Abstract (sommario):

AbstractCell migration is fundamental to establishing and maintaining the proper organization of multicellular organisms. Morphogenesis can be viewed as a consequence, in part, of cell locomotion, from large‐scale migrations of epithelial sheets during gastrulation, to the movement of individual cells during development of the nervous system. In an adult organism, cell migration is essential for proper immune response, wound repair, and tissue homeostasis, while aberrant cell migration is found in various pathologies. Indeed, as our knowledge of migration increases, we can look forward to, for

Abstract (sommario):

Mass migrations of dense cell populations occur periodically during embryonic development. It is known that extracellular matrices, through which the cells migrate, facilitate locomotion. However, this does not explain how cells, such as neural crest, can migrate as a dense cohort of cells in essentially continuous contact with one another. We report here that unique behavioral characteristics of the migrating cells may contribute to cohesive migration. We used time-lapse video microscopy to analyze the migration of quail neural crest cells and of two crest derivatives, human melanoma cells an

Aim. PFKFB3 is glycolytic activators that is overexpressed in human lung cancer and plays a crucial role in multiple cellular functions including programmed cell death. Despite the many small molecules described as PFKFB3 inhibitors, some of them have shown disappointing results in vitro and in vivo. On the other hand KAN0438757, selective and potent, small molecule inhibitor has been developed. However, the effects of KAN0438757, in non-small cell lung carcinoma cells remain unknown.

Abstract (sommario):

A variety of evidence suggests that fibronectin (FN) promotes cell migration during embryogenesis, and it has been suggested that the deposition of FN along migratory pathways may also play a role in cell guidance. In order to investigate such a role for FN, it is important to determine the relative contribution of migrating and pathway-forming cells to the FN in the migratory track, as any synthesis of FN by the migrating cells might be expected to mask guidance cues provided by the exogenous FN from pathway-forming cells. We have therefore used in situ hybridization to determine in developin

The role of tenascin in mediating tumor cell migration was studied using two cell migration models. In migration/invasion Transwell assays U251.3 glioma cells rapidly migrated through the 8 mu m pore size membranes onto tenascin- and fibronectin-coated surfaces. In this assay the number of cells migrating onto tenascin was 52.2 +/- 9.6% greater than on fibronectin within 4 hours. To assess cell migration rates and cell morphology, U251.3 migration was examined in a two-dimension spheroid outgrowth assay. The radial distance migrated by U251.3 cells from tumor spheroids was found to be 53.8 +/-

Abstract (sommario):

Contact inhibition of locomotion (CIL), the repulsive response of cells upon cell–cell contact, has been the predominant paradigm for contact-mediated responses. However, it is difficult for CIL alone to account for the complex behavior of cells within a multicellular environment, where cells often migrate in cohorts such as sheets, clusters, and streams. Although cell–cell adhesion and mechanical interactions play a role, how individual cells coordinate their migration within a multicellular environment remains unclear.

What information activates Hox gene expression during this cell migration? How are these cells subsequently guided to their final positions?

Cell migration involves dynamic and spatially regulated changes to the cytoskeleton and cell adhesion. The Rho GTPases play key roles in coordinating the cellular responses required for cell migration. Recent research has revealed new molecular links between Rho family proteins and the actin cytoskeleton, showing that they act to regulate actin polymerization, depolymerization and the activity of actin-associated myosins. In addition, studies on integrin signalling suggest that the substratum continuously feeds signals to Rho proteins in migrating cells to influence migration rate. There is al

Abstract (sommario):

Coordinated activation and inhibition of F-actin supports the movements of morphogenesis. Understanding the proteins that regulate F-actin is important, since these proteins are mis-regulated in diseases like cancer. Our studies of C. elegans embryonic epidermal morphogenesis identified the GTPase CED-10/Rac1 as an essential activator of F-actin. However, we need to identify the GEF, or Guanine-nucleotide Exchange Factor, that activates CED-10/Rac1 during embryonic cell migrations. The two-component GEF, CED-5/CED-12, is known to activate CED-10/Rac1 to promote cell movements that result in th

Abstract (sommario):

Mesenchymal cell migration and neurite outgrowth are mediated in part by binding of cell surface beta 1,4-galactosyltransferase (GalTase) to N-linked oligosaccharides within the E8 domain of laminin. In this study, we determined whether cell surface GalTase functions during neural crest cell migration and neural development in vivo using antibodies raised against affinity-purified chicken serum GalTase. The antibodies specifically recognized two embryonic proteins of 77 and 67 kD, both of which express GalTase activity. The antibodies also immunoprecipitated and inhibited chick embryo GalTase

Abstract (sommario):

Întegrins coordinate spatial signaling events essential for cell polarity and directed migration. Such signals from α4 integrins regulate cell migration in development and in leukocyte trafficking. Here, we report that efficient α4-mediated migration requires spatial control of α4 phosphorylation by protein kinase A, and hence localized inhibition of binding of the signaling adaptor, paxillin, to the integrin. In migrating cells, phosphorylated α4 accumulated along the leading edge. Blocking α4 phosphorylation by mutagenesis or by inhibition of protein kinase A drastically reduced α4-dependen

Abstract (sommario):

Migrating embryonic cells have high levels of cell surface galactosyltransferase (GalTase) activity. It has been proposed that GalTase participates during migration by recognizing and binding to terminal N-acetylglucosamine (GlcNAc) residues on glycoconjugates within the extracellular matrix (Shur, B. D., 1982, Dev. Biol. 91:149-162). We tested this hypothesis using migrating neural crest cells as an in vitro model system. Cell surface GalTase activity was perturbed using three independent sets of reagents, and the effects on cell migration were analyzed by time-lapse microphotography. The Gal

Abstract (sommario):

Cell migrations are found throughout the animal kingdom and are among the most dramatic and complex of cellular behaviors. Historically, the mechanics of cell migration have been studied primarily in vitro, where cells can be readily viewed and manipulated. However, genetic approaches in relatively simple model organisms are yielding additional insights into the molecular mechanisms underlying cell movements and their regulation during development. This review will focus on these simple model systems where we understand some of the signaling and receptor molecules that stimulate and guide cell

Abstract (sommario):

Collective cell migration is crucial for tissue remodeling and cancer invasion. A RhoA-targeting guanine nucleotide exchange factor, Solo, localizes to the cell–cell contact sites in collectively migrating cells and acts as a brake for collective cell migration via promoting the RhoA-ROCK pathway and regulating the keratin-8/keratin-18 networks.

Abstract (sommario):

Cell migration is essential for development, but its deregulation causes metastasis. The Scar/WAVE complex is absolutely required for lamellipodia and is a key effector in cell migration, but its regulation in vivo is enigmatic. Lamellipodin (Lpd) controls lamellipodium formation through an unknown mechanism. Here, we report that Lpd directly binds active Rac, which regulates a direct interaction between Lpd and the Scar/WAVE complex via Abi. Consequently, Lpd controls lamellipodium size, cell migration speed, and persistence via Scar/WAVE in vitro. Moreover, Lpd knockout mice display defectiv

Abstract (sommario):

Abstract The ability of cells to migrate is a fundamental physiological process involved in embryonic development, tissue homeostasis, immune surveillance and wound healing. In order for cells to migrate, they must interact with their environment using adhesion receptors, such as integrins, and form specialized adhesion complexes that mediate responses to different extracellular cues. In this review, we discuss the role of integrin adhesion complexes (IACs) in cell migration, highlighting the layers of regulation that are involved, including intracellular signalling cascades, mechanosensing an
