The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

EVALUATION OF THE GENETIC STABILITY OF PLANTS OBTAINED VIA SOMATIC EMBRYOGENESIS IN Chrysanthemum × grandiflorum (Ramat./Kitam.)

Acta Scientiarum Polonorum: Hortorum Cultus, 2015
Genetic and phenotypic stability of plants obtained via somatic embryogenesis may be disrupted. The reason can be an indirect regeneration of somatic embryos via callus or a high concentration of growth regulators added at the induction stage of somatic

Paternal Exposure to the Neonicotinoid Pesticide Clothianidin Alters Sperm MicroRNA Profiles in Mice and Intergenerationally Reduces Locomotor Activity in Male Offspring

Journal of Applied Toxicology, EarlyView.
ABSTRACT Accumulating evidence suggests that paternal environmental factors have epigenetic effects on sperm and influence offspring. Neonicotinoid pesticides (NNs), which are widely used around the world, are known to affect offspring phenotypes through maternal exposure in mice, but the effect of the paternal exposure remains unknown.

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 ...

Establishment of a glucocorticoid inducible system for regulating somatic embryogenesis in Liriodendron hybrids

Forestry Research
The precise expression of transcription factors (TFs) is crucial for plant growth and development, especially during somatic embryogenesis. However, conventional overexpression approaches, commonly used for functional genetics, can lead to deleterious ...

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

Somatic embryos formation from immature cotyledons in Phaseolus vulgaris cv. CIAP 7247

Biotecnología Vegetal, 2011
Common bean, like most of legumes, is recalcitrant to in vitro culture, so the establishment of a regeneration procedure via somatic embryogenesis in this specie has not been possible.

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 ...

The WOX Genes from the Intermediate Clade: Influence on the Somatic Embryogenesis in Medicago truncatula

Plants
Transcription factors from the WOX family are well-known regulators of cell proliferation and differentiation in plants. Herein, we focused on several WOX genes from the intermediate clade and checked their impact on somatic embryogenesis using the model

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.
