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. Herein, we sought to decipher the effect of KAN0438757 on proliferation, migration, DNA damage, and programmed

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 +/-

The stereotyped distribution of identified neurons and glial cells in the leech nervous system is the product of stereotyped cell migrations and rearrangements during embryogenesis.

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.

AbstractFibrillar collagen is an abundant extracellular matrix (ECM) component of interstitial tissues which supports the structure of many organs, including the skin and breast. Many different physiological processes, but also pathological processes such as metastatic cancer invasion, involve interstitial cell migration. Often, cell movement takes place through small ECM gaps and pores and depends upon the ability of the cell and its stiff nucleus to deform. Such nuclear deformation during cell migration may impact nuclear integrity, such as of chromatin or the nuclear envelope, and therefore

These components are differentially distributed within a cell, and thus the coordination between tractions and mechanotransduction (i.e, RhoA and Rac1 activities) must be implemented at a precise spatial and temporal order to achieve optimized, directed cell migration [4,5].

Metastasis is the cause of 90% of cancer-related deaths and yet the precise mechanism of metastasis is poorly understood[1]. To metastasize, cells break free from the primary tumor, migrate through the surrounding tissue, and enter the vascular system to move to a secondary site. To migrate through the stroma, cell can both degrade the tissue and use physical force to move the tissue from its path. However, the relative roles of matrix degradation and cellular force are not well-understood. Previous work has shown that as cell move through the matrix, they create channels that other cells can

Abstract (sommario):
The capability of cancer cells to resist to anoikis, migrate and invade surrounding tissues is associated with high metastatic potential and advanced stage of cancers. Recently, caveolin-1 (Cav-1) protein has garnered increased attention in implicating the aggressive behavior of cancer cells. We demonstrate herein that nitric oxide and hydrogen peroxide play a role in inhibiting anoikis process of lung cancer cells via caveolin-1 dependent mechanism. The Cav-1 function in inhibition of anoikis was demonstrated to be cause through Mcl-1 dependent mechanism. The present study demonstrated that C
