Alternative Developmental Toxicity Screening Methods Using Chick Embryo‐Based Models

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nonclinical developmental toxicity studies are used to investigate the potential toxicities of drugs and chemical candidates on normal embryonic and fetal development during pregnancy, generally using mammalian laboratory animals such as rats and rabbits.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

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

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

LEC2 induces somatic cell reprogramming through epigenetic activation of plant cell totipotency regulators

Nature Communications
Many plant species can develop embryos from somatic cells without fertilization. During this process, known as somatic embryogenesis, changes in the DNA methylation patterns are characteristic of reprogramming somatic cells into an embryogenic state ...

The effect of non‐surgical periodontal treatment on progranulin levels

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study was to study the effect of non‐surgical periodontal therapy (NSPT) on gingival crevicular fluid (GCF) and serum progranulin (PGRN) levels in the early healing phases. Methods The study included periodontitis (test) (n = 24) and periodontal health (control) (n = 24) groups.

Anther Culture in Pepper (Capsicum annuum L.)

Journal of Agriculture and Plant Sciences, 2013
Somatic embryogenesis has been defined as the developmental process producing a perfect embryo from a single cell, which achieves bipolar at as a stage as occurs in zygotic embryogenesis.

Transcriptomic comparative study between canalicular adenoma and HMGA2::WIF1 canalicular‐like pleomorphic adenoma

The Journal of Pathology, EarlyView.
Abstract Canalicular adenoma (CA) is a benign salivary gland tumor predominantly affecting the upper lip and is characterized by monomorphic epithelial cells arranged in branching cords within a loose and vascularized stroma. Unlike pleomorphic adenoma (PA), CA lacks a chondroid matrix and exhibits specific histological features, such as high cuboidal ...
