Transcriptional Scaffolds for Heterochromatin Assembly

, 2009
Heterochromatin is dynamically regulated during the cell cycle and in response to developmental signals. Recent findings from diverse systems suggest an extensive role for transcription in the assembly of heterochromatin, highlighting the emerging theme ...

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome

The FEBS Journal, EarlyView.
Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

The epigenetic landscape of skeletal muscle in response to exercise and aging

The FEBS Journal, EarlyView.
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.

Nuclear positioning and functional regulation of endogenous genes and transgenes in the fruit fly Drosophila melanogaster and in mammalian cells

, 2006
The goal of the work was to address the role of higher order nuclear architecture in the functional regulation of endogenous genes and transgenes in different species.

Heterochromatin: RNA Points the Way

, 2004
Mutation of the multi-KH domain protein DPP1, which has single-stranded nucleic acid binding activity, suppresses heterochromatin-mediated silencing in Drosophila; it also disrupts the modification of histone H3 at lysine 9, and association of ...

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

The FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.

Reorganization of H3K9me heterochromatin leads to neuronal impairment via the cascading destruction of the KDM3B-centered epigenomic network

iScience
Summary: Histone H3K9 methylated heterochromatin silences repetitive non-coding sequences and lineage-specific genes during development, but how tissue-specific genes escape from heterochromatin in differentiated cells is unclear.

Constitution and function of intergenic genome regions in cultivated versus annual wild soybean in China

Journal of Integrative Plant Biology, EarlyView.
Three‐case restricted two‐stage multi‐locus multi‐allele genome‐wide association study identified main‐effect genes and detected the regulatory effects of intergenic loci on genes, enabling comprehensive dissection of the genic‐intergenic genetic system for quantitative traits and providing a strategy for studying their genetic basis.

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

Journal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...
