Epigenetic reprogramming
The authors of a recent review published in Ageing Research Reviews summarize the research on epigenetic reprogramming and its potential as a rejuvenation therapy [1]. Epigenetics in aging Aging leads to changes in the epigenome. Those changes can lead to alterations in gene regulation, affecting cellular homeostasis, and can play a role in age-associated phenotypes....
Epigenetics
Steve Horvath, Vera Gorbunova, Alejandro Ocampo, and their team have used partial reprogramming to repair DNA damage in a mouse model. They published their findings in Frontiers in Aging. Building a path to rejuvenation Yamanaka Factors - Opportunities for RejuvenationDrs. Takahashi and Yamanaka showed that they could use Oct4, Sox2, Klf4, and c-Myc (OSKM) to reprogram...
Information DNA
In a new paper, Sinclair and his co-authors outline a theory arguing that epigenetic changes are the underlying cause of aging [1]. When cells get old It is not every day that one of the most prominent geroscientists presents a new theory of aging. David Sinclair of Harvard, along with two co-authors, Yuancheng Ryan Lu...
Entropy
In Nature Communications, researchers have explained how epigenetic drift and disorder are associated with shorter lifespans across species. When randomness is a problem We have previously reported on research demonstrating that epigenetic clocks are most likely to be measuring noise. This paper builds on that concept, citing previous research showing that this gradual epigenetic drift...
Chromatin
Researchers publishing in Nature Aging have investigated one of the core biological reasons behind the decline of stem cells' ability to proliferate. Heterochromatin and euchromatin The genetic component of cells is comprised of two main parts: heterochromatin and euchromatin. Heterochromatin is largely silent, as it is a tightly packed mass that consists primarily of non-coding...
Old mouse and young mouse
For the first time, scientists have shown that letting young and old mice share blood leads to a significant lifespan extension in the old mouse [1]. Rejuvenation by young blood Since the dawn of civilization, young blood has been credited with healing and rejuvenating powers, and its value has been demonstrated by modern science. In...
