UC San Diego professor receives NIDDK grant to study kidney complications related to diabetes

Kumar Sharma, MD, FAHA, professor of medicine at the University of California, San Diego School of Medicine and director of the Center for Renal Translational Medicine, has received a $5.9 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health, to study kidney complications related to type 1 and type 2 diabetes.

Acetyl-L-carnitine likely to improve outcomes and recovery for individuals with SCI

A commonly used supplement is likely to improve outcomes and recovery for individuals who sustain a spinal cord injury (SCI), according to research conducted by University of Kentucky neuroscientists.

Close link between SF3B1 mutation and specific feature of myelodysplastic syndromes

Geneticists have discovered that a gene involved in the modification of ribonucleic acid (RNA) is mutated in a significant proportion of people with a collection of blood cancers called myelodysplastic syndromes.

Researchers identify frequent SF3B1 gene mutation in myelodysplasia

A genomic study of chronic blood cancer - a precursor to leukaemia - has discovered gene mutations that could enable diagnosis using only a blood test, avoiding the need for an invasive and painful bone marrow biopsy.

Regular exercise also increases mitochondrial numbers in brain cells

Researchers have long known that regular exercise increases the number of organelles called mitochondria in muscle cells. Since mitochondria are responsible for generating energy, this numerical boost is thought to underlie many of the positive physical effects of exercise, such as increased strength or endurance. Exercise also has a number of positive mental effects, such as relieving depression and improving memory.

NeuroVive, Selcia sign research collaboration agreement to develop new mitochondrial drugs

UK-based contract research organisation Selcia Limited and Swedish drug development company NeuroVive Pharmaceutical AB have signed a significant research collaboration agreement to develop new medicines and drug compounds targeting mitochondrial physiology and pathophysiology.

Inhibition of Sab protein protects liver from acetaminophen toxicity

New research from the Keck School of Medicine of the University of Southern California (USC) may help prevent damage to the liver caused by drugs like acetaminophen and other stressors.

New surprising discovery on division of mitochondria within cells

A surprising new discovery by the University of Colorado Boulder and the University of California, Davis regarding the division of tiny "power plants" within cells known as mitochondria has implications for better understanding a wide variety of human diseases and conditions due to mitochondrial defects.

Researchers discover new genetic defect that can lead to Leigh syndrome

In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of 3. The problem is that the mitochondria responsible for powering their cells can't keep up with the demand for energy in their developing brains.

Discovery of a key protein’s role in cell clearance could impact future treatments of autoimmune diseases, obesity and atherosclerosis

The healthy human body is extremely efficient at cleaning house. Every day, we purge 100 to 200 billion dead or dying cells – a process called cell clearance, which is fundamental in our ability to maintain a healthy physiological balance and prevent a number of chronic diseases. Professional cleaning cells, called phagocytes, are responsible for ridding the body of dead, or ‘apoptotic,’ cells.

McMaster team demonstrates essential role of AMPK enzyme in exercise

You may think your lack of resolve to get off the couch to exercise is because you're lazy, but McMaster University researchers have discovered it may be you are missing key genes.

New research puts an unexpected twist on how mitochondria divide within cells

New research from the University of California, Davis, and the University of Colorado at Boulder puts an unexpected twist on how mitochondria, the energy-generating structures within cells, divide.

Freiburg researchers receive European Research Council Starting Grants

Marta Artal Sanz, Thomas Brox, Winfried Römer, and Oliver Schilling from the University of Freiburg have been selected for one of the most prestigious European grants for young researchers: The European Research Council (ERC) has awarded them a total of 5.8 million euros in ERC Starting Grants for new projects.

Cell's reserve fighting force shrinks with age: Study

When the body fights oxidative damage, it calls up a reservist enzyme that protects cells - but only if those cells are relatively young, a study has found.

Scientists define specific protein complex that allows cells to remove damaged mitochondria

In a joint research effort with researchers at St. Jude Children's Research Hospital, and with help from scientists at The University of Pennsylvania, The University of Minnesota, and the National Institutes of Health, investigators from the Florida campus of The Scripps Research Institute have defined a specific protein complex that allows cells to rid themselves of damaged mitochondria, which are the energy producing machines of the cell.

Researchers show that Sirt3 enzyme decreases in skeletal muscle of diabetes patients

Researchers at the Joslin Diabetes Center have shown that an enzyme found in the mitochondria of cells is decreased in the skeletal muscle of those with diabetes, a finding that could lead to the development of drugs to boost the activity of this enzyme in an effort to fight the disease.

ATGL produces key signaling molecules essential for regulation of lipid, energy metabolism

Obesity, diabetes, and cardiovascular diseases are daunting modern-day epidemics. In Western Europe more than 50% of the population is overweight and approximately 15 million people die from cardiovascular diseases such as heart attacks and stroke every year. These conditions are often caused by disorders of fat metabolism, resulting in a massive accumulation of fat in various tissues and of cholesterol in the walls of arteries.

Modified Cdk5 enzyme triggers damage to nerve cell connections in human Alzheimer's brains

Alzheimer's disease is characterized by abnormal proteins that stick together in little globs, disrupting cognitive function. These sticky proteins are mostly made up of beta-amyloid peptide. A better understanding of these proteins, how they form, and how they affect brain function will no doubt improve the diagnosis and treatment of Alzheimer's disease.

MAVS prion-like proteins are involved in innate immunity: Discovery

A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report.
