Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Griffith University and Pfizer in new partnership to unlock nature's cure for infections

In the quest to develop the next generation of anti-infective medicine, Griffith University and Pfizer, the world's largest research-based pharmaceutical company, announced a leading partnership today.

Scientists discover how a well-known protein repairs broken DNA ends

During the life cycle of our cells, a minefield of environmental and biological assaults can lead to double-stranded DNA breaks, the most lethal and dangerous form of DNA damage. Now, in research published online this week in Nature, Rockefeller University scientists reveal that when these breaks occur, a protein called 53BP1 helps repair them by mobilizing their dangly DNA ends - findings that uncover a previously unknown aspect of how double-stranded breaks can get fixed.

Scientists identify a molecule that coordinates the movement of cells

Even cells commute. To get from their birthplace to their work site, they sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix. Now, in research to appear in the October 3 issue of Cell, scientists at Rockefeller University show that a molecule, called ACF7, helps regulate and power this movement from the inside - findings that could have implications for understanding how cancer cells metastasize.

New technology to analyse human cells

A new technology which enables scientists to identify proteins by making a map of the energy flow inside the protein is revealed in Proceedings of the National Academy of Sciences (PNAS) journal.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

No such thing as a 'safe' suntan

Three review papers from leading researchers in the fields of cell biology, dermatology and epidemiology have looked closely at the effects on skin of UV radiation, including that from indoor tanning beds.

Carbon nanotube coating improves electrical stimulation therapy used for Parkinson's, depression, chronic pain

Researchers at UT Southwestern Medical Center have designed a way to improve electrical stimulation of nerves by outfitting electrodes with the latest in chemically engineered fashion: a coating of basic black, formed from carbon nanotubes.

New discovery on growth factor - breakthrough for cancer research

A research team at the Ludwig Institute and Uppsala University has discovered an entirely new signal path for a growth factor that is of crucial importance for the survival and growth of cancer cells.

Why transplanted insulin cells die

New research can enhance survival of islets transplants and improve treatment of type 1 diabetes. Transplantation of insulin-producing cell islets, so-called islets of langerhans is an appealing strategy for treatment of type 1 diabetes. But it turns out that these are short-lived, and the procedure needs to be repeated.

New technique offers hope for stroke sufferers

If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain.

Study reveals how blood flow force protects against atherosclerosis

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the cause of clogged arteries that lead to heart attack and stroke, the authors said. The next set of studies, already underway, seeks to "tweak" the process with the goal of designing a new class of therapies.

Brown fat points to new ways to fight obesity

A surprise discovery -- that calorie-burning brown fat can be produced experimentally from muscle precursor cells in mice -- raises the prospect of new ways to fight obesity and overweight, say scientists from Dana-Farber Cancer Institute.

Scientists discover how mutation in the copper-regulating protein ATP7B causes Wilson disease

Using a combination of computer simulations and cutting-edge lab experiments, physical biochemists at Rice University have discovered how a small genetic mutation -- which is known to cause Wilson disease -- subtly changes the structure of a large, complex protein that the body uses to keep copper from building up to toxic levels.

Researchers uncover attack mechanism of illness-inducing bacterium found in shellfish

An infectious ocean-dwelling bacterium found in oysters and other shellfish kills its host's cells by causing them to burst, providing the invader with a nutrient-rich meal, researchers at UT Southwestern Medical Center have found.

Universal gene signaling mechanism identified by UB molecular researchers

A novel gene signaling mechanism that controls whether a stem cell develops into its destined tissue or fails to differentiate and becomes cancer has been identified by researchers in the multi-laboratory Molecular and Structural Neurobiology and Gene Therapy Program based at the University at Buffalo.

Researchers solve structure of enzyme vital for DNA repair

When dividing cells copy their DNA, mistakes can - and do - occur. To compensate, cells have a built-in system to correct these errors. That correction process isn't thoroughly understood, but researchers are piecing it together bit by bit.

Molecular bridge serves as a tether for a cell's nucleus

A cell's nucleus - home of it its most precious contents - is a delicate envelope that, without support, is barely able to withstand the forces that keep it in place. Now, researchers have discovered a network of molecules in the nuclear membrane that provide the nucleus with rigidity and also facilitate a previously undiscovered form of communication between the cell's nucleus and its cytoplasm.
