Comparative Toxicogenomics of Glyphosate and Roundup Herbicidesby Mammalian Stem Cell-Based Genotoxicity Assays andMolecular Profiling in Sprague-Dawley Rats.
Mesnage R. et al.
Whether glyphosate-based herbicides (GBHs) are more potent than glyphosate alone at activating cellular mechanisms, which drive carcinogenesis remain controversial. As GBHs are more cytotoxic than glyphosate, we reasoned they may also be more capable of activating carcinogenic pathways. We tested this hypothesis by ... |
Genome-Wide Epigenomic Analyses in Patients With Nociceptive and Neuropathic Chronic Pain Subtypes Reveals Alterations in Methylation of Genes Involved in the Neuro-Musculoskeletal System
Stenz et al
Nociceptive pain involves the activation of nociceptors without damage to the nervous system, whereas neuropathic pain is related to an alteration in the central or peripheral nervous system. Chronic pain itself and the transition from acute to chronic pain may be epigenetically controlled. In this cross-sectional s... |
Environmental enrichment preserves a young DNA methylation landscape in the aged mouse hippocampus
Sara Zocher, Rupert W. Overall, Mathias Lesche, Andreas Dahl & Gerd Kempermann
The decline of brain function during aging is associated with epigenetic changes, including DNA methylation. Lifestyle interventions can improve brain function during aging, but their influence on age-related epigenetic changes is unknown. Using genome-wide DNA methylation sequencing, we here show that experiencing ... |
Riluzole Administration to Rats with Levodopa-Induced Dyskinesia Leads to Loss of DNA Methylation in Neuronal Genes
Luca Pagliaroli, Abel Fothi, Ester Nespoli, Istvan Liko, Borbala Veto, Piroska Devay, Flora Szeri, Bastian Hengerer, Csaba Barta, Tamas Aranyi
Dyskinesias are characterized by abnormal repetitive involuntary movements due to dysfunctional neuronal activity. Although levodopa-induced dyskinesia, characterized by tic-like abnormal involuntary movements, has no clinical treatment for Parkinson’s disease patients, animal studies indicate that Riluzole, w... |
Multi-omics phenotyping of the gut-liver axis reveals metabolicperturbations from a low-dose pesticide mixture in rats.
Mesnage, Robin et al.
Health effects of pesticides are not always accurately detected using the current battery of regulatory toxicity tests. We compared standard histopathology and serum biochemistry measures and multi-omics analyses in a subchronic toxicity test of a mixture of six pesticides frequently detected in foodstuffs (azoxystr... |
The insecticide permethrin induces transgenerational behavioral changeslinked to transcriptomic and epigenetic alterations in zebrafish (Daniorerio).
Blanc, Mélanie et al.
The pyrethroid insecticide permethrin is widely used for agricultural and domestic purposes. Previous data indicated that it acts as a developmental neurotoxicant and can induce transgenerational effects in non-target organisms. However, associated underlying mechanisms remain unclear. The aim of this study was to i... |
Perturbed DNA methylation by sustained overexpression of Gadd45b induces chromatin disorganization, DNA strand breaks and dopaminergic neurondeath in mice
Ravel-Godreuil, C. et al.
Heterochromatin disorganization is a key hallmark of aging and DNA methylation state is currently the main molecular predictor of chronological age. The most frequent neurodegenerative diseases like Parkinson disease and Alzheimer’s disease are age-related but how the aging process and chromatin alterations ar... |
The Identification of a Novel Fucosidosis-Associated Mutation: A Case of a5-Year-Old Polish Girl with Two Additional Rare Chromosomal Aberrations andAffected DNA Methylation Patterns.
Domin A. et al.
Fucosidosis is a rare neurodegenerative autosomal recessive disorder, which manifests as progressive neurological and psychomotor deterioration, growth retardation, skin and skeletal abnormalities, intellectual disability and coarsening of facial features. It is caused by biallelic mutations in encoding the α-... |
Hepatic transcriptome and DNA methylation patterns following perinataland chronic BPS exposure in male mice.
Brulport A. et al.
