Therapeutic induction of angiogenesis is a potential treatment for chronic ischemia. Heparan sulfate proteoglycans are known to play an important role by their interactions with proangiogenic growth factors such as vascular endothelial factor (VEGF). Low molecular weight fucoidan (LMWF), sulfated polysaccharide from brown seaweeds that mimic some biological activities heparin, has been shown recently promote revascularization in rat critical hindlimb In this report, we first used cultured...
The causes of transient hypocalcemia after thyroid surgery are not fully understood. In 95 consecutive patients undergoing total thyroidectomy (n = 30), subtotal 14), or hemithyroidectomy 51), we serially measured calcium, parathyroid hormone (PTH), and proteins before 6, 24, 48, 72, 96 hours surgery, calculated the corresponding ionized calcium levels. whole population, there was a statistically significant decrease PTH, at nearly every time blood withdrawal, when compared with preoperative...
Nephrotic syndrome in minimal change lipoid nephrosis and focal segmental glomerulosclerosis may be due to alteration of glomerular anionic sites by a lymphokine. Six adults with nephrotic who were resistant treatment corticosteroids immunosuppressants treated cyclosporin A. In three patients had been for 3.5 23 years proteinuria resolved within 12 42 days. Subsequently, these became dependent on four six mean (SD) 24 hour urinary protein decreased from 14.7 (8.4) g 3.6 (0.6) 20 25 days,...
SUMMARY A study of hypothalamo‐pituitary function was carried out in chronic alcoholic women aged 29–66 years, with pancreatitis or cirrhosis the liver. Amenorrhoea present most them (67%). The hormonal investigation included assessment basal plasma steroids, gonadotrophin and prolactin values, followed by an anterior pituitary test. Clomiphene stimulation and/or hCG tests were performed. subjects divided into four groups according to their oestrogen status on one hand, baseline...
Abstract The CC-chemokine regulated on activation, normal T-cell expressed, and presumably secreted (RANTES)/CCL5 mediates its biological activities through activation of G protein–coupled receptors, CCR1, CCR3, or CCR5, binds to glycosaminoglycans. This study was undertaken investigate whether this chemokine is involved in hepatoma cell migration invasion modulate these effects vitro by the use glycosaminoglycan mimetics. We show that human Huh7 Hep3B cells express RANTES/CCL5 receptor CCR1...
The existence of multiple VEGF-A isoforms raised the possibility that they may have distinct functions in tumor growth. We previously published VEGF189 and VEGF165 contribute to breast cancer progression angiogenesis, but induced most rapid uptake. Since has been described as a survival factor for cells, we questioned here effects on survival/apoptosis MDA-MB-231 cells. used clones which overexpress (V189) or (V165) compared them control one (cV). Overexpression resulted increased cell...
We have recently reported that the CXC-chemokine stromal cell-derived factor-1 (SDF-1)/CXCL12 induces proliferation, migration, and invasion of Huh7 human hepatoma cells through its G-protein-coupled receptor CXCR4 glycosaminoglycans (GAGs) are involved in these events. Here, we demonstrate by surface plasmon resonance chemokine binds to GAG mimetics obtained grafting carboxylate, sulfate or acetate groups onto a dextran backbone. also chemically modified dextrans inhibit...
