Evidence for conserved DNA and histone H3 methylation reprogramming in mouse, bovine and rabbit zygotes

open access: yesEpigenetics & Chromatin, 2008
Background In mammals the parental genomes are epigenetically reprogrammed after fertilization. This reprogramming includes a rapid demethylation of the paternal (sperm-derived) chromosomes prior to DNA replication in zygotes.

No evidence for AID/MBD4-coupled DNA demethylation in zebrafish embryos. [PDF]

open access: yesPLoS ONE, 2014
The mechanisms responsible for active DNA demethylation remain elusive in Metazoa. A previous study that utilized zebrafish embryos provided a potent mechanism for active demethylation in which three proteins, AID, MBD4, and GADD45 are involved.

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

open access: yesAdvanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Tet inactivation disrupts YY1 binding and long-range chromatin interactions during embryonic heart development

open access: yesNature Communications, 2019
Tet-mediated DNA demethylation is intimately involved in reguatling embryonic development. Here the authors characterise DNA methylation and hydroxymethylation dynamics during early cardiac development in both human and mice and provide evidence that Tet-

NF-kappaB mediates Gadd45beta expression and DNA demethylation in the hippocampus during fear memory formation.

open access: yesFrontiers in Molecular Neuroscience, 2015
Gadd45-mediated DNA demethylation mechanisms have been implicated in the process of memory formation. However, the transcriptional mechanisms involved in the regulation of Gadd45 gene expression during memory formation remain unexplored.

Active DNA demethylation in human postmitotic cells correlates with activating histone modifications, but not transcription levels [PDF]

open access: yes, 2010
Background: In mammals, the dynamics of DNA methylation, in particular the regulated, active removal of cytosine methylation, has remained a mystery, partly due to the lack of appropriate model systems to study DNA demethylation.

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

Gender Differences in Global but Not Targeted Demethylation in iPSC Reprogramming

open access: yesCell Reports, 2017
Global DNA demethylation is an integral part of reprogramming processes in vivo and in vitro, but whether it occurs in the derivation of induced pluripotent stem cells (iPSCs) is not known.

Epigenetic and antitumor effects of platinum(IV)-octanoato conjugates [PDF]

open access: yes, 2017
We present the anticancer properties of cis, cis, trans-[Pt(IV)(NH3)2Cl2(OA)2] [Pt(IV)diOA] (OA = octanoato), Pt(IV) derivative of cisplatin containing two OA units appended to the axial positions of a six-coordinate Pt(IV) center.
