...l particles and saw activation of some of the same gene groups in the animals tissue. Exactly how air pollutants cause cardiovascular injury is poorly understood, Nel said. But we do know that these particles are coated with chemicals that damage tissue and cause inflammation of the nose and lungs. Vas...

Researchers watch antibiotics, bacteria meet at atomic level

...A polymerase is the enzyme responsible for setting gene expression in motion, a process called transcription. Without a properly functioning RNA polymerase, a cell will die. RNA polymerase spends most of its working hours as the elongation complex, Artsimovitch said. The complex makes RNA's messages one...

News tips from the Journal of Neuroscience

...VMAT is a member of the toxin-extruding antiporter gene family with the interesting acronym TEXAN. Accordingly, Caudle et al. examined whether reduced VMAT2 leads to degeneration of dopamine neurons. The authors examined mice that expressed 5% of the normal protein (VMAT2 LO). These mice showed elevated r...

By examining PPAR functions in vivo, our work reveals an unexpected link between diet, inflammation and the quality of mothers milk, exp...

A novel molecular dictator 'with a conscience' discovered

...with a conscience. "The dictator is a specific gene suppressor called YY1, which has the therapeutically appealing capacity to differentiate between certain cell types when it goes about its activity," says Professor Khachigian. This key finding has just been published in the world's premier cardio...
