Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • The plasminogen/plasminogen activator (P/PA) system is a key regulator of extracellular proteolysis.
  • This system plays critical roles in physiological and pathological processes.

Purpose of the Study:

  • To review the multifaceted involvement of the P/PA system in cancer progression.
  • To highlight its roles in tumor invasion, cell migration, growth factor presentation, and angiogenesis inhibition.

Main Methods:

  • Literature review of studies investigating the P/PA system in cancer.
  • Analysis of P/PA system components and their functions in tumor microenvironments.

Main Results:

  • The P/PA system facilitates tumor cell invasion and migration through matrix degradation.
