Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Protein within neurons in the amygdala controls development of alcohol withdrawal symptoms and drinking behaviors

Doctors may one day be able to control alcohol addiction by manipulating the molecular events in the brain that underlie anxiety associated with alcohol withdrawal, researchers at the University of Illinois at Chicago College of Medicine and the Jesse Brown VA Medical Center report in the March 5 issue of the Journal of Neuroscience.
