Proteogenomic Characterization Reveals Subtype‐Specific Therapeutic Potential for HER2‐Low Breast Cancer

Advanced Science, EarlyView.
Multiomic profiling of HER2‐low breast cancer identifies three proteomic subtypes with distinct therapeutic strategies: endocrine, antiangiogenic, and anti‐HER2 therapies. Genomic and lactate modification landscapes are detailed, providing insights for precise management.

Axial contraction and short-range compaction of chromatin synergistically promote mitotic chromosome condensation

eLife, 2015
The segregation of eukaryotic chromosomes during mitosis requires their extensive folding into units of manageable size for the mitotic spindle. Here, we report on how phosphorylation at serine 10 of histone H3 (H3 S10) contributes to this process. Using

NUSAP1 Recruits DAXX to Suppress HIF‐Driven Triple‐Negative Breast Cancer Progression

Advanced Science, EarlyView.
A double‐negative feedback loop is identified in TNBC where NUSAP1 bridges HIF and DAXX via its microtubule‐associated domain (MAD) to recruit SETDB1, repressing HIF transcriptional activity by depositing the H3K9me3 repressive mark on HIF target genes, while HIF itself suppresses NUSAP1.

Histone Marks Direct Chromosome Segregation [PDF]

Cell, 2015
Germline stem cells divide asymmetrically, producing a self-renewing stem cell and a differentiating progenitor. Xie et al. now show that this depends on two asymmetric events that together partition a genome copy, carrying the old histones to the stem cell daughter and a copy with new, unmarked histones to the differentiating daughter.

Structural Variation and 3D Genome‐Driven DNA/RNA Methylation Divergence Contributing to Cotton Fiber Domestication

Advanced Science, EarlyView.
These findings elucidated the crucial role of the “SVs‐3D genome remodeling‐epigenetic modifications‐gene expression” cascade regulatory network in cotton fiber domestication, offering both a theoretical foundation and genetic resources for molecular design breeding in fiber crops.

Coupling chromosome organization to genome segregation in Archaea

Nature Communications
Chromosome segregation is a fundamental process in all life forms and requires coordination with genome organization, replication and cell division. The mechanism that mediates chromosome segregation in archaea remains enigmatic.

Integrative Omics Defines Metabolic Biomarkers and Genetic Regulatory Mechanisms of Mortality Risk

Advanced Science, EarlyView.
Understanding mortality mechanisms remains a fundamental challenge. Through multi‐omics analysis of a three‐generation chicken model, are identified 45,585 mQTLs and establish a 16‐metabolite predictor of mortality. An inflammation‐growth trade‐off and evolutionarily conserved pathways involving butyrate–microbiota interactions and L‐cysteine's dual ...

Spindle mechanics and chromosome segregation

Molecular Biology of the Cell, 2019
The Minisymposium “Spindle Mechanics and Chromosome Segregation” featured new and exciting findings related to the spindle and chromosomes during mitosis and meiosis. It covered a range of topics including spindle architecture and mechanics, kinetochore–microtubule interactions, chromosome dynamics at mitotic entry and exit, as well as mitotic errors ...

Genome‐Wide Association Analyses Reveal the Genetic Basis of EMS Mutagenesis Efficiency in Rice

Advanced Science, EarlyView.
Based on large‐scale screening of 420 rice accessions, GWAS identified the Rc locus as a key regulator of EMS mutagenesis efficiency. Functional Rc alleles enhance both seed survival and genome‐wide mutation frequency by boosting antioxidant enzyme activities (CAT, SOD, POD) and reducing oxidative damage.
