Area of Science:

  • Genetics
  • Developmental Biology
  • Gerontology

Background:

  • Aging is viewed as a genetically programmed continuum of development.
  • Environmental and epigenetic factors significantly influence aging, particularly later in life.
  • Aging shares commonalities with diseases like cancer and neurodegeneration across species.

Purpose of the Study:

  • To explore the genetic and environmental underpinnings of aging.
  • To investigate the link between lifespan, stress resistance, and oxidative damage.
  • To understand the mechanisms driving healthy aging and longevity.

Main Methods:

  • Review of developmental genetics theories.
  • Analysis of genetic mutations and their phenotypic effects.
  • Examination of oxidative stress and DNA methylation as aging biomarkers.
