Therapeutic Role of Chinese Medicine Targeting Nrf2/HO-1 Signaling Pathway in Myocardial Ischemia/Reperfusion Injury

Area of Science:

• Cardiovascular Research
• Pharmacology
• Integrative Medicine

Background:

• Acute myocardial infarction (AMI) is a leading cause of mortality worldwide.
• Reperfusion therapy, while essential, can paradoxically worsen cardiac damage via myocardial ischemia/reperfusion injury (MI/RI).
• Developing effective strategies to mitigate MI/RI is a critical unmet need in cardiovascular medicine.

Purpose of the Study:

• To provide a comprehensive overview of the nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway.
• To elucidate the role of the Nrf2/HO-1 pathway in the pathophysiology of MI/RI.
• To review the therapeutic potential of Chinese medicine in modulating the Nrf2/HO-1 pathway for MI/RI treatment.

Main Methods:

• Literature review of existing research on MI/RI.
• Analysis of the structure and function of the Nrf2/HO-1 signaling pathway.
• Synthesis of studies investigating Chinese medicine's effects on the Nrf2/HO-1 pathway in the context of MI/RI.

Main Results:

• The Nrf2/HO-1 pathway is a key regulator of cellular processes involved in MI/RI, including inflammation, oxidative stress, and apoptosis.
• Chinese medicine exhibits multi-component, multi-pathway, and multi-target properties beneficial for MI/RI.
• Emerging evidence supports the use of Chinese medicine to activate the Nrf2/HO-1 pathway, offering cardioprotective effects.

Conclusions:

• The Nrf2/HO-1 pathway represents a promising therapeutic target for reducing MI/RI.
• Chinese medicine holds significant potential as an adjuvant therapy for AMI by modulating the Nrf2/HO-1 pathway.
• Further research into specific Chinese medicinal compounds and their mechanisms is warranted to optimize MI/RI treatment strategies.
