Basement membrane stiffness determines metastases formation

چکیده
The basement membrane (BM) is a special type of extracellular matrix and presents the major barrier cancer cells have to overcome multiple times form metastases. Here we show that BM stiffness determinant metastases formation in several tissues identify netrin-4 (Net4) as key regulator stiffness. Mechanistically, our biophysical functional analyses combination with mathematical simulations Net4 softens mechanical properties native BMs by opening laminin node complexes, decreasing cell potential transmigrate this despite creating bigger pores. Our results therefore reveal dominant over pore size, ‘normal’ determine patient survival independent cancer-mediated alterations. Thus, identifying individual protein levels within metastatic organs may define even before tumour formation. ratio molecules determines stiffness, such more Net4, softer BM, thereby invasion activity. shown be than size regulating invasion, metastasis survival. This now known affected laminin, leading membranes.

Evaluation of Basement Membrane Formation on Bruch’s Membrane Implants
The long-term success of an implant may be dependent on the production of a stable basement membrane and it may be desirable to reproduce the structure of healthy Bruch’s membrane. We hypothesise that the substrate surface chemistry will influence RPE extracellular matrix (ECM) production. The aim of this work was to investigate the distribution of ECM proteins produced by primary human RPE cel...
متن کاملBasement membrane.
Basement membrane has attracted less attention than the other components of connective tissue. But, like the other extracellular fibres and matrix materials, it can profoundly influence both the structure and function of advanced life forms. Usually taking the shape of thin, structureless cementing material between epithelial and connective tissue, basement membranes are widely distributed thro...

We report a case of struma ovarii with hyperthyroidism and elevated serum concentrations of type IV collagen and laminin. Circulating levels of type IV collagen and laminin were measured using specific radioimmunoassays (RIAs) for 7S collagen and the P-1 fragment of laminin, and the basement membrane components in the tumor were investigated by immunohistochemical analysis. Strong immunohistoch...
متن کاملPossible Diverse Roles of Fukutin: More Than Basement Membrane Formation?
Fukutin is a gene responsible for Fukuyama-type congenital muscular dystrophy (FCMD) (Kobayashi et al. 1998). FCMD is associated with ocular and central nervous system (CNS) malformation characterized by cobblestone lissencephaly (Fukuyama et al. 1960; Osawa et al. 1997), and is included in -dystroglycanopathy, one of the groups of muscular dystrophy. -dystroglycan (-DG) is one of the compon...
