Collection:

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.
Sample Type:Eye tissue

Treatment:

Treatment ID:TR000661
Treatment Summary:No treament was performed on tissue.

Sample Preparation:

Sampleprep ID:SP000654
Sampleprep Summary:Isolated trabecular meshwork tissue was subjected to an alternating cycle of immersion in liquid nitrogen and 37˚C, followed by extraction of lipids using a modified Bligh and Dryer method.13 The organic phase with extracted lipids was dried in a Speed-Vac (Model 7810014; Labconco, Kansas City, MO). Samples were flushed with argon gas to prevent oxidation. Corresponding aqueous phase extracted proteins were subjected to determination of concentration using Bradford’s method. A subset of protein samples also were subjected to densitometric quantification using bovine serum albumin as a standard (amino acid quantified) after electrophoretic separation on a PHAST (GE Healthcare Bio-Sciences AB, Uppsala, Sweden) gel system. All extractions and subsequent handling were made using glass vials, and polyvinyl plastic was avoided completely. We also added a PC control standard during tissue homogenization, determined its recovery in an aliquot, and used for the calculation of total recovery of this standard for each extraction to ensure >99% recovery of added standard during extraction.
