poison ligand-targeted (LTTs) are artificial molecules that consist of a targeting component associated with the toxins that induce cell death after binding targets LTT. targeting bispecific allows for the simultaneous targeting of two receptors. In this review, we mostly focus on epidermal growth factor receptor (EGFR) as a target. We discuss the development and testing of LTT bispecific targeting EGFR and urokinase-type plasminogen activator receptor (Upar) as two attractive targets involved in tumor growth and in the regulation of the tumor microvasculature in solid tumors. In vitro and mouse xenograft studies have demonstrated that EGFR-targeted bispecific angiotoxin (eBAT) effective against human solid tumors. Studies have shown that eBAT dog is safe and effective against canine hemangiosarcoma, which are physiologically similar to human angiosarcoma.
Finding the right dose strategy and sequencing eBAT administration, in combination with other therapies, among the factors important for the future direction. Together, the data suggest that stem cells eBAT cancer targets, may have a role in inhibiting tumor blood vessels, human, and bispecific conformations that may have a role in reducing the toxicity of the oncologic comparative trials in dogs. The urokinase plasminogen activator and its receptor (uPA / Upar) is a biomarker for metastasis, particularly in triple-negative breast cancer.
We set up an anti-mitotic N-alkylisatin (N-AI) -loaded liposomes functionalized with uPA / Upar targeting ligand, plasminogen activator inhibitor type 2 (PAI-2 / SerpinB2), and rated liposome uptake in vitro and in vivo. receptor dependent uptake of liposome-functionalized PAI-2 was significantly higher in the uPA / Upar overexpressing MDA-MB-231 breast cancer cells is relatively low Upar / Upar expressing MCF-7 breast cancer cells. Furthermore, N-AI cytotoxicity enhanced by receptor-dependent manner.
In vivo, PAI-2 N-AI liposomes have a plasma half-life of 5.82 h and showed increased accumulation at the primary tumor site in the MDA-MB-231 BALB / c-Fox1nu / Ausb mouse orthotopic xenograft model, relative to non-functionalized liposome , up to 6 hours post injection. These findings support the further development of the N-AI-loaded liposomes PAI-2-enabled for breast cancer uPA / Upar-positive, especially against triple-negative breast cancer, the prognosis is poor and treatment is limited.

Soluble urokinase plasminogen activator receptor as a prognostic biomarker for long-term acute coronary syndrome
Objective: The aim of our study was to analyze the long-term prognostic value soluble urokinase plasminogen activator receptor (Supar) in the setting of acute coronary syndromes (ACS) .Methods: We included 340 patients with ACS undergoing coronary angiography and plasma concentrations were measured Supar. Patients were classified into Supar low concentrations (<2.6 ng / mL) and high Supar concentration (≥2.6 ng / mL) and long-term events are evaluated.
Supar rated prognostic value beyond the clinical model that included age, GRACE score, estimated glomerular filtration rate, cardiac troponin-I peak and left ventricular ejection fraction <40% .Results: Higher concentrations Supar associated with an increased prevalence of cardiovascular risk factors.
Description: Urokinase (peptidolytic) (EC 3.4.21.73) is a serine protease, an inactive form (zymogen) of the serine protease plasminogen. Activation of plasmin triggers a proteolytic cascade reaction, which in turn participates in thrombolysis or extracellular matrix degradation, implicated in vascular disease and cancer-related research[1].
Description: A competitive ELISA for quantitative measurement of Human Urokinase in samples from blood, plasma, serum, cell culture supernatant and other biological fluids. This is a high quality ELISA kit developped for optimal performance with samples from the particular species.

After multivariate adjustment, Supar ≥2.6 ng / mL were independently associated with an increased risk of all-cause mortality (HR 2.3; 95% CI 1.2 to 4.4; p = 0.017), major adverse cardiovascular events (MACE) ( HR 1.7; 95% CI 1.1 to 2.5; p = 0.020) and heart failure (HR 4.1; 95% CI 1.3 to 12.6; p = 0.015), but not with myocardial infarction , For long-term all-cause mortality significant increase of reclassification and discrimination Supar look after addition to the clinical model.
