Centromere mechanical maturation during mammalian cell mitosis

Nature Communications, 2019
During mitosis, tension at the centromere occurs from the spindle but the role of centromere mechanics in controlling metaphase tension is poorly understood.

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

Advanced Science, EarlyView.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

The Crosstalk Between CRL5 and APC/C E3 Ligases Regulates Metastasis and Chemosensitivity of Cancer Cells

Advanced Science, EarlyView.
This study uncovers a previously unknown crosstalk between two major ubiquitin ligases, CRL5 and APC/C. The authors identify APC11 as a binding partner of CUL5, showing that their interaction regulates neddylation, substrate stability, and mitotic progression.

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.

Sister centromere fusion during meiosis I depends on maintaining cohesins and destabilizing microtubule attachments.

PLoS Genetics, 2019
Sister centromere fusion is a process unique to meiosis that promotes co-orientation of the sister kinetochores, ensuring they attach to microtubules from the same pole during metaphase I.

“Point” Centromeres of Saccharomyces Harbor Single Centromere-Specific Nucleosomes [PDF]

Genetics, 2012
Abstract The “point” centromere of budding yeast is genetically defined by an ∼125-bp sequence. Recent fluorescence measurements of kinetochore clusters have suggested that this sequence specifies multiple centromere histone 3 (CenH3) nucleosomes.

EGR Proteins Mediate Interferon‐Independent Anti‐HSV‐1 Responses Through Viral and Host Targets

Advanced Science, EarlyView.
Early antiviral responses are typically mediated by interferons. However, during HSV‐1 infection, host early growth response (Egr) genes, which are not interferon‐stimulated genes, are quickly induced by viral protein ICP0. EGR proteins, in turn, suppress viral lytic infection by activating viral latency‐associated (LAT) and host immune regulatory ...

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, EarlyView.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...

SEQUENCE OF CENTROMERE SEPARATION: ROLE OF CENTROMERIC HETEROCHROMATIN [PDF]

Genetics, 1982
ABSTRACT The late metaphase-early anaphase cells from various tissues of male Mus musculus, M. poschiavinus, M. spretus, M. castaneus, female and male Bos taurus (cattle) and female Myopus schisticolor (wood lemming) were analyzed for centromeres that showed separation into two daughter centromeres and those that did not show such ...
