The ATP Synthase Deficiency in Human Diseases

Area of Science:

• Biochemistry
• Molecular Biology
• Pathophysiology

Background:

• Mitochondria are crucial for cellular energy production through oxidative phosphorylation.
• Dysfunctional ATP synthase, regardless of gene origin, is implicated in various human diseases.
• High-energy tissues like the brain, heart, and muscles are particularly vulnerable to oxidative phosphorylation defects.

Purpose of the Study:

• To review human diseases linked to altered ATP synthase gene expression.
• To elucidate the role of ATP synthase in the pathophysiology of cardiovascular and neurodegenerative diseases.
• To highlight the mitochondrial contribution to disease onset and progression.

Main Methods:

• Literature review focusing on ATP synthase gene expression and associated diseases.
• Analysis of the pathophysiological mechanisms involving ATP synthase.
• Synthesis of current knowledge on mitochondrial dysfunction in human pathologies.

Main Results:

• Altered expression of both mitochondrial and nuclear ATP synthase genes is linked to human diseases.
• ATP synthase dysfunction contributes to the pathogenesis of cardiovascular, neurodegenerative, and neurocognitive disorders.
• Mitochondrial involvement in disease cascades is independent of direct gene mutations.

Conclusions:

• ATP synthase alterations are a significant factor in a wide spectrum of human diseases.
• Understanding ATP synthase's role is key to developing therapeutic strategies for metabolic and degenerative disorders.
• Mitochondrial health is fundamental for maintaining cellular function in vital organs.
