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

Blocking microtubule deacetylation inhibits anaphase chromosome movements in crane-fly spermatocytes.

PLoS ONE
Chromosome movement speeds during anaphase are regulated by depolymerization of microtubules. Several models describe chromosome movement during cell division but none of them consider post-translational modifications of tubulin, even though such ...

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease

Cdk1 inactivation induces post-anaphase-onset spindle migration and membrane protrusion required for extreme asymmetry in mouse oocytes

Nature Communications, 2018
Female meiotic divisions are asymmetric with the formation of large oocytes and small polar bodies, thought to result from cortical spindle placement before anaphase.

Pedunculoside Inhibits Hepatocellular Carcinoma Progression by Activating the MAPK Signaling Pathway Through Targeting and Suppressing CDK4

Phytotherapy Research, EarlyView.
Pedunculoside targets and suppresses CDK4; consequently, it activates the MAPK pathway and inhibits hepatocellular carcinoma progression. ABSTRACT Hepatocellular carcinoma (HCC) remains a major challenge in cancer prevention and treatment, highlighting the urgent need for effective and low‐toxicity anti‐HCC therapies. Recently, CDK4‐targeted inhibitors

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 ...

Dynamic SUMO remodeling drives a series of critical events during the meiotic divisions in Caenorhabditis elegans.

PLoS Genetics, 2018
Chromosome congression and segregation in C. elegans oocytes depend on a complex of conserved proteins that forms a ring around the center of each bivalent during prometaphase; these complexes are then removed from chromosomes at anaphase onset and ...

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Cyclin B3 activates the Anaphase-Promoting Complex/Cyclosome in meiosis and mitosis.

PLoS Genetics, 2020
In mitosis and meiosis, chromosome segregation is triggered by the Anaphase-Promoting Complex/Cyclosome (APC/C), a multi-subunit ubiquitin ligase that targets proteins for degradation, leading to the separation of chromatids.
