Abstract
This work is the first comprehensive report on the quantitative metabolomic composition of the rat lens. Quantitative metabolomic profiles of lenses were acquired with the combined use of high-frequency nuclear magnetic resonance (NMR) and high-performance liquid chromatography with high-resolution mass-spectrometric detection (LC-MS) methods. More than forty low molecular weight compounds found in the lens have been reliably identified and quantified. The most abundant metabolites in the 3-month-old Wistar rat lens are taurine, hypotaurine , lactate, phosphocholine and reduced glutathione . The analysis of age-related changes in the lens metabolomic composition shows a gradual decrease of the content of most metabolites. This decrease is the most pronounced between 1 and 3 months, which probably corresponds to the completion of the lens maturation in one-month-old rats and to the high rate of the young lens growth. The enhanced levels of tryptophan , tyrosine , carnitine , glycerophosphate , GSH and GSSG were found in lenses of senescence-accelerated OXYS rats ; for some metabolites, this effect may probably be attributed to the compensatory response to oxidative stress . • Lens metabolomic profiling is performed by combination of NMR and LC-MS methods. • 42 metabolites found in the rat lens are identified and quantified. • The content of most metabolites decreases with age. • The level of some metabolites is elevated in lenses of senescence-accelerated rats.
