Nuclear Envelope Breakdown: Actin’ Quick to Tear Down the Wall
نویسندگان
چکیده
Nuclear envelope breakdown in metazoan cells is thought to be facilitated by microtubules, which pull on the nuclear membranes. Unexpectedly, an F-actin meshwork helps to tear down the large nucleus of starfish oocytes and to prevent chromosome loss in meiosis.

Actin-myosin tears it up
Actin-myosin tears it up aspase cleavage of nuclear lamin proteins was thought to be sufficient to cause disintegration of the nucleus during apoptosis. Now, Croft et al. (page 245) show that the actin-myosin cytoskeleton generates a pulling force required to tear apart the structure. When studying the role of actin and myosin in plasma membrane blebbing and cell contraction during apoptosis, t...
متن کاملAn Arp2/3 Nucleated F-Actin Shell Fragments Nuclear Membranes at Nuclear Envelope Breakdown in Starfish Oocytes
Animal cells disassemble and reassemble their nuclear envelopes (NEs) upon each division. Nuclear envelope breakdown (NEBD) serves as a major regulatory mechanism by which mixing of cytoplasmic and nuclear compartments drives the complete reorganization of cellular architecture, committing the cell for division. Breakdown is initiated by phosphorylation-driven partial disassembly of the nuclear...
متن کاملCharacterization of novel F-actin envelopes surrounding nuclei during cleavage of a polychaete worm.
F-actin accumulations and their possible functions were investigated during cleavage of the polychaete Ophryotrocha puerilis. Unusual cytoplasmic accumulations of F-actin were detected which have never been described before in animal embryos. As shown by TRITC-phalloidin labeling, envelopes of F-actin surrounded late prophase nuclei for a short period of time. DTAF-immunofluorescence of beta-tu...
متن کاملChromosome segregation during cell division in higher eukaryotes is driven by a microtubule spindle formed in the cytoplasm. To allow the interaction of microtubules and chromosomes, the nuclear envelope breaks
Chromosome segregation during cell division in higher eukaryotes is driven by a microtubule spindle formed in the cytoplasm. To allow the interaction of microtubules and chromosomes, the nuclear envelope breaks down in prophase, leading to an ‘open’ mitosis. Nuclear envelope breakdown occurs by stepwise disassembly of nuclear pore complexes, inner nuclear membrane proteins and, finally, lamins,...

T iming the breakdown Before chromosomes can go their separate ways during mitosis, the nuclear envelope has to dissolve. As Hebbar et al. reveal, breakdown of the membrane might infl uence the fate of cells in the developing brain by controlling when they divide. The ventricular zone is the developing brain's maternity ward, where stem cells give birth to neurons and other cell types. Within t...
