Project description:Pnn depletion in developing mouse corneal epithelium led to disrupted alternative splicing of multiple ESRP-regulated epithelial-type exons. In human corneal epithelial cells (HCET), ESRP1 and PNN displayed close localization in and around nuclear speckles and their physical association in protein complexes was identified. In this study, gene expression profiling was performed to identify PNN- and ESRP1-regulated alternative pre-mRNA splicing in human corneal epithelial cells. Immortalized human corneal epithelial cells harboring doxycycline-inducible shRNA against PNN or ESRP1 were created. Whole transcriptome array analysis on ESRP1 or PNN knockdown HCET cells revealed clear alterations in transcript level and splicing pattern of specific subsets of genes with significant overlaps in their candidate targets. Our data suggest that ESRP1 and PNN modulate alternative splicing of a specific subset of exons, but not general splicing events. ESRP1 and PNN may together participate in the regulation of epithelial-specific splicing program in a genome-wide fashion. Parental HCET, shRNA-PNN HCET, and shRNA-ESRP1 HCET cells were cultured for 3 days with/without doxycycline. Total RNA was isolated from four biological replicates of each sample group and then subjected to hGlue3_0 transcriptome array analysis.

Project description:Genome-wide analysis of dihydrotestosterone (DHT) induced changes in gene expression in primary and immortalized human corneal epithelial cells. Analysis of regulation of primary and immortalized human corneal 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 corneal cells is influenced by androgens through regulation of the expression of multiple genes. Results provide important information of the differential regulation and comparitive analysis of numerous genes in response to dihydrotestosterone incubation in primary and immortalized human corneal epithelial cells. Total RNA was obtained from primary and immortalized human corneal epithelial cells treated for 5 days 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 the primary human corneal cells grown in our laboratory and the immortalized human corneal 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)].

Project description:To elucidate the epithelial cell diversity within the nasal inferior turbinates, a comprehensive investigation was conducted comparing control subjects to individuals with house dust mite-induced allergic rhinitis. This study aimed to delineate the differential expression profiles and phenotypic variations of epithelial cells in response to allergic rhinitis. This research elucidated distinct subpopulations and rare cell types of epithelial cells within the nasal turbinates, discerning alterations induced by allergic rhinitis. Furthermore, by interrogating transcriptomic signatures, the investigation provided novel insights into the cellular dynamics and immune responses underlying allergic rhinitis pathogenesis
