Urokinase and urokinase receptor: A paracrine/autocrine system regulating cell migration and invasiveness

Blasi, Francesco·1993·BioEssays

Abstract

Urokinase and its receptor are essential components of the cell migration machinery, providing an inducible, transient and localized cell surface proteolytic activity. This activity has been shown to be required in normal and pathological forms of cellular invasiveness (i.e. in several embryonic developmental processes, during inflammatory responses and cancer metastasis and spreading). It represents one of the best known of the protcolytic systems which are currently under investigation in this field. The urokinase receptor allows a continuous regulation of the proteolytic activity at cell contacts, utilizing the different localization of urokinase and its inhibitors. The receptor, in fact, in addition to focusing the enzymatic activity at focal and cell‐cell contacts, also regulates it by internalizing and degrading only the inhibited form of urokinase. Internalized receptor releases the ligands to the lysosomes and recycles back to surface. In this way, the proteolytically active areas of the cell surface can be continuously monitored for their activity and their location modified. The cell can thus coordinate its migration efforts with a step‐wise modification of the proteolytic activity‐map of the cell surface. The urokinase cycle can be supported by one individual cell (autocrine) or by two or more cells. In the latter case, complementation and synergism of urokinase and its receptor are found.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
