Study identifies essential mechanism that regulates calcium flow into mitochondria

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Study to examine possible link between mitochondrial DNA and ovarian cancer

Ovarian cancer is a deadly disease. With no overt symptoms and no screening tests to catch it early, ovarian cancer is often detected at stage 3 or later. By then, it can be very aggressive and may have spread beyond the ovaries into other organs. Many women eventually succumb to it; the five-year survival rate for a stage 3 ovarian cancer diagnosis is only 34 percent.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.

Novel method can determine how ready acute myeloid leukemia cells are to die

Researchers at Dana-Farber Cancer Institute have developed a novel method for determining how ready acute myeloid leukemia (AML) cells are to die, a discovery that may help cancer specialists to choose treatments option more effectively for their patients who have AML.

Study shows how CaM kinase II triggers cell death following heart damage

University of Iowa researchers have previously shown that an enzyme called CaM kinase II plays a pivotal role in the death of heart cells following a heart attack or other conditions that damage or stress heart muscle.

RMND1 gene mutations responsible for severe neurodegenerative disorders

Scientists at the Montreal Neurological Institute and Hospital - The Neuro, McGill University working with a team at Oxford University have uncovered the genetic defect underlying a group of rare genetic disorders.

Combination of two neuroprotective therapies shows promise against Alzheimer's

The combination of two neuroprotective therapies, voluntary physical exercise, and the daily intake of melatonin has been shown to have a synergistic effect against brain deterioration in rodents with three different mutations of Alzheimer's disease.

Researchers use nanoparticles to deliver drugs to mitochondria within cells

Nanoparticles have shown great promise in the targeted delivery of drugs to cells, but researchers at the University of Georgia have refined the drug delivery process further by using nanoparticles to deliver drugs to a specific organelle within cells.

New findings establish connection between microRNAs and cellular metabolism

New findings establish a connection between microRNAs and cellular metabolism, suggesting that a drug designed to inhibit these tiny molecules -- once considered to be "junk" DNA -- would have a positive effect against obesity.

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.

XJB-5-131 prevents secondary damage of severe traumatic brain injury

Treatment with an agent that blocks the oxidation of an important component of the mitochondrial membrane prevented the secondary damage of severe traumatic brain injury and preserved function that would otherwise have been impaired, according to a research team from the University of Pittsburgh School of Medicine, Graduate School of Public Health and Department of Chemistry in a report published online today in Nature Neuroscience.

Abnormalities in mitochondrial length promote development of neurodegenerative diseases

Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's.

MitoTarget Project and neurodegenerative diseases: an interview with Rebecca Pruss, Ph.D., CSO of Trophos

The MitoTarget Project was a project funded by the European Commission, under their FP7 programme. It was funding for a call published in 2007.

UCP2 uncoupling protein occurs mainly in cells of the immune system

When uncoupling proteins are active, mitochondria produce heat instead of ATP. This may be useful under certain circumstances, such as when an animal is hibernating. But non-hibernating animals also have them. Particularly poorly understood is the uncoupling protein UCP2. Elena Pohl and colleagues at the University of Veterinary Medicine, Vienna, show that the protein occurs mainly in cells of the immune system.

Study demonstrates how Elesclomol blocks oxidative phosphorylation in melanoma

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease.

New DNA sequencing tests improve ability to analyze genetic disorders

Scientists at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School (UMDNJ-NJMS) have developed new DNA sequencing tests that hold significant promise for decreasing costs associated with diagnosing cancer and hereditary diseases, including cysticfibrosis.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Scripps Florida scientists to identify and develop new therapeutic approaches against cancers

Scientists from the Florida campus of The Scripps Research Institute have been awarded approximately $1.5 million from the National Institutes of Health to identify and develop new therapeutic approaches against a broad spectrum of cancers.

DNA inherited from mother can speed up male ageing

Women outlive men by about five to six years but why? By age 85 there are roughly six women to every four men and by age 100 the ratio is more than two to one.
