Search for macular degeneration genes narrows

...onent, most believe the cause will be found in the interplay of several genes combined with environmental factors, such as smoking and diet. Swaroop says that this study is significant because it confirms locations that have been suggested by other researchers, noting that cross-validation is important for com...

Alcohol-dependence gene identified

...olved in psychiatric disorders is that there is an interplay between genetic and environmental factors," she says. "A person can carry all kinds of genes that predispose them to alcohol dependence, but if they never take a drink, they won't become an alcoholic."...

...microbiology, biochemistry and spectroscopy. "The interplay between life and its surrounding environment is amazingly complex," Storrie-Lombardi said, "and detecting the signatures of living systems in Dr. Fisk's study demanded close cooperation among scientists in multiple disciplines and resources from mul...

Gliomas' 'molecular fingerprint' predicts how aggressive tumor will be

...of the genes. Disease can occur when the intricate interplay of thousands of proteins goes awry; the goal of molecularly targeted therapy is to set the process right again in a way that specifically corrects the problem without causing damage to surrounding normal cells. Using a process developed by Capri...

Cognitive performance influenced by gene for prion protein (also affected by mad cow disease)

Cognitive abilities are influenced by an interplay of genes and environment. With regard to the genetic component, multiple genes are assumed to be responsible for interindividual variation in cognitive abilities. Despite tremulous progress in molecular genetics, little is known about specific genes ...

Study provides new insights into emerging theory of gene regulation

...cess to the DNA. They suspect that the coordinated interplay of a number of specific enzymes is required to turn on a particular gene. Now, in a new study using the techniques of structural biology, investigators at The Wistar Institute have shown in detail how two enzymes work together to activate a specific ...

MicroRNAs - Tiny molecules shape up plants

...w have pinpointed, for the first time, the precise interplay between a particular microRNA, called "Jaw", and its targets. "For several years, we had a mutant plant that overproduced a large RNA of unknown function. Surprisingly, this RNA did not seem to make a protein, like most other RNAs do. After we read C...

UT Southwestern researchers define regions of human genes highly prone to mutation

...ficant byproduct of this research into the complex interplay between mutation and selection is that Ms. Horvath has revealed some clear rules that can contribute to the design and execution of genetic association studies. This will become an important component of the solution to the currently intractable prob...

Crabs switch skeleton types

...e legs and claws almost as efficiently as when the interplay between muscles and the outer shells causes movement. In a preliminary test to determine if hydrostatic pressure was necessary for newly molted crabs to maintain their shape and support, researchers made a small hole in a crab's cuticle. Because it ...

Genome researcher analyze chromosome 7

In their analysis of the highly polished reference sequence, Dr.Wilson and his colleagues identified approximately 1,150 protein-coding genes on chromosome ...

Research breakthrough identifies 291 genes associated with asthma

...in asthma. The discovery that asthma involves the interplay of 291 genes "has tremendous therapeutic and diagnostic implications," says Marc Rothenberg, MD, PhD, director of Allergy and Immunology at Cincinnati Children's and the study's senior author. "Each gene may represent a target for drug development,...

Study of thyroxine transporter molecule shows how key hormone hitches a lift round body

... "This is an unprecedented example of the complex interplay between the binding of fatty acids and thyroxine to the protein. Although fatty acids and thyroxine compete with one another to bind to several sites on the protein, there is also an element of cooperation through the creation of an additional bindin...

The roots of human behavior? AAAS and The Hastings Center host a public meeting

..., emotion, and behavior result from a very complex interplay of multiple gene, environmental factors, and chance." Behavioral genetics has often gotten a bad rap, and not without reason. Around the turn of the last century, researchers in the United States and Great Britain sought inherited causes for all sort...
