Metabolomic studies on the biochemical profile of urine from rats with acute cysteamine supplementation

This study investigates the effect of acute cysteamine (CS) supplementation on rat metabolism. A metabolomic strategy using high-resolution 1H-NMR spectroscopy in conjunction with principal component analysis was applied to examine rat biological responses to CS administration. Half of female Sprague–Dawley rats (2 groups of 6 rats) were each given doses of 150 mg CS/kg body weight intraperitoneally. Urine samples were collected twice daily (0–8...
