Oxidative Stress: A Possible Trigger for Pelvic Organ Prolapse

Area of Science:

• Biomedical Science
• Gynecology
• Cellular Biology

Background:

• Pelvic organ prolapse (POP) is a common condition affecting women globally, with complex and not fully understood causes.
• The integrity of pelvic supportive structures is crucial for preventing POP.
• Molecular changes in connective tissue and oxidative stress are implicated in POP pathogenesis.

Purpose of the Study:

• To emphasize the role of oxidative stress in the development of pelvic organ prolapse.
• To identify key molecular changes in pelvic supportive structures caused by oxidative stress.

Main Methods:

• Review of molecular biology research on oxidative stress effects.
• Analysis of cellular responses in pelvic supportive structures under oxidative stress conditions.

Main Results:

• Sustained mechanical stress in POP correlates with increased free radical production.
• Oxidative stress leads to mitochondrial-induced fibroblast apoptosis, dependent on stress intensity and duration.
• Oxidative stress disrupts cellular signaling, proteins, lipids, and DNA, hindering collagen and elastin synthesis.

Conclusions:

• Oxidative stress is a significant factor in the pathogenesis of pelvic organ prolapse.
• Molecular damage to pelvic supportive tissues due to oxidative stress compromises structural integrity.
