The renin-angiotensin system (RAS), crucial for bodily functions, is present in invertebrates. This suggests the RAS evolved very early in life's history.

Area of Science:

  • Comparative physiology
  • Evolutionary biology
  • Biochemistry

Background:

  • The renin-angiotensin system (RAS) is a vital hormone system in vertebrates.
  • RAS plays key roles in blood pressure regulation, fluid balance, and cardiovascular function.

Purpose of the Study:

  • To review the components and functions of the renin-angiotensin system (RAS) in invertebrates.
  • To explore the evolutionary origins of the RAS.

Main Methods:

  • Literature review of existing studies on RAS in invertebrates.
  • Comparative analysis of RAS components across different invertebrate species.

Main Results:

  • Components of the RAS have been identified in various invertebrate species.

  • The invertebrate RAS is involved in osmoregulation, reproduction, memory, and immune responses.
  • Homologs of RAS elements are found in invertebrates, indicating an ancient origin.

    • Conclusions:

    • The renin-angiotensin system (RAS) is not exclusive to vertebrates and is conserved in invertebrates.
    • The presence of RAS in invertebrates suggests its fundamental role predates vertebrate evolution.
    • Further research into invertebrate RAS can provide insights into the system's ancestral functions.
