Project description:This trancriptome analysis reports genes that are differentially expressed in wildtype (WT) lens epithelial cells (LEC) between 6 hours and zero hours after injury.
Project description:This study investigates the response of human lens epithelial cells to mechanical injury. Human geriatric lenses obtained from cadaver eyes from donated to an eye bank for research were subject to in-vitro capsulotomy mimicking the injury sustained during cataract surgery. The anterior capsule was dissected using a curvilinear capsulorhexis technique, and central lens epithelial cells attached to the patch of anterior capsule (Rhexis) were immediately stabilized in RNAlater. The fiber cells were then removed, and the cortical fibers were immediately stabilized in RNA later. The remaining equatorial lens epithelial cells attached to the capsular bag from one eye were stabilized in RNA later immediately while the equatorial lens epithelial cells from the other eye were cultured for 24 hours then stabilized in RNAlater.
Project description:The purpose of this study was to investigate/characterize age- and sex-dependent changes in transcriptomic profile in a mouse model of cataract surgery that mimics human cataract surgery. This surgery involves the removal of lens fiber cells (LFC) leaving behind the lens capsule and associated lens epithelial cells (LEC). The lens capsule and associated remnant LECs were harvested either following cataract surgery (0 hour) or 24 hours later. Fiber cells were collected at the time of surgery, equivalent to 0 hour, and analyzed separately from epithelial cells. For samples from LEC, each biological replicate is a pool of 5 lens capsules from 5 independent mice. For samples from LFC, each biological replicate is a pool of 2 fiber cell masses from two independent mice. Mice were either 24 months old (Aged), or 3 months old (Young).
Project description:Total RNA was isolated from three separate populations of human lens epithelial cells and three matching populations of lens cortical fiber cells. All samples were analyzed on separate microarrays. Keywords: repeat sample
Project description:This trancriptome analysis reports genes that are differentially expressed in wildtype (WT) lens epithelial cells (LEC) between 6 hours and zero hours after injury, and between Egr1 (E1) or FosB (FB) null LEC and wildtype LEC at zero hours (0H) and at 6 hours (6H) after injury.
