Ribosomal DNA Methylation Patterns Reveal When Aging Begins
BUFFALO, NY — July 23, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on June 16, 2025, titled “rDNA copy number variation and methylation from birth to sexual maturity.” In this study, led by first authors Alina Michler and Sarah Kießling along with corresponding author Thomas Haaf from Julius Maximilians University in Germany, researchers explored how ribosomal DNA (rDNA) copy number and methylation change from infancy to adolescence. They discovered that the epigenetic changes often associated with aging in adults do not occur before sexual maturity…