BACKGROUND: Bisphenol S (BPS) is a common bisphenol A (BPA) substitute, since BPA is virtually banned worldwide. However, BPS and BPA have both endocrine disrupting properties. Their effects appear mostly in adulthood following perinatal exposures. The objective of the present study was to investigate the impact of ... |
Integrative Analysis of Glucometabolic Traits, Adipose Tissue DNA Methylation and Gene Expression Identifies Epigenetic Regulatory Mechanisms of Insulin Resistance and Obesity in African Americans
Neeraj K. Sharma, Mary E. Comeau, Dennis Montoya, Matteo Pellegrini, Timothy D. Howard, Carl D. Langefeld, Swapan K. Das
Decline in insulin sensitivity due to dysfunction of adipose tissue (AT) is one of the earliest pathogenic events in Type 2 Diabetes. We hypothesize that differential DNA methylation (DNAm) controls insulin sensitivity and obesity by modulating transcript expression in AT. Integrating AT DNAm profiles with transcrip... |
DNA CpG methylation in sequential glioblastoma specimens.
Kraboth, Z and Galik, B and Tompa, M and Kajtar, B and Urban, P andGyenesei, A and Miseta, A and Kalman, B
PURPOSE: Glioblastoma is the most aggressive form of brain tumors. A better understanding of the molecular mechanisms leading to its evolution is essential for the development of treatments more effective than the available modalities. Here, we aim to identify molecular drivers of glioblastoma development and recurr... |
Early Life Exposure to Environmentally Relevant Levels of Endocrine Disruptors Drive Multigenerational and Transgenerational Epigenetic Changes in a Fish Model
Major Kaley M., DeCourten Bethany M., Li Jie, Britton Monica, Settles Matthew L., Mehinto Alvine C., Connon Richard E., Brander Susanne M.
The inland silverside, Menidia beryllina, is a euryhaline fish and a model organism in ecotoxicology. We previously showed that exposure to picomolar (ng/L) levels of endocrine disrupting chemicals (EDCs) can cause a variety of effects in M. beryllina, from changes in gene expression to phenotypic alterations. Here ... |
Chronic cannabidiol alters genome-wide DNA methylation in adult mouse hippocampus: epigenetic implications for psychiatric disease.
Wanner NM, Colwell M, Drown C, Faulk C
Cannabidiol (CBD) is the primary non-psychoactive compound found in cannabis (Cannabis sativa) and an increasingly popular dietary supplement as a result of widespread availability of CBD-containing products. CBD is FDA-approved for the treatment of epilepsy and exhibits anxiolytic, antipsychotic, prosocial, and oth... |
Dnmt3a and Dnmt3b-Decommissioned Fetal Enhancers are Linked to Kidney Disease
Guan Y, Liu H, Ma Z, Li SY, Park J, Sheng X, Susztak K
BACKGROUND: Cytosine methylation is an epigenetic mark that dictates cell fate and response to stimuli. The timing and establishment of methylation logic during kidney development remains unknown. DNA methyltransferase 3a and 3b are the enzymes capable of establishing methylation. METHODS: We generated mice with gen... |
Rheumatoid Arthritis Patients, Both Newly Diagnosed and Methotrexate Treated, Show More DNA Methylation Differences in CD4+ Memory Than in CD4+ Naïve T Cells
Guderud Kari, Sunde Line H., Flåm Siri T., Mæhlen Marthe T., Mjaavatten Maria D., Lillegraven Siri, Aga Anna-Birgitte, Evenrød Ida M., Norli Ellen S., Andreassen Bettina K., Franzenburg Sören, Franke Andre, Haavardsholm Espen A., Rayner Simon, Gervin Kris
Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes pain and swelling of multiple joints in the body. The underlying disease mechanisms are believed to involve a complex interplay between common genetic and environmental factors. The heritability of RA has been estimated to be ~50% for anti-citrull... |

Brulport Axelle, Vaiman Daniel, Chagnon Marie-Christine, Le Corre Ludovic
Environmental pollution is increasingly considered an important factor involved in the obesity incidence. Endocrine disruptors (EDs) are important actors in the concept of DOHaD (Developmental Origins of Health and Disease), where epigenetic mechanisms play crucial roles.

Mitochondrial stress triggers a pro-survival response through epigenetic modifications of nuclear DNA.
Mayorga L, Salassa BN, Marzese DM, Loos MA, Eiroa HD, Lubieniecki F, García Samartino C, Romano PS, Roqué M
Mitochondrial dysfunction represents an important cellular stressor and when intense and persistent cells must unleash an adaptive response to prevent their extinction. Furthermore, mitochondria can induce nuclear transcriptional changes and DNA methylation can modulate cellular responses to stress. We hypothesized ... |
