Transient defects of mitotic spindle geometry and chromosome segregation errors
Cell Division, 2012 Assembly of a bipolar mitotic spindle is essential to ensure accurate chromosome segregation and prevent aneuploidy, and severe mitotic spindle defects are typically associated with cell death. Recent studies have shown that mitotic spindles with initial

Evolution of an ancient protein function involved in organized multicellularity in animals. [PDF]
, 2016 To form and maintain organized tissues, multicellular organisms orient their mitotic spindles relative to neighboring cells. A molecular complex scaffolded by the GK protein-interaction domain (GKPID) mediates spindle orientation in diverse animal taxa ...

Mechanisms of Mitotic Spindle Assembly [PDF]
Annual Review of Biochemistry, 2016 Life depends on cell proliferation and the accurate segregation of chromosomes, which are mediated by the microtubule (MT)-based mitotic spindle and ∼200 essential MT-associated proteins. Yet, a mechanistic understanding of how the mitotic spindle is assembled and achieves chromosome segregation is still missing.

ATM controls proper mitotic spindle structure [PDF]
Cell Cycle, 2014 The recessive ataxia-telangiectasia (A-T) syndrome is characterized by cerebellar degeneration, immunodeficiency, cancer susceptibility, premature aging, and insulin-resistant diabetes and is caused by loss of function of the ATM kinase, a member of the phosphoinositide 3-kinase-like protein kinases (PIKKs) family.

KDM4A Erases the H3R17me2a Mark, Facilitating Chromosome Condensation
Advanced Science, EarlyView.This study reveals a reversible histone modification switch governing chromosome condensation during mitosis. PKCα‐activated KDM4A removes H3R17me2a, permitting Suv39h1‐driven H3K9me3 deposition. This epigenetic transition recruits the chromosomal passenger complex and triggers Aurora B‐dependent H3S10 phosphorylation, coordinating chromatin remodeling

eLifeThe spindle assembly checkpoint (SAC) temporally regulates mitosis by preventing progression from metaphase to anaphase until all chromosomes are correctly attached to the mitotic spindle.

, 2018 The C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules.

Advanced Science, EarlyView.Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Mitotic cell death induction by targeting the mitotic spindle with tubulin-inhibitory indole derivative molecules [PDF]
, 2017 Tubulin-targeting molecules are widely used cancer therapeutic agents. They inhibit microtubule-based structures, including the mitotic spindle, ultimately preventing cell division.

Temporal Interference Stimulation Enhances Neural Regeneration
Advanced Science, EarlyView.Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.
