Cell autonomous polarization by the planar cell polarity signaling pathway. [PDF]
Abstract As epithelial cells polarize in the tissue plane, the Planar Cell Polarity (PCP) signaling module segregates two distinct molecular subcomplexes to opposite sides of cells. Homodimers of the atypical cadherin Flamingo form bridges linking opposite complexes in neighboring cells, coordinating their direction of polarization ...

Establishing cell polarity in plants: the role of cytoskeletal structures and regulatory pathways [PDF]
Cell polarity is a fundamental mechanism of plant cells that drives cellular specialization and the formation of diverse cell types. It regulates critical developmental events, including polarized tip growth (such as pollen tubes and root hairs ...

Background Transmembrane and immunoglobulin domain-containing protein 1 (TMIGD1) is a recently identified cell adhesion molecule which is predominantly expressed by epithelial cells of the intestine and the kidney. Its expression is downregulated in both

TJP2/ZO-2-inactivating mutations in humans cause progressive cholestatic liver disease. Liver-specific deletion of Tjp2 in the mouse (Tjp2 cKO mice) leads to mild progressive cholestasis without an overt degradation of the bile-blood barrier (BBB). These

Cell Polarity: The importance of being polar [PDF]
Cell polarization is often accompanied by cytoskeletal rearrangements. Two signalling proteins, a GTPase and a kinase, are required for both actin and microtubule rearrangements. Are these two systems coupled?

Cell Adhesion at the Tight Junctions: New Aspects and New Functions
Tight junctions (TJ) are cell–cell adhesive structures that define the permeability of barrier-forming epithelia and endothelia. In contrast to this seemingly static function, TJs display a surprisingly high molecular complexity and unexpected dynamic ...

Cell polarity: Par for the polar course [PDF]
The nematode PAR-1 gene is required for asymmetric cell divisions during development. Recently identified mammalian Par-1 homologues are kinases that phosphorylate microtubule-associated proteins; their overexpression disrupts the microtubule cytoskeleton, and alters cellular structure and organization.

Intermediate Filaments from Tissue Integrity to Single Molecule Mechanics
Cytoplasmic intermediate filaments (IFs), which together with actin and microtubules form the cytoskeleton, are composed of a large and diverse family of proteins.

A conserved molecular machinery centered on the Cdc42 GTPase regulates cell polarity in diverse organisms. Here we review findings from budding and fission yeasts that reveal both a conserved core polarity circuit and several adaptations that each organism exploits to fulfill the needs of its lifestyle.

PTEN inhibits AMPK to control collective migration
Pten is a tumour suppressor gene that is associated with highly invasive cancers such as glioblastoma. Here the authors show that PTEN loss results in increased migratory behaviour, which can be countered by targeting AMPK activity.
