The making of a fat cell

...llows preadipocytes to cease dividing and cluster, forming bona fide fat cells. Integrins are a superfamily of cell surface proteins that are involved in binding to the extracellular matrix, a meshwork of protein and fiber supports outside of cells that can influence their behavior.

Newly recognized gene mutation may reduce seeds, resurrect plants

...ids play a role in preventing plant dehydration in forming cells' membranes, in molecular signaling and in energy storage. A still-to-be revealed lipid associated with formation of the cuticle that coats plant surfaces may signal whether a seed develops to maturity or is aborted early due to a defective embr...

An essential regulator of body weight revealed

..., while NPY/AgRP neurons were still developing and forming connections with neighboring cells, the mice ate normally and maintained a normal body weight. Their findings indicated that if NPY/AgRP neurons are eliminated before they become fully functional, then animals somehow compensated, maintaining feeding...

Researchers learn how blood vessel cells cope with their pressure-packed job

...st other flexible materials react to stretching by forming stress wrinkles parallel to the direction in which they are being pulled. However, the healthy bovine aorta endothelial cells did not behave that way in tests performed in the laboratory of Shu Chien, a coauthor of the PNAS paper and a professor of b...

Normal chromosome ends elicit a limited DNA damage response

...e tucked in and shielded by a phalanx of proteins, forming a protective "cap". Ironically, to form this protective structure at the end of chromosomes, nature solicited help from the very same repair machinery whose misguided repair attempts the cap is supposed to hold at bay, reports the Salk team, led by ...

Give thanks for the cranberry, say dental researchers

'Acid rain' and forest mass: Another perspective

...cteria are capable of oxidising the compound, thus forming nitrate and liberating protons that acidify the soil. Amongst the effects of the deposition of these compounds on the forest mass are the well-known nutrition disorders of the same. One classic effect is that of cation deficit (particularly magnesium...

Ancient trans-Atlantic swarm brought locusts to the New World

... economically important insects, and is capable of forming massive swarms that devastate crops. DNA shows that ancestors of the desert locust flew across the Atlantic and gave rise to a diverse group of New World species. "If we were standing on the coast of Africa, we might have these swarms of locusts hea...

Zooming in on the protein-conducting channel

...coli attached to a ribosome that contained a newly forming protein segment. The ribosome is the massive protein-RNA complex that constitutes the cell's protein-making machinery. Mitra explored the structure of this PCC-ribosome complex using three-dimensional cryogenic electron microscopy (cryo-EM), as well...

Mining biotech's data mother lode

...protein, the protein folds up into a unique shape, forming a 3D structure. This structure can only interact, or fit, with some proteins, but not others, like pieces of a jigsaw puzzle. BioGrid's protein interaction software includes a database of the 20,000 known protein structures and uses that database to...

Genes involved in biofilms

For the identification of the genes involved in t...

Researchers make long DNA 'wires' for future medical and electronic devices

...ed a process for uncoiling long strands of DNA and forming them into precise patterns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devices, said L. James Lee, professor of chemical and biomolecular engineering at Ohio State University. In the early online ...

Nano springs eternal; Protozoan 'engine' posts nano records

To find out how fast and how hard Vorticella recoils, France and colleagues used modern microscopes and tools to measure the force and speed of the spring. This is one powerful engine, France reports. The spasmoneme's contraction is mea...

Tracking the memory trace

...always in the same place. "It's not as if we are forming memories that are then being written to a "hard disk" area of the brain, and it's there and recalled from the same location at any time after learning," said Davis. "We now think that different areas of the brain have dominion over small intervals of...
