Botox finds new wrinkle in brain communication
National Institutes of Health researchers used the popular anti-wrinkle agent Botox to discover a new and important role for a group of molecules that nerve cells use to quickly send messages. This novel role for the molecules, called SNARES, may be a missing piece that scientists have been searching for to fully understand how brain cells communicate under normal and disease conditions.

Scientists create genetically altered mice to model human disease
Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.

It slices, it dices, it silences: ADAR1 as gene-silencing modular RNA multitool
RNA, once considered a bit player in the grand scheme by which genes encode protein, is increasingly seen to have a major role in human genetics. In a study presented in the April 25 issue of the journal Cell, researchers from The Wistar Institute discovered how the RNA-editing protein, ADAR1, also combines with the protein called Dicer to create microRNA (miRNA) and small interfering (siRN

New molecule heralds hope for muscular dystrophy treatment
There's hope for patients with myotonic dystrophy. A new small molecule developed by researchers at the University of Illinois has been shown to break up the protein-RNA clusters that cause the disease in living human cells, an important first step toward developing a pharmaceutical treatment for the as-yet untreatable disease.

Researchers identify key cellular organelle involved in gene silencing
RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes — from development to physiology to stress response.

Link between inherited endocrine tumor syndrome and much-studied cell pathway

A check on tension
Ludwig researchers Arshad Desai and Christopher Campbell, a post-doctoral fellow in his laboratory, were conducting an experiment to parse the molecular details of cell division about three years ago, when they engineered a mutant yeast cell as a control that, in theory, had no chance of surviving. Apparently unaware of this, the mutant thrived.

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed group of proteins, which in human cells are implicated in some cancers.

Circadian rhythms keep time for all living things, from regulating when plants open their flowers to foiling people when they try to beat jet lag. Day-night cycles are controlled through ancient biological mechanisms, evolutionarily speaking, so in essence, a human has the same internal clock as a fly does.
