TLDR
Cancer cells possess a broad spectrum of migration and invasion mechanisms and learning more about the cellular and molecular basis of these different migration/invasion programmes will help to understand how cancer cells disseminate and lead to new treatment strategies.Abstract:
Cancer cells possess a broad spectrum of migration and invasion mechanisms. These include both individual and collective cell-migration strategies. Cancer therapeutics that are designed to target adhesion receptors or proteases have not proven to be effective in slowing tumour progression in clinical trials — this might be due to the fact that cancer cells can modify their migration mechanisms in response to different conditions. Learning more about the cellular and molecular basis of these different migration/invasion programmes will help us to understand how cancer cells disseminate and lead to new treatment strategies.read more

Cell migration: integrating signals from front to back.
Anne J. Ridley,Martin A. Schwartz,Keith Burridge,Richard A. Firtel,Mark H. Ginsberg,Gary G. Borisy,J. Thomas Parsons,Alan Rick Horwitz +7 more
TL;DR: The mechanisms underlying the major steps of migration and the signaling pathways that regulate them are described, and recent advances investigating the nature of polarity in migrating cells and the pathways that establish it are outlined.

Cancer Metastasis: Building a Framework
Gaorav P. Gupta,Joan Massagué +1 more
TL;DR: Understanding of the origins and nature of cancer metastasis and the selection of traits that are advantageous to cancer cells is promoted.
Journal ArticleDOI
Tumor Metastasis: Molecular Insights and Evolving Paradigms
TL;DR: The invasion-metastasis cascade is a multistep cell-biological process that involves dissemination of cancer cells to anatomically distant organ sites and their subsequent adaptation to foreign tissue microenvironments as mentioned in this paper.

Snail, ZEB and bHLH factors in tumour progression: an alliance against the epithelial phenotype?
TL;DR: The identification of Snail, ZEB and some basic helix-loop-helix factors as inducers of epithelial–mesenchymal transition (EMT) and potent repressors of E-cadherin expression has opened new avenues of research with potential clinical implications.
Journal ArticleDOI
The third dimension bridges the gap between cell culture and live tissue
TL;DR: It is believed that 3D cultures will have a strong impact on drug screening and will also decrease the use of laboratory animals, for example, in the context of toxicity assays.

Integrins: Bidirectional, Allosteric Signaling Machines
TL;DR: Current structural and cell biological data suggest models for how integrins transmit signals between their extracellular ligand binding adhesion sites and their cytoplasmic domains, which link to the cytoskeleton and to signal transduction pathways.

Epithelial–mesenchymal transitions in tumour progression
TL;DR: Epithelial–mesenchymal transition provides a new basis for understanding the progression of carcinoma towards dedifferentiated and more malignant states.

Rho, Rac, and Cdc42 GTPases regulate the assembly of multimolecular focal complexes associated with actin stress fibers, lamellipodia, and filopodia
Catherine D. Nobes,Alan Hall +1 more
TL;DR: It is reported here that cdc42, another member of the rho family, triggers the formation of a third type of actin-based structure found at the cell periphery, filopodia, in addition to stress fibers, and rho controls the assembly of focal adhesion complexes.

How Matrix Metalloproteinases Regulate Cell Behavior
Mark D. Sternlicht,Zena Werb +1 more
TL;DR: Recent advances shed light on how the structure and function of the MMPs are related and on how their transcription, secretion, activation, inhibition, localization, and clearance are controlled.
