Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

open access: yesCytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Imaging the Pharynx to Measure the Uptake of Doxorubicin in Caenorhabditis elegans

open access: yesBio-Protocol, 2017
Caenorhabditis elegans offers an array of advantages to investigate the roles of uptake transporters. Herein, an epifluorescent microscopy approach was developed to monitor the uptake of the autofluorescent anticancer drug, doxorubicin, into the pharynx ...

Neurogenesis in Caenorhabditis elegans

open access: yesGENETICS
Abstract Animals rely on their nervous systems to process sensory inputs, integrate these with internal signals, and produce behavioral outputs. This is enabled by the highly specialized morphologies and functions of neurons. Neuronal cells share multiple structural and physiological features, but they also come in a large diversity of ...

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

open access: yesCytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

A practical guide to ordering C. elegans strains for biological research

open access: yesMolecules and Cells
: Caenorhabditis elegans (C. elegans) is a widely used model organism in biological research, contributing to our understanding of fundamental processes in areas such as development, neurobiology, and aging. Accessing the appropriate C.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Histone deacetylase HDA-1 modulates mitochondrial stress response and longevity

open access: yesNature Communications, 2020
Caenorhabditis elegans responds to mitochondrial stress by activating the mitochondrial unfolded protein response (UPRmt). Here the authors show that HDA-1, the C.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...
