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.

Spatiotemporal dynamics of Aurora B-PLK1-MCAK signaling axis orchestrates kinetochore bi-orientation and faithful chromosome segregation

Scientific Reports, 2015
Chromosome segregation in mitosis is orchestrated by the dynamic interactions between the kinetochore and spindle microtubules. The microtubule depolymerase mitotic centromere-associated kinesin (MCAK) is a key regulator for an accurate kinetochore ...

Disrupting Lipid Raft Microdomains to Block Polyploid Giant Cancer Cell Budding and Enhance Radiotherapy Response

Advanced Science, EarlyView.
Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...

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 ...

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Mouse oocytes depend on BubR1 for proper chromosome segregation but not for prophase I arrest

Nature Communications, 2015
Mammalian female meiosis is error prone, with rates of meiotic chromosome missegregations strongly increasing towards the end of the reproductive lifespan.

Chromosome Segregation: Correcting Improper Attachment [PDF]

Current Biology, 2004
Accurate chromosome segregation requires that the two sister kinetochores attach to microtubules from opposite spindle poles. New work reveals how a kinetochore can segregate properly while remaining improperly attached to two spindle poles.

Autosomal Dominant Erythrocytosis Caused by Non‐Renal Erythropoietin (EPO) Due to EPO c.‐136 G>A Germline Mutation

American Journal of Hematology, EarlyView.
A novel erythropoietin (EPO) promoter mutation (c.‐136 G>A) causes autosomal dominant erythrocytosis via non‐renal expression of EPO. ABSTRACT We previously reported a five‐generation kindred with autosomal dominant erythrocytosis associated with a novel germline promoter variant in the erythropoietin (EPO) gene (EPO c.‐136 G>A).

Nance‐Horan Syndrome: Further Delineation of the Affected Male and the Female Carrier Phenotypes

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nance‐Horan syndrome (NHS; OMIM 302350) is a rare, X‐linked syndrome characterized by bilateral congenital cataracts leading to profound vision loss, specific dental anomalies including characteristic screwdriver blade‐shaped incisors, facial anomalies, and intellectual disability.
