DNA methylation is a critical regulatory mechanism of gene expression, influencing various human diseases and traits. While traditional expression quantitative trait loci (eQTL) studies have helped elucidate the genetic regulation there growing need to explore environmental influences on expression. Existing methods such as PrediXcan FUSION focus genotype-based associations but overlook impact factors. To address this gap, we present MOSES (methylation-based association), novel approach that utilizes identify environmentally regulated genes associated with traits or without relying measured involves training, imputation, association testing. It employs elastic-net penalized regression models estimate influence CpGs SNPs (if available) We developed compared four versions incorporating different data: (1) cis-DNA within 1 Mb promoter regions, (2) both cis-SNPs cis-CpGs, 3) cis- part trans- (±5Mb away) from regions), 4) long-range (±10 regions. Our analysis using nasal epithelium white blood cell data Epigenetic Variation Childhood Asthma in Puerto Ricans (EVA-PR) study demonstrated MOSES, particularly version (MOSES-DNAm 10 M), significantly outperformed existing like PrediXcan, MethylXcan, Biomethyl predicting MOSES-DNAm M identified more differentially expressed (DEGs) atopic asthma, those involved immune pathways, highlighting its superior performance uncovering genes. Further application lung tissue idiopathic pulmonary fibrosis (IPF) patients confirmed robustness versatility across tissues. represents an innovative advancement studies, leveraging capture factors By CpGs, provides predictive accuracy capabilities methods. This offers valuable insights into complex interplay between genetics environment, enhancing our understanding disease mechanisms potentially guiding therapeutic strategies.

Frontotemporal Lobar Degeneration (FTLD) represents a spectrum of clinically, genetically, and pathologically heterogeneous neurodegenerative disorders characterised by progressive atrophy the frontal temporal lobes brain. The two major FTLD pathological subgroups are FTLD-TDP FTLD-tau. While majority cases sporadic, heterogeneity also exists within familial cases, typically involving mutations in MAPT, GRN or C9orf72, which is not fully explained known genetic mechanisms. We sought to address this gap investigating effect epigenetic modifications, specifically DNA methylation variation, on genes associated with risk different subtypes. compiled list using text-mining databases literature searches. Frontal cortex profiles were derived from three datasets containing FTLD-tau: FTLD1m (N = 23) type A C9orf72 mutation carriers TDP Type C sporadic FTLD2m 48) FTLD-Tau MAPT carriers, B FTLD3m 163) supranuclear palsy (PSP) corresponding controls. To investigate downstream effects further, we then leveraged transcriptomic proteomic for controls examine gene protein expression levels. Our analysis revealed shared promoter region hypomethylation STX6 across FTLD-tau subtypes, though largest size was observed PSP compared (delta-beta -32%, adjusted-p value=0.002). dysregulation Additionally, performed detailed examination subtypes without presence nominally significant differentially methylated CpGs variable positions genes, often unique patterns consequences gene/protein carriers. highlight contribution at regions regulating previously FTLD, including STX6. analysed relationship mechanism increase our understanding how these mechanisms interact FTLD.

Early and accurate diagnosis significantly improves the chances of disease survival. DNA methylation (5mC), major modification in human genome, is now recognized as a biomarker immense clinical potential. This due to its ability delineate precisely cell-type, quantitate both internal external exposures, well tracking chronological biological components aging process. Here, we survey current state predictor traits disease. includes Epigenome-wide association study (EWAS) findings that inform Methylation Risk Scores (MRS), EpiScore long-term estimators plasma protein levels, machine learning (ML) derived clocks. These all highlight significant benefits accessible peripheral blood surrogate measure. However, detailed biopsy analysis real-time also empowering pathological diagnosis. Furthermore, moving forward, this multi-omic biobank scale era, novel insights will be enabled by amplified power increasing sample sizes data integration.
