PLK4: Master Regulator of Centriole Duplication and Its Therapeutic Potential
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 ...

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.

The dark side of centromeres: types, causes and consequences of structural abnormalities implicating centromeric DNA [PDF]
Centromeres are the chromosomal domains required to ensure faithful transmission of the genome during cell division. They have a central role in preventing aneuploidy, by orchestrating the assembly of several components required for chromosome separation.

The multiple functions of kinetochores are reflected in their complex composition, with over a hundred different proteins, which self-associate in several functional subcomplexes. Most of these kinetochore proteins were identified over the last 10-12 years using a combination of genetic, cell biological, biochemical, and bioinformatic approaches in ...

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

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.

Holocentric Chromosomes of Luzula elegans Are Characterized by a Longitudinal Centromere Groove, Chromosome Bending, and a Terminal Nucleolus Organizer Region [PDF]
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.

Abstract Gene expression biomarkers have the potential to identify genotoxic and non‐genotoxic carcinogens, providing opportunities for integrated testing and reducing animal use. In August 2022, an International Workshops on Genotoxicity Testing (IWGT) workshop was held to critically review current methods to identify genotoxicants using ...

Kinetochores move chromosomes on dynamic spindle microtubules and regulate signaling of the spindle checkpoint. The Spindle and Kinetochore-Associated (Ska) Complex, a hexamer composed of two copies of Ska1, Ska2 and Ska3, has been implicated in both roles.

Mechanisms of enhancer‐driven oncogene activation
Abstract An aggressive subtype of acute myeloid leukemia (AML) is caused by enhancer hijacking resulting in MECOM overexpression. Several chromosomal rearrangements can lead to this: the most common (inv(3)/t(3;3)) results in a hijacked GATA2 enhancer, and there are several atypical MECOM rearrangements involving enhancers from other hematopoietic ...
