Advanced Science, EarlyView.Klinefelter syndrome‐derived iPSCs provide an excellent model for studying X chromosome inactivation and functions of escapee genes during human primordial germ cell‐like cells differentiation process. Downregulation of three X‐linked genes—IGSF1, CHRDL1, and USP9X—significantly enhances the efficiency of hPGCLCs.

Nucleus, 2020 Elastic tethers, connecting telomeres of all separating anaphase chromosome pairs, lose elasticity when they lengthen during anaphase. Treatment with phosphatase inhibitor CalyculinA causes anaphase chromosomes to move backwards after they reach the ...

eLife, 2020 During mitosis, the Spindle Assembly Checkpoint (SAC) maintains genome stability while also ensuring timely anaphase onset. To maintain genome stability, the SAC must be strong to delay anaphase even if just one chromosome is unattached, but for timely ...

Novel regulation of mitotic exit by the Cdc42 effectors Gic1 and Gic2 [PDF]
, 2004 Copyright @ The Rockefeller University PressThe guanine nucleotide exchange factor Cdc24, the GTPase Cdc42, and the Cdc42 effectors Cla4 and Ste20, two p21-activated kinases, form a signal transduction cascade that promotes mitotic exit in yeast.

Chemotherapy‐Mediated Induction of PD‐L1 via SEI1 Facilitates Myeloma Immune Evasion
Advanced Science, EarlyView.Chemotherapy induces DNA damage, activating cyclic guanosine monophosphate (GMP)‐adenosine monophosphate (AMP) synthase (cGAS)/stimulator of interferon genes (STING), which phosphorylates interferon regulatory factor 7 (IRF7) to drive SERTA‐containing domain 1 (SEI1) transcription.

Anaphase A: Disassembling Microtubules Move Chromosomes toward Spindle Poles
Biology, 2017 The separation of sister chromatids during anaphase is the culmination of mitosis and one of the most strikingly beautiful examples of cellular movement.

Asymmetrical inheritance of plasmids depends on dynamic cellular geometry and volume exclusion effects [PDF]
, 2015 The asymmetrical inheritance of plasmid DNA, as well as other cellular components, has been shown to be involved in replicative aging. In Saccharomyces cerevisiae, there is an ongoing debate regarding the mechanisms underlying this important asymmetry. Currently proposed models suggest it is established via diffusion, but differ on whether a diffusion ...

Advanced Science, EarlyView.Sperm‐derived circRNA‐1572 competitively binds to bta‐miR‐2478‐L‐2 through a “sponge” mechanism to regulate cyclin B2 (CCNB2) expression, thereby modulating the distribution of fibrous actin (F‐actin) in early pig embryos, ensuring proper chromosome segregation during mitosis, and facilitating normal embryo cleavage and zygotic genome activation.

Condensin II resolves chromosomal associations to enable anaphase I segregation in Drosophila male meiosis. [PDF]
PLoS Genetics, 2008 Several meiotic processes ensure faithful chromosome segregation to create haploid gametes. Errors to any one of these processes can lead to zygotic aneuploidy with the potential for developmental abnormalities.

Holocentric Chromosomes of Luzula elegans Are Characterized by a Longitudinal Centromere Groove, Chromosome Bending, and a Terminal Nucleolus Organizer Region [PDF]
, 2011 The structure of holocentric chromosomes was analyzed in mitotic cells of Luzula elegans. Light and scanning electron microscopy observations provided evidence for the existence of a longitudinal groove along each sister chromatid.
