Mitochondria, the power plants of the cell, carry their own DNA, encoding a few proteins essential to mitochondrial operation. Mutational damage to these genes can result in broken mitochondria that take over cells and cause the export of oxidizing ... [Continue Reading]
LRS as a Negative Regulator of Muscle Regeneration
Myostatin is perhaps the best known suppressor of muscle growth and regeneration. Myostatin loss of function mutants, both natural and artificial, and in a number of mammalian species, are heavily muscled as a result of differences in regulation of ... [Continue Reading]
Fibrosis as a Consequence of Processes of Aging
Fibrosis is a malfunction of tissue maintenance and regeneration in which scar-like collagen deposits form, disrupting tissue structure and function. It almost always occurs in later life, even in fibrotic conditions clearly caused by environmental ... [Continue Reading]
