In their new editorial, scientists James Wordsworth and Daryl Shanley from Newcastle University discuss their recently published paper on selective destruction theory (SDT). SDT recommends a mechanism of aging that is both independent of building up damage and consistent with epigenetic rejuvenation. The authors used agent-based modeling to explain how aging might go through positive choice independent of energetic costs.
” The mechanism of selective destruction is presently theoretical. In our many established model, we demonstrated that if sluggish cells induced epigenetic changes in faster cells triggering their metabolism to slow (rather than eliminating them) it not just minimized unnecessary cell death, but also additional decreased the likelihood of overactivity conditions by avoiding the spread of fast cells.”
Recommendation: “A novel theory of aging independent of damage accumulation” by James Wordsworth and Daryl Shanley, 28 July 2023, Aging.DOI: 10.18632% 2Faging.204956.
Scientist propose an unique aging theory– selective damage theory (SDT)– which explains aging as a procedure not tied to damage accumulation, providing a brand-new point of view in gerontology research study.
A brand-new editorial paper published in the journal Aging argues that in multicellular organisms, neighboring cells remain in consistent competition.
The underlying factors for aging have long remained evasive. In 1977, Thomas Kirkwood assumed that organisms might get a fitness benefit by lowering investment in somatic upkeep if this allowed them to invest more resources in more crucial processes such as recreation. The accumulation of somatic damage was therefore inevitable, and his disposable soma theory has controlled gerontology ever given that.
As our understanding of aging increases, it is becoming progressively tough to align all the aspects of aging with collecting damage. For instance, anomalies that increase damage accumulation can also increase longevity, while rejuvenation discoveries such as parabiosis and Yamanaka aspects suggest that youthfulness can be gained back without high energetic cost and despite high levels of damage.
