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.

Harvard researcher to receive 2010 Naomi Berrie Award from Columbia University Medical Center

Columbia University Medical Center will present the 2010 Naomi Berrie Award to a Harvard researcher who has made important advances in understanding the molecular basis for links between obesity, diabetes and heart disease. A promising young investigator at Columbia will also be recognized for her novel investigations regarding the basis for disordered lipid metabolism in diabetes.

Cold Spring releases new series of laboratory manuals

Sophisticated techniques that permit the visualization of dynamic processes in cells, tissues, and organ systems at extraordinary levels of resolution have become tremendously valuable in biological research. However, finding the right imaging method and optimizing it for data collection can be a daunting process, even for an established imaging laboratory. To fill this need, a new series of laboratory manuals has been developed by Cold Spring Harbor Laboratory Press. The first volume in this series, Imaging: A Laboratory Manual, has just been released.

New findings on mitochondrial haplogroups associated with successful aging to be presented at ASHG Meeting

Thousands of the world's top scientists and clinicians in the human genetics field will convene to present their latest research findings at the American Society of Human Genetics (ASHG) 60th Annual Meeting, on November 2-6, 2010, in Washington, D.C.

Lactic acid levels in brain linked to aging process

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the CNS.

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.

Research suggests blocking HMGB1 protein can benefit cancer patients

Like some people, cells eat when they are under pressure-but they consume parts of themselves. A multi-function protein helps control this form of cannibalism, according to a study in the September 6 issue of the Journal of Cell Biology.
