Invadopodia (original) (raw)
Invadopodia are actin-rich protrusions of the plasma membrane that are associated with degradation of the extracellular matrix in cancer invasiveness and metastasis. Very similar to podosomes, invadopodia are found in invasive cancer cells and are important for their ability to invade through the extracellular matrix, especially in cancer cell extravasation.Invadopodia are generally visualized by the holes they create in ECM (fibronectin, collagen etc.)-coated plates, in combination with immunohistochemistry for the invadopodia localizing proteins such as cortactin, actin, Tks5 etc. Invadopodia can also be used as a marker to quantify the invasiveness of cancer cell lines in vitro using a hyaluronic acid hydrogel assay.

| dbo:abstract | Invadopodia jsou výčnělky buněčné membrány některých buněk. Jsou bohaté na aktinová filamenta a jsou v kontaktu s bílkovinami extracelulární matrix. V invadipodiích je zaznamenávána vysoká míra proteolytického rozkladu a zároveň se zde odehrává čilá buněčná signalizace. Na druhou stranu jsou invadipodia mnohdy pozorována u metastazujících nádorových buněk. Do jisté míry se invadipodia podobají vytvářeným normálními buňkami, jež pouze potřebují překročit tělní bariéry (např. makrofágy a monocyty vystupující z cév). Podozomy jsou však pouze časově omezené a neúčastní se degradace mimobuněčné hmoty. V některých případech (např. u některých rakoviny prsu) je schopnost tvořit invadipodia přímo spojena s jejich rakovinotvorným chováním.
