TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching. [PDF]
The AAA+ family ATPase TRIP13 is a key regulator of meiotic recombination and the spindle assembly checkpoint, acting on signaling proteins of the conserved HORMA domain family.

A Role of PI3K/Akt Signaling in Oocyte Maturation and Early Embryo Development
A serine/threonine-specific protein kinase B (PKB), also known as Akt, is a key factor in the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway that regulates cell survival, metabolism and proliferation.

Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

Dynactin-dependent cortical dynein and spherical spindle shape correlate temporally with meiotic spindle rotation in Caenorhabditis elegans. [PDF]
Oocyte meiotic spindles orient with one pole juxtaposed to the cortex to facilitate extrusion of chromosomes into polar bodies. In Caenorhabditis elegans, these acentriolar spindles initially orient parallel to the cortex and then rotate to the ...

In recent years, the demands for mirror finishing by cutting have increased, because the surface quality requirement in die and mold has become severer. In order to realize mirror surface finish by cutting, it is necessary to reduce the influence of tool

The novelty of this study showed that the injection of exosomes produced from ADMSCs in combination with Roflumilast poses a more favorable therapeutic outcome for CKD induced by Adriamycin, compared to therapy with exosomes or Roflumilast alone. Roflumilast and exosomes treatment lowered the expression of the apoptotic, fibrotic, and inflammatory ...

The Incredible Shrinking Spindle [PDF]
As cell size decreases during the reductive divisions of early development, intracellular structures must shrink to fit. In this issue of Developmental Cell, Lacroix et al. (2018) identify a conserved mechanism of spindle scaling in nematode and sea urchin embryos whereby spindle microtubule polymerization rates decrease as development proceeds.

Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Concentrating on the mitotic spindle [PDF]
In eukaryotes, the microtubule-based spindle drives chromosome segregation. In this issue, Schweizer et al. (2015; J. Cell Biol. http://dx.doi.org/10.1083/jcb.201506107) find that the spindle area is demarcated by a semipermeable organelle barrier. Molecular crowding, which is microtubule independent, causes the enrichment and/or retention of crucial ...

A bacteriophage tubulin harnesses dynamic instability to center DNA in infected cells. [PDF]
Dynamic instability, polarity, and spatiotemporal organization are hallmarks of the microtubule cytoskeleton that allow formation of complex structures such as the eukaryotic spindle. No similar structure has been identified in prokaryotes.
