molecular clock

Introduction

• the term "molecular clocks" in context of human aging encompasses 3 major concepts:
  • epigenetic clocks (DNA methylation-based biomarkers of biological age)
  • circadian molecular clocks (transcriptional machinery governing 24-hour rhythms)
  • cellular aging clocks (transcriptional biomarkers of aging & mortality)
• both are strongly linked to aging processes through distinct mechanisms
