The extracellular matrix: A dynamic niche in cancer progression

Abstract: The local microenvironment, or niche, of a cancer cell plays important roles in cancer development. A major component of the niche is the extracellular matrix (ECM), a complex network of macromolecules with distinctive physical, biochemical, and biomechanical properties. Although tightly controlled during embryonic development and organ homeostasis, the ECM is commonly deregulated and becomes disorganized in diseases such as cancer. Abnormal ECM affects cancer progression by directly promoting cellular transfo… Show more

“…These findings likely reflect the complexity in composition of ECM and the signaling pathways in response to ECM. Interference of other integrin receptors and kinases individually and in combination, such as integrin α6 (major receptors for laminin), is still needed to determine the role of each individual ECM and its responsive cellular signaling molecules in the activation of HOTAIR expression (Kenny et al ., 2007b; Lee et al ., 2007; Lu et al ., 2012; Weaver et al ., 1997; Ziober et al ., 1999). More importantly, our results indicate that HOTAIR expression is required for invasive growth of Claudin‐low breast cancer cells, particularly cell viability (Fig.…”

“…Le microenvironnement tumoral peut se définir comme l'ensemble des facteurs moléculaires, cellulaires et tissulaires capables d'influencer ou d'être influencés par les cellules tumorales [40] ( §). Au niveau tissulaire, la MEC, les vaisseaux sanguins et lymphatiques, ainsi que l'hypoxie, jouent des rôles importants dans le développement de tumeurs primaires et leur dissémination [6][7][8]. Au niveau cellulaire, trois catégories de protagonistes peuvent être distinguées en fonction de leur origine et de leurs fonctions [2] : les cellules vasculaires angiogéniques -cellules endothéliales et péricytes ; les cellules fibroblastiques associées aux cancers, comprenant les fibroblastes (CAF pour cancer associated fibroblasts) [41] ( §), mais aussi les adipocytes ou des cellules mésenchymateuses moins diffé-renciées [42] …”

“…Ces changements sont caractérisés par un remodelage important de la MEC [7,45] ( §), la formation de nouveaux vaisseaux sanguins (angiogenèse) [6] et lymphatiques [9] irrigant la tumeur, et l'infiltration d'un grand nombre de cellules immunitaires. Les cellules néoplasiques produisent une panoplie de facteurs (cytokines, chimiokines, etc.)…”
