Genetic interactions are the key to understanding complex traits

In recent years, genetic studies have uncovered hundreds of DNA variations linked to common diseases, such as cancer or diabetes, raising the prospect that scientists can gauge disease risk based on information in an individual's genome.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

Scientists shed light on how DNA is unwound so that its code can be read

Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

Prion switching in response to environmental stress

If you have had a hard day at work, you may change your eating habits, perhaps favoring comfort food, but you don't suddenly develop the ability to eat the plate and cutlery.

FDA strengthens safety of Sucraid (sacrosidase) oral solution

The U.S. Food and Drug Administration today issued an expedited approval of a supplemental application that allows for changes in the manufacturing of Sucraid (sacrosidase) Oral Solution.

Biologists identify genes that prevent changes in physical traits due to environmental changes

New York University biologists have identified genes that prevent physical traits from being affected by environmental changes.

Yeast-based vaccine induces immune responses and reduces tumor size in mice

Scientists have found that vaccination with a heat-killed, non-toxic yeast that is genetically engineered to manufacture a common tumor protein can induce specific and repeated anti-tumor immune responses in mice.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

The cell size problem

For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide?

Researchers pinpoint when a cell is ready to reproduce

For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide, In research conducted in budding yeast ( Saccharomyces cerevisiae ), scientists at Rockefeller University have now identified the cellular event that marks the moment when a cell knows it is big enough to commit to cell division and spawn genetic replicas of itself.

Latest sequencing targets for NHGRI

The National Human Genome Research Institute (NHGRI) has announced several new sequencing targets including the Northern white-cheeked gibbon (Nomascus leucogenys).

Important new global mechanism for gene repression

Most of the time in most cells of the body, the great majority of genes are silenced, locked away within the compacted but orderly material that makes up chromosomes.

Cheap way to produce expensive malaria drug well on the way

U.S. researchers say a cheap way to produce an expensive but effective malaria drug is well on the way.

Fibril shape is the basis of prion strains and cross-species prion infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell.
