Histone modifications within the human X centromere region. [PDF]
PLoS ONE, 2009 Human centromeres are multi-megabase regions of highly ordered arrays of alpha satellite DNA that are separated from chromosome arms by unordered alpha satellite monomers and other repetitive elements.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

DNA Environment of Centromeres and Non-Homologous Chromosomes Interactions in Mouse
Cells, 2021 Although the pericentromeric regions of chromosomes that are enriched in tandemly repeated satellite DNA represent a significant part of eukaryotic genomes, they remain understudied, which is mainly due to interdisciplinary knowledge gaps. Recent studies

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Chromosomal Differentiation of Deschampsia (Poaceae) Based on Four Satellite DNA Families
Frontiers in Genetics, 2021 Diverse families of satellite DNA (satDNA) were detected in heterochromatin regions of Deschampsia. This kind of repetitive DNA consists of tandem repeat sequences forming big arrays in genomes, and can contribute to lineages differentiation.

Nudeotide sequence of mouse satellite DNA [PDF]
Nucleic Acids Research, 1981 The nucleotide sequence of uncloned mouse satellite DNA has been determined by analyzing Sau96I restriction fragments that correspond to the repeat unit of the satellite DNA. An unambiguous sequence of 234 bp has been obtained. The sequence of the first 250 bases from dimeric satellite fragments present in Sau96I limit digests corresponds almost ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Satellite DNA Modulates Gene Expression in the Beetle Tribolium castaneum after Heat Stress. [PDF]
PLoS Genetics, 2015 Non-coding repetitive DNAs have been proposed to perform a gene regulatory role, however for tandemly repeated satellite DNA no such role was defined until now.

Protective role of γ ⁃ tocotrienol on muscle satellite cells of Duchenne muscular dystrophy in mice
Chinese Journal of Contemporary Neurology and Neurosurgery, 2022 Objective To investigate the damage of skeletal muscle satellite cells in Duchenne muscular dystrophy (DMD) and the protective effect of γ⁃tocotrienol (GT3) on muscle satellite cells in DMD knockout mice.

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
