Neutrophils dictate whether our immune system will permit or prevent bacterial infections

New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections.

Cancer hijacks normal wound-healing processes

Scientists have known for the last decade that a link exists between wound healing and cancer. For instance, in a 1994 experiment at the Lawrence Berkeley National Laboratory, chickens infected with a cancer virus developed tumors in areas of their body that had undergone wounding or scarring, while no tumors developed in infected areas that had not suffered wounding.

Penn researchers demonstrate that a metabolic enzyme works through the tumor-suppressor protein p53 to control cellular replication

Researchers at the University of Pennsylvania School of Medicine have identified in normal cells that a common metabolic enzyme, which acts as a rheostat of cellular conditions, also controls cell replication.

Nephrogenic Syndrome of Inappropriate Antidiuresis - a new genetic disease

Two infant boys whose bodies were overloaded with excess fluid have led UCSF pediatricians to the discovery of a new genetic disease. In the process, they have discovered a rare type of mutation where different substitutions in a single amino acid cause two different, opposite genetic disorders.

Study reveals new approach to Huntington's disease

Scientific theory holds that Huntington's disease (HD) is caused by a mutant protein that arises within brain cells and kills them, triggering the genetic neurological disorder. Now a new UCLA Neuropsychiatric Institute study reveals the first strong evidence that the mutant protein also elicits toxic interactions from neighboring cells to provoke the fatal brain disorder. The May 5 edition of Neuron reports the findings.

Researchers unravel how nature releases the torque built up in DNA at the molecular level

A Dutch led international team of researchers has unravelled how nature releases the torque built up in DNA at the molecular level. The researchers from Delft University of Technology, the Ecole Normale Supérieure in Paris and the Sloan-Kettering Institute in New York published their findings in the 31 March 2005 issue of Nature. An artistic impression of the enzyme at work is featured on the cover of this issue.

Newly identified fly genes provide clue to tumour growth

Researchers from the Oxford University Department of Human Anatomy and Genetics have found a new class of genes that are critical for cell growth and may be involved in the uncontrolled growth that takes place in cancer. The discovery could provide a key to future tumour therapies.

Researchers develop new method for facile identification of proteins in bacterial cells

Researchers at the Johns Hopkins Bloomberg School of Public Health have developed a new method for identifying specific proteins in whole cell extracts of microorganisms using traditional peptide mass fingerprinting (PMF).

Glucose byproduct prevents brain damage after diabetic coma

A natural, non-toxic byproduct of glucose may prevent brain cell death and cognitive impairment in diabetics following an episode of severely low blood sugar, according to researchers at the San Francisco VA Medical Center (SFVAMC).

Vaccine developed at Rockefeller University boosts natural killer T cells in patients with cancer

A new vaccine designed at The Rockefeller University boosted a type of fast-responding immune system cell called the natural killer T (NKT) cell in patients with advanced cancer. The study surprised researchers by revealing the ability of these NKT cells to spur other, slower-responding immune cells to go to work.

Research suggests potential new strategies for fighting age-related vascular disease

Declining function of cells that help repair the inner lining of blood vessels, known as endothelial progenitor cells, rather than a dwindling supply of the cells, may underlie the increased risk of atherosclerosis and other vascular diseases as people grow older, according to a new study (PDF) in the May 3, 2005, issue of the Journal of the American College of Cardiology.

Mutated gene causes serious heart disease in newborns

The research group of professor Manfred Kilimann at the Department of Cell and Molecular Biology has elucidated the genetic cause of a severe heart disease in newborn children. This result will be published in the June issue of the American Journal of Human Genetics this week.

Two-photon imaging gives real-time video of cells in living tissue

Biologists have a new tool to track and videotape cells moving about inside living tissue.

Study identifies possible marker for efficacy of gefitinib in lung cancer patients

Patients with advanced non–small-cell lung cancer (NSCLC) whose tumor cells contain extra copies of the epidermal growth factor receptor (EGFR) gene may be more likely to respond to the drug gefitinib (Iressa), and this high gene copy number may be an effective predictor of gefitinib efficacy, according to a new study in the May 4 issue of the Journal of the National Cancer Institute.

Researchers have successfully induced adult heart-muscle cells to divide and multiply

In the best documented effort to date, researchers from the Howard Hughes Medical Institute at Children's Hospital Boston and Harvard Medical School have successfully induced adult heart-muscle cells to divide and multiply.

Critical lock and key mechanism found for the assembly of tumor blood vessels

A critical lock and key mechanism that allows the final step in the completion of new blood vessel formation has been identified by a University of California, San Diego (UCSD) School of Medicine team in research that promises to lead to a new way to halt tumor growth by cutting off the tumor blood supply.

Why stem cells divide and develop less vigorously as we age

A comprehensive study from Canada’s Robarts Research Institute has pinpointed two genes that shed significant light on why stem cells divide and develop less vigorously as we age.

Research provides new insight into how individual genes control regeneration

Although they may look small and unassuming, planarian worms are famous in the scientific world for their extraordinary ability to regenerate body parts after injury. Even a small piece cut off a planarian can reorganize and regenerate to form a whole new worm.

Specific genes play key role in the of regulation of human-blood stem cells

This work is the first to validate gene expression analysis in human stem cells with functional experiments. The findings also suggest that changes in the expression of genes associated with universal cell signaling pathways can have a substantial impact on human stem cell behavior.

Cell phone base stations change brain currents and cause unwellness

The radiation of a cell phone base station at a distance of 80 metres causes significant changes of the electrical currents in the brains of testees (measured by electroencefalogram, EEG). All the testees said they felt unwell during the radiation, some of them seriously.
