The Social Brain Meets the Reactive Genome: Neuroscience, Epigenetics and the New Social Biology

open access: yesFrontiers in Human Neuroscience, 2014
The rise of molecular epigenetics over the last few years promises to bring the discourse about the sociality and susceptibility to environmental influences of the brain to an entirely new level.

The danger of epigenetics misconceptions (epigenetics and stuff…) [PDF]

open access: yesBiochemistry and Cell Biology, 2015
Within the past two decades, the fields of chromatin structure and function and transcription regulation research started to fuse and overlap, as evidence mounted to support a very strong regulatory role in gene expression that was associated with histone post-translational modifications, DNA methylation, as well as various chromatin-associated ...

Epigenetics and Evolution [PDF]

open access: yesIntegrative and Comparative Biology, 2014
Epigenetic mechanisms traditionally have been studied in the domains of development and disease, but they may also play important roles in ecological and evolutionary processes. In this article, we revisit historical as well as recent studies that indicate significant impacts of epigenetic processes on evolution.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Complete loss of H3K9 methylation dissolves mouse heterochromatin organization

open access: yesNature Communications, 2021
Histone H3K9 methylation (H3K9me) states define repressed chromatin in eukaryotic cells. Here the authors reveal complete loss of all H3K9me in mammalian cells through successive deletion of H3K9 methyltransferase genes that results in the dissolution of

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

A DNMT3A PWWP mutation leads to methylation of bivalent chromatin and growth retardation in mice

open access: yesNature Communications, 2019
PWWP domains of DNMT3A and DNMT3B are proposed to interact with H3K36me3. Here the authors present a mouse model carrying a D329A point mutation in the DNMT3A PWWP domain and find this causes dominant postnatal growth retardation, with aberrant ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Molecular epigenetics in the management of ovarian cancer: Are we investigating a rational clinical promise?

open access: yesFrontiers in Oncology, 2014
Epigenetics is essentially a phenotypical change in gene expression without any alteration of the DNA sequence; the emergence of epigenetics in cancer research and mainstream oncology is fueling new hope.
