PLK4: Master Regulator of Centriole Duplication and Its Therapeutic Potential

open access: yesCytoskeleton, EarlyView.
ABSTRACT Centrosomes catalyze the assembly of a microtubule‐based bipolar spindle, essential for the precise chromosome segregation during cell division. At the center of this process lies Polo‐Like Kinase 4 (PLK4), the master regulator that controls the duplication of the centriolar core to ensure the correct balance of two centrosomes per dividing ...

Centromere deletion in Cryptococcus deuterogattii leads to neocentromere formation and chromosome fusions

open access: yeseLife, 2020
The human fungal pathogen Cryptococcus deuterogattii is RNAi-deficient and lacks active transposons in its genome. C. deuterogattii has regional centromeres that contain only transposon relics.

Speciation Mediated by Centromeres [PDF]

open access: yesDevelopmental Cell, 2013
Speciation accompanies reproductive isolation in natural populations through hybrid sterility or lethality. However, the molecular bases of hybrid lethality are mysterious. In this issue of Developmental Cell, Thomae et al. (2013) demonstrate that Drosophila speciation factors HMR and LHR form a centromeric complex and that increased dosage causes ...

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Bioinformatics analysis of immune‐programmed cell death‐related genes in nasopharyngeal carcinoma

open access: yesEye &ENT Research, EarlyView.
Abstract Background Nasopharyngeal carcinoma (NPC) is a prevalent malignant tumor of the head and neck, characterized by a complex pathogenesis. Most newly diagnosed NPC patients are locally advanced, and 20%–30% of advanced NPC patients have poor immunotherapy results.

CENP-A Ubiquitylation Is Inherited through Dimerization between Cell Divisions

open access: yesCell Reports, 2016
The presence of chromatin containing the histone H3 variant CENP-A dictates the location of the centromere in a DNA sequence-independent manner. But the mechanism by which centromere inheritance occurs is largely unknown. We previously reported that CENP-

The micronucleus assay in radiation accidents [PDF]

open access: yes, 2009
The cytokinesis-block micronucleus assay in peripheral blood lymphocytes is a standardised and validated technique for biodosimetry. Automated scoring of micronuclei allows large scale applications as in population triage in case of radiation accidents ...

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]

open access: yes, 2015
The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.
