Epigenetics And Gene Silencing
Epigenetics is the study of changes in gene silencing that occur without changes in the genes themselves. As noted by Medical News Today, much of the work on genetic therapies for age-related conditions - and the aging process itself - has focused on altering genes. However, "many genes in our bodies are permanently turned off as part of normal development. [Sometimes] that process goes awry, turning off genes that should otherwise remain active. The new field of epigenetic therapy [aims] to switch these genes back on." Interesting stuff, and a reminder that all newly discovered knowledge of human genetics and biochemistry will eventually help in the fight to cure aging.
