Quiescence induces epigenetic changes in bovine fibroblasts and improves their reprogramming into cloned embryos [PDF]
, 2013 Cloning by somatic cell nuclear transfer (SCNT) forces cells to lose their lineage-specific epigenetic marks and become totipotent again. This reprogramming process often results in epigenetic and transcriptional aberrations that compromise development ...

NICE: A Two‐Step Non‐Invasive Framework for Embryo cfDNA Read Enrichment and Quality Assessment
Advanced Science, EarlyView.The non‐invasive NICE framework, built on an ensemble stacking machine learning model, prioritizes embryos by analyzing cell‐free DNA from spent culture medium. By integrating multimodal signals, including genomic and epigenetic profiles, this automated approach standardizes morphological assessment without human bias, paving the way for more precise ...

Monoubiquitination of Histone H2B Blocks Eviction of Histone Variant H2A.Z from Inducible Enhancers
, 2016 Covalent modifications of histones play a crucial role in the regulation of gene expression. Histone H2B monoubiquitination has mainly been described as a regulator of transcription elongation, but its role in transcription initiation is poorly ...

Advanced Science, EarlyView.Radiation triggers glycolytic reprogramming in alveolar epithelial type II cells, causing pathological lactate accumulation. This metabolic stress drives p300‐mediated H3K18 lactylation at the VIRMA promoter, activating transcription. Elevated VIRMA enriches m6A on GATA3 mRNA, which YTHDF1 stabilizes, ultimately driving epithelial–mesenchymal ...

Advanced Science, EarlyView.Proposed model of CHST1‐associated immune remodeling in triple‐negative breast cancer. In CHST1‐low tumors, greater nuclear accumulation of NKRF is associated with repression of an NF‐κB‐related CCL20 transcriptional program and an immune‐inflamed microenvironment.

Advanced Science, EarlyView.In this study, we identify a novel functional role of ZBTB18 in regulating trigeminal‐mediated neuropathic pain. Nerve injury reduces ZBTB18 in trigeminal ganglion neurons, impairing CHD4/NuRD recruitment and de‐repressing Clic1. Elevated CLIC1 enhances chloride channel activity and neuronal hyperexcitability, thereby driving pain.

Advanced Science, EarlyView.In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Single-molecule analysis reveals the mechanism of chromatin ubiquitylation by variant PRC1 complexes
Chromatin regulation relies on “writer” enzymes that add posttranslational modifications to histone proteins. Variant polycomb repressive complex 1 (PRC1) exists as several subtypes, which are “writers” of ubiquitylation on histone H2A K118 and K119 ...

Advanced Science, EarlyView.Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.
