neoplasm metastasis/protease

We present here the results from MS peptide profiling experiments of prostate carcinoma patients and controls with a specific focus on protease activity-related protein fragments. After purification with surface-active magnetic beads, MALDI-TOF profiling experiments were performed on tryptic digests

Protease-activated receptor-2 (PAR-2) is a G protein-coupled receptor that functions as a cell-surface sensor for coagulation factors and other proteases associated with the tumour microenvironment. Pancreatic cancer cells express high levels of PAR-2 and activation of PAR-2 may induce their

The secretory leukocyte protease inhibitor (SLPI) can attenuate the host proinflammatory response by blocking nuclear factor kappaB (NF-kappaB)-mediated tumor necrosis factor alpha (TNF-alpha) production in macrophages. We have previously shown that highly metastatic human and mouse carcinoma cells,

BACKGROUND The potential of secretory leukocyte protease inhibitor (SLPI) as a biomarker for colorectal cancer was studied. A prospective, randomized, controlled, clinical trial was conducted in 2013 and 2014 to confirm whether the expression of SLPI correlates with prognosis and metastasis in

The development of effective therapies inhibiting prostate cancer progression and metastasis may substantially impact prostate cancer mortality and potentially reduce the rates of invasive treatments by enhancing the safety of active surveillance strategies. Hepsin (HPN) is a cell surface serine

The presence of the human epidermal SH-protease inhibitor in human tumours of different types was examined using double radial immunodiffusion against specific antisera to the inhibitor. The immunoreactive protein was found to be present in all the tumours with criteria of epidermoid carcinoma

We examined the inhibitory effect of a serine protease inhibitor, FOY-305, on the invasion and metastasis of human pancreatic cancers. The in vitro matrigel invasion assay showed that the invasiveness of Capan-1 human pancreatic cancer cells was inhibited by FOY-305 treatment in a dose-dependent

Accumulating evidence suggests that protease receptors and their cognate protease ligands play important roles in cell-signaling events that regulate cell adhesion and migration in inflammation as well as tumor invasion and metastasis. Tissue factor (TF), the cell surface receptor for the serine

OBJECTIVE Protease-activated receptor-1 (PAR-1) is a G-protein-coupled receptor that contributes to multiple signal transduction pathways. Although the functions of PAR-1 in many normal cells, such as platelets and astrocytes, have been well studied, its roles in cancer progression and metastasis

The human ovarian cancer cell line OV-MZ-19, established from a patient with cystadenocarcinoma of the ovary, expressing thrombomodulin (TM), a cell surface receptor for the serine protease thrombin, interacts with monoclonal and polyclonal antibodies having different specificity for TM. These

We have examined the nature of biochemical degradation of an isolated basement membrane matrix (bovine lens capsule) using different methodologies. The first strategy was quantitation of the release of surface-bound 125I and a second the documentation by SDS-PAGE of the appearance of putative

OBJECTIVE A great deal of breast cancer research has been devoted to the search for new prognostic and predictive markers which could, on the one hand, enable a more precise identification of patients at high risk of recurrence and, on the other hand, predict the response of each individual patient

We tested how adjuvants effect in a cancer vaccine model using an epitope derived from an autoactivation loop of membrane-type protease serine protease 14 (PRSS14; loop metavaccine) in mouse mammary tumor virus (MMTV)-polyoma middle tumor-antigen (PyMT) system and in 2 other orthotopic mouse

Thrombin-treated tumor cells induce a metastatic phenotype in experimental pulmonary murine metastasis. Thrombin binds to a unique protease-activated receptor (PAR-1) that requires N-terminal proteolytic cleavage for activation by its tethered end. A 14-mer thrombin receptor activation peptide

Tissue factor (TF) is a transmembrane glycoprotein that complexes with factor VIIa to initiate blood coagulation. We previously reported that expression of high levels of TF in a human melanoma cell line promotes metastasis. Both the cytoplasmic domain of TF and its extracellular domain complexed
