Scientists discover linchpin protein that drives mitochondria's calcium machinery

Mitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound.

Scientists identify protein sorting mechanism used by salivary gland

University of Louisville researchers are one step closer to helping millions of people whose salivary glands no longer work because of disease or damage from treatment of diseases.

Pre-implantation genetic diagnosis can avoid mother to child transmission of mtDNA disorders

Dutch researchers have developed a test which predicts which mothers at risk of passing on mitochondrial genetic disease to their children are likely to have a healthy baby.

Molecular mechanism of selected autophagy elucidated

Salmonella is widely prevalent in the animal kingdom. The reason we do not suffer from severe intestinal infections very often is due to our body's defence system, which manages to digest invading bacteria. This is why, generally speaking, a healthy human being will only fall ill if he consumes more than 100.000 salmonella bacteria via a contaminated food source, such as eggs or meat.

Scientists discover protein involved in nerve cell motor-cargo mechanism

With every bodily movement-from the blink of an eye to running a marathon-nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle.

Inorganic nitrate reduces rate of heart dysfunction caused by doxorubicin

Virginia Commonwealth University researchers have found that nutrient supplementation, like the kind that is found in leafy greens, spinach and lettuce, may reduce the damage to the heart caused by a powerful anti-cancer drug.

Researchers find temperature-sensing protein in immune cells

Researchers at The Scripps Research Institute have found a temperature-sensing protein within immune cells that, when tripped, allows calcium to pour in and activate an immune response.

Researchers discover new way to force cancer cells to self-destruct

Researchers at The Wistar Institute have found a new way to force cancer cells to self-destruct. Low doses of one anti-cancer drug currently in development, called Gamitrinib, sensitize tumor cells to a second drug, called TRAIL, also currently in clinical development as part of an anticancer regimen.

Study: Pseudokinases can play a crucial role in pathogen-based disease

Researchers from the University of Pittsburgh and Stanford University discovered that a supposedly inactive protein actually plays a crucial role in the ability of one the world's most prolific pathogens to cause disease, findings that suggest the possible role of similarly errant proteins in other diseases.

New discovery may improve cochlear implants for deafness

University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain.

Malaria drug shrinks, slows resistant pancreatic tumors

Dana-Farber Cancer Institute scientists report they have shrunk or slowed the growth of notoriously resistant pancreatic tumors in mice, using a drug routinely prescribed for malaria and rheumatoid arthritis.

Researchers discover new gene for Sensenbrenner syndrome

Dutch researchers of the Radboud University Medical Center in Nijmegen found a new gene for Sensenbrenner syndrome (Journal of Medical Genetics, 2011 Mar 4). The mutation adds support to the hypothesis that defects in ciliar transport are the cause of the disease. Project leader Dr. Heleen H. Arts is supported by a Kolff Junior Postdoc Grant of the Dutch Kidney Foundation.

Study: Roundworm protein can suppress inflammation in patients with sepsis

Research by the University of Liverpool has found that systemic inflammation caused by sepsis can be suppressed by a protein which occurs naturally in a type of roundworm.

New computer-controlled system to create cell assembly line

Borrowing a page from modern manufacturing, scientists from the Florida campus of The Scripps Research Institute have built a microscopic assembly line that mass produces synthetic cell-like compartments.

New personalized therapy fools cancer cells into killing themselves

A Wayne State University School of Medicine physician-researcher has developed a personalized therapy to treat a wide range of cancers. The treatment is based on a naturally occurring human enzyme that has been genetically modified to fool cancer cells into killing themselves.

Some fat is essential for body function

It's common knowledge that too much cholesterol and other fats can lead to disease, and that a healthy diet involves watching how much fatty food we eat. However, our bodies need a certain amount of fat to function—and we can't make it from scratch.

Malaria parasite caught in action on film for the first time

Australian researchers have managed to take pictures of microscopic malaria parasite as it invades a human red blood cell. This will provide a deeper understanding of the parasite’s behaviour and may help fight it. Up to 10% of the world’s population contract malaria every year and a million people, mostly pregnant women and children, die as a result of the parasite transmitted by infected mosquitoes.

Fungus may provide clue about human response to changes in circadian rhythm

Humans are not the only species ruled by a circadian rhythm. Even simple organisms like moulds are governed by an inner clock. Studying red bread mould may teach us how our own internal clock works. This is exactly what the Centre for Organelle Research at the University of Stavanger, Norway is doing.

Sequestering GSK3 enzyme leads to stabilization of proteins in cells

The cell signaling pathway known as Wnt, commonly activated in cancers, causes internal membranes within a healthy cell to imprison an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and affecting the stability of many proteins within the cell, researchers at UCLA's Jonsson Comprehensive Cancer Center have found.

DFG announces establishment of eleven new Collaborative Research Centres

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven new Collaborative Research Centres (CRC) as of 1 January 2011. This decision was made recently by the responsible Grants Committee at its autumn meeting in Bonn. The new CRCs will receive a total of - 94.4 million (including a 20 percent programme allowance for indirect project costs) for an initial funding period of four years.
