Plasma levels of pentosidine in diabetic patients: an advanced glycation end product.

Nonenzymatic reactions between glucose and proteins yield advanced glycation end products (AGE) such as pentosidine. AGE accumulate in diabetic patients, alter the structure and function of tissue proteins, stimulate cellular response, and have thus been implicated in diabetic tissue damage. The present study was undertaken to assess the factors determining plasma total pentosidine level in dia...

Pentosidine, an Advanced Glycation End-Product, May Reflect Clinical and Morphological Features of Hand Osteoarthritis

The study investigates pentosidine levels, an advanced glycation end-product, in patients with erosive and non-erosive hand osteoarthritis (HOA) and determine its potential association with clinical findings and imaging-defined joint damage.Pentosidine was measured by HPLC in serum and urine of 53 females with HOA (31 erosive and 22 non-erosive HOA) and normalised to the total serum protein or ...

Advanced glycation end-product pentosidine accumulates in various tissues of rats with high fructose intake.

The slowly metabolized proteins of the extracellular matrix, typically collagen and elastin, accumulate reactive metabolites through uncontrolled non-enzymatic reactions such as glycation or the products arising from the reaction of unsaturated long chain fatty acid metabolites (possessing aldehydic groups). A typical example of these non-enzymatic changes is the formation of advanced glycation...

High serum level of pentosidine, an advanced glycation end product (AGE), is a risk factor of patients with heart failure.

BACKGROUND Pentosidine, one of the advanced glycation end products (AGE), is generated by nonenzymatic glycation and oxidation of proteins. The receptor of AGE (RAGE) is expressed in a variety of tissue, and interaction of AGE with RAGE induces oxidative stress and activation of intracellular signaling, causing production of cytokines and mediators of inflammation. We investigated whether serum...

Increase in the advanced glycation end product pentosidine in Bruch's membrane with age.

PURPOSE To determine whether there is an age-related increase of pentosidine in human Bruch's membranes and to localize pentosidine and carboxymethyllysine (CML), two well-characterized, advanced glycation end products (AGEs) in aged human Bruch's membranes and choroid in vivo. METHODS Human Bruch's membrane samples were isolated from the retinal pigment epithelium (RPE) and choroid and subje...
