The pathogenesis of hypoxic pulmonary hypertension (HPH) remains unclear. In this study, we explored its key regulatory mechanisms using animal models, RNA sequencing, and cellular assays. We found that lncRNA‐92467 functions as a ceRNA, binding miR‐205‐5p, and thereby upregulating PTPRM, inhibiting abnormal proliferation and migration of endothelial ...

Epithelial cell-cell adhesions are contractile junctions, but whether contractility can be down-regulated is not known. Here the authors report how tyrosine dephosphorylation of the cytoskeletal scaffold, cortactin, recruits the RhoA antagonist SRGAP1 to

Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

αE-Catenin Is a Positive Regulator of Pancreatic Islet Cell Lineage Differentiation
The development and function of epithelia depend on the establishment and maintenance of cell-cell adhesion and intercellular junctions, which operate as mechanosensor hubs for the transduction of biochemical signals regulating cell proliferation ...

The textbook model of adherens junctions has been exploded, or severed, by Bill Weis, Soichiro Yamada, Frauke Drees, Sabine Pokutta, and W. James Nelson (Stanford University School of Medicine, Stanford, CA). There is no direct link, they say, between cadherin, via β- and α-catenin, to actin.

Cell polarity development and protein trafficking in hepatocytes lacking E-cadherin/beta-catenin-based adherens junctions [PDF]
Using a mutant hepatocyte cell line in which E-cadherin and ss-catenin are completely depleted from the cell surface, and, consequently, fail to form adherens junctions, we have investigated adherens junction requirement for apical-basolateral polarity ...

Labeling Strategies for Monitoring Cytoskeleton Dynamics in Cultured Epithelial Cells
ABSTRACT Collective cell migration relies on coordinated cytoskeletal remodeling, yet the impact of live‐cell actin filament probes on these dynamics remains poorly characterized. Here, we systematically compared the performance and cellular effects of fluorogenic jasplakinolide‐based probes, SiR‐actin and SiR‐XActin, with the genetically encoded ...

BackgroundThe fibroblast growth factor (FGF) system plays a critical role in the maintenance of vascular integrity via enhancing the stability of VE-cadherin at adherens junctions. However, the precise molecular mechanism is not well understood.

Plasmalogen mediates integration of adherens junction
AbstractEther glycerolipids, plasmalogens are found in various mammalian cells and tissues. However, physiological role of plasmalogens in epithelial cells remains unknown. We herein show that synthesis of ethanolamine-containing plasmalogens, plasmenylethanolamine (PlsEtn), is deficient in MCF7 cells, an epithelial cell line, with severely reduced ...

Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common
