Study: New anti-cancer agents halt cancer metastasis

ke microscopic inchworms, cancer cells slink away from tumors to travel and settle elsewhere in the body. Now, researchers at Weill Cornell Medical College report in today's online edition of the journal Nature that new anti-cancer agents break down the loping gait these cells use to migrate, stopping them in their tracks.

New method may shed light on the mechanism behind folding and misfolding of proteins

Researchers at the Department of Chemistry at the Technische Universit-t M-nchen (TUM) have developed a method that allows the observation of local movements in proteins on a time scale of nanoseconds to microseconds.

New findings shed light on how genetic damage to muscle cell proteins can lead to nemaline myopathy

New findings that shed light on how genetic damage to muscle cell proteins can lead to the development of the rare muscle-wasting disease, nemaline myopathy, are reported today (15 March) in the Biochemical Journal.

Bionanomotors can be used some day to move and manipulate molecules at nanoscale

A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single molecules-a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales.

Researchers identify a key piece in the ageing process

Understanding how aged and damaged mother cells manage to form new and undamaged daughter cells is one of the toughest riddles of ageing, but scientists now know how yeast cells do it. In a groundbreaking study researchers from the University of Gothenburg, Sweden, show how the daughter cell uses a mechanical "conveyor belt" to dump damaged proteins in the mother cell.

New study indicates viruses employ a novel mechanism to spread more quickly than thought possible

New video footage of a virus infecting cells is challenging what researchers have long believed about how viruses spread, suggesting that scientists may be able to create new drugs to tackle some viruses.

Motility mechanism of malaria pathogens explained

How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa?

Discovery suggests how toxin-filtering cells go awry

Researchers from Children's Hospital Boston and Brigham and Women's Hospital have identified an important genetic cause of a devastating kidney disease that is the second leading cause of kidney failure in children, according to The NephCure Foundation.

New technology sheds light on intracellular transport

Using new technology developed in his University of Oregon lab, chemist Andrew H. Marcus and his doctoral student Eric N. Senning have captured what they describe as well-orchestrated, actin-driven, mitochondrial movement within a single cell.

Energid Technologies to develop robotic device for endotracheal intubation

The US Army, through the Telemedicine and Advanced Technology Research Center (TATRC), has awarded Energid Technologies a contract to develop a robotic approach to airway management.

Discovery of cell fibrous structure may provide clues to diagnose and treat medical disorders

Researchers from the Johns Hopkins Engineering in Oncology Center have shown that in healthy cells, a bundled "cap" of thread-like fibers holds the cell's nucleus, its genetic storehouse, in its proper place.

Portuguese scientists identify a molecular mechanism that can lead to metastases in breast cancers

Portuguese scientists identified a molecular mechanism that can lead to metastases (spread of the cancer from the original site to other remote parts of the body) in breast cancers. Abnormally high levels of P-cadherin - an adhesion molecule that enables cells to bind together - occur in about a third of all breast cancers and are associated with poor prognosis.

Comprehensive investigation employing FRET to study amino acid transporter GAT1 reported

In the December 2009 issue of the Journal of General Physiology (www.jgp.org), Moss et al. report a comprehensive investigation employing F-rster resonance energy transfer (FRET) to study the {gamma}-amino acid (GABA) transporter GAT1, a member of the family that includes transporters for neurotransmitters dopamine (DAT), serotonin (SERT), norepinephrine (NET) and glycine (GlyT).

Protein mutation can cause a new form of heart failure

Over the course of a lifetime, the heart pumps some 250 million liters of blood through the body. In the order to do this, the muscle fibers of the heart have to be extremely durable. The research group headed by Dr. Wolfgang Rottbauer, vice chair of the Department of Medicine III at Heidelberg University Hospital (Chairman: Prof. Dr. H. A. Katus), has discovered a protein that is responsible for the stability of the smallest muscular unit, the sarcomere.

The Australian Institute of Policy and Science awards Dr Jake Baum for malaria research

Research aimed at developing drugs that stop malaria parasites from spreading throughout the body has seen Dr Jake Baum, from the Walter and Eliza Hall Institute, named a Young Tall Poppy by the Australian Institute of Policy and Science.

DISC1 linked to proper development and migration of neurons in the brain

Scientists now have a better understanding of a perplexing gene that is associated with susceptibility for a wide spectrum of severely debilitating mental illnesses. Two independent research studies published by Cell Press in the September 24th issue of the journal Neuron provide fascinating insight into the molecular mechanisms that link disrupted-in-schizophrenia 1 (DISC1) with the proper development and migration of neurons in the hippocampus, a brain area involved in learning and memory and associated with the pathology of schizophrenia.

Titanium dioxide nanoparticles catalyze brain tumor death

Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago Medical Center's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to antibodies.

Researchers discover HIV Nef protein's role in cell mobility inhibition

In order to be able to ward off disease pathogens, immune cells must be mobile and be able to establish contact with each other. The working group around Professor Dr. Oliver Fackler in the Virology Department of the Hygiene Institute of the Heidelberg University Hospital has discovered a mechanism in an animal model revealing how HIV, the AIDS pathogen, cripples immune cells: Cell mobility is inhibited by the HIV Nef protein.

Disruption of the spectrin-actin network leads to lens cell in the eye to lose their shape: Study

A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14).

Scientists to get funding from The European Research Council

The European Research Council (ERC) expects to fund some 240 top researchers in its second prestigious ERC Starting Grant competition. This new wave of grantees follows the 299 researchers who received grants in the first Starting Grant competition in 2007.
