Kim J, Min S, Seol CA, Seo EJ
Ann Lab Med (Jul 2025)

Single nucleotide polymorphism-based chromosomal microarray analysis (CMA) can detect regions of homozygosity (ROHs), which may be associated with medical conditions; however, limited ROH data, especially in East Asians, complicates clinical interpretations. We characterized ROH distributions and frequencies in a Korean population using CMA, highlighting clinically relevant findings, including suspected uniparental disomy (UPD), using standardized criteria.]]> Wed, 31 Dec 1969 19:00:00 EST Complementary genetic and epigenetic changes facilitate rapid adaptation to multiple global change stressors. Brennan RS, deMayo JA, Finiguerra M, Baumann H, Dam HG, Pespeni MH
Proc Natl Acad Sci U S A (Jul 2025)

To persist under unprecedented rates of global change, populations can adapt or acclimate. However, how these resilience mechanisms interact, particularly the role of epigenetic variation in long-term adaptation, is unknown. To address this gap, we experimentally evolved the foundational marine copepod for 25 generations under ocean acidification, warming, and their combination and then measured epigenomic, genomic, and transcriptomic responses. We observed clear and consistent epigenomic and genomic divergence between treatments, with epigenomic divergence concentrated in genes related to stress response and the regulation of transposable elements. However, epigenetic and genetic changes were inversely related and occurred in different regions of the genome; levels of genetic differentiation (F) were up to 2.5Ã higher in regions where methylation did not differ between treatments compared to regions with significant methylation changes. This negative relationship between epigenetic and genetic divergence could be driven by local inhibition of one another or distinct functional targets of selection. Finally, epigenetic divergence was positively, though weakly, associated with gene expression divergence, suggesting that epigenetic changes may facilitate phenotypic change. Taken together, these results suggest that unique, complementary genetic and epigenetic mechanisms promote resilience to global change.]]> Wed, 31 Dec 1969 19:00:00 EST The myoblast methylome: multiple types of associations with chromatin and transcription.

Epigenetics (Dec 2025)

Epigenetic changes are implicated in development, repair, and physiology of postnatal skeletal muscle (SkM). We generated methylomes for human myoblasts (SkM progenitor cells) and determined myoblast differentially methylated regions (DMRs) for comparison to the epigenomics and transcriptomics of diverse cell types. Analyses were from global genomic and single-gene perspectives and included reporter gene assays. One atypical finding was the association of promoter-adjacent hypermethylation in myoblasts with transcription turn-on, but at downmodulated levels, for certain genes (., and ). In contrast, brain-specific was in repressed chromatin and silent in most cell types but linked to hypermethylated DMRs specifically in myoblasts. The -linked DMRs might be needed because of the overlapping or nearby binding of myogenic differentiation protein 1 (MYOD). We found genome-wide overlap of DMRs with MYOD or CCCTC-binding factor (CTCF) binding sites in myoblasts that is consistent with the importance of MYOD, as well as CTCF, in organizing myoblast transcription-enhancing chromatin interactions. We also observed some gene upregulation correlated with a special association of regional DNA hypomethylation with H3K36me3, H3K27ac, and H3K4me1 enrichment. Our study highlights unusual relationships between epigenetics and gene expression that illustrate the interplay between DNA methylation and chromatin epigenetics in the regulation of transcription.]]> Wed, 31 Dec 1969 19:00:00 EST Matrix Stiffness Regulates TGFÎ²1-Induced Î±SMA Expression via a G9a-LATS-YAP Signaling Cascade. Sankhe CS, Sacco JL, Crunkleton VL, GarcÃa MD, Bierowski MJ, Soares DVR, Karnick JA, Cecco RL, Abbasi A, Kirigo J, Wood TK, Gomez EW
FASEB Bioadv (Jul 2025)

