BACKGROUND Renal cell carcinoma (RCC) is one of the most common types of cancer in urological system worldwide. Recently, the anticancer role of Glucosamine has been studied in many types of cancer. The aim of this study was to investigate the effects of Glucosamine on RCC. METHODS The effects of Glucosamine on RCC cell proliferation and apoptosis were investigated by MTT assay and Annexin V-...

A novel method was developed for production, recovery, and purification of fungal glucosamine. Fungal glucosamine is a good candidate for replacement of glucosamine obtained from shellfish wastes. Mycelium of the Rhizopusoryzae was treated with hot sodium hydroxide solution to obtain the fungal cell wall skeleton. Phosphates were removed from the cell wall by cold dilute sulfuric acid treatment...

Glucosamine is one of the most popular dietary supplements sold in the United States. Most clinical trials have focused on its use in osteoarthritis of the knee. The reported adverse effects have been relatively well studied and are generally uncommon and minor. No significant supplement-drug interactions involving glucosamine have been reported. The National Institutes of Health-sponsored Gluc...

Glucosamine-induced endoplasmic reticulum (ER) stress was recently shown to specifically reduce apolipoprotein B-100 (apoB-100) secretion by enhancing the proteasomal degradation of apoB-100. Here, we examined the mechanisms linking glucosamine-induced ER stress and apoB-lipoprotein biogenesis. Trypsin sensitivity studies suggested glucosamine-induced changes in apoB-100 conformation. Endoglyco...

Glucosamine is widely used to relieve symptoms from osteoarthritis. Its safety and effects on glucose metabolism are critically evaluated in this review. The LD50 of oral glucosamine in animals is approximately 8000 mg/kg with no adverse effects at 2700 mg/kg for 12 months. Because altered glucose metabolism can be associated with parenteral administration of large doses of glucosamine in anima...

Accelerated atherosclerosis is one of the major vascular complications of diabetes. Factors including hyperglycemia and hyperinsulinemia may contribute to accelerated vascular disease. Among the several mechanisms proposed to explain the link between hyperglycemia and vascular dysfunction is the hexosamine pathway, where glucose is converted to glucosamine. Although some animal experiments sugg...
