Epigenetic modifier alpha-ketoglutarate modulates aberrant gene bodymethylation and hydroxymethylation marks in diabetic heart.
Published: April, 2023

Abstract: BACKGROUND: Diabetic cardiomyopathy (DCM) is a leading cause of death in diabetic patients. Hyperglycemic myocardial microenvironment significantly alters chromatin architecture and the transcriptome, resulting in aberrant activation of signaling ...

Methylation and expression of glucocorticoid receptor exon-1 variants andFKBP5 in teenage suicide-completers.
Published: February, 2023

Abstract: A dysregulated hypothalamic-pituitary-adrenal (HPA) axis has repeatedly been demonstrated to play a fundamental role in psychiatric disorders and suicide, yet the mechanisms underlying this dysregulation are not clear. Decreased expression of the ...

Gene body DNA hydroxymethylation restricts the magnitude oftranscriptional changes during aging.
Published: February, 2023

Abstract: DNA hydroxymethylation (5hmC) is the most abundant oxidative derivative of DNA methylation (5mC) and is typically enriched at enhancers and gene bodies of transcriptionally active and tissue-specific genes. Although aberrant genomic 5hmC has been ...

Neonatal inflammation increases hippocampal KCC2 expression throughmethylation-mediated TGF-β1 downregulation leading to impairedhippocampal cognitive function and synaptic plasticity in adult mice.
Published: January, 2023

Abstract: The mechanisms by which neonatal inflammation leads to cognitive deficits in adulthood remain poorly understood. Inhibitory GABAergic synaptic transmission plays a vital role in controlling learning, memory and synaptic plasticity. Since early-lif...

The age of bone marrow dictates the clonality of smooth muscle-derivedcells in atherosclerotic plaques.
Published: January, 2023

Abstract: Aging is the predominant risk factor for atherosclerosis, the leading cause of death. Rare smooth muscle cell (SMC) progenitors clonally expand giving rise to up to ~70\% of atherosclerotic plaque cells; however, the effect of age on SMC clonality...

Spurious transcription causing innate immune responses is prevented by5-hydroxymethylcytosine.
Published: December, 2022

Abstract: Generation of functional transcripts requires transcriptional initiation at regular start sites, avoiding production of aberrant and potentially hazardous aberrant RNAs. The mechanisms maintaining transcriptional fidelity and the impact of spuriou...

Developmental and Injury-induced Changes in DNA Methylation inRegenerative versus Non-regenerative Regions of the VertebrateCentral Nervous System
Published: January, 2022

Abstract: Background Because some of its CNS neurons (e.g., retinal ganglion cells after optic nerve crush (ONC)) regenerate axons throughout life, whereas others (e.g., hindbrain neurons after spinal cord injury (SCI)) lose this capacity as tadpoles metamo...

Epigenetic remodelling of enhancers in response to estrogen deprivationand re-stimulation.
Published: September, 2021

Abstract: Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investig...

Genome-wide 5-hydroxymethylcytosine (5hmC) emerges at early stage ofdifferentiation of a putative hepatocyte progenitor
Published: May, 2020

Abstract: A basic question linked to differential patterns of gene expression is how cells reach different fates despite using the same DNA template. Since 5-hydroxymethylcytosine (5hmC) emerged as an intermediate metabolite in active DNA demethylation, the...