Extracellular matrix stiffness is enhanced in cancer and fibrosis; however, there is limited knowledge on how matrix mechanics modulate expression and signaling of the methyltransferase G9a. Here, we show that matrix stiffness and transforming growth factor (TGF)-Î²1 signaling together regulate G9a expression and the levels of the histone mark H3K9me2. Suppressing the activity and expression of G9a attenuates TGFÎ²1-induced alpha smooth muscle actin (Î±SMA) and N-cadherin expression and cell morphology changes in mammary epithelial cells cultured on stiff substrata. Knockdown of G9a increases the expression of large tumor suppressor kinase 2 (LATS2) and decreases the nuclear localization of yes associated protein (YAP). Furthermore, inhibition of LATS promotes an increase in YAP nuclear localization and Î±SMA expression, while inhibition of YAP attenuates Î±SMA expression. Overall, our findings indicate that a G9a-LATS-YAP signaling cascade regulates mammary epithelial cell response to matrix stiffness and TGFÎ²1.]]> Wed, 31 Dec 1969 19:00:00 EST Differential methylation patterns in cord blood associated with prenatal exposure to neighborhood crime: an epigenome-wide association study and regional analysis. Martin CL, Chen J, D'Alessio AS, Ward-Caviness CK, Ye A, Lodge EK, Ghastine L, Dhingra R, Jima DD, Murphy SK, Hoyo C
Epigenetics (Dec 2025)

Exposure to prenatal social stressors during pregnancy is associated with adverse birth outcomes and has been linked to epigenetic changes in DNA methylation (DNAm); however, less understood is the effect of neighborhood-level stressors like crime during pregnancy on offspring DNAm. Using data from the Newborn Epigenetic Study, we conducted epigenome-wide and regional analyses of the association between exposure to neighborhood crime and DNAm in offspring cord blood using Illumina's HumanMethylation450k BeadChip among 185 mother-offspring pairs. Prenatal exposure to neighborhood crime at the census block group level was mapped to participants' residential addresses during the gestational window from the date of last menstrual period to delivery. Models for the epigenome-wide and regional analyses were adjusted for maternal age, race/ethnicity, education, smoking, cell-type composition, and offspring sex. Genetic influence and gene expression enrichment were assessed using methylation quantitative trait loci (mQTLs) and expression quantitative trait methylation (eQTMs) analyses. Functional enrichment was determined using Gene Ontology and KEGG databases. We did not find evidence of epigenome-wide associations between prenatal neighborhood crime exposure and DNAm; however, we identified nine differentially methylated regions (DMRs) comprising 51 CpG sites associated with neighborhood crime. CpG sites within significant differentially methylated regions were associated with mQTLs at birth and eQTMs upon further examination. KEGG analysis identified a significant Th1 and Th2 cell differentiation pathway. Our results suggest potential links between prenatal neighborhood crime exposure and offspring DNAm; however, additional research is needed in larger cohorts across wider geographic areas to confirm our results.]]> Wed, 31 Dec 1969 19:00:00 EST The emerging role of multiomics in aging research. Ruden DM
Epigenomics (Jul 2025)

Aging is a complex biological process involving coordinated changes across multiple molecular systems. Traditional reductionist approaches, while valuable, are insufficient to capture the full scope of aging's systemic nature. Multiomics - integrating data from genomics, transcriptomics, epigenomics, proteomics, and metabolomics - provides a comprehensive framework to study aging as an interconnected network. In this Perspective, I explore how multiomic strategies, particularly those leveraging epigenomic and single-cell data, are reshaping our understanding of aging biology. Epigenetic alterations, including DNA methylation and histone modifications, are not only hallmarks but also powerful biomarkers of biological age. I discuss advances in multiomic aging clocks, cross-tissue atlases, and single-cell spatial technologies that decode aging at unprecedented resolution. I also build on a prior review I wrote with colleagues, Epigenomics. 2023;15(14):741-754, which introduced the concept of pathological epigenetic events that are reversible (PEERs) - epigenetic alterations linked to early-life exposures that predispose to aging and disease but may be therapeutically modifiable. This Perspective examines how PEERs and multiomics intersect to inform biomarkers, geroprotective interventions, and personalized aging medicine. Finally, I highlight integration challenges, ethical concerns, and the need for standardization to accelerate clinical translation. Together, these insights position multiomics as a central pillar in the future of aging research.]]> Wed, 31 Dec 1969 19:00:00 EST use capsules, transporters, mobile genetic elements, and other evolutionary adaptations to survive antibiotics exposure in the absence of resistance genes.

