Epigenome editing based treatment: Progresses and challenges

Epigenome editing is emerging as a transformative approach in clinical treatment, enabling precise modifications to gene expression without altering the underlying DNA sequence. The ongoing transition of epigenome editing techniques from foundational research to clinical applications highlights several key strategies. These include targeted DNA methylation/demethylation, histone modification, and transcriptional regulation. These approaches offer the potential for durable and reversible gene expression modulation, paving the way for precisely tailored therapies for genetic and complex diseases. Here, we review pioneering research, technological advancements, granted patents, and clinical trials that have been reported during the past decade. By synthesizing current research and development efforts, this review aims to provide insights into the promising landscape of epigenome editing and its potential to promote therapeutic interventions.
