Age, Sequence, and DNA Methylation are Culprits of Lactose IntoleranceMay 20, 2016While fine wine and aged cheese are culinary delights, some of us who dine on dairy often start to go a bit ‘sour’ with age and develop lactose intolerance. Thankfully, to aid our mental digestion of such a foul fate, a collaborative effort between Toronto and Lithuania has shown the molecular mechanism of why we can […]
Stress Accelerates Epigenetic AgeingDecember 18, 2015The epigenetic clock has developed faster than the iWatch: it can predict biological age from select CpGs, which when compared with chronological age, gives a metric known as Δ-age. The greater the difference, the greater the acceleration of epigenetic age, which indicates variation in the rate of senescence between people. To understand this variation and […]
Stem Cell Scientists Use Cell Reprogramming Techniques to Study AgingOctober 22, 2015“Work harder, eat less, and, I’m begging you, get a haircut!” A face-to-face meeting between a younger and an older version of yourself would surely be filled with sage advice on how to live life and grow old gracefully. Many scientists wish to recreate such a meeting between young and old neurons to study aging and […]
Sorting the Old from the New – Cellular Barriers Keeps Stem Cells YoungSeptember 29, 2015Alongside smartphones, coffee shops, and bars, we all also need properly functioning stem cells to survive and prosper. Indeed, the stem cell theory of aging posits that the malfunctioning of stem cells in our later years, and not all that caffeine and alcohol, is the major cause of human aging. So how do we keep […]
Nukes Aid Stem Cell Research in the HeartJune 20, 2015Researchers from the laboratory of Jonas Frisén at the Karolinska Institutet in Sweden have recently put radioactive carbon from nuclear bomb tests to good use, testing whether the adult human heart has the ability to repair itself. So how does that work? Well, a sharp rise in atmospheric radioactive carbon in the 1950-60s due to […]
Could Chromatin Organization be the Key to Eternal Youth?May 13, 2015For thousands of years great men such as Alexander the Great and Ponce de León have searched far and wide in their search for the fountain of youth and the hope of eternal life. But where they previously failed, an enterprising group of scientists may have now just succeeded! A report published recently in Science […]
Epigenetic Clock Goes from Analog to iWatchFebruary 6, 2015Tick tock…we all know that life is a battle against the inevitability of time. But wouldn’t it be great if you could get a real idea of how your cells are aging? It may just help make 20 the new 30, that is when it comes to your chance of death. And that’s the ambitious […]
Understanding How H3K4me1 Affects the Ageing Stem CellDecember 4, 2014Even though we don’t want to admit it, we all see changes in ourselves as the years pass by. A few more inches round the waistline here, and a little less muscle tone there, all due to a little less exercise and a little more food and drink! But what changes occur in our stem […]
Environmental enrichment stimulates neural 5hmC dynamicsSeptember 17, 2014Judging from the luxurious lifestyles of the rich and famous, it would seem there’s no denying the wonders of an enriched environment. Even at an epigenetic scale, enhancing your environment properly and with a bit of personal restraint leads to improvements in the brain aplenty, including learning and memory. A team from Emory University characterized the […]
The Aging Methylome and CancerMarch 15, 2010Between the body aches and wrinkles, most of us don’t need to be reminded that getting old is the most significant health risk. A new report in Genome Research explains how promoters of certain Polycomb group protein target genes (PCGTs) become increasingly hypermethylated as we age; leaving us more at risk for cancer. The link […]