Jbeli AH, Crouser ED, Bhargava M
Curr Opin Pulm Med (Jul 2025)

Sarcoidosis is a complex, multisystem disease characterized by granulomatous inflammation and variable clinical outcomes. Its pathogenesis and progression are driven by intricate biological interactions, involving a complex interplay between patient-specific factors such as genetic background, sex, and environmental exposures, as well as epigenetic modifications that regulate gene expression and protein levels. These interconnected layers ultimately drive immune response to yet unidentified trigger(s), culminating in granuloma formation and, in some cases, with an aberrant repair response leading to irreversible organ dysfunction in some cases. In this review, we aim to synthesize recent multiomics research that unravels the underlying biological networks, offering a systems-level understanding of sarcoidosis.]]> Wed, 31 Dec 1969 19:00:00 EST Host-microbe multi-omics and succinotype profiling have prognostic value for future relapse in patients with inflammatory bowel disease.

Gut Microbes (Dec 2025)

Crohn's disease (CD) and ulcerative colitis (UC) are chronic relapsing inflammatory bowel disorders (IBD), the pathogenesis of which is uncertain but includes genetic susceptibility factors, immune-mediated tissue injury and environmental influences, most of which appear to act via the gut microbiome. We hypothesized that host-microbe alterations could be used to prognostically stratify patients experiencing relapses up to four years after endoscopy. We therefore examined multiple omics data, including published and new datasets, generated from paired inflamed and non-inflamed mucosal biopsies from 142 patients with IBD (54âCD; 88 UC) and from 34 control (non-diseased) biopsies. The relapse-predictive potential of 16S rRNA gene and transcript amplicons (standing and active microbiota) were investigated along with host transcriptomics, epigenomics and genetics. While standard single-omics analysis could not distinguish between patients who relapsed and those that remained in remission within four years of colonoscopy, we did find an association between the number of flares and a patient's succinotype. Our multi-omics machine learning approach was also able to predict relapse when combining features from the microbiome and human host. Therefore multi-omics, rather than single omics, better predicts relapse within 4âyears of colonoscopy, while a patient's succinotype is associated with a higher frequency of relapses.]]> Wed, 31 Dec 1969 19:00:00 EST and are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation.

Epigenetics (Dec 2025)

Genomic imprinting is the parent-of-origin specific monoallelic expression of genes that result from complex epigenetic interactions. It is often achieved by monoallelic 5-methylcytosine, resulting in the formation of differentially methylated regions (DMRs). These show a bias towards oocyte-derived methylation and survive reprogramming in the pre-implantation embryo. Imprinting is widespread in the human placenta. We have recently performed whole-genome screens for novel imprinted placenta-specific germline DMRs (gDMRs) by comparing methylomes of gametes, blastocysts and various somatic tissues, including placenta. We observe that, unlike conventional imprinting, for which methylation at gDMRs is observed in all tissues, placenta-specific imprinting is associated with transient gDMRs, present only in the pre-implantation embryo and extra-embryonic lineages. To expand the list of imprinted genes subject to placenta-specific imprinting, we reinvestigated our list of candidate loci and characterized two novel imprinted genes, and , both of which display polymorphic imprinting. Interrogation of placenta single-cell RNA-seq datasets, as well as cell-type methylation profiles, revealed complex cell-type specificity. We further interrogated their methylation and expression in placental samples from complicated pregnancies, but failed to identify differences between intrauterine growth restricted or pre-eclamptic samples and controls, suggesting they are not involved in these conditions.]]> Wed, 31 Dec 1969 19:00:00 EST Accounting for differences between Infinium MethylationEPIC v2 and v1 in DNA methylation-based tools. Zhuang BC, Jude MS, Konwar C, Yusupov N, Ryan CP, Engelbrecht HR, Whitehead J, Halberstam AA, MacIsaac JL, Dever K, Tran TK, Korinek K, Zimmer Z, Lee NR, McDade TW, Kuzawa CW, Huffman KM, Belsky DW, Binder EB, Czamara D, Korthauer K, Kobor MS
Life Sci Alliance (Sep 2025)

