Do long genes hold the key to understanding the genetic underpinnings of aging?

Review explores the connection between gene length and aging, summarizing recent findings that link reduced long-gene expression to age-related decline and potential anti-aging strategies. Review: Gene length could be a critical factor in the aging of the genome .

The expression of longer genes occurs less frequently with age than the expression of shorter genes. This phenomenon has been termed "gene length-dependent transcription decline" (GLTD). Long-gene expression Understanding the genetic underpinnings of aging has long been one of the major focal points of biological science research.

Numerous studies aim to identify the genes that play a central role in aging. However, identifying the genetic basis of aging has been a challenge. One of the theories consistently proposed by various groups of researchers is that with age, the expression of longer genes becomes less frequent than that of shorter genes.

One team of researchers called this theory the gene length-dependent transcription decline, where aging is linked to the physical properties of the genes, such as their length, rather than their function. This approach contrasts with the traditional focus on gene function, suggesting that the physical structure of the genome plays a critical role in aging. Numerous i.
