The anti-inflammatory, antiangiogenic, anticoagulant, and antiadhesive properties of fucoidans obtained from nine species of brown algae were studied in order to examine the influence of fucoidan origin and composition on their biological activities. All fucoidans inhibited leucocyte recruitment in an inflammation model in rats, and neither the content of(More)
The purpose of this study was to investigate the antiangiogenic and in vivo properties of the recently identified phosphatidylinositol 3-kinase (PI3K)/Akt inhibitor Inositol(1,3,4,5,6) pentakisphosphate [Ins(1,3,4,5,6)P5]. Because activation of the PI3K/Akt pathway is a crucial step in some of the events leading to angiogenesis, the effect of(More)
Sulfated polysaccharides from Laminaria saccharina (new name: Saccharina latissima) brown seaweed show promising activity for the treatment of inflammation, thrombosis, and cancer; yet the molecular mechanisms underlying these properties remain poorly understood. The aim of this work was to characterize, using in vitro and in vivo strategies, the(More)
The aim of the study was to evaluate the activity of the antiangiogenic agent SU-11248 (sunitinib malate, Sutent), alone or in combination with docetaxel. To this end, animals bearing DU-145 human hormone-refractory prostate cancer (HRPC) xenografts were treated with sunitinib (40 mg/kg daily, p.o.), docetaxel (10 or 30 mg/kg/week, i.v.), a combination of(More)
BACKGROUND Galectins have emerged as critical regulators of tumor progression and metastasis, by modulating different biological events including homotypic cell aggregation, apoptosis, migration, angiogenesis and immune escape. Therefore, galectin inhibitors might represent novel therapeutic agents for cancer. MATERIALS AND METHODS A series of structural(More)
Elevated serum or tissue levels of lectin galactoside-binding soluble 3 binding protein (LGALS3BP) have been associated with short survival and development of metastasis in a variety of human cancers. However, the role of LGALS3BP, particularly in the context of tumor–host relationships, is still missing. Here, we show that LGALS3BP knockdown in MDA-MB-231(More)
Galectins, a family of structurally related carbohydrate-binding proteins, contribute to different events associated with cancer biology, including apoptosis, homotypic cell aggregation, angiogenesis and tumor-immune escape. To interfere with galectin-carbohydrate interactions during tumor progression, a current challenge is the design of specific galectin(More)
CRC-associated P53 mutations have not been studied extensively in non-Western countries at relatively low CRC risk. We examined, for the first time, 196 paraffin-embedded CRC cases from Northern Iran for mutations in P53 exons 5-8 using PCR-direct sequencing. P53 status and mutation site/type were correlated with nuclear protein accumulation,(More)