The recently launched Illumina Infinium MethylationEPIC v2.0 (EPICv2), successor of MethylationEPIC v1.0 (EPICv1), retains most of the probes in EPICv1, while expanding coverage of regulatory elements. The concordance between the two EPIC versions in DNA methylation-based tools has not yet been investigated. To address this, DNA methylation was profiled on both versions using matched blood samples across four cohorts spanning early to late adulthood. High concordance between versions at the array level but variable agreement at the individual probe level was noted. A significant contribution of the EPIC version to DNA methylation variation was observed, though it was to a smaller extent compared with sample relatedness and cell-type composition. Modest but significant differences in DNA methylation-based estimates between versions were observed, irrespective of the data preprocessing method used. Adjustments for EPIC version or calculation of estimates separately for each version largely mitigated these version-specific discordances. This work emphasizes the importance of accounting for EPIC version differences in research scenarios, especially in meta-analyses and longitudinal studies that require data harmonization across versions.]]> Wed, 31 Dec 1969 19:00:00 EST Using long-read sequencing to detect and subtype a case with Temple syndrome. Dada S, Akbari V, Hejla D, Shen Y, Dixon K, Choufani S, Weksberg RA, Boerkoel CF, Stewart L, Schlade-Bartusiak K, Strong E, Fox D, Gamu D, Gibson WT, Jones SJM
J Med Genet (Jul 2025)

Temple syndrome is an imprinting disorder resulting from abnormal genomic or epigenomic aberrations of chromosome 14 including maternal uniparental disomy (matUPD), paternal deletion of 14q32, or aberrant methylation of the imprinting control regions at 14q32. Understanding the underlying molecular mechanism is essential to understanding the recurrence risk and physical effects. Currently, diagnosis requires the detection of aberrant methylation and copy number loss via methylation-sensitive assays such as methylation-specific multiplex ligation-dependent probe amplification, and short tandem repeat analysis to detect matUPD and the presence of epimutation. Therefore, a one-step approach that can detect aberrant methylation and underlying genetic mechanisms would be of high clinical value. Here we use nanopore sequencing to delineate the molecular diagnosis of a case with Temple syndrome. We demonstrate the application of nanopore sequencing to detect aberrant methylation and underlying genetic mechanisms simultaneously in this case, thus providing a proof of concept for a one-step approach for molecular diagnosis of this disorder.]]> Wed, 31 Dec 1969 19:00:00 EST Multigenerational exposure to DEHP drives dysregulation of imprinted gene Snurf to impair decidualization. Tan L, Gao R, Su Y, Zhang Y, Geng Y, Liu Q, Ma Y, Chen X, Li F, He J
J Hazard Mater (Aug 2025)

Phthalate-induced female reproductive health issues, particularly those related to di (2-ethylhexyl) phthalate (DEHP), are growing global concerns. Although most studies have focused on single-generation exposure, studies on prolonged DEHP exposure across multiple generations are limited. This study assessed the effects of multigenerational DEHP exposure on endometrial decidualization, which is crucial for embryo implantation. The results showed that sustained DEHP exposure over three generations exacerbated decidualization injury and led to adverse pregnancy outcomes. RNA sequencing revealed upregulation of the imprinted gene Snurf in the decidua, with changes that may not depend on alterations in DNA methylation. Knockdown of Snurf significantly alleviated in vitro decidualization deficiency induced by mono(2-ethylhexyl) phthalate (MEHP), the biologically active metabolite of DEHP. Proteomic analysis and the AlphaFold 3 algorithm indicated that Stn1 is a downstream target of Snurf, with silencing Stn1 resensitizing Snurf-knockdown stromal cells to MEHP. Human decidual stromal cells (hDSCs) from healthy participants showed sensitivity to MEHP, with the inhibition of decidualization. Epidemiological data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) indicated a positive association between DEHP exposure and female infertility. This study highlighted the cumulative toxic effects of multigenerational DEHP exposure on female reproduction and revealed the contribution of imprinted genes.]]> Wed, 31 Dec 1969 19:00:00 EST VEGFA Stop-Gained Variant Deteriorates Cardiac Remodeling in Myocardial Infarction.

