Epigenetic Alterations and Reprogramming Potential in Aging
March 5, 2019
The role of epigenetics, which determine how your genes are expressed, is being increasingly implicated in aging, as is the potential of therapies that revert epigenetics back to those of a younger person. What are epigenetic alterations? The DNA in each of our cells is identical,
Rejuvenating Aged Brains by Waking Up Dormant Stem Cells
March 4, 2019
Researchers from the University of Luxembourg and the German Cancer Research Center have rejuvenated stem cells in the brains of old mice. The rejuvenated stem cells appear to improve regeneration in areas of damaged or diseased brain tissue. A new way to model stem cells A
Boosting Cellular Housekeeping with Exercise and Fasting
February 28, 2019
In order to remain healthy and functional, cells have a number of maintenance systems that help them to dispose of metabolic waste and unwanted proteins. Autophagy is perhaps the best-known example of how cells purge their waste, and another is the ubiquitin-proteasome system (UPS). Researchers are
Excessive Cell Size Contributes to Senescence
February 19, 2019
In a new study [1], researchers have identified the reason why cells become defective when they grow too large and why protein creation fails when cells grow larger than their original healthy size, as is typically seen in aged and senescent cells. They demonstrate that in
