Insulin-like growth factors and their potential role in cardiac epigenetics

Area of Science:

• Cardiovascular Science
• Epigenetics
• Molecular Biology

Background:

• Cardiovascular disease (CVD) is a leading global cause of mortality, responsible for 17.3 million deaths annually.
• CVD accounts for a significant portion of healthcare expenditures in developed nations.
• While genetics and pathophysiology of CVD are well-studied, the role of epigenetics remains less understood.

Purpose of the Study:

• To review the emerging role of epigenetics in cardiovascular diseases.
• To highlight the involvement of insulin-like growth factors I and II (IGF-I and IGF-II) as key epigenetic mediators.
• To discuss the implications for understanding CVD origins and developing novel therapeutic strategies.

Main Methods:

• Literature review focusing on epigenetic mechanisms in CVD.
• Analysis of studies investigating the role of IGF-I and IGF-II in cardiac pathophysiology.
• Synthesis of current knowledge on environmental influences on CVD epigenetics.

Main Results:

• Epigenetic modifications are increasingly recognized as critical determinants in the development of CVD.
• IGF-I and IGF-II signaling pathways are implicated in major cardiovascular conditions, including heart failure and cardiac hypertrophy.
• Environmental factors significantly impact epigenetic profiles, contributing to CVD risk.

Conclusions:

• Epigenetics, particularly mediated by IGF-I and IGF-II, represents a vital area for understanding CVD.
• Targeting epigenetic mechanisms offers promising avenues for innovative prevention and treatment strategies for cardiovascular diseases.
• Further research into the interplay between environment, epigenetics, and CVD is essential.
