Evidence of substrate control of Cdk phosphorylation during the budding yeast cell cycle

Cell Reports
Summary: A series of sequential events orchestrates cell growth and division, set in motion by cyclin-dependent kinases (Cdks). In the “qualitative model” for Cdk control, order is achieved by cell cycle stage-specific cyclins.

Functional Characterization and Pathogenicity Classification of PRRT2 Splice Variants in PRRT2‐Related Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Paroxysmal kinesigenic dyskinesia (PKD) is the most common hereditary paroxysmal movement disorder. The PRRT2 gene is the first identified causative gene and accounts for the majority of PKD. In this study, we investigated the pathogenicity of PRRT2 variants in the splice regions. Methods Patients with clinically suspected PKD and no

Multimodal effects of small molecule ROCK and LIMK inhibitors on mitosis, and their implication as anti-leukemia agents. [PDF]

PLoS ONE, 2014
Accurate chromosome segregation is vital for cell viability. Many cancer cells show chromosome instability (CIN) due to aberrant expression of the genes involved in chromosome segregation.

Depletion or cleavage of cohesin during anaphase differentially affects chromatin structure and segregation

eLife, 2022
Chromosome segregation requires both the separation of sister chromatids and the sustained condensation of chromatids during anaphase. In yeast cells, cohesin is not only required for sister chromatid cohesion but also plays a major role determining the ...

Expanding Hereditary Spastic Paraplegias Limits: Biallelic SPAST Variants in Cerebral Palsy Mimics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegias (HSP) are rare neurodegenerative disorders marked by spasticity and lower limb weakness. The most common type, SPG4, is usually autosomal dominant and caused by SPAST gene variants, typically presenting as pure HSP.

RAB39B Related Parkinsonism in an Italian Family: A Unique Use of Advanced Therapies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Parkinson's disease (PD) is a neurodegenerative disorder that may sometimes be caused by deleterious genetic variants. Among them, RAB39B polymorphisms are known as rare causes of early‐onset PD associated with intellectual disability (Waisman's syndrome).

Unique Function of the Bacterial Chromosome Segregation Machinery in Apically Growing Streptomyces - Targeting the Chromosome to New Hyphal Tubes and its Anchorage at the Tips.

PLoS Genetics, 2016
The coordination of chromosome segregation with cell growth is fundamental to the proliferation of any organism. In most unicellular bacteria, chromosome segregation is strictly coordinated with cell division and involves ParA that moves the ParB ...

Engineering the Link: From Genome Interaction Maps to Functional Insight

Advanced Biology, EarlyView.
Advances in chromosome conformation capture have revealed the genome's 3D organization, yet its causal impact on gene regulation remains elusive. This review highlights emerging genome‐engineering tools ‐ zinc fingers, TALEs, and CRISPR‐Cas9 ‐ that enable targeted manipulation of chromatin loops to dissect structure–function relationships. It discusses

Methylated histones on mitotic chromosomes promote topoisomerase IIα function for high fidelity chromosome segregation

iScience, 2023
Summary: DNA Topoisomerase IIα (TopoIIα) decatenates sister chromatids, allowing their segregation in mitosis. Without the TopoIIα Strand Passage Reaction (SPR), chromosome bridges and ultra-fine DNA bridges (UFBs) arise in anaphase.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.
