Researchers from the University of California, Irvine have demonstrated that mitochondrial transplants can give cells a boost of energy and could potentially be the basis of therapies to address various cardiovascular, neurodegenerative, and metabolic diseases. The mitochondria are the powerhouses of our cells, converting the nutrients we consume into energy to be used by every...

Researchers at Stanford University have demonstrated they can rejuvenate human cells, making them more like young cells again, by rewinding an epigenetic aging clock. Epigenetic alterations and aging One of the hallmarks of aging is epigenetic alterations, which are the alterations to gene expression that our cells experience with age. They harm the fundamental functions...

The researchers of a new review have examined the relationship between cellular senescence and bone marrow cancers, looking at how senescence can ultimately fuel cancer development and how malignant cells induce senescence [1]. Senescent cells and cancer As we get older, an increasing number of our cells enter into a state known as senescence, a...

Researchers have transferred bacteria from the guts of long-lived people to those of mice, and the results have some interesting implications for healthy aging and show why maintaining a good microbial balance in the gut is one of the keys of staying healthy as we age. The gut microbiome The gut microbiome is comprised of...

As aging is a major risk factor for developing cardiovascular diseases, their prevalence rises rapidly with advancing age. A new study sheds light on our cells' declining ability to provide quality control for mitochondria, which spurs other aspects of aging. The loss of mitophagy accelerates aging The mitochondria are well-known as being the powerhouses of...

Researchers from Johns Hopkins Medicine have successfully used stem cells to repair diabetic damage to retinal blood vessels. The researchers believe that their findings will advance regenerative approaches that seek to reverse conditions such as diabetic retinopathy and other eye diseases that lead to blindness. Induced pluripotent stem cells (iPSCs) have been around for well...
