Alpha-satellite RNA transcripts are repressed by centromere–nucleolus associations

eLife, 2020
Although originally thought to be silent chromosomal regions, centromeres are instead actively transcribed. However, the behavior and contributions of centromere-derived RNAs have remained unclear.

PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

Advanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

Temporal characterization of homology-independent centromere coupling in meiotic prophase.

PLoS ONE, 2010
BackgroundOver the past thirty years several reports of the pairing or association of non-homologous centromeres during meiotic prophase have appeared in the literature.

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis

Advanced Science, EarlyView.
A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.

Calcineurin‐Dependent Stress Adaptation Enables Caspofungin Heteroresistance Leading to Stable Resistance in Candida Glabrata

Advanced Science, EarlyView.
Caspofungin heteroresistance is prevalent in clinical Candida glabrata isolates and depends on calcineurin‐mediated stress adaptation. This transient phenotype serves as a reservoir for resistance evolution, enabling the emergence of stable resistant descendants under prolonged drug pressure.

TET1 Inhibition Promotes Therapeutic Sensitivity in TP53‐Mutant GBM by Influencing Genome Fragility and Altering TAMs Biology

Advanced Science, EarlyView.
In TP53mut GBM cells, reduced P53 function is associated with increased TET1 expression. Genetic or pharmacological inhibition of TET1 correlates with genome fragility, including DNA damage, cellular senescence, telomere shortening, and reactive oxygen species accumulation, which may contribute to increased efficacy of antitumor therapy.

Anti-centromere antibody positivity with coexisting idiopathic portal hypertension and primary biliary cholangitis progressing to limited cutaneous systemic sclerosis: a case report

Journal of Medical Case Reports
Background Anti-centromere antibodies are autoantibodies that selectively bind to the centromere region of chromosomes. Studies have indicated that anti-centromere antibodies can induce microvascular alterations and tissue remodeling, ultimately leading ...

Neocentromeres Provide Chromosome Segregation Accuracy and Centromere Clustering to Multiple Loci along a Candida albicans Chromosome. [PDF]

PLoS Genetics, 2016
Assembly of kinetochore complexes, involving greater than one hundred proteins, is essential for chromosome segregation and genome stability. Neocentromeres, or new centromeres, occur when kinetochores assemble de novo, at DNA loci not previously ...