Circ Genom Precis Med (Jul 2025)

A sustained dosage of VEGFA (vascular endothelial growth factor A) is crucial for angiogenesis in both homeostasis and cardiovascular diseases. CUG-initiated alternative translation is a conserved mechanism for producing mature VEGFA. Genetic surveys have identified stop-gained variants predicted to prematurely terminate CUG-initiated translation without affecting ATG-initiated translation. However, the impacts of these variants on the vasculature in steady-state and disease conditions remain unknown.]]> Wed, 31 Dec 1969 19:00:00 EST CT Biomarkers for Phenotypic Biological Aging: Emerging Concepts and Advantages. Lee MH, Garrett JW, Liu D, Pickhardt PJ
Radiographics (Aug 2025)

Aging is a complex phenomenon reflecting the time-dependent accumulation of damage that results in progressive structural and functional decline, disease risk, and death. Chronological age (CA) is an imperfect measure of health but remains an important driver of health care decisions. Biological age (BA) is a construct that attempts to provide a more holistic evaluation of the cumulative effects of aging and aging-related disease. The emergence of "omics"-based aging clocks (eg, epigenomics) has improved BA estimation, but imaging remains underutilized. CT biomarkers of muscle, fat, aortic calcification, and bone are examples of biomarkers of aging that can be used to construct a BA model (ie, CT-based biological age). As opposed to cellular and subcellular "frailomics" used in existing BA models, CT biomarkers are accessible and reproducible and reflect big-picture net phenotypic effects of aging at the tissue level (eg, using tissue segmentation). Recent technological advancements and improvements in artificial intelligence (AI) technologies have transformed our understanding of aging, and rapid automated AI tools enable scaling of image-based approaches for population-level impact. The understandable nature of explainable AI imaging tools instills trust in a model's prediction compared with opaque black box methodologies. Automated imaging-based body composition tools also can be applied opportunistically in either a retrospective or prospective fashion without the need for additional imaging, specialized testing, or patient time. Using a CT-based phenotypic approach to BA estimation is a practical example of opportunistic imaging that could be used to improve existing medical decision making and risk prediction for individual patient and societal benefit in ways that existing frailomics have failed.

Biochem Soc Trans (Jul 2025)

Pluripotent stem cells (PSCs) possess the remarkable ability to self-renew and differentiate into nearly any cell type, making them invaluable for both research and therapeutic applications. Despite these powerful attributes, PSCs are vulnerable to genetic and epigenetic instabilities that can undermine their reliability and safety. While genetic abnormalities can be routinely monitored with established guidelines, epigenetic instabilities often go unchecked. Among the most recurrent epigenetic defects in PSCs are errors in genomic imprinting - a process that governs parent-of-origin-specific monoallelic expression of certain genes through differential marking of the two parental alleles by DNA methylation. When disrupted, it becomes a source of a dozen developmental conditions known as imprinting diseases. In PSCs, once imprinting errors arise, they remain throughout cellular differentiation, casting uncertainty over the use of PSC-derived cells for disease modelling and regenerative medicine. In this review, we provide an overview of imprinting defects in both mouse and human PSCs, delving into their origins and consequences. We also discuss potential correction strategies that aim to enhance imprinting stability, ultimately paving the way for safer, more reliable PSC use in research and clinical applications.]]> Wed, 31 Dec 1969 19:00:00 EST A Possible More Precise Management Unit Delineation Based on Epigenomic Differentiation of a Long-Distance-Migratory Marine Fish Scomberomorus niphonius. Liu S, Gao Y, Long X, Li K, Gutang Q, Xie H, Wang J, Tian J, Liang B, Lin J, Liu W
Mol Ecol Resour (Aug 2025)

