Candida albicans Genome Fully Annotated

...tiny hollow sacs along the airways where the blood takes in oxygen and discards carbon dioxide. The processes by which alveoli recover from damage are complex and incompletely understood, Zander said. Previous research showed that type II pneumocytes in the lungs are known to play a central role, but the ...

Researchers make headway in mystery of migraines

...rstanding of how genetic mutations cause migraines takes us one step closer to the development of improved treatments, providing hope to millions of migraine sufferers. ...

Bioinformatics reveals new gene regulation system

...alled positional clustering. Positional clustering takes advantage of the fact that functionally related gene sequences (such as the genes for Nrd and its transcription factor) frequently inhabit the same 'neighborhood' of the chromosome. "If you are looking in one genome, many genes will be neighbors by ...

Speak up: Louder neurons form more connections

...e work, published in the April 21 issue of Nature, takes advantage of tiny, see-through zebrafish. Stephen Smith, PhD, professor of molecular and cellular physiology at the Stanford University School of Medicine, and his graduate student Jackie Hua immersed 3-day-old fish in a breathable, Jell-O-like subst...

When it comes to cell entry, being average has its advantages

...ptors to bind to the virus. If it is too small, it takes too much energy to bend the cell membrane as it engulfs the invader." When the team compared the implications of their theory to actual experimental observations with cells, they found broad agreement. "The theory is fundamentally sound ?a significa...

Montreal researchers probe the genetic basis of memory

...spearheaded the research project. "For example, it takes most people a number of attempts to learn new things, such as memorizing a passage from a book. The first few times we may initially succeed in memorizing the passage, but the memory may not be stored completely in the brain and we will have to stud...

Study: Harmless virus kills some cancers

Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers. "Our results suggest that adeno-associated virus type 2 (AAV2)...

Major advance made on DNA structure

...sible DNA sequences ?a discovery that in one sense takes up where Watson and Crick left off, after outlining in 1953 the double-helical structure of this biological blueprint for life. One of the fundamental problems in biochemistry is to predict the structure of a molecule from its sequence ?this has bee...

New protein vital for immune response is found in surprise location

...n the complex series of biochemical reactions that takes place when the body is infected with a virus. Researchers at UT Southwestern, led by microbiologist Dr. Michael Gale, and elsewhere have previously found that when an RNA virus invades a cell, a protein called RIG-I first intercepts the virus and bi...

Their work, which takes advantage of a new technique for visualizing tissues in their natural state, provides new insights into the molecular basis of muscle relaxation, and perhaps its activation too. "We have solved the structure of the array of miniature motors that fo...

Promiscuous Catalytic Activity Possessed by Novel Enzyme Structure

...s the basis for new drugs. The enzyme, named Orf2, takes chemical building blocks known as small aromatic molecules and changes them by adding a fat-like molecule called a prenyl group. That modification can have a huge impact on where the aromatic molecule goes within the cell, and what sort of effects it...
