Phase separation of epigenetic landscape in cardiovascular diseases

The pathogenesis of cardiovascular diseases (CVDs) is intricate, with liquid-liquid phase separation (LLPS) considered a crucial regulatory mechanism. Epigenetics is closely intertwined with cardiovascular diseases, involving mechanisms such as DNA methylation, histone modifications, and non-coding RNAs (ncRNAs) that play pivotal roles in cardiovascular disease progression and regression. It is known that specific proteins and mRNAs associated with epigenetic modifications exhibit LLPS characteristics, influencing cardiovascular diseases. Consequently, targeting epigenetic modifications to modulate LLPS emerges as a promising strategy for cardiovascular diseases treatment. This review delves into the regulatory impact of liquid-liquid phase separation on cardiovascular diseases, with a specific focus on the epigenetic landscape. The current study sought to investigate the relationship between epigenetic landscape and phase separation in cardiovascular diseases development, as well as their therapeutic implications. • Liquid-liquid phase separation regulation of cardiovascular diseases. • Liquid-liquid phase separation and epigenetic interactions in cardiovascular diseases. • Epigenetic regulation of targeted liquid-liquid phase separation for cardiovascular diseases.
