Scientists create novel map of lipid locations in single cell

In real estate, location is everything. The same might be said of lipids - those crucial cellular fats and oils that serve as building blocks for cells and as key energy sources for the body.In a paper published in the September issue of the Journal of Lipid Research, a team of scientists, led by researchers at the University of California, San Diego School of Medicine, has mapped for the first time the actual locations of specific lipids within a single cell.

New squeeze test for screening potential drugs for Alzheimer's

Brain cells exposed to a form of the amyloid beta protein, the molecule linked to Alzheimer's disease, become stiffer and bend less under pressure, researchers at UC Davis have found. The results reveal one mechanism by which the amyloid protein damages the brain, a finding that could lead to new ways to screen drugs for Alzheimer's and similar diseases.

Xcelligence System provides real-time detection of neuronal cell death

Time course analyses of neuronal cell death and its underlying mechanisms require laborious experiments and multiple endpoint assays, often involving labelling with irritating compounds and cell disruption. A recent study used the xCELLigence System of Roche to investigate the response of the neuronal-like cell line HT-22 and cultured primary rat cortical neurons to different cell death stimuli and neuroprotectants.

Study shows increase in IL-6 secretion can reduce Tarceva sensitivity to treat lung tumor cells

One of the most tantalizing developments in anti-cancer therapy over recent years has been the advent of targeted treatments, which have proven highly effective in holding aggressive cancers at bay in certain patients, although typically only for a limited period of time.

New DNA sequencing method can lead to effective individualized medicine

In experiments with potentially broad health care implications, a research team led by a University of Washington physicist has devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively.That could open the door for more effective individualized medicine, for example providing blueprints of genetic predispositions for specific conditions and diseases such as cancer, diabetes or addiction.

New criteria by ACR for early diagnosis, treatment of rheumatoid arthritis

New criteria for rheumatoid arthritis (RA), published in the Annals of Rheumatic Diseases, could prevent thousands of people from developing disabling late stage disease, by redefining how RA should be classified.Rheumatoid arthritis is a progressive autoimmune inflammatory disease, primarily of the joints. If untreated, it leads to damage of bone and cartilage, joint deformities and disability. Around 350,000 people in the UK are living with RA, which affects around three times as many women as men.

ACR announces revised classification criteria for rheumatoid arthritis

The American College of Rheumatology announced the release of revised classification criteria (created in collaboration with the European League Against Rheumatism) for rheumatoid arthritis, which will allow the study of treatments for RA at much earlier stages of the disease—before joint damage occurs—ultimately leading to better patient outcomes.

Alnylam Pharmaceuticals reports significant progress in discovery of novel technologies for systemic delivery of RNAi therapeutics

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, and collaborators from the Massachusetts Institute of Technology (MIT), The University of British Columbia (UBC), AlCana Technologies, Inc., and Tekmira Pharmaceuticals Corporation, presented results from multiple ongoing research efforts regarding the discovery of novel technologies for the systemic delivery of RNAi therapeutics.

New insight into protein transport mechanism can improve chemotherapy treatments

A new study conducted in the department of Biochemistry and Molecular Biology at Tel Aviv University (TAU) elucidates the way in which toxic, yet essential, copper ions enter human cells. As a chemotherapy drug presumably enters the cells in a similar manner, the results of this study pave the way for the development of improved chemotherapeutic drugs. The groundbreaking work was published in the leading American scientific journal PNAS (Proceedings of the National Academy of Sciences).

Scientists identify role of PNPASE in regulating RNA import into mitochondria

Researchers at UCLA's Jonsson Comprehensive Cancer Center and the departments of Chemistry and Biochemistry and Pathology and Laboratory Medicine have uncovered a role for an essential cell protein in shuttling RNA into the mitochondria, the energy-producing "power plant" of the cell. The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria remain poorly understood.

Scientists to develop new antibiotics to tackle infection-causing bacteria

Detailed pictures published today reveal how a new type of experimental antibiotic can kill bacteria that are already resistant to existing treatments. The findings could ultimately help scientists to develop new antibiotics to tackle the bacteria responsible for many hospital and community-acquired infections.

Researchers discover manipulation of microRNA-29a shows potential of novel IBS treatment

A possible cause of irritable bowel syndrome has been traced to a small piece of RNA that blocks a substance protecting the colon membrane, leading to hostile conditions that can produce diarrhea, bloating and chronic abdominal pain.New research shows that this RNA segment sends signals that stop the activity of the gene that produces glutamine, an amino acid. Previous research has linked a shortage of glutamine in the gut with the seepage of toxins and bacteria through the intestinal wall, irritating nerves and creating disease symptoms.

Research findings could lead to new drugs that reduce severity of blood infections leading to sepsis

Scientists have made an important discovery that could lead to new drugs that reduce the severity of blood infections leading to sepsis. Research presented in the August 2010 issue of Journal of Leukocyte Biology shows how interfering with the function of the cell membrane protein called "Programmed Death 1" (PD-1) improves survival in a clinically relevant model of severe infection.
