PURPOSE To determine the expression patterns of the retinoblastoma protein and the E2F transcription factor families in limbal and corneal epithelia and in corneal keratocytes in situ during corneal development and differentiation. METHODS Retinoblastoma protein (pRb) and its family members p107 and p130; E2F-1, -2, and -4, members of the E2F family of transcription factors; and Ki67, a marke...
PURPOSE The cell cycle inhibitor p15(INK4b) has been localized in migrating corneal epithelial cells. In this study, TAT-fusion protein technology was used to transduce p15(INK4b) into human corneal epithelial cells to examine the effect on cell proliferation and migration. METHODS Human p15(INK4b), obtained by RT-PCR, was cloned into a TAT-HA vector, and the fusion protein was purified from ...
Purpose To screen for and characterize compounds that protect corneal endothelial cells against unfolded protein response (UPR) and oxidative stress. Methods Bovine corneal endothelial cells (BCECs) were treated for 48 hours with 640 compounds from a Food and Drug Administration (FDA)-approved drug library and then challenged with thapsigargin or H2O2 to induce UPR or oxidative stress, respec...
Statement of Purpose: Corneal blindness deprives 10 million people worldwide of their sight. Current treatments for corneal blindness mainly rely on implants that replace the injured tissue and have been clinically unsuccessful thus far. The goal of this project is to prevent corneal blindness by developing clinically-viable scaffolds that promote orderly corneal wound healing using biochemical...
OBJECTIVE To determine the effect of topical soluble tumor necrosis factor receptor type I (sTNFR-I) on survival of murine orthotopic corneal transplants and on ocular chemokine gene expression after corneal transplantation. METHODS BALB/c mice (N = 50) were used as recipients of multiple minor H-disparate corneal transplants from B10.D2 donors. After orthotopic corneal transplantation, mice ...
PURPOSE Urokinase-type plasminogen activator (u-PA) plays an important role in corneal wound healing, yet its role in corneal inflammation remains poorly understood. We investigated the role of u-PA in a murine model of lipopolysaccharide (LPS)-induced corneal inflammation. METHODS The corneal epithelium was scraped and LPS was applied to u-PA wild-type (u-PA(+/+)) and u-PA-deficient (u-PA(-/...
In the current study, we conducted a mutation screening of tumor-associated calcium signal transducer 2 (TACSTD2) gene in six consanguineous Iranian families with gelatinous drop-like corneal dystrophy (GDLD), in order to find the causative mutations. Detailed eye examination was performed by ophthalmologist to confirm GDLD in patients. To detect the possible mutations, direct Sanger sequencing...
Mitomycin C is an antimetabolite agent that blocks DNA and RNA replication and protein synthesis. It has been used in several ophthalmologic areas, and recently as a modulator of corneal wound healing in excimer laser surgeries. A single application of mitomycin C during surface corneal photoablative surgery seems a safe and efficient therapeutic option for eyes with corneal opacity and/or as p...
PURPOSE The purpose of this study was to examine expression of platelet-derived growth factor (PDGF) and PDGF receptors in the human cornea and to study the effects of the PDGF isotypes on proliferation and chemotaxis of human corneal fibroblasts. The effects of interleukin (IL)-1alpha, bone morphogenic protein (BMP)2, and BMP4 on chemotaxis of human corneal fibroblasts were also studied. MET...
