New Theory Links Gene Length to Cellular Decline

A gene’s length may have more to do with aging than particular “aging genes.” Reduced expression of long genes may be the cause of many aging-related changes, according to researchers writing an opinion piece that was published in the journal Trends in Genetics on March 21st, 2023.

Unraveling the Role of Gene Length in Aging

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.
