Abstract:
BACKGROUND: The plasminogen urokinase activation system consists of urokinase plasminogen activator (uPA), its receptor uPAR, and plasminogen activator inhibitor type 1 (PAI-1), which are considered to have a relationship with cancer aggressiveness. Several studies have found correlations between HER2 mRNA and uPAR in disseminated tumor cells (DTCs) in breast cancer patients. They are associated with a more aggressive primary tumor phenotype and recurrence/metastasis. OBJECTIVE: This study aims to determine the relationship between the expression of urokinase-type plasminogen activator recepto

Cathepsin B (CB) is a thiol-stimulated protease implicated in cancer invasion and metastasis. Other proteases involved in cancer spread such as urokinase-type plasminogen activator (uPA) and cathepsin D have previously been shown to be prognostic markers in breast cancer. CB was assayed by ELISA in 193 patients with primary breast cancer. CB levels were significantly higher in both primary and metastatic breast tumors than in fibroadenomas (p=0.0001). In the primary carcinomas, CB levels showed no significant correlation with either nodal status, tumor size or estrogen receptor (ER) status. Pa

S100P protein in human breast cancer cells is associated with reduced patient survival and, in a model system of metastasis, it confers a metastatic phenotype upon benign mammary tumour cells. S100P protein possesses a C-terminal lysine residue. Using a multiwell in vitro assay, S100P is now shown for the first time to exhibit a strong, C-terminal lysine-dependent activation of tissue plasminogen activator (tPA), but not of urokinase-catalysed plasminogen activation. The presence of 10 μM calcium ions stimulates tPA activation of plasminogen 2-fold in an S100P-dependent manner. S100P physicall

Abstract Background: For optimum management of patients with cancer, accurate assessment of prognosis is essential. The primary determinant of outcome in malignancy is the formation of distant metastases. Urokinase plasminogen activator (uPA) is a serine protease causally involved in invasion and metastasis. Content: Data from model systems show that uPA is unequivocally involved in cancer dissemination. Consistent with its role in metastasis, multiple independent groups have shown that high uPA concentrations in primary breast cancers correlate with poor prognosis. For determining outcome, th

Urokinase-type plasminogen activator (uPA) is a serine protease that is causally involved in cancer progression, especially invasion and metastasis. Multiple studies have shown that breast cancer patients whose primary cancer contains high levels of uPA have a significantly worse outcome than patients with low levels. As a prognostic marker for breast cancer the information supplied by uPA is both independent of traditionally used factors and significant in the important subgroup of axillary-node patients.

Here we evaluate cell surface plasminogen binding in human breast cancer. In a xenograft model for aggressive, triple-negative human breast cancer, tumor cells harvested from orthotopic mammary fat pad (mfp) tumors of the invasive human breast cancer line, MDA-MB-231, exhibit dramatic increases in tumor growth and lung and lymph node metastases, compared to parental cells.

Abstract:
Invasion and metastasis are crucial steps in breast cancer for patient's survival. Recent studies suggest the involvement of loss of DNA methylation resulting in the activation of prometastatic genes, such as uPA and heparanase, during metastasis progression. Also, global DNA hypomethylation and regional DNA hypermethylation are associated with tumorigenesis. Methylated CpG binding protein 2 (MBD2) binds to methylated DNA and demethylates it. Early growth response 1 (EGR1) is also implicated in metastasis and DNA demethylation. We show in this study that MBD2 expression in breast cancer cell l
