Pleiotrophin Activates cMet- and mTORC1-Dependent Protein Synthesis through PTPRZ1-The Role of αβ Integrin.

Pleiotrophin (PTN) is a secreted factor that regulates endothelial cell migration through protein tyrosine phosphatase receptor zeta 1 (PTPRZ1) and αβ integrin. Genetic deletion of results in enhanced endothelial cell proliferation and migration, due to the decreased expression of β integrin and the subsequent, enhanced cMet phosphorylation. In the present study, we investigated the effect of PTN and PTPRZ1 on activating the mTORC1 kinase and protein synthesis and identified part of the implicated signaling pathway in endothelial cells.

Genetic deletion or tyrosine phosphatase inhibition of PTPRZ1 activates c-Met to up-regulate angiogenesis and lung adenocarcinoma growth.

Protein tyrosine phosphatase receptor zeta 1 (PTPRZ1) is a transmembrane tyrosine phosphatase (TP) expressed in endothelial cells and required for stimulation of cell migration by vascular endothelial growth factor A (VEGFA ) and pleiotrophin (PTN). It is also over or under-expressed in various tumor types. In this study, we used genetically engineered Ptprz1 and Ptprz1 mice to study mechanistic aspects of PTPRZ1 involvement in angiogenesis and investigate its role in lung adenocarcinoma (LUAD) growth.

A non-interventional switch study in adult patients with asthma or COPD on clinical effectiveness of salmeterol/fluticasone Easyhaler in routine clinical practice.

Background: Selection of the most appropriate device for a switch from one inhaler to an equivalent product is known to have a major impact on clinical outcomes in patients with asthma or chronic obstructive pulmonary disease (COPD). Salmeterol/fluticasone propionate (S/F) Easyhaler has been demonstrated to be therapeutically equivalent with a reference product. However, no data on real-life effectiveness are currently available for patients switching to S/F Easyhaler from another S/F inhaler.

Gemcitabine combined with oxaliplatin in pretreated patients with malignant pleural mesothelioma: an observational study.

Background: The aim of this study was to investigate the efficacy and safety of oxaliplatin +/- gemcitabine in patients with diffuse malignant pleural mesothelioma (MPM) pretreated with pemetrexed.

Methods: The study enrolled consecutive patients with relapsed MPM, all of them pretreated with a platin-pemetrexed-based chemotherapy. Oxaliplatin 80 mg/m2 was administered as monotherapy or in combination with gemcitabine 1000 mg/m2 given on day 1 and 8.

Doppler-derived parameters of diastolic left ventricular function in preterm infants with a birth weight <1500 g: reference values and differences to term infants.

Transmitral flow parameters in preterm and term infants were compared in order to study differences in signal expression and temporal dynamics of left ventricular diastolic function. In 63 preterm infants between 26 and 33 weeks of gestation and 102 term infants, a Doppler survey was performed during 6 months after birth. Early and atrial filling-time velocity integrals and peak velocities were significantly lower in the preterm neonates.
