The Vegf Pathway in Patients with Pancreatic Neuroendocrine Tumors: Efficacy of Everolimus by Baseline Marker Level, and Prognostic and Predictive Effect Analyses from Radiant-3
ABSTRACT Background RADIANT-3 was a phase III study investigating the effect of the mammalian target of rapamycin inhibitor everolimus on progression-free survival (PFS) in patients with advanced pancreatic neuroendocrine tumors (pNET; Yao et al, NEJM, 2011). Everolimus significantly improved PFS compared with placebo (11 vs 4.6 months, P Methods Baseline plasma levels of VEGF-A, PlGF, sVEGFR1, and sVEGFR2 were determined by ELISA using multiplexed MSD platform. The optimal cutoffs for these markers were explored using the “survival tree analysis” method. Interaction of treatment and baseline marker status ( Results PFS was significantly improved to a similar extent in patients receiving e…
The rxr agonist bexarotene in combination with rosuvastatin inhibits angiotensin-ii induced abdominal aortic aneurysm formation in apoliprotein -e-knockout mice
Effect of chondroitin sulphate on synovitis of knee osteoarthritic patients.
Abstract Objective To evaluate by ultrasonography the effect of chondroitin sulfate (CS) on synovitis in patients with knee osteoarthritis (KOA). To collaborate in the understanding of the biochemical mechanisms involved in the synovial inflammation process. Methods Randomized, single-blind, controlled trial involving 70 patients with primary KOA treated for 6 months with CS or acetaminophen (ACT). Evaluation of KOA status at baseline, 6 weeks, 3 and 6 months included: ultrasonography to assess synovitis (following the OMERACT expertise group definition), visual analogue scale and Lequesne index to measure pain and function, and ELISA to quantify inflammatory mediators in serum and synovial…
Synergistic antiangiogenic activity of bexarotene in combination with rosuvastatin by targeting ang-ii-mediated akt/mtor/p70s6k signaling pathway
Contributions of ACE and mast cell chymase to endogenous angiotensin II generation and leucocyte recruitment in vivo
Aims In vitro studies suggest that mast cell chymase (MCP) is more important than angiotensin-converting enzyme (ACE) for generating angiotensin II (Ang II) within the cardiovascular system. We investigated in vivo the relative contributions of ACE and MCP to leucocyte recruitment induced by endogenously generated Ang II. Methods and results Exposure of the murine cremasteric microcirculation of C57BL/6 mice to Ang I (100 nM for 4 h) induced leucocyte–endothelium interactions. Either losartan (an Ang II receptor-1 antagonist, AT1) or enalapril (an ACE inhibitor), but not chymostatin (a chymase inhibitor), inhibited Ang I-induced responses. Mast cell degranulation with compound 48/80 (CMP48/…
Combined treatment with bexarotene and rosuvastatin reduces angiotensin-II-induced abdominal aortic aneurysm in apoE−/−mice and angiogenesis
Background and Purpose Abdominal aortic aneurysm (AAA) is a degenerative vascular disease associated with angiogenesis. Bexarotene is a retinoid X receptor (RXR) ligand with anti-angiogenic activity. Statins also exert anti-angiogenic activity and activate PPARs. Because RXR ligands form permissive heterodimers with PPARs and a single anti-angiogenic drug may not be sufficient to combat the wide array of angiogenic factors produced during AAA, we evaluated the effect of combined low doses of bexarotene and rosuvastatin in a mouse model of AAA.
Efecto del condroitín sulfato en la sinovitis de pacientes con artrosis de rodilla
Resumen Objetivo Evaluar mediante ecografia el efecto del condroitin sulfato (CS) en la sinovitis de pacientes con artrosis (OA) de rodilla, y colaborar en el conocimiento de los mecanismos bioquimicos involucrados en la inflamacion sinovial. Metodos Estudio controlado, aleatorizado, ciego simple de 70 pacientes con OA de rodilla tratados durante 6 meses con CS o paracetamol (PCT). Los pacientes fueron visitados a tiempo basal, a las 6 semanas, y a los 3 y 6 meses para valorar el estado de su OA segun los siguientes parametros: sinovitis evaluada mediante ecografia (segun definicion de expertos OMERACT); dolor y funcion, mediante la escala visual analogica y el indice de Lequesne; y concent…
Functional role of endothelial CXCL16/CXCR6-platelet-leucocyte axis in angiotensin II-associated metabolic disorders.
Aims Angiotensin-II (Ang-II) is the main effector peptide of the renin-angiotensin system (RAS) and promotes leucocyte adhesion to the stimulated endothelium. Because RAS activation and Ang-II signalling are implicated in metabolic syndrome (MS) and abdominal aortic aneurysm (AAA), we investigated the effect of Ang-II on CXCL16 arterial expression, the underlying mechanisms, and the functional role of the CXCL16/CXCR6 axis in these cardiometabolic disorders. Methods and results Results from in vitro chamber assays revealed that CXCL16 neutralization significantly inhibited mononuclear leucocyte adhesion to arterial but not to venous endothelial cells. Flow cytometry and immunofluorescence s…
El ratón deficiente en apolipoproteína E, un modelo traslacional para el estudio de la aterosclerosis
Resumen Introduccion La aterosclerosis es una de las principales causas de morbimortalidad en paises desarrollados que presenta varias similitudes histopatologicas con la inflamacion cronica. Los ratones deficientes en apolipoproteina E (apoE -/− ) son ampliamente utilizados en el estudio de los mecanismos implicados en el inicio y el progreso de las lesiones ateroscleroticas. Objetivo Evaluar el impacto en la formacion de la placa de ateroma de una dieta aterogenica en el raton apoE -/− . Material y metodos Ratones apoE -/− de 2 meses de edad fueron sometidos o no a una dieta hipercolesterolemica (10,8% de grasa, 0,75% en colesterol) durante 2 meses adicionales. Se determino el perfil lipi…
