CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

Advanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]

, 2005
Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

Advanced Science, EarlyView.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]

, 2011
During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

Co‐Treatment With rhBMP‐2 and Rapamycin Modulates Osteogenesis–Adipogenesis Balance to Enhance Aged Bone Regeneration

Advanced Science, EarlyView.
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

O-GlcNAcylation Antagonizes Phosphorylation of CDH1 (CDC20 Homologue 1) [PDF]

Journal of Biological Chemistry, 2016
The anaphase promoting complex/cyclosome (APC/C) orchestrates various aspects of the eukaryotic cell cycle. One of its co-activators, Cdh1, is subject to myriad post-translational modifications, such as phosphorylation and ubiquitination. Herein we identify the O-linked N-acetylglucosamine (O-GlcNAc) modification that occurs on Cdh1.

Targeting APC/CCDC20 by Pro-TAME Suppresses Tumor Proliferation and Induces Apoptosis in Endometrial Carcinoma

Clinical and Experimental Obstetrics & Gynecology
Background: Anaphase-promoting complex/cyclosome (APC/C) is a multi-subunit E3 ubiquitin ligase that recruits substrates for ubiquitination and subsequent degradation.

Positive Feedback Keeps Duration of Mitosis Temporally Insulated from Upstream Cell-Cycle Events [PDF]

, 2016
Cell division is characterized by a sequence of events by which a cell gives rise to two daughter cells. Quantitative measurements of cell-cycle dynamics in single cells showed that despite variability in G1-, S-, and G2 phases, duration of mitosis is ...

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

Brain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.
