Air-drying of cells enables visualization of antiparallel microtubule overlaps in the spindle midzone

MethodsX, 2018
Immunofluorescence staining is used extensively to examine various types of cellular events. However, even when an antibody can detect its epitopes in western blotting, it sometimes fails to detect its epitopes when used for immunofluorescence staining ...

Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights

Health Care Science, EarlyView.
This review elucidates the crosstalk between Parkinson's disease and colorectal cancer, driven by shared genetics (PRKN, PINK1, DJ‐1) involving oxidative stress, cell cycle regulation, and inflammation. It identifies the gut microbiota—via functional amyloids and short‐chain fatty acids (SCFAs)—as a mechanistic bridge, offering insights for dual ...

Chromosome Bridges Maintain Kinetochore-Microtubule Attachment throughout Mitosis and Rarely Break during Anaphase. [PDF]

PLoS ONE, 2016
Accurate chromosome segregation during cell division is essential to maintain genome stability, and chromosome segregation errors are causally linked to genetic disorders and cancer.

Two near‐complete assemblies reveal R‐subgenome structural and centromeric divergence associated with reproductive isolation in hexaploid triticale

iMeta, EarlyView.
We present two near‐complete triticale genome assemblies and perform pan‐centromere analyses across >200 haplotypes from parental species, synthetic allopolyploids, cultivars, and 337 resequenced accessions, revealing a shared chromatin framework underlying functional centromeres in all three subgenomes, where wheat‐ and rye‐derived CENH3 co‐occupy ...

The RepID–CRL4 ubiquitin ligase complex regulates metaphase to anaphase transition via BUB3 degradation

Nature Communications, 2020
The spindle assembly checkpoint (SAC) safeguards chromosome segregation by regulating the anaphase promoting complex/cyclosome (APC/C), allowing chromosomes to correctly attach to mitotic spindles. Here the authors reveal a role for Cullin–RING ubiquitin

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

Chromosomal and immune dysregulation underlying granular mitosis in glioblastoma

Brain Pathology, EarlyView.
Granular mitosis (GM) morphology is linked to PI3K/PTEN pathway alterations, chromosomal disorganization, and impaired innate immunity. Cells exhibiting GM morphology are associated with localized immune responses within their immediate spatial microenvironment.
