The urokinase plasminogen activator system: a target for anti-cancer therapy

Ulisse, Salvatore, Baldini, Enke, Sorrenti, Salvatore, D'Armiento, Massimino·2009·Current Cancer Drug Targets

Abstract

The urokinase plasminogen activator (uPA) system (uPAS) consists of the uPA, its cognate receptor (uPAR) and two specific inhibitors, the plasminogen activator inhibitor 1 (PAI-1) and 2 (PAI-2). The uPA converts the proenzyme plasminogen in the serine protease plasmin, involved in a number of physiopathological processes requiring basement membrane (BM) and/or extracellular matrix (ECM) remodelling, including tumor progression and metastasis. Data accumulated over the past years have made increasingly clear that the uPAS has a multifunctional task in the neoplastic evolution, affecting tumor angiogenesis, malignant cell proliferation, adhesion and migration, intravasation and growth at the metastatic site. In agreement with their role in cancer progression and metastasis, an increased expression of uPA, uPAR, and PAI-1 has been documented in several malignant tumors, and a positive correlation between the levels of one or more uPAS members and a poor prognosis has been frequently reported. This is particularly evident in breast cancer, for which uPA has been demonstrated to be the most potent independent prognostic factor described to date. The involvement of the uPAS in cancer progression identifies its components as suitable targets for anti-cancer therapy. Several therapeutical approaches aimed at inhibiting the uPA/uPAR functions have been shown to possess anti-tumor effects in xenograft models, including selective inhibitors of uPA activity, antagonist peptides, monoclonal antibodies able to prevent uPA binding to uPAR and gene therapy techniques silencing uPA/uPAR expression. All these strategies, however, although promising, need definitive confirmation in humans as, up to now, only few uPA inhibitors entered clinical trial.

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.
