Epigenetic clock analysis of cellular senescence According to a molecular biomarker of aging known as epigenetic clock,[14] the three major types of cellular senescence, namely replicative senescence, oncogene-induced senescence and DNA damage-induced senescence are distinct because induction of replicative senescence (RS) and oncogene-induced senescence (OIS) were found to be accompanied by epigenetic aging of primaryContinue reading “Pursuing longevity: Epigenetic clock and cellular senescence”
