β‐Catenin localization in the ctenophore Mnemiopsis leidyi suggests an ancestral role in cell adhesion and nuclear function

Developmental Dynamics, EarlyView.
Abstract Background The emergence of multicellularity in animals marks a pivotal evolutionary event, which was likely enabled by molecular innovations in the way cells adhere and communicate with one another. β‐Catenin is significant to this transition due to its dual role as both a structural component in the cadherin–catenin complex and as a ...

Modulatory effect of Picralima Nitida on oxidative stress: Cobalt, thiol, total protein in Drosophila melanogaster exposed to lead

Sokoto Journal of Medical Laboratory Science, 2023
Drosophila melanogaster, commonly known as fruit fly, vinegar fly, is a small model organism used in the study of various disciplines. D. biochemical, neurological and physiological sim ilarities with human beings and has about 75% functional homologs of

The bacterial symbiont Wolbachia induces resistance to RNA viral infections in Drosophila melanogaster. [PDF]

PLoS Biology, 2008
Wolbachia are vertically transmitted, obligatory intracellular bacteria that infect a great number of species of arthropods and nematodes. In insects, they are mainly known for disrupting the reproductive biology of their hosts in order to increase their

Attraction to natural stimuli in Drosophila melanogaster [PDF]

arXiv, 2009
The animals, in particular insects (Drosophila melanogaster), response towards odor stimuli in nature can be established by measuring the dynamic of the odor response. Such an approach is innovative since responses to odors were tested only at certain time point so far, not in hour intervals for several hours.

mRNA active transport in oocyte-early embryo: 3D agent-based modeling [PDF]

arXiv, 2023
Axes of polarity (and primary morphogenetic gradients) are established in the oocyte - early embryo through active transport and localization of maternal factors. It is the oocyte - syncytial embryo of Drosophila (D. melanogaster) that is a model object for studying the molecular machinery of such transport systems.

Locomotor Assay in Drosophila melanogaster

BIO-PROTOCOL, 2017
This protocol describes a simple locomotor assay in Drosophila melanogaster. In brief, the locomotor of each single fly in the culture dish is recorded by a web camera. The moving time, walking length, speed and the locomotor trails of the single fly could be quantitatively analyzed.

Effects of life history strategies and habitats on limb regeneration in plethodontid salamanders

Developmental Dynamics, EarlyView.
Abstract Background Salamanders are the only tetrapods that exhibit the ability to fully regenerate limbs. The axolotl, a neotenic salamander, has become the model organism for regeneration research. Great advances have been made providing a detailed understanding of the morphological and molecular processes involved in limb regeneration.

A protein restricted diet induces a stable increased fat storage phenotype in flies

Toxicology Reports, 2023
Background: Scientific evidence has revealed possible confounders in diet induced obesity models of Drosophila melanogaster. High Sugar Diet (HSD) induction of obesity in flies has been associated with fly hyperosmolarity and glucotoxicity, while High ...

Infection Dynamics and Immune Response in a Newly Described Drosophila-Trypanosomatid Association

mBio, 2015
Trypanosomatid parasites are significant causes of human disease and are ubiquitous in insects. Despite the importance of Drosophila melanogaster as a model of infection and immunity and a long awareness that trypanosomatid infection is common in the ...

Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...
