Key research themes
1. How do epigenetic modifications mediate gene-environment interactions, and what role do they play in human health and disease?
This research area investigates the molecular mechanisms through which epigenetic changes, such as DNA methylation and histone modifications, mediate the interaction between environmental exposures and genetic information to regulate gene expression without altering DNA sequence. Understanding these mechanisms is critical to elucidate the etiology of complex diseases, the persistence of phenotypes, and transgenerational inheritance patterns.
Key finding: This seminal work synthesizes accumulating evidence that DNA methylation patterns, particularly hypermethylation of tumor suppressor genes (e.g., p16INK4a, p14ARF, MGMT), constitute early and tumor type-specific events in... Read more
Key finding: This interdisciplinary review identifies that epigenetic markers function as mediators facilitating communication between environmental signals ('outside') and genomic responses ('inside'). It elucidates how authors... Read more
Key finding: Providing a comprehensive overview, this review confirms that epigenetic modifications—including DNA methylation and histone post-translational alterations—serve as mechanisms by which environmental and genetic factors... Read more
Key finding: This paper elucidates the bidirectional link between metabolism and epigenetics, demonstrating that metabolic enzymes and metabolites serve as substrates and cofactors for epigenetic modifications, influencing gene expression... Read more
2. What are the current technological and therapeutic approaches to epigenome editing, and how do they enable precise modulation of gene expression?
This theme centers on advanced methodologies for targeted modulation of epigenetic marks, emphasizing the development and optimization of epigenome editing technologies such as CRISPR/dCas9-fusion proteins and small molecule inhibitors. It evaluates the utility, specificity, delivery challenges, and therapeutic potential of these approaches, which hold promise for durable gene expression regulation in disease treatment, including cancer and other epigenetically mediated conditions.
Key finding: This review catalogues epigenetic therapies spanning from well-established low-molecular-weight inhibitors of histone and DNA modifying enzymes (e.g., DNMTs, HDACs) to emerging programmable epigenome editors based on... Read more
Key finding: This perspective delineates the conceptual framework and operational parameters governing epigenome editing via CRISPR/dCas9 systems, underscoring their capability for locus-specific rewriting of chromatin marks to control... Read more
Key finding: This innovative work introduces a CRISPR/dCas9-based epigenetic editing approach that eschews the use of enzymatic effectors, instead employing physical steric hindrance to block endogenous DNA methylation at target sites.... Read more
3. How do environmental interventions such as diet, exercise, and grafting impact the epigenome, and what therapeutic opportunities do they present?
This theme explores applied intentional epigenetics by examining how modifiable lifestyle factors and horticultural techniques can induce beneficial epigenetic changes. Research activity includes the influence of nutrition and physical activity on metabolic disease-related epigenetic reprogramming, as well as the role of grafting in plant epigenetic communication. These studies highlight epigenetics as a dynamic interface between environment and organism function, offering avenues for preventive and therapeutic intervention.
Key finding: This review synthesizes evidence that diet and physical activity act as potent environmental modifiers of the epigenome, with impacts on DNA methylation and histone modifications linked to metabolic health outcomes. It... Read more
Key finding: The study details the epigenetic underpinnings of plant grafting, demonstrating how signals traverse graft junctions to induce epigenetic changes that regulate gene expression involved in development and stress response. It... Read more
