Project description:Background: The study of human lacrimal gland biology and development is limited. Lacrimal gland tissue is damaged or poorly functional in a number of disease states including dry eye disease. Development of cell based therapies for lacrimal gland diseases requires a better understanding of the gene expression and signaling pathways in lacrimal gland. Differential gene expression analysis between lacrimal gland and other embryologically similar tissues may be helpful in furthering our understanding of lacrimal gland development. Methods: We performed global gene expression analysis of human lacrimal gland tissue using Affymetrix ® gene expression arrays. Primary data from our laboratory was compared with datasets available in the NLM GEO database for other surface ectodermal tissues including salivary gland, skin, conjunctiva and corneal epithelium. Results: The analysis revealed statistically significant difference in the gene expression of lacrimal gland tissue compared to other ectodermal tissues. The lacrimal gland specific, cell surface secretory protein encoding genes and critical signaling pathways which distinguish lacrimal gland from other ectodermal tissues are described. Conclusions: Differential gene expression in human lacrimal gland compared with other ectodermal tissue types revealed interesting patterns which may serve as the basis for future studies in directed differentiation among other areas.

Project description:Diagnosis of inflamed human lacrimal gland with standard clinical and histopathology evaluation data is imprecise. A large number of these patients are diagnosed with the catch-all classification of nonspecific orbital inflammation (NSOI). We utilized gene expression analysis of lacrimal gland biospy/surgical waste tissues to assist in the classification of sarcoidosis, granulomatosis with polyangiitis (GPA), thyroid eye disease (TED), and subdivisions of NSOI. As part of this process, we are investigating correlations between gene expression levels and disease characteristics.

Project description:The Effect of Aromatase Knockout on Gene Expression in the Mouse Lacrimal and Meibomoan Gland. Keywords: Aromatase Knockout vs Wild Type Control Lacrimal and meibomian glands were harvested from homozygous male and female aromatase knockout mice and age matched wild type controls. Tissues were pooled into 3 biological replicates and were hybridized to separate microarrays. Each cRNA prep was hybridized to a GE Healthcare/Amersham Biosciences CodeLink UniSet Mouse 20K I Bioarray and a Affymetrix GeneChip Mouse Expression Array 430A.

Project description:PURPOSE: The hypothesis tested in the study was that the effect of estrogen and progesterone on the lacrimal gland is mediated through specific receptors and that hormonal effects involve the regulation of gene expression and protein synthesis. METHODS: Lacrimal glands were collected from young adult, ovariectomized mice, that were treated with 17beta-estradiol, progesterone, 17beta-estradiol plus progesterone or vehicle for 2 weeks. Glands were pooled according to treatment, processed for the isolation of RNA, and evaluated for differentially expressed mRNAs by using gene microarrays. Bioarray data were analyzed with sophisticated bioinformatics and statistical programs. The expression of selected genes was verified by using gene chips and quantitative real-time PCR methods. RESULTS: The results demonstrate that 17beta-estradiol, progesterone, or both hormones together significantly influences the expression of hundreds of genes in the mouse lacrimal gland. Sex steroid treatment led to numerous alterations in gene activities related to transcriptional control, cell growth and/or maintenance, cell communication, signal transduction, enzyme catalysis, immune expression, and the binding and metabolism of nucleic acids and proteins. A number of the 17beta-estradiol, progesterone or 17beta-estradiol plus progesterone effects on gene expression were similar, but most were unique to each treatment. Of particular interest was the finding that these hormones seem to contribute little to the known sex-related differences in gene expression of the lacrimal gland. CONCLUSIONS: These results support the hypothesis that estrogen's and progesterone's action on the lacrimal gland involves the regulation of numerous genes. However, these hormone effects do not appear to represent a major factor underlying the sexual dimorphism of gene expression in lacrimal tissue. Keywords: Placeco vs Hormone Treatment
