Researchers Build Model Protocell Capable of Copying DNA (6/5/2008)

Four billion years ago, modern cells were absent on our still-young planet. The simple protocells that are thought to have given rise to Earth's earliest life forms were plentiful, but likely no more than a bit of genetic material surrounded by a hollow membrane. ...> Full Article

Scientists devised a genetic screen to identify genes responsible for fat storage in cell of fruit flies, and potentially other species. ...> Full Article

Life without TORC is one big struggle (5/13/2008)

Humans and fruitflies - those pesky little buggers that are irresistibly attracted to overripe fruit - share more than a sweet tooth. Both rely on the same insulin-regulated molecular pathway to maintain their energy balance when starved for food ...> Full Article

Genetic 'tag team' keeps cells on cycle (5/11/2008)

By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle. ...> Full Article

Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer (3/4/2008)

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier. In a series of elegant experiments in mice, researchers at Rockefeller University have now discovered a tiny RNA molecule that helps create this barrier. The results not only yield new insight into how skin first evolved, but also suggest how healthy cells can turn cancerous. ...> Full Article

Radiation From Mobile Phones Changes Protein Expression In Living People, Study Suggests (2/26/2008)

A new study completed by the Finnish Radiation and Nuclear Safety Authority (STUK) on effects of mobile phone radiation on human skin strengthens the results of the human cell line analyses: living tissue responds to mobile phone radiation. ...> Full Article

Gene at intersection of stem cells, immunity (2/25/2008)

A gene that "wakes up" the blood system's stem cells in times of stress also plays an important role in protecting against infection, said researchers from Baylor College of Medicine in Houston, the National Institute of Allergy and Infectious Disease and Duke University Medical School in a report that appears in the journal Cell Stem Cell. ...> Full Article

New Genetic Syndrome Linked to Missing DNA (2/20/2008)

People who lack a certain large segment of DNA have a previously unrecognized syndrome characterized by mental retardation, seizures, and slight physical abnormalities, according to a genetic analysis conducted by HHMI investigator Evan E. Eichler at the University of Washington School of Medicine and a team of international collaborators. The deleted DNA segment is responsible for just a small percentage of cases of mental retardation, but "when you think about how common mental retardation is," Eichler says, "this deletion has a significant impact on human health." ...> Full Article

BMP protein maintains cross talk between cells that control hair growth (2/18/2008)

Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose unique collection of proteins ultimately instruct epithelial stem cells to make hair. ...> Full Article

Lab characterizes gene essential for prenatal development of nervous system (2/3/2008)

The Stowers Institute's Trainor Lab has demonstrated the role of a gene important to the embryonic development of the nervous system, a process that requires coordination of differentiation of immature neural cells with the cycle of cell division that increases their numbers. Until now, the mechanisms regulating these distinct cellular activities have been poorly understood. The findings will be published in the Feb. 15 issue of Development. ...> Full Article
