Certain substances in our bodies increase with age over time. One of these substances, a marker scientists have called 8-oxo-7,8-dihydroguanosine (8-oxoGsn) that measures oxidative cell damage, is easily measured in urine and may be a good indicator of biological – rather than chronological age – according to a new study published in Frontiers in Aging Neuroscience.
As we age, cell damage accumulates in our cells. Rates of cell damage vary from person to person, depending on genetics, lifestyle, environment, and other factors. Finding a way to measure “biological age” could help predict our risk for age-related diseases and could one day help determine if treatment measures designed to slow the aging process are effective.
This study, which was conducted by researchers in China, involved 1,228 healthy people between 2 and 90. The researchers determined that 8-oxoGsn could be easily measured through a simple urine test and is a potential biomarker for physiological age.
