ABSTRACTAlthough clinical trials with glucosamine in osteoarthritis have yielded mixed results, leading to doubts about its efficacy, the utility of glucosamine for preventing joint destruction and inflammation is well documented in rodent models of arthritis, including models of spontaneous osteoarthritis. The benefit of oral glucosamine in adjuvant arthritis is markedly dose dependent, likely reflecting a modulation of tissue levels of UDP-N-acetylglucosamine that in turn influences mucopolysaccharide synthesis and the extent of protein O-GlcNAcylation. Importantly, the minimal oral dose of glucosamine that exerts a detectible benefit in adjuvant arthritis achieves plasma glucosamine levels similar to those achieved when the standard clinical dose of glucosamine, 1.5 g daily, is administered as a bolus. The response of plasma glucosamine levels to an increase in glucosamine intake is nearly linear. Remarkably, every published clinical trial with glucosamine has employed the same 1.5 g dose that Rottapha...

Plasma levels of the inflammatory biomarker high-sensitivity C-reactive protein (hsCRP) predict vascular risk with an effect estimate as large as that of total or high-density lipoprotein cholesterol. Further, randomized trial data addressing hsCRP have been central to understanding the anti-inflammatory effects of statin therapy and have consistently demonstrated on-treatment hsCRP levels to be as powerful a predictor of residual cardiovascular risk as on-treatment levels of low-density lipopro...

Background context Glucosamine has gained widespread use among patients, despite inconclusive efficacy data. Inconsistency in the clinical literature may be related to lack of understanding of the effects of glucosamine on the intervertebral disc, and therefore, improper patient selection.

Background Glucosamine and chondroitin are popular non-vitamin dietary supplements used for osteoarthritis. Long-term use is associated with lower incidence of colorectal and lung cancers and with lower mortality; however, the mechanism underlying these observations is unknown. In vitro and animal studies show that glucosamine and chondroitin inhibit NF-kB, a central mediator of inflammation, but no definitive trials have been done in healthy humans.

Abstract Objectives: Glucosamine and chondroitin supplements have been shown to have anti-inflammatory properties in both in vitro studies and animal models; however, little is known about these relationships in humans. The VITamins and Lifestyle (VITAL) biomarker study evaluated the associations between use of these supplements and a panel of circulating inflammatory biomarkers. Design: Study participants included 217 men and women age 50–75 years living in the Seattle metropolitan area. Use of...

Background and Aim Epidemiological evidences suggested an inverse association between the use of glucosamine supplements and colorectal cancer (CRC) risk. In this study, the efficacy of glucosamine to attenuate dextran sodium sulfate (DSS)-induced colitis, a precancerous condition for CRC, was evaluated. Methods C57BL/6 mice were separated into three groups receiving glucosamine sulfate at concentrations of 0, 0.05, and 0.10% (w/w) of AIN-93G diet, respectively for 4 weeks. Colitis was induced b...

D-Glucosamine (GlcN) is a freely available and commonly used dietary supplement potentially promoting cartilage health in humans, which also acts as an inhibitor of glycolysis. Here we show that GlcN, independent of the hexosamine pathway, extends Caenorhabditis elegans life span by impairing glucose metabolism that activates AMP-activated protein kinase (AMPK/AAK-2) and increases mitochondrial biogenesis. Consistent with the concept of mitohormesis, GlcN promotes increased formation of mitochon...

Abstract Cigarette smoking causes persistent lung inflammation that is mainly regulated by redox-sensitive pathways. We have reported that cigarette smoke (CS) activates a NADPH oxidase-dependent reactive oxygen species (ROS)-sensitive AMP-activated protein kinase (AMPK) signaling pathway leading to induction of lung inflammation. Glucosamine, a dietary supplement used to treat osteoarthritis, has antioxidant and anti-inflammatory properties. However, whether glucosamine has similar beneficial e...

ABSTRACT There is a debate on the dose dependency, concentration-effect, hence, the beneficial effect of glucosamine (GlcN), a widely used anti-inflammatory natural product. We investigated dose/concentration-effect relationship and determined its minimum effective dose/concentration in rats with adjuvant arthritis (AA, Mycobacterium butyricum in squalene) both as preventive and ameliorating interventions. To control already emerged arthritis, rats received oral doses of placebo or 160 mg/

The post-translational modification of serine and threonine residues of proteins by O-linked β-N-acetylglucosamine (O-GlcNAc) is highly ubiquitous, dynamic and inducible. Protein O-GlcNAcylation serves as a key regulator of critical biological processes including transcription, translation, proteasomal degradation, signal transduction and apoptosis. Increased O-GlcNAcylation is directly linked to insulin resistance and to hyperglycemia-induced glucose toxicity, two hallmarks of diabetes and diab...
