The epithelial sodium channel in the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi).
Epithelial sodium channel (ENaC) is a Na(+)-selective, aldosterone-stimulated ion channel involved in sodium transport homeostasis. ENaC is rate-limiting for Na(+) absorption in the epithelia of osmoregulatory organs of tetrapods. Although the ENaC/degenerin gene family is proposed to be present in metazoans, no orthologues or paralogues for ENaC have been found in the genome databases of teleo...
متن کاملModification of Cytoskeletal Proteins by Lipid-derived Aldehydes in the Lens Epithelial Cells
Oxidative stress has been implicated both in senile and diabetic cataractogenesis and recent evidence suggest that the lipid peroxidation product, 4-hydroxynonenal (HNE) mediates the oxidation-induced toxicity. Using human lens epithelial cells (HLEC) and rat lens we have demonstrated that HNE and oxidants such as Fenton reagent induce opacification in the rat lens and apoptosis in HLEC and len...
متن کاملWnt4 regulates thymic cellularity through the expansion of thymic epithelial cells and early thymic progenitors.
Thymus atrophy is the most common immunopathology in humans, and its occurrence is hastened by several factors that coalesce in patients receiving chemotherapy and most of all in recipients of hematopoietic cell transplantation. We have shown previously that posthematopoietic cell transplantation thymic function was improved by retroviral overexpression of Wnt4 in donor hematopoietic cells. Her...
متن کاملTranscriptome sequencing of neonatal thymic epithelial cells
In order to gain novel insights into thymus biology, we analysed the whole transcriptome of cortical and medullary thymic epithelial cells (cTECs and mTECs) and of skin epithelial cells (ECs). Consistent with their ability to express ectopic genes, mTECs expressed more genes than other cell populations. Out of a total of 15,069 genes expressed in TECs, 25% were differentially expressed by at le...
متن کاملHistophysiology of thymic epithelial reticular cells.
Thymic epithelial reticular cells together with lymphocytes constitute the thymic parenchyma. Morphologically they are characterized by the stellate aspect forming a cytoreticulum, a large and vesicular nucleus, a tonofilament-rich cytoplasm, and abundance of desmosomes. Besides the role of providing a structural support for lymphocytes, epithelial reticular cells are responsible for the secret...
