Proteins transform DNA into molecular velcro

Proteins critical for compacting DNA in preparation for cell division actually interact with the double helix to fashion it into a kind of “molecular Velcro,” researchers have discovered.

Drug Tarceva improves survival chance for patients with advanced lung cancer

Roche OSI Pharmaceuticals and Genentech today announced that their investigational drug Tarceva(TM) (erlotinib) achieved a significant 42.5% improvement in median survival compared to placebo in patients with advanced non-small cell lung cancer (NSCLC).

Fibroid tumors lack crucial structural protein

Fibroid tumors-the sometimes painful uterine growths affecting many American women-lack a key protein that plays a role in holding tissues together, according to a study by researchers from the Uniformed Services University of the Health Sciences (USUHS) and the National Institute of Child Health and Human Development of the National Institutes of Health

Genes that allow nerve cells to communicate may have come from bacteria eons ago

Some of the genes that allow nerve cells and some other types of cells to send elaborate chemical messages to each other appear to have been transferred to animals or their immediate ancestors from bacteria eons ago.

New therapy to send cancer-killing drugs directly to tumours

Disguising a molecule to get it past the body's immune system could greatly enhance the success of a groundbreaking new therapy, Cancer Research UK scientists report in the British Journal of Cancer this week.

Novel molecular targeting technologies to deliver gene-silencing therapy

Researchers have combined novel molecular targeting technologies to deliver gene-silencing therapy specifically to tumor cells shielded by a normally impermeable obstacle, the blood brain barrier.

Four critical components of cells' protein-building machine don't do what scientists had long assumed

In the hunt for these details, scientists have focused on four RNA building blocks, or nucleotides, deep within the machine that are identical in every species, from bacteria to humans. Because they sit where the protein chain is actually built, these "universally conserved" nucleotides in the ribosome were thought to help that process.

Researchers identify molecules that underlie nerve fiber degeneration in multiple sclerosis patients

Yale researchers and collaborators have identified molecules that underlie nerve fiber degeneration in patients with secondary progressive multiple sclerosis (MS), a disease that cripples nearly three million people worldwide. The new findings are the first observations in humans of molecules that contribute to degeneration of nerve fibers.

Finding overturns long held ideas about how cells build proteins

Writing in the May 28 issue of Cell, Johns Hopkins researchers report that four critical components of cells' protein-building machine don't do what scientists had long assumed.

New study challenges current thinking about varied response to hepatitis C treatment in different racial groups

Results of a new study published in the current issue of the New England Journal of Medicine show that in patients who have chronic hepatitis C, genotype 1 -- the most common form of the disease and difficult to treat successfully -- non-Hispanic whites achieved one of the highest response rates reported to date, but response rates in African Americans were significantly lower.

Research may lead to elimination of surface-induced thrombus formation

A University of Missouri-Rolla researcher’s investigation into how proteins adhere to surfaces may lead the elimination of surface-induced thrombus formation, a phenomenon known to cause blood clots in artificial arteries, valves and veins.

New technology to measure the sensitivity of nerve fibers that wire up the brain during development

Researchers at Georgetown University have developed a novel technology to precisely measure the sensitivity of nerve fibers that wire up the brain during development. Through use of this technology, they discovered that these fibers, or axons, possess an incredible sensitivity to molecular guidance cues that direct the axon’s route to its desired destination in the brain.
