Epigenetic Regulation in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
The aim of this narrative literature review was to identify epigenetic marks associated with periodontitis and to place them in a biological context. The literature was reviewed based on pre‐defined criteria. Cell type specific chromatin and mRNA modifications were included.

CpGcluster: a distance-based algorithm for CpG-island detection

BMC Bioinformatics, 2006
Background Despite their involvement in the regulation of gene expression and their importance as genomic markers for promoter prediction, no objective standard exists for defining CpG islands (CGIs), since all current approaches rely on a large ...

Dnmt3b ablation impairs fracture repair through upregulation of Notch pathway [PDF]

, 2020
We previously established that DNA methyltransferase 3b (Dnmt3b) is the sole Dnmt responsive to fracture repair and that Dnmt3b expression is induced in progenitor cells during fracture repair.

Effects of Electroacupuncture at ST36 on Visceral Pain and Inflammatory Markers in IBS Rats

Neurogastroenterology &Motility, EarlyView.
Electroacupuncture (EA) at ST36 significantly reduced visceral pain and colonic inflammation in IBS model rats. EA increased pain thresholds, lowered AWR scores, and downregulated key inflammatory mediators (IL‐1β, IL‐6, TNF‐α, TRPV1, NF‐κB). These findings highlight ST36‐targeted EA as a promising therapeutic strategy for IBS visceral hypersensitivity

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this

Analysis of CpG methylation sites and CGI among human papillomavirus DNA genomes

BMC Genomics, 2011
Background The Human Papillomavirus (HPV) genome is divided into early and late coding sequences, including 8 open reading frames (ORFs) and a regulatory region (LCR).

Characterization of DNA methylation as a function of biological complexity via dinucleotide inter-distances

, 2015
We perform a statistical study of the distances between successive occurrencies of a given dinucleotide in the DNA sequence for a number of organisms of different complexity.

Identification of Crucial Drug Targets and Pathways to Reprogram Drug Resistance Through Epigenetic Modulation in Advanced Lung Cancer Using Integrated Bioinformatics Approach

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Resistance to chemotherapy, which is demonstrated in almost every patient with advanced‐stage lung cancer (ALC), underscores an urgent need to unravel the underlying molecular mechanisms and identify novel strategies to overcome drug resistance. In the present study, an attempt was made to identify epigenetic targets and modulators that can be

CpG Islands and Double-Minute Chromosomes

Genomics, 1998
Double-minute chromosomes (DMs) amplify oncogenes in human tumors. The organization of genomic DNA in four independently isolated DMs amplifying the DHFR (dihydrofolate reductase) gene has been compared by mapping locations of CpG islands. When cleaved with methylation-sensitive rare-cutting restriction endonucleases, three hypomethylated GC-rich DNA ...
