| Study Title | Human trabecular meshowrk phospholipid profiles of control and glaucomatous eyes |
| Study Summary | We compared phospholipid (phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, and phosphatidylinositol) profiles of control and glaucomatous trabecular meshwork (TM) derived from human donors.Lipid extraction was performed using a modification of the Bligh and Dyer method, protein concentrations were determined using the Bradford method, and for select samples confirmed with densitometry of PHAST gels. Lipids were identified and subjected to ratiometric quantification using a TSQ quantum Access Max triple quadrupole mass spectrometer with precursor ion scan (PIS) or neutral ion loss scan (NLS), using appropriate class specific lipid standards. |

| Collection ID: | CO000641 |
| Collection Summary: | Donor tissues were used following the institutional review board approved protocols and adhering to the tenets of the Declaration of Helsinki. Control TM and a subset of primary open-angle glaucoma (POAG) TM were collected from cadaver donors, a limited subset of POAG surgical specimen (acquired under institutional review board approved/exempted protocols) also were used for these studies. Cadaver donor tissues were sourced from Midwest Eye-Banks, Lions Eye Bank (Miami, FL), National Disease Research Interchange (NDRI; Philadelphia, PA), and Mundorf Eye Institute (Charlotte, NC). The postmortem time ranged from 3 to 16 hours. Control TM was stored briefly in Optisol at 48 and then used for lipid extraction. POAG TM tissues were stored at -80˚C until time of use. The mean age of control donors was 58.2 +/- 13.7 years and the mean age of glaucomatous TM donors 66 +/- 9.5 years. |
