Researcher In RNA Biology Makes Waves By Challenging Current Thinking (1/21/2008)

In the January 18th issue of Molecular Cell, Case Western Reserve University School of Medicine researcher Kristian E. Baker, Ph.D. challenges molecular biology's established body of evidence and widely-accepted model for nonsense-mediated messenger ribonucleic acid (mRNA) decay. With her collaborator, Ambro van Hoof, Ph.D. of The University of Texas Health Sciences Center, Baker directly tested the "faux 3' UTR" model and proved it could not explain how cells recognize and destroy deviant mRNA. This landmark discovery will redirect mRNA research and expand opportunities for new discoveries in understanding the cells' ability to protect itself from these potential errors. ...> Full Article

Team finds an economical way to boost the vitamin A content of maize (1/21/2008)

A team of plant geneticists and crop scientists has pioneered an economical approach to the selective breeding of maize that can boost levels of provitamin A, the precursors that are converted to vitamin A upon consumption. This innovation could help to enhance the nutritional status of millions of people in the developing world. ...> Full Article

Tiny Genetic Differences Have Huge Consequences (1/20/2008)

A study led by McGill University researchers has demonstrated that small differences between individuals at the DNA level can lead to dramatic differences in the way genes produce proteins. These, in turn, are responsible for the vast array of differences in physical characteristics between individuals. ...> Full Article

Genetically modified carrots provide more calcium (1/17/2008)

Genetically modifying carrots to express increased levels of a gene that enables the transport of calcium across membranes of plant cells can make the vegetables a better source of calcium, said researchers at Baylor College of Medicine in Houston and the Vegetable and Fruit Improvement Center at Texas A&M University. Their report appears today in the Proceedings of the National Academy of Sciences. ...> Full Article

Molecular Evolution: Mice Given Bat-like Forelimbs Through Gene Switch (1/16/2008)

A research team led by Dr. Richard Behringer at MD Anderson Cancer Center reports that they have successfully switched the mouse Prx1 gene regulatory element with the Prx1 gene regulatory region from a bat -- and although these two species are separated by millions of years of evolution -- the resulting transgenic mice displayed abnormally long forelimbs. ...> Full Article

Recurrent genetic deletion linked to autism (1/9/2008)

Loss of a small portion of chromosome 16, known as 16p11.2, is significantly associated with autism report researchers from the University of Chicago Medical Center, the University of Illinois at Chicago, and the Roswell Park Cancer Institute in an article, published Dec. 21, 2007, online by the journal Human Molecular Genetics. ...> Full Article

Mechanics of gene transcription (1/9/2008)

The molecular machinery behind gene transcription -- the intricate transfer of information from a segment of DNA to a corresponding strand of messenger RNA -- isn't stationed in special "transcription factories" within a cell nucleus, according to Cornell researchers. Instead, the enzyme RNA polymerase II (Pol II) and other key molecules can assemble at the site of an activated gene, regardless of the gene's position. ...> Full Article

Report Urges Development of Genomic Technologies for Identifying Toxic Chemicals and Understanding Individual Vulnerabilities (10/9/2007)

A new report from the National Research Council recommends that government agencies enhance their efforts to incorporate genomic data into risk assessments of chemicals and medicines, and calls for a concerted effort to fully develop these methods' potential to protect public health. Chemicals and drugs often cause health problems by altering gene expression and other cell activity, and research on these processes -- called toxicogenomic research -- could eventually lead to more-sensitive toxicity tests that can supplement current tests, the report says. Toxicogenomic tests can also pinpoint individuals with genetic vulnerabilities and help them avoid chemicals or medications that might make them ill. ...> Full Article

Genetically Engineered Corn May Harm Stream Ecosystems (10/9/2007)
