Genome‐wide network analysis identifies the lncRNA‐92467/miR‐205‐5p/PTPRM/CAMs axis in a rat model of hypoxic pulmonary hypertension

open access: yesAnimal Models and Experimental Medicine, EarlyView.
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 ...

Tyrosine dephosphorylated cortactin downregulates contractility at the epithelial zonula adherens through SRGAP1

open access: yesNature Communications, 2017
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

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

open access: yesThe Anatomical Record, EarlyView.
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

open access: yesCell Reports, 2017
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 ...

Virtual adherens junctions

open access: yesThe Journal of Cell Biology, 2005
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]

open access: yes, 2007
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

open access: yesCytoskeleton, EarlyView.
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 ...

Fibroblast growth factor signaling potentiates VE-cadherin stability at adherens junctions by regulating SHP2.

open access: yesPLoS ONE, 2012
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

open access: yesThe Journal of Biochemistry, 2019
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 ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

open access: yesDevelopmental Dynamics, EarlyView.
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
