A growing number of EWAS have examined the effects of various dietary factors, including overall dietary patterns, specific food groups, micronutrients, and food-related metabolites, on DNA methylation (DNAm) across diverse populations. In this review, we map the landscape of nutritional EWAS, identifying the types of dietary exposures studied, the genomic regions where epigenetic signals emerge, and overarching trends across studies. Across studies, consistent associations were reported at nine CpG sites in genes such as <i>AHRR</i>, <i>CPT1A</i>, and <i>FADS2</i>, particularly in relation to fatty acid consumption, and certain diet patterns. Biological pathways enriched included fatty acid metabolism and the PPAR signaling pathway. In conclusion, our review identified a pattern of epigenetic convergence that may underlie diet-related disease risk. While promising, key knowledge gaps were also noted, including limited longitudinal follow-up, unclear causal pathways, and underrepresentation of ethnic diversity.

Here we investigated whether DNA methylation (DNAm) biomarkers of health and aging are modified during the first year of GAHT and whether these vary by treatment type. Cohort consisted of 13 trans women (TW) and 13 trans men (TM). Sampling occurred at baseline (pre-GAHT), and at 6- and 12-month follow-up. We tracked the longitudinal dynamics of three epigenetic clocks (Horvath, Hannum, PhenoAge), DNA methylation-based telomere length (DNAmTL), and DunedinPACE. At baseline, the Horvath and Hannum showed accelerated epigenetic aging, particularly pronounced among TM, while the PhenoAge and DunedinPACE showed lower pace of aging in both groups. This discrepancy may reflect possible effects of minority stress in an otherwise healthy cohort. While GAHT did not affect the three clocks, DNAmTL and DunedinPACE showed treatment-specific patterns but with notable inter-individual variability in trajectories. TW had increased DunedinPACE (estimate = 0.057, p=0.002) and slight DNAmTL gains (estimate = 0.024, ns); TM exhibited stable to slight decline in DunedinPACE (estimate = -0.013, ns), and reduction in DNAmTL (estimate = -0.057, p=0.037).

Global prevalence of the disease is increasing and patients often experience delays in diagnosis accessing effective therapy, highlighting an urgent need to develop a predictive biomarker for therapeutic response to reduce healthcare costs and disease burdens. Despite the advances to identifying genetic biomarkers for prediction of disease remission in IBD, patient responses vary widely, suggesting that inherited genetic variations alone cannot account for these differences. As autoimmune diseases like IBD are largely environmental in etiology, epigenetic modifications like DNA methylation, histone modifications, and non-coding RNAs (ncRNAs) also have the potential to be candidates for predictive biomarkers of patient disease development and treatment response. This review will explore the novel field of pharmacoepigenetics and the development of predictive epigenetic biomarkers for treatment response in IBD, highlighting new research in the field.

Additional pharmacoepigenetic cohorts with more diverse participants could help enhance current models, improving predictability of treatment response and clinical outcomes.

Asthma is characterized by changes in miRNAs that favor the differentiation of T helper 2 cells.

However, their pathogenic roles in medulloblastoma (MB) remain understudied, demanding a deeper appreciation of their participation in cancer cell dissemination and tumor progression. Herein, we show that <i>ROCK2</i> is downregulated in MB tumor samples and functionally increases migration of cell lines belonging to the SHH subgroup. A comprehensive comparative bioinformatic scrutiny of differentially expressed genes within a list of ROCK2 candidate substrates, uncovered a network of 21 dysregulated genes from which <i>DYPSL3</i> (dihydropyrimidinase-related protein 3) denoted a strong positive correlation. Enrichment analysis revealed SHH/RHOA/ROCK2/DYPSL3 as top hub genes and the intersection between two biological processes of most importance in MB: actin cytoskeleton remodeling and neuron development. Of note, evidence shows that both ROCK2 and DYPSL3, interact with RHOA and in many tumor types they act as tumor suppressors, mitigating cell spreading. Alternatively, their impaired activity leads to undifferentiated phenotypes and inappropriate cytoskeletal dynamics affecting cell shape, attachment to the extracellular matrix, and cell movement. In parallel, cell motility is considered a prototypical non-canonical response to SHH mediated by RHOA.
