Study TitleSphingolipid Analysis of Human Aqueous Humor in Glaucomatous and Control eyes (part I)
Study SummaryThis study examined the profiles of sphin¬golipids and ceramides present in the aqueous humor (AH) of human control and POAG donors. Furthermore, we quantitatively compared distinct differences between glaucomatous and age-matched control eyes, identifying potential molecules for further experimentation to determine their biological role in modulating cell behavior. Lipids were identified and ratiometrically quantified in a two-step process using precursor ion scan (PIS) or neutral loss scan (NLS) with appropriate class-specific lipid standards on a TSQ Quantum Access Max mass spectrometer following established procedures. We identified several species of sphingomyelin, sphingoid base, sphingoid base-1-phosphate, and ceramides that were common between control and glaucomatous AQH. Some unique lipid species in these classes were also identified in controls but not in glaucoma and vice versa.
