Researchers report how Alzheimer's protein deposits disrupt signalling between nerve cells

How abnormal protein deposits in the brains of Alzheimer's patients disrupt the signalling between nerve cells has now been reported by researchers in Bochum and Munich, led by Dr. Thorsten M-ller from the Medizinisches Proteom-Center of the Ruhr-Universit-t, in the journal Molecular and Cellular Proteomics. They varied the amount of APP protein and related proteins associated with Alzheimer's disease in cell cultures, and then analysed how this manipulation affected other proteins in the cell.

New birth-control strategy for mosquitoes can combat malaria

Using information about the unique mating practices of the male malaria mosquito ― which, unlike any other insect, inserts a plug to seal its sperm inside the female ― scientists are zeroing in on a birth-control drug for Anopheles mosquitoes, deadly carriers of the disease that threatens 3 billion people, has infected more than 215 million and kills 655,000 annually.

Researchers identify molecular and protein signatures that predict HCV virus-induced liver injury

Researchers have discovered molecular and protein signatures that predict rapid onset of liver damage in hepatitis C patients following a liver transplant. The markers appeared soon after transplant and well before clinical evidence of liver damage.

New 3-D view of the body's response to infection

A new 3-D view of the body's response to infection - and the ability to identify proteins involved in the response - could point to novel biomarkers and therapeutic agents for infectious diseases.

Neural precursor cells suppress aggressive tumors

Neural precursor cells (NPC) in the young brain suppress certain brain tumors such as high-grade gliomas, especially glioblastoma (GBM), which are among the most common and most aggressive tumors.

Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

WCMC receives NHLBI grant to study smoking-induced COPD

Researchers at Weill Cornell Medical College were awarded a $6.5 million grant from the National Heart, Lung, and Blood Institute for a five-year investigation into metabolic changes occurring within airway epithelial cells in the lungs of chronic obstructive pulmonary disease (COPD) patients caused by cigarette smoking. In addition, researchers aim to identify which cigarette smokers are at highest risk of developing COPD as well as novel biomarkers to assist in the development of new therapeutic treatments for the disease.

Body rids itself of excess copper through urine: New study

Scientists have long known that the body rids itself of excess copper and various other minerals by collecting them in the liver and excreting them through the liver's bile. However, a new study led by Johns Hopkins researchers and published June 22 in PLoS One suggests that when this route is impaired there's another exit route just for copper: A molecule sequesters only that mineral and routes it from the body through urine.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

Two new tests tend to overestimate vitamin D deficiency

Blood tests to measure vitamin D deficiency are among the most frequently ordered tests in medicine. But a Loyola University Chicago Stritch School of Medicine study of two new vitamin D tests found the kits are inaccurate in many cases. Earle W. Holmes, PhD, presented findings at ENDO 2012, the 94th Annual Meeting and Expo in Houston.
