GlycA — a new biomarker of inflammation, cancer, cardiovascular disease and a predictor of death, regardless of its causes

Abstract

This review presents data on a recently discovered (2015) predictor for death regardless of its cause, a glycoprotein acetylation product, GlycA (biomarker of protein glycan N-acetyl groups). Subtle mechanisms of GlycA action in inflammation, cardiovascular diseases, cancer, and type 2 diabetes are discussed. A strong correlation of GlycA content with insulin resistance was found. The GlycA content increases with increasing age and body weight (BWI). High concentrations of GlycA are inversely proportional to global cognition, memory, and speed of information processing.
