keratoconus/phosphatase

The purpose of the study was to identify genes that are differentially expressed in normal versus keratoconus corneas. Total RNA isolated from corneal stromal cell cultures was reverse-transcribed and then amplified by the polymerase chain reaction (PCR) using defined, arbitrary primers. The

OBJECTIVE To study the enhanced expression of leukocyte antigen-related tyrosine phosphatase (LAR) in human keratoconus cornea. METHODS Corneal buttons of patients received keratoplasty in Eye Center of Beijing Tongren from December 2001 to March 2002 were collected. Total RNA was isolated from the

OBJECTIVE Keratoconus is characterized by thinning and scarring of the central region of the cornea. The authors have shown, in corneas obtained from patients with keratoconus, that lysosomal enzyme activities are elevated, whereas levels of protease inhibitors such as alpha 1-proteinase inhibitor

OBJECTIVE To examine the lysosomal enzyme activities in the conjunctival tissues of patients with keratoconus. METHODS Tissues collected from 11 patients with keratoconus, eight patients with senile cataract, three patients with Fuchs' corneal dystrophy, and 11 normal control subjects were processed

OBJECTIVE Keratoconus is a progressive disease that thins and scars the corneal stroma. In keratoconus corneas, levels of degradative enzymes, including lysosomal acid phosphatase (LAP) and cathepsin B, are elevated, and those of the inhibitors alpha1-proteinase inhibitor (alpha 1-PI) and alpha

Keratoconus is a disease characterized by thinning and scarring of the central portion of the cornea. We have shown, in corneas and conjunctival tissues obtained from patients with keratoconus, that lysosomal enzyme staining is enhanced in the epithelial layer. In this study, we examined the

We studied the lysosomal enzyme activities in corneas obtained from 12 patients with keratoconus. Three acid hydrolases--acid phosphatase, acid esterase, and acid lipase--were demonstrated by histochemical staining methods in the epithelium, stroma, and endothelium of corneas with keratoconus and

Keratoconus is a potentially blinding disease that thins the central cornea. In afflicted corneas, the level of an inhibitor, alpha1-proteinase inhibitor (alpha1-PI), is found reduced. An increased expression of transcription factor Sp1 is also demonstrated. To examine the role of Sp1 in regulation

OBJECTIVE Activated myofibroblasts and macrophages are often found in corneal wound models. The current study was performed to determine whether human diseased corneas that had active tissue remodeling and enzyme activities also possessed myofibroblasts, macrophages, major histocompatibility complex

OBJECTIVE Keratoconus is a progressive disease that thins and scars the cornea. In keratoconus corneas, levels of degradative enzymes, including lysosomal acid phosphatase (LAP) and cathepsin B, are elevated, and those of inhibitors alpha1-proteinase inhibitor (alpha1-PI) and alpha2-macroglobulin
