TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

open access: yesAdvanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

Tissue Architecture Is Required for Chromosome Segregation Fidelity in Epithelia

open access: yes, 2018
Chromosome segregation is classically viewed as a cell-intrinsic process. We tested this assumption by comparing chromosome segregation fidelity in various epithelial cells in their native tissue and as dissociated cells in culture and discovered that ...

Fission yeast neddylation ligase Dcn1 facilitates cohesin cleavage and chromosome segregation at anaphase

open access: yesBiology Open, 2017
Post-translational protein modification such as phosphorylation and ubiquitination are critical during mitosis to ensure proper timing and progression of chromosome segregation.

SUV39H1 orchestrates temporal dynamics of centromeric methylation essential for faithful chromosome segregation in mitosis

open access: yes, 2012
Histone methylation performs multiple functions such as DNA replication, transcription regulation, heterochromatin formation, and chromatin condensation. How this methylation gradient is orchestrated in the centromere during chromosome segregation is not

Nrsn1–Smarcc1 Coupling Regulates Neural Stem Cell Differentiation and Chronic‐phase Recovery After Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
In the post‐stroke brain, Foxa2 induces the transcriptional upregulation of Nrsn1 in NSCs. Nrsn1 functionally couples with Smarcc1, modulating its nuclear availability and protein abundance, thereby influencing Smarcc1‐associated regulatory programs linked to neuronal lineage commitment. Through this coupling, Nrsn1 promotes the differentiation of NSCs

Progressive chromosome shape changes during cell divisions

open access: yesEMBO Reports
Mitotic chromosomes give genome portions the required compaction and mechanical stability for faithful inheritance during cell divisions. They are shaped by the chromosomal condensin complex.

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

open access: yesAdvanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Cell-Cycle Kinases Coordinate the Resolution of Recombination Intermediates with Chromosome Segregation

open access: yesCell Reports, 2013
Homologous recombination leads to the formation of DNA joint molecules (JMs) that must be resolved to allow chromosome segregation, but how resolution is temporally coupled with chromosome segregation is unknown.

Glucocorticoid Receptor Signaling in Myeloid Cells Orchestrates Inflammation Resolution and Muscle Repair

open access: yesAdvanced Science, EarlyView.
Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...

A Cohesin-Based Partitioning Mechanism Revealed upon Transcriptional Inactivation of Centromere.

open access: yesPLoS Genetics, 2016
Transcriptional inactivation of the budding yeast centromere has been a widely used tool in studies of chromosome segregation and aneuploidy. In haploid cells when an essential chromosome contains a single conditionally inactivated centromere (GAL-CEN ...
