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 ...

Cryo-ET comparison of the hierarchical ultrastructure of silkworm, spider, and artificial silk fibers

open access: yesNature Communications
Spider and silkworm silks are renowned for their exceptional mechanical properties, which arises from their ultrastructural organization. However, this architecture remains incompletely understood.

rDNA Clusters Make Contact with Genes that Are Involved in Differentiation and Cancer and Change Contacts after Heat Shock Treatment

open access: yesCells, 2019
Human rDNA clusters form numerous contacts with different chromosomal regions as evidenced by chromosome conformation capture data. Heterochromatization of rDNA genes leads to heterochromatization in different chromosomal regions coupled with the ...

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

The Epigenetics Dilemma [PDF]

open access: yesGenes, 2019
This special issue of Genes demonstrates clearly that research in epigenetics has proceeded at a very rapid pace in the last decade [...]

The promise of epigenetic editing strategies in functionally curing chronic hepatitis B virus infections

open access: yesEpigenetics Communications
Chronic hepatitis B (CHB) is a major global health issue that remains without a cure due to the persistence of covalently closed circular DNA (cccDNA) and integrated DNA (intDNA) in hepatitis B virus (HBV) infected hepatocytes.

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.

Inverse relationship between genetic diversity and epigenetic complexity [PDF]

open access: yes, 2008
Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutral Theory’, which however remains an ...

scIVNL-seq resolves in vivo single-cell RNA dynamics of immune cells during Salmonella infection

open access: yesNature Communications
The immune response against pathogens involves multiple cell state transitions and complex gene expression changes. Here, we establish a single-cell in vivo new RNA labeling sequencing method (scIVNL-seq) and apply it to survey time-resolved RNA dynamics

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
