Project description:Human conjunctival cell lines are useful tools for modeling ocular surface disease and evaluation of ocular drugs. Here we demonstrate that the IOBA-NHC and the ChWK conjunctival epithelial cell lines show, using an unbiased gene microarray approach, unique gene expression signatures that differ from primary conjunctival epithelial cells (PCEC) and conjunctival tissue. Globally, the expression profile obtained with the Affymetrix U133A chip (>22000 genes) from PCEC was clustered more closely to conjunctival tissue than either of the 2 cell lines. However, when restricted to Gene Ontology sub-categories: cellular defense, viral replication/cycling, antigen presentation, anti-oxidant pathways and ubiquitin ligase complex, the cell lines correlated reasonably well to PCEC (r > 0.70). In the category response to inflammation, correlation of cell lines to PCEC was poor (r = -0.012 and –0.041 for IOBA-NHC and ChWK respectively). In general, the expression profile in IOBA-NHC cells was better correlated to PCEC than the ChWK cells. This was statistically significant (p<0.05) when one considers all the genes on the chip, or for proteins in the extracellular region, response to wounding, stress, lipid, protein and organic acid metabolism, development and differentiation. Our results are useful for the choice of conjunctival cell lines, if necessary, in future experiments, to increase validity of extrapolation to clinical scenarios. Keywords: Cell type comparison

Project description:Genome-wide analysis of dihydrotestosterone (DHT) induced changes in gene expression in immortalized human conjunctival epithelial cells. Analysis of regulation of immortalized human conjunctival epithelial cells by dihydrotestosterone at gene expression level. The hypothesis tested in the present study was that the androgen-eye interaction in ocular surface epithelial cells like conjunctival cells is influenced by androgens through regulation of the expression of multiple genes. Results provide important information of the differential regulation of numerous genes in response to dihydrotestosterone incubation of immortalized human conjunctival epithelial cells.

Project description:This study characterizes the transcriptional profile and the cellular tumor microenvironment of conjunctival lymphoma and identifies prognostically relevant biomarkers. 10 formalin-fixed and paraffin-embedded conjunctival lymphoma and 8 healthy conjunctival specimens were analyzed by MACE RNA sequencing. The 3,417 upregulated genes in conjunctival lymphoma were involved in processes such as B cell proliferation and Rac protein signaling, whereas the 1,188 downregulated genes contributed most significantly to oxidative phosphorylation and UV protection. The tumor microenvironment, as determined by deconvolution analysis, was mainly composed of multiple B cell subtypes which reflects the tumor’s B cell lineage. However, several T cell types, including T helper 2 cells and regulatory T cells, as well as innate immune cell types, such as anti-inflammatory macrophages and plasmacytoid dendrit-ic cells, were also strongly enriched in conjunctival lymphoma. A 13-biomarker prognostic panel, including S100A8 and S100A9, classified ocular and extraocular tumor recurrence, exceeded prognostic accuracy of Ann Arbor and AJCC staging, and demonstrated prognos-tic value for patient survival in 21 different cancer types in a database of 12,332 tumor pa-tients. These findings may lead to new options of targeted therapy and may improve prog-nostic prediction for conjunctival lymphoma.

Results provide important information of the differential regulation of numerous genes in response to dihydrotestosterone incubation of immortalized human conjunctival epithelial cells. Total RNA was obtained from immortalized human conjunctival epithelial cells treated for 96 hours with 10 nM dihydrotestosterone (n=3) or vehicle (n=3). The RNA was then used with Illumina HumanHT-12 v3 Expression BeadChips to determine the effect of DHT on gene expression in an immortalized human conjunctival epithelial cell line developed in Dr. Rheinwald's laboratory [Rheinwald et al. MCB, 22 (14): 5157. (2002)] and charecterized in Dr. Ilene Gibson's laboratory [Gipson et al. IOVS, 44 (6): 2496. (2003)].
