Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire

PROTEOMICS, EarlyView.
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

Epigenetic gene expression links heart failure to memory impairment

EMBO Molecular Medicine, 2021
In current clinical practice, care of diseased patients is often restricted to separated disciplines. However, such an organ‐centered approach is not always suitable.

Theoretical analysis of the role of chromatin interactions in long-range action of enhancers and insulators [PDF]

, 2011
Long-distance regulatory interactions between enhancers and their target genes are commonplace in higher eukaryotes. Interposed boundaries or insulators are able to block these long distance regulatory interactions. The mechanistic basis for insulator activity and how it relates to enhancer action-at-a-distance remains unclear. Here we explore the idea

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

Small, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

Biphasic euchromatin-to-heterochromatin transition on the KSHV genome following de novo infection. [PDF]

PLoS Pathogens, 2013
The establishment of latency is an essential step for the life-long persistent infection and pathogenesis of Kaposi's sarcoma-associated herpesvirus (KSHV).

RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection

Molecular Ecology Resources, EarlyView.
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

Peptide AEDL alters chromatin conformation via histone binding

AIMS Biophysics, 2020
Eukaryotic DNA is tightly packed into chromatin, a DNA–protein structure that exists as transcriptionally permissive euchromatin or repressive heterochromatin. Post-translational modification of histones plays a key role in regulating chromatin dynamics.

Inactivation of Histone Chaperone HIRA Unmasks a Link Between Normal Embryonic Development of Melanoblasts and Maintenance of Adult Melanocyte Stem Cells

Aging Cell, EarlyView.
Expression of HIRA in embryonic melanoblasts is required for proper epigenetic programing and lineage differentiation. Although HIRA deficiency results in a mild phenotype at birth and young adulthood, the melanocytic lineage is sensitive to proliferative challenge, prone to loss of stem cells and dramatically accelerated hair greying in later life ...

Pathogenic variants in chromatin‐related genes: Linking immune dysregulation to neuroregression and acute neuropsychiatric disorders

Developmental Medicine &Child Neurology, EarlyView.
Chromatin machinery influences how DNA is ‘wrapped’ around histones in the nucleosome of immune and brain cells. Plain language summary: https://onlinelibrary.wiley.com/doi/10.1111/dmcn.16299 Abstract We report eight children with de novo pathogenic DNA variants in chromatin‐related genes: MORC2, CHD7, KANSL1, KMT2D, ZMYND11, HIST1HIE, EP300, and KMT2B.

Polymer Modelling Predicts Chromosome Reorganisation in Senescence [PDF]

Cell Reports 28, 3212 (2019), 2020
Lamina-associated domains (LADs) cover a large part of the human genome and are thought to play a major role in shaping the nuclear architectural landscape. Here, we perform polymer simulations, microscopy and mass spectrometry to dissect the roles played by heterochromatin- and lamina-mediated interactions in nuclear organisation.
