Centromere DNA Dynamics: Latent Centromeres and Neocentromere Formation [PDF]
The American Journal of Human Genetics, 1997 The centromere is a vital chromosomal structure that provides all living cells with the ability to faithfully partition their genetic material during mitotic and meiotic cell divisions. It functions by holding newly replicated sister chromatids together, allowing the attachment of spindle microtubules, and orchestrating the ordered movement of ...

Cytometry Part A, EarlyView.ABSTRACT Myelofibrosis is a myeloproliferative neoplasm with potential to transform to acute myeloid leukemia. This evolution is unpredictable and current assays lack the sensitivity and applicability needed to predict this transformation. While population‐level data utilizing comprehensive genomic profiling can identify subgroups at higher risk of ...

Grassland Research, EarlyView.From structure to application: evolutionary insights and genome editing strategies for CENH3‐mediated haploid induction in legumes. Abstract Background The centromeric histone variant CENH3 is crucial for chromosome segregation and haploid induction in plants, yet its evolutionary patterns in legumes remain poorly characterized. Methods We investigated

PBRM1 directs PBAF to pericentromeres and protects centromere integrity
Nature CommunicationsThe specialised structure of the centromere is critical for effective chromosome segregation, but its repetitive nature makes it vulnerable to rearrangements.

JEADV Clinical Practice, EarlyView.ABSTRACT Multiple myeloma (MM) is a malignant plasma cell disorder that primarily presents with CRAB symptoms (calcium elevation, renal failure, anemia, and bone abnormalities). In rare cases, MM manifests with systemic complications like skin ulcers, which present management challenges. Here, we report a 78‐year‐old Japanese man with MM and refractory

Reconstruction of the kinetochore: a prelude to meiosis
Cell Division, 2007 In eukaryotic organisms, chromosomes are spatially organized within the nucleus. Such nuclear architecture provides a physical framework for the genetic activities of chromosomes, and changes its functional organization as the cell moves through the ...

A Framework for Bioinformatic Reporting in Prenatal Sequencing: Insights From a Systematic Review
Prenatal Diagnosis, EarlyView.ABSTRACT Genomic sequencing has become a key tool in the investigation of foetal anomalies, with a growing shift from targeted panels to exome and genome sequencing. These broader approaches generate significantly more data, underscoring the need for robust bioinformatics pipelines. However, practices vary widely between laboratories.

G3: Genes, Genomes, Genetics, 2018 Crossover recombination during meiosis is accompanied by a dramatic chromosome reorganization. In Saccharomyces cerevisiae, the onset of meiotic recombination by the Spo11 transesterase leads to stable pairwise associations between previously ...
