Pair of cancer genes found to drive both cell migration and division

...known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell. The researchers discovered that the two genes are required for a dividing cell's halves to separate, raising the possibility that interfering with them could be help...

New understanding of cell movement may yield ways to brake cancer's spread

...eir vital connections, embryonic cells move to the proper places to form organs, immune cells zero in to destroy pathogenic organisms, and cancer cells metastasize, spreading deadly disease through the body. Scientists studying these migrations didn't know how cells determined where to go. Until now. A Bur...

The first impact factor for PLoS Biology ?13.9

...buted, and reused, without restriction (aside from proper citation of the authors), and now we know that the journal has also been cited time and time again. PLoS Biology was launched to provide biologists who support open access a high profile journal for their best research papers and to demonstrate that...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

...), was found to play a key regulatory role for the proper functional integration of these new neurons in the...y. PK2 allows these new neurons to settle into the proper areas of the olfactory bulb, thus permitting these neurons to function normally. "Our findings iden...

Researchers seek to discover what really happens when a virus enters the body

...ges must be taken quickly, then reassembled in the proper matrix. The "montage" artifact arises from the microscope's uneven illumination, which is brighter in the center and dissipates nearer the edges of the dish for each sub-image. To compensate for this artifact or noise, Bell's lab has developed "a m...

Scientists focus on 'dwarf eye'

...the retina is the right distance from the lens for proper focus of images on the retina, a largely unknown mechanism that uses visual experience causes the eye to stop growing. Due to natural genetic mutations, some eyes continue to grow beyond this point, causing nearsightedness. Other mutations cause the...

Beauty queens urge girls not to sacrifice their bones

...ber from Lebanon who spoke about the importance of proper diet (including adequate calcium and vitamin D), and sufficient exercise, in building bone strength and mass. He also pointed out that certain lifestyle activities, such as eating disorders, smoking and excessive alcohol consumption, can be detriment...

MicroRNA tweaks protein that controls early heart development

...2 protein at precisely the right time to allow the proper development of heart muscle. "We think that Hand2 is necessary in the early stages of embryonic development to allow proliferation and expansion of a pool of muscle progenitor cells that can eventually develop into the heart," said Dr. Deepak Srivas...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...arly detection system. It can: * Increase the proper use of antiviral medicines. Although such medicines have been developed for some respiratory viruses, they are not used often as therapy because they are only effective if given early in the course of infection. By the time current tests identify the...

Hormones and growth: The control of body size and developmental growth rate in fruit flies

... developing flies sense that they have reached the proper size to initiate a new phase of development. Their new findings show that the prothoracic gland'the organ that releases ecdysone'itself acts as a size-sensing tissue. The researchers found that by manipulating the growth of specific cells within the ...

UIC researchers show protein routes messages in nerve cells

... work simultaneously. Which goes where to send the proper message? Research reported in the July 20 issue of the Journal of Neuroscience (released online July 13) by a team led by David Featherstone, a University of Illinois at Chicago assistant professor of biology, provides some important preliminary ans...

Researchers create functioning artificial proteins using nature's rules

...mation contained within that sequence produces the proper structure. All proteins are made up of 20 specific amino acids. Even for a small protein made up of 100 amino acids, the number of possible combinations of amino acids is staggering, many times more than the number of atoms in the known universe. ...

Researchers find molecule that inhibits regrowth of spinal nerve cells

...that helps the body's motor nerve cells grow along proper paths during embryonic development also plays a major role in inhibiting spinal-cord neurons from regenerating after injury, researchers at UT Southwestern Medical Center have found. In cultured cells, the researchers found that a component of myelin...

Gradient guides nerve growth down spinal cord

...al and thoracic spinal cord until they reach their proper position, usually after seven to ten days. From previous studies, Zou and colleagues knew that a gradient of various Wnt proteins, including Wnt4, formed along the spinal cord around the time of birth. Here they show that two other proteins, Wnt1 an...

'Cookbook recipes' would cure disease with nontoxic DNA delivery systems

... disorders, for example, but delivering DNA to the proper location and getting the right amount of DNA expression without killing innocent cells has become the Achilles' heel in DNA delivery. Positively charged (cationic) synthetic molecules will readily bond to negatively charged DNA molecules and have be...

NYU biologists map out early stages of embryo formation

"This may also be the case for human embryogenesis. The diagrams linking all these genes reveal discret...

Researchers Discover Gene That Determines Asthma Susceptibility By Regulating Inflammation

... asthmatic response in mice. “Nrf2 is critical for proper response to allergens in lungs and maintenance of a balance between ROS production. Antioxidant capability regulated by Nrf2 may be a major determinant of susceptibility to allergen-mediated asthma,?says Biswal. “Nrf2 regulated pathways seem to inter...

Genetic variation alters response to common anti-clotting drug

... a heart attack, stroke, or major surgery. But the proper dose of warfarin can vary greatly and can be hard to predict. Some of this variability may boil down to a recently identified gene involved in blood clotting, according to a new study published in the June 2 issue of The New England Journal of Medici...
