Researchers identify new plasma membrane sculpting protein

The research group of Professor Pekka Lappalainen at the Institute of Biotechnology, University of Helsinki, has identified a previously unknown mechanism which modifies the structure of plasma membranes in intestinal epithelial cells.

New fluorescent tool can track mysterious workings of cellular RNAs

The ability to tag proteins with a green fluorescent light to watch how they behave inside cells so revolutionized the understanding of protein biology that it earned the scientific teams who developed the technique Nobel Prizes in 2008.

Study shows fall in blood pressure during dialysis for patients increases risk of blood clotting

A sudden drop in blood pressure while undergoing dialysis has long vexed many kidney patients. Side effects associated with this situation over the long term range from stroke to seizure to heart damage to death.

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

Scientists reveal complete three-dimensional atomic structure of an activated GPCR

G protein-coupled receptors (GPCRs) are popular drug targets, accounting for about one-third of approved drugs and many hundreds of drugs currently in development. They act as molecular switches that transduce extracellular signals by activating heterotrimeric G proteins located at the inside of the cell.

Study reveals several compounds that block cancer cell invasion

Metastasis-the spread of cancer from the place where it first started to another place in the body-is the most common reason that cancer treatments fail. To metastasize, some types of cancer cells rely on invadopodia, cellular membrane projections that act like feet, helping them "walk" away from the primary tumor and invade surrounding tissues.

Artificial lung reaches efficiencies akin to the genuine organ

An artificial lung built by Cleveland researchers has reached efficiencies akin to the genuine organ, using air - not pure oxygen as current man-made lungs require - for the source of the essential element.

Promising drug for Duchenne muscular dystrophy

Duchenne muscular dystrophy is a severely debilitating and lethal condition that affects 1 in 3,000. Females and males are affected, though females are rarely affected and are more often carriers. It is caused due to a defective gene that normally codes for the protein dystrophin, which helps provide a protective membrane around muscle fibers. Without this skin, muscle fibers become damaged and eventually die.

MiMedx second quarter revenue increases 85% to $1,929,000

MiMedx Group, Inc., an integrated developer, manufacturer and marketer of patent protected regenerative biomaterials and bioimplants processed from human amniotic membrane, announced today its results for the second quarter and six months ended June 30, 2011.

Researchers characterise protein complex linked to malaria and toxoplasmosis

Maryse Lebrun, Research Director at Inserm, and her fellow researchers at the Laboratoire Dynamique des interactions membranaires normales et pathologiques, have characterised a protein complex that allows the agents that cause malaria and toxoplasmosis to infect host cells.

Strategies toxins use to invade human host cells

Toxins produced by plants and bacteria pose a significant threat to humans, as emphasized by the recent effects of cucumber-borne Shiga toxin in Germany. Now, new research published on July 21st by the Cell Press journal Developmental Cell provides a clearer view of the combination of similar and divergent strategies that different toxins use to invade a human host cell.

Cell biologists identify infection mechanism of adenoviruses

Mucosal epithelia do not have any receptors on the outer membrane for the absorption of viruses like hepatitis C, herpes, the adenovirus or polio, and are thus well-protected against pathogenic germs. However, certain viruses, such as the human immunodeficiency virus HIV, still manage to enter the body via the mucous membrane.

New insights into sleep difficulties among older people

A new study of the brain's master circadian clock - known as the suprachiasmatic nucleus, or SCN - reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

Scientists discover cholesterol moves far slower within and between cells

Neutrons have shown the movement of cholesterol between and within cells takes far longer than previously thought. Findings could impact the treatment of a range of diseases linked to abnormal rates of cholesterol transfer.

Scientists analyze structural changes in calcium channels caused by Timothy-mutation

The human genome encodes 243 voltage-gated ion channels. Mutations in calcium channels can cause severe inherited diseases such as migraine, night blindness, autism spectrum disorders and Timothy syndrome, which leads to severe cardiovascular disorders.

UW scientists determine atomic architecture of sodium channel

Scientists at the University of Washington (UW) in Seattle have determined the atomic architecture of a sodium channel. The achievement opens new possibilities for molecular medicine researchers around the world in designing better drugs for pain, epilepsy, and heart rhythm disturbances.
