Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biochemistry

Background:

  • Prohibitin (PHB) is localized to mitochondria, potentially involved in maintaining mitochondrial function and preventing senescence.
  • The function of nuclear-localized PHB is debated, with proposed roles in tumor suppression, cell proliferation, cell-cycle regulation, and apoptosis.
  • Cell-associated PHB in the gastrointestinal tract is linked to protection against infection and inflammation.

Purpose of the Study:

  • To explore the multifaceted roles of Prohibitin (PHB) in cellular processes.
  • To investigate the potential of PHB as a therapeutic target for various diseases.

Main Methods:

  • Literature review and analysis of existing research on Prohibitin (PHB) functions.
  • Examination of PHB's localization (mitochondrial, nuclear, cell-surface) and associated functions.
