Human deoxyribonucleases (DNases) are crucial enzymes involved in DNA breakdown. Recent research reveals novel DNases, their mechanisms, and roles in diseases and programmed cell death, with potential medical applications.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Immunology

Background:

  • Mammalian deoxyribonucleases (DNases) have been studied for over 60 years.
  • Recent research has identified novel human DNases, including lactoferrin.
  • Understanding DNase function is critical due to their roles in disease and cell death.

Purpose of the Study:

  • To review recent advancements in human deoxyribonuclease research.
  • To elucidate the mechanisms of DNA hydrolysis by various DNases.
  • To summarize the biological roles and medical applications of human DNases.

Main Methods:

  • Literature review of recent studies on human DNases.
  • Analysis of structural and mechanistic data for key DNases.
  • Synthesis of information on DNase involvement in disease pathogenesis and apoptosis.
