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 ...

Pathophysiological adaptations of resistance arteries in rat offspringexposed in utero to maternal obesity is associated with sex-specificepigenetic alterations.

BACKGROUND/OBJECTIVES: Maternal obesity impacts vascular functions linked to metabolic disorders in offspring, leading to cardiovascular diseases during adulthood. Even if the relation between prenatal conditioning of cardiovascular diseases by maternal obesity and vascular function begins to be documented, little i...

Muscle allele-specific expression QTLs may affect meat quality traitsin Bos indicus.
Bruscadin J.J. et al.
Single nucleotide polymorphisms (SNPs) located in transcript sequences showing allele-specific expression (ASE SNPs) were previously identified in the Longissimus thoracis muscle of a Nelore (Bos indicus) population consisting of 190 steers. Given that the allele-specific expression pattern may result from cis-regul...

IGFBP2 protects against pulmonary fibrosis through inhibiting P21-mediated senescence
Chiahsuan, C. et al.
Accumulation of senescent cells contributes to age related diseases including idiopathic pulmonary fibrosis (IPF). Insulin-like growth factor binding proteins (IGFBPs) are evolutionarily conserved proteins that play a vital role in many biological processes. Overall, little is known about the functions of IGFBP2 in ...

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.

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...
