hTERT promotes cell adhesion and migration independent of telomerase activity.
hTERT, a catalytic component of human telomerase, is undetectable in normal somatic cells but up-regulated in cancer and stem cells where telomere length is maintained by telomerase. Accumulated evidence indicates that hTERT may have noncanonical functions beyond telomerase by regulating the expression of particular genes. However, comprehensive identification of the genes regulated by hTERT is...
متن کاملAdhesion in cell migration.
Adhesive interactions play a central role in cell migration. The regulation of these interactions requires the coordination of a multiplicity of signals, both spatially and temporally. The role of the integrin family has received considerable recent attention. Progress has been made in the elucidation of the mechanisms by which growth factors and other motogenic factors stimulate migration. Maj...
متن کاملEndothelial cell adhesion and migration.
Endothelial cell adhesion and migration is fundamental to a number of physiologic processes, including vascular development and angiogenesis. It has been investigated in a variety of contexts, including tumorigenesis, wound healing, tissue engineering, and biomaterial design. The chemical and mechanical extracellular environments are critical regulators of these processes, affecting integrin-ma...
متن کاملFocal adhesion size uniquely predicts cell migration.
Focal adhesions are large protein complexes organized at the basal surface of cells, which physically connect the extracellular matrix to the cytoskeleton and have long been speculated to mediate cell migration. However, whether clustering of these molecular components into focal adhesions is actually required for these proteins to regulate cell motility is unclear. Here we use quantitative mic...
متن کامل[Mechanisms of cell adhesion and migration].
In order to understand the molecular mechanisms underlying cancer metastasis, it is important to clarify the mechanisms of cell adhesion and cell migration. When epithelial cells start to migrate, cell-cell junctions are first disrupted. During migration, membrane protrusions, such as lamellipodia and filopodia, are observed externally at the cell front, and retraction at the cell rear. In addi...
