Elysium Health has joined forces with Mayo Clinic to study the “associations between circulating nicotinamide adenine dinucleotide (NAD+) levels in healthy adults and senescent cell burden, and to develop novel epigenetic measures of cellular senescence.” One of the prominent contributions to aging is cellular senescence, or cellular deterioration. Think of senescent cells as zombie cells that impact surrounding healthy cells. At present, there isn’t an accurate way to measure the efficacy of compounds meant to clear senescent cells out of the body. With the research by Elysium Health and Mayo Clinic, they hope to “explore the relationship between NAD+ levels and cellular senescence, and aim to identify a signal from which to develop novel epigenetic measures of cellular senescence and subsequently commercialize them.”
