Ultrastructural analysis of the structure and distribution of the adherens junctions in the rats’ ventricular myocardium during postnatal stages of ontogeny after the infl uence of chronic prenatal hypoxia

Patologìâ, 2013
Background. Antenatal and prenatal hypoxia causes changes in all the organs of fetuses and newborns and in the heart, particularly. Hypoxic damage of the cardiovascular system occurs in 40-70% of newborns.

Cell junctions during morphogenesis of feathers: general ultrastructure with emphasis on adherens junctions

, 2010
The present ultrastructural and immunocytochemical study analyzes the cell junctions joining barb ⁄ barbule cells versus cell junctions connecting supportive cells in forming feathers. Differently from the epidermis or the sheath, desmosomes are not the

Loss of Twist1 leads to disruption of ciliary length, endocytic vesicle dynamics, and cell–cell junctions during neural tube formation

Developmental Dynamics, EarlyView.
Abstract Background Endocytosis constitutes a fundamental cellular process governing development through coordinated regulation of plasma membrane remodeling and ciliogenesis, processes essential for cell shape changes and tissue development. Although Twist1 null embryos display complete cranial neural tube (NT) closure defects and conditional knockout

Restraint Stress Induced Hyperpermeability and Damage of the Blood-Brain Barrier in the Amygdala of Adult Rats

Frontiers in Molecular Neuroscience, 2019
Intense or prolonged exposure to stress can damage various brain structures, including the amygdala and hippocampus, which are associated with emotional-cognitive functions. Furthermore, this deterioration has been linked to a myriad of neurodegenerative

Formin' adherens junctions

The Journal of Cell Biology, 2003
Epithelial cells zipper together thanks to linear actin cables—cables that assemble at newly formed adherens junctions to stabilize them, thereby counteracting retractive forces at sites of cell–cell contact. Now, Agnieszka Kobielak, Amalia Pasolli, and Elaine Fuchs (Rockefeller University, New York, NY) have found that formin-1 drives the actin ...

Tight junctions negatively regulate mechanical forces applied to adherens junctions in vertebrate epithelial tissue

, 2017
International audienceEpithelia are layers of polarised cells tightly bound to each other by adhesive contacts. Epithelia act as barriers between an organism and its external environment.

DNA Methylation and Transcriptomic Profiles of Wilms Tumour Reveal New Deregulated Genes and Epigenetic Processes Relevant for Tumour Stratification and Management

International Journal of Cancer, EarlyView.
ABSTRACT Wilms Tumour (WT), the most common kidney cancer in children, presents features of altered kidney development and frequently exhibits molecular alterations at the 11p15.5 imprinted locus, affecting the IGF2 and H19 genes, which contribute to tumour growth and predisposition.

Immune Checkpoint Inhibitors Induce Intestinal Epithelial Injury and a Senescence‐Like Phenotype

iNew Medicine, EarlyView.
ICI treatment promotes the infiltration of activated immune cells into the intestinal mucosa. This inflammatory microenvironment is associated with significant epithelial injury, characterized by the disruption of the epithelial barrier, the depletion of specialized secretory cell lineages, and the induction of a premature senescence phenotype ...

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

DHT deficiency perturbs the integrity of the rat seminiferous epithelium by disrupting tight and adherens junctions

Folia Histochemica et Cytobiologica, 2011
In rats with a DHT deficiency induced by finasteride, morphological changes in the seminiferous epithelium were observed. The structural alterations were manifested by the premature germ cells sloughing into the lumen of seminiferous tubules.
