Cardiac epigenetics, a burgeoning field of research within cardiovascular science, investigates the intricate molecular modifications influencing gene expression and function in the heart. Unlike genetic changes, epigenetic alterations do not involve modifications to the underlying DNA sequence but instead affect how genes are activated or silenced. Understanding cardiac epigenetics provides crucial insights into the mechanisms that regulate cardiovascular health and disease. Researchers in this field explore how factors such as lifestyle, environmental exposures, and aging can induce changes in epigenetic marks, influencing cardiac development, function, and responses to various stressors. Unraveling the complexities of cardiac epigenetics holds significant promise for advancing our comprehension of cardiovascular diseases and may pave the way for innovative therapeutic strategies tailored to address specific epigenetic signatures associated with heart health.