Understanding population structure and adaptive history is critical for designing appropriate management regulations for fisheries and conserving adaptive potential for the future. However, this is not easy for marine fish, especially those with long-distance migration abilities. In this study, we constructed a high-quality reference genome for Japanese Spanish mackerel (Scomberomorus niphonius) and explored its population structure using whole genomic and epigenomic data. Despite the high depth of the sequence data, we failed to identify geographical genetic differentiation of Japanese Spanish mackerel across Chinese coastal waters. However, whole-genome bisulphite sequencing can classify this species into the Bohai-Yellow Sea group and the East China Sea-South China Sea group. Genes involved in embryonic skeletal system development, limb morphogenesis functions, and adult locomotory behaviour were differentially methylated in the southern (Zhanjiang, ZJ) and northern (Western Dalian, WDL) populations and may play important roles as drivers of population structure in Japanese Spanish mackerel. Our study not only provides the first reference genome of the Japanese Spanish mackerel and sheds light on population differentiation at the epigenomic level, but also provides a methylome-based framework for population structure analyses of marine fish with long-distance migration ability. These findings are expected to facilitate the development of scientific programmes for the successful conservation of marine fishery resources.]]> Wed, 31 Dec 1969 19:00:00 EST Decoding hybridization barriers: the molecular and genetic orchestration of the triploid block in Arabidopsis thaliana. Aguirre M, Loperfido D, Ezquer I
BMC Plant Biol (Jul 2025)

Plant evolution has been greatly influenced by polyploidization phenomena. Polyploid plants yield more and are more resistant to unfavorable environments than their diploid relatives. The triploid block, a postzygotic barrier that causes failure of endosperm development and thus seed arrest, often prevents polyploid breeding. Alterations in the parental dose in interploidy crosses alter endosperm development by changing the correct maternal: paternal ratio (2m:1p) that this tissue requires to properly fulfill its proliferation and cellularization. After many years of research, the study of epigenetic regulation of gene expression during seed development has greatly increased our understanding of the triploid block. In plants, epigenetic regulation of genes has been shown to play a critical role in transcriptional control. This may be important for identifying novel and unexpected epigenetic mechanisms in the plant genome. Recent advances in understanding how epigenetic mechanisms control the expression of imprinted genes in seeds have contributed to understanding how different seed compartments interact at fertilization for successful seed formation. We here also review the potential role of maternally derived sporophytic tissues (seed coat) in the establishment of the triploid block. We also present a data analysis that includes spatiotemporal expression patterns of key genes involved in controlling hybridization barriers. This review provides an overview of the triploid block in plants, discussing how understanding its epigenetic regulation could offer new strategies to overcome hybridization barriers. We explore how these insights may enhance crop productivity and resilience.]]> Wed, 31 Dec 1969 19:00:00 EST Applications of single-cell analysis in immunotherapy for lung cancer: Current progress, new challenges and expectations. Xiao N, Liu H, Zhang C, Chen H, Li Y, Yang Y, Liu H, Wan J
J Adv Res (Aug 2025)

Lung cancer is a prevalent form of cancer worldwide, presenting a substantial risk to human well-being. Lung cancer is classified into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The advancement of tumor immunotherapy, specifically immune checkpoint inhibitors and adaptive T-cell therapy, has encountered substantial obstacles due to the rapid progression of SCLC and the metastasis, recurrence, and drug resistance of NSCLC. These challenges are believed to stem from the tumor heterogeneity of lung cancer within the tumor microenvironment.]]> Wed, 31 Dec 1969 19:00:00 EST Integrating gut microbiome and neuroplasticity genomics in alcohol use disorder therapy.
