Mechanism by which Signaling Pathways Regulate Growth and Differentiation of Adult Muscle Stem Cells is Revealed (1/8/2008)

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. Although the signaling pathways controlling muscle regeneration are fairly well known, how these signals lead to altered chromatin structure remains undiscovered. A group of scientists at the Burnham Institute for Medical Research in La Jolla, CA, analyzed the mechanism by which certain cellular signaling cues cause epigenetic modifications when released within the regenerative microenvironment, thus controlling the expression of genes that regulate growth and differentiation of muscle stem cells that repair injured muscle. ...> Full Article

Enzyme Mutation Disrupts Organ Growth (11/29/2007)

The cellular mechanism that turns DNA into all of the thousands of proteins that make up a human body is itself both intricate and interesting.
