This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Stem and progenitor cell mitosis is essential for tissue development and homeostasis. How these cells ensure proper chromosome segregation, and thereby maintain mitotic fidelity, in the complex physiological environment of a living animal is poorly ...

Experiments in Xenopus embryo extracts reveal that changes in cellular biochemistry cause mitotic spindles to decrease in size over the course of early development.

The coordination of nuclear envelope assembly and chromosome segregation in metazoans
The nuclear envelope (NE) is composed of two lipid bilayer membranes that enclose the eukaryotic genome. In interphase, the NE is perforated by thousands of nuclear pore complexes (NPCs), which allow transport in and out of the nucleus. During mitosis in

Molecular, genetic, virological, and biochemical analysis in combination with global proteome and phosphoproteome profiling and functional assays were applied to study the role of PR130 in the context of HSV‐1 replication. The observations reveal that host‐intrinsic mechanisms regulate HSV‐1 replication and highlight PR130 as a susceptibility factor of

Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation
Several studies have shown that RNAi-mediated depletion of splicing factors (SFs) results in mitotic abnormalities. However, it is currently unclear whether these abnormalities reflect defective splicing of specific pre-mRNAs or a direct role of the SFs ...

Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

PHOSPHORYLATION CHANGES DURING EGG ACTIVATION AND ON REGULATORS OF THE FIRST EMBRYONIC CELL CYCLE IN DROSOPHILA [PDF]
At the transition from oocyte to embryo, a quiescent mature oocyte is transformed in a short span of time to a rapidly dividing embryo. In the first two hours of Drosophila melanogaster embryogenesis there is very little transcription of the zygotic ...

Borealin : a novel chromosomal passenger required for stability of the bipolar mitotic spindle [PDF]
The chromosomal passenger complex of Aurora B kinase, INCENP, and Survivin has essential regulatory roles at centromeres and the central spindle in mitosis. Here, we describe Borealin, a novel member of the complex.
