Binucleation ramps up gene expression meeting the physiological demands of an organism

PLoS Biology, 2022
In this issue of PLOS Biology, van Rijnberk and colleagues show how polyploidy, via binucleation, enables Caenorhabditis elegans intestinal cells to ramp up gene expression supplying the oocytes with the necessary lipids for optimal organismal growth and

Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey

eLife, 2017
To study the molecular basis for predator-prey coevolution, we investigated how Caenorhabditis elegans responds to the predatory fungus Arthrobotrys oligospora. C. elegans and other nematodes were attracted to volatile compounds produced by A. oligospora.

Caenorhabditis elegans Responses to Specific Steroid Hormones [PDF]

, 2003
In this paper, Caenorhabditis elegans (C. elegans) is proposed as a model organism for studying chemical effects over multiple generations. We investigated whether C. elegans responds to vertebrate steroid hormones.

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis

Advanced Science, EarlyView.
A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.

Prereplication complex proteins get caught moonlighting

PLoS Biology, 2022
In this issue of PLOS Biology, Lattmann and colleagues report a new function for proteins of the DNA prereplication complex promoting the anchor cell to invade through the basement membrane and initiate vulval development in Caenorhabditis elegans.

Global proteomics analysis of the response to starvation in C. elegans [PDF]

, 2015
Periodic starvation of animals induces large shifts in metabolism, but may also influence many other cellular systems and can lead to adaption to prolonged starvation conditions.

NECROTIC NEURODEGENERATION IN CAENORHABDITIS ELEGANS

TheScientificWorldJOURNAL, 2001
Necrosis plays a central role in neuronal injury associated with stroke and ischemia. Unlike apoptotic cell death, little is understood of molecular mechanisms of necrosis. The two distinct forms of cell death, necrosis and apoptosis, are easily distinguishable by morphological characteristics in the nematode Caenorhabditis elegans.

Pericentrosomal Redistribution of the Endoplasmic Reticulum Ensures Organelle Symmetric Inheritance and Mitotic Progression

Advanced Science, EarlyView.
Upon mitotic entry, RTN4 relocalizes to the pericentrosomal region, forming a more tubular ER network around centrosomes. CDK1‐mediated phosphorylation of RTN4 increases its interaction with Rab11 GTPase, facilitating dynein‐dependent transport of RTN4 to the pericentrosomal region.

"Caenorhabditis elegans" TEN-1 is essential for basement membrane function [PDF]

, 2008
Teneurins are large transmembrane proteins playing fundamental roles in development. They are highly expressed in the developing and adult nervous system in distinct layers, often in interconnected regions of the brain, where they were proposed to have ...

Preparation, Component Identification, and Antioxidant Activity of Anthocyanins From Punica granatum “Tunisia”

AgriFood: Journal of Agricultural Products for Food, EarlyView.
The preparation for Tunisian pomegranate anthocyanin extract. The molecular mechanisms underlying the antioxidant effects of these compounds were investigated using network pharmacology and molecular docking. Antioxidant activity was evaluated through DPPH, ABTS, and FRAP assays, whereas the effects on oxidative stress and inflammation were examined in
