A new study has found that chronic kidney disease can accelerate biological aging. But fear not! Researchers have also discovered that kidney transplantation slows down this aging process, although dialysis does not have the same effect. In fact, these findings have led to the development of a more accurate “epigenetic clock” for measuring biological age, even in people without kidney disease. If only we could turn back time, Cher would be so proud!
In the world of aging, there are two categories: your age according to the calendar and your age according to biology. It’s like knowing what date it is and how much your body has aged. Simple, right? Well, not really. The study of biological aging is still in its infancy, but researchers are making great strides, thanks to the concept of the elusive “epigenetic clock.” This clock involves examining our DNA for signs of aging and comparing it to our actual age. It’s like trying to determine our biological age using the world’s most complex wristwatch.
Now, a team of researchers from the Karolinska Institutet in Sweden and the University of Glasgow in Scotland claim to have developed a more accurate and fit epigenetic clock. And how did they do it? By studying people with chronic kidney disease, of course! It turns out that this condition produces signs of accelerated aging, making it the perfect guinea pig for this study. Forget about time machines; these researchers have found a way to measure aging using kidney disease patients!
The research team conducted a study involving 400 people with chronic kidney disease and 100 healthy individuals for comparison. They used existing measures of biological age to see how dialysis and kidney transplantation affected patients’ epigenetic clocks. Surprise, surprise! People with chronic kidney disease on dialysis experienced faster biological aging, while those who received a kidney transplant saw a slower aging process. Dialysis may give temporary relief, but transplantation is like hitting the rewind button on aging.

But hold on a minute! Not everyone agrees with these findings. Dr. Nathan Goodyear, an integrative medicine practitioner and medical director, believes that the stress and immune dysfunction associated with surgery, along with the chronic immune suppression required post-transplantation, could actually accelerate aging. It’s like the immune system is trying to speed up the aging process while also hitting the brakes. Talk about a roller coaster ride!
The researchers discovered that the existing epigenetic clocks were not completely accurate. It’s as if they were trying to measure time with faulty watches. So, they developed a new epigenetic clock based on “methylation tagging,” a natural byproduct of aging where methyl groups accumulate in our DNA, affecting gene transcription. It’s like having tiny elves dancing on a typewriter, changing the way our genes work. This new clock is designed to work in both healthy and diseased tissue. It’s like a timeless piece that can accurately measure our age, no matter what our body is going through.
But here’s the thing: not everyone believes in the power of epigenetic clocks. Some scientists think they’re just a passing trend, like fidget spinners or pet rocks. Charles Brenner, chair of Diabetes and Cancer Metabolism at City of Hope and the chief scientific officer at ChromaDex, argues that using biomarkers in blood is unnecessary when we can compare our fitness to others our age. It’s like saying, “Who needs a wristwatch when you can just ask someone for the time?” Fair point, Charles.
Nevertheless, it’s important to remember that our lifestyle choices play a significant role in the aging process. Up to 93% of aging can be attributed to factors such as diet, exercise, sleep, and environmental influences. It’s like having a “Choose Your Own Adventure” book for aging. We have the power to write our own story and slow down the hands of time. So, go ahead and eat right, stay active, sleep well, and avoid alcohol and drugs. And maybe, just maybe, consider adding some nicotinamide riboside (a form of vitamin B3) to your routine. It’s like giving your body a secret weapon against aging and metabolic stress.
Life may be a never-ending countdown, but with a better understanding of biological aging and the help of epigenetic clocks, we can make every second count. So, let’s seize the day and embrace the challenge of aging gracefully. And remember, age is just a number – a number that we can influence with our lifestyle choices. Let’s choose to live life to the fullest, one moment at a time!
