the molecular pathway that react to cell damage and stems the cell's ability to divide, known as cell senescence.

Insight into how tissue stiffness drives cancer

The stiffness of breast tissue is increasingly recognized as an important factor explaining the onset of breast cancer. Stiffening induces molecular changes that promote cancerous behavior in cells. Bioengineering studies have found that breast cancer cells grown on a 3-D gel have enhanced cell replication and decreased organization as rigidity increases.

Mammalian target of rapamycin inhibitors can prevent radiation-induced tissue damage

Radiation therapy is one of the most widely used cancer treatments, but it often damages normal tissue and can lead to debilitating conditions. A class of drugs known as mammalian target of rapamycin (mTOR) inhibitors can prevent radiation-induced tissue damage in mice by protecting normal stem cells that are crucial for tissue repair, according to a preclinical study published by Cell Press in the September issue of the journal Cell Stem Cell.

Reduced NF-κB expression linκed to postradiation oral mucosa vulnerability

The fragility of oral mucosa after radiotherapy for oral squamous cell carcinoma may be due to the inhibition of the DNA transcriptor protein nuclear factor κappa-light-chain-enhancer of activated B cells, show study findings.

TSC and PTEN genes important in controlling blood precursor cells in Drosophila

UCLA stem cell scientists have shown that two common tumor suppressor genes, TSC and PTEN, are vital to regulating the stem cell-like precursor cells that create the blood supply in Drosophila, the common fruit fly.

Nanoparticle may bring great benefits to emergency treatment of brain-injury victims

A nanoparticle developed at Rice University and tested in collaboration with Baylor College of Medicine (BCM) may bring great benefits to the emergency treatment of brain-injury victims, even those with mild injuries.

Microtubule stiffening worsens skeletal muscle degeneration in Duchenne muscular dystrophy

University of Maryland (UM) researchers and collaborators report in the journal Science Signaling that skeletal muscle degeneration in Duchenne muscular dystrophy (DMD) is worsened by stiffening of the microtubule cytoskeleton that provides structure inside muscle cells.

Parkinson’s disease treatment: an interview with Ted Dawson

Parkinson’s disease is a disorder which usually affects people in their 60’s and older. It is caused by the loss of dopamine neurons in the brain leading to rigidity, slowness of movement, tremor, problems with balance and so forth.

Research explains why exercise is beneficial for heart function in type 2 diabetes

A detailed study of heart muscle function in mice has uncovered evidence to explain why exercise is beneficial for heart function in type 2 diabetes. The research team, led by scientists at the Johns Hopkins University School of Medicine, found that greater amounts of fatty acids used by the heart during stressful conditions like exercise can counteract the detrimental effects of excess glucose and improve the diabetic heart's pumping ability in several ways.

Mitochondrial gene regulators involved in Huntington’s disease pathology

Researchers have identified two molecules involved in mitochondrial function that appear to be important in the pathogenesis of Huntington’s disease.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.
