Affymetrix Human Gene 1.0 ST Array (hugene10st)
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.

Description
Gata5 is a zinc finger transcription factor that is expressed in embryonic pulmonary mesenchyme and becomes upregulated in the lungs, gut, and bladder during postnatal development. We used microarray to comapre gene expression profiles of mouse lung between Gata5 knockout and wild type mice. We hope to identify the differentially expressed genes that affected by Gata5 gene deletion and their functional clusters or pathways.

Description
We constructed a polycistronic lentiviral vector to overexpress 3 germ cell specific genes (Stella, Oct4 and Nanos2) in mouse embryonic fibroblast (MEFs) and evaluated the transcriptome portrait in partially reprogrammed cells.We sequenced RNA samples from bulk cell population of two biological duplicates of MEF-GFP (control) and MEF-SON (overexpressed) 21 days post infection. Differential expression analysis of 50 M pair-end read per samples showed overexpression of neurogenesis, blood vessel and proliferation related genes and downregulation of chondroitin sulphate metabolic process, nitric oxide production and innate immune response genes. Overall design: Examination of whole transcriptome following concurrent overexpression of Stella, Oct4 and Nanos2 in MEFs.

Description
Invasive lobular carcinoma (ILC) is a histological subtype of breast cancer that is frequently associated with favorable outcomes, as ~90% of ILC express the estrogen receptor (ER). However, recent retrospective analyses suggest that ILC patients receiving adjuvant endocrine therapy may not benefit from improved outcomes versus other breast cancer patients. Based on these observations, we characterized ER function and endocrine response in ILC models. The ER-positive ILC cell lines MDA MB 134VI (MM134) and SUM44PE were used to examine the ER-regulated transcriptome in vitro via gene expression microarray analyses and ER ChIP-Seq. In parallel, estrogen response was assessed in vivo in the patient-derived ILC xenograft HCI-013. Response to endocrine therapy was also examined in ILC cell lines. We identified 915 genes that were uniquely E2-regulated in ILC cell lines versus other breast cancer cell lines, and a subset of these genes were also regulated in vivo in HCI-013. We observed that MM134 were de novo tamoxifen resistant, and were induced to grow by 4-hydroxytamoxifen, as well as other anti-estrogens, as partial agonists. Growth was accompanied by agonist activity of tamoxifen on ER-mediated gene expression. Though tamoxifen induced cell growth, MM134 cells required FGFR1 signaling to maintain viability and were sensitive to combined endocrine therapy and FGFR1 inhibition. Our observation that ER drives a unique program of gene expression in ILC cells correlates with the ability of tamoxifen to induce growth in these cells. Targeting growth factors using FGFR1 inhibitors may block survival pathways required by ILC and reverse tamoxifen resistance.

Description
Purpose: Transcriptome analysis of ESR1 mutant cells was performed via sequencing total RNA in T47D and MCF7 cell lines containing Y537S and D538G mutations. Overall design: Methods: Individual ESR1 WT and mutant T47D and MCF7 clones were hormone deprived in CSS for three days, pooled, and plated in quadruplicates in 6-well plates. The cells were treated with veh or 1nM E2 for 24 hrs, RNA was isolated and subjected to sequencing. Differential expression analysis was performed by DEseq2 and R was used to conduct statistical analysis tests

A data set of normal epithelium, serous ovarian surface epithelial-stromal tumors (benign and type II malignancies), stroma distal to tumor, and stroma adjacent to tumor (50 samples total). Additional cel files are included which represent replicate sampling from patients, and cel files that failed quality control but may be bioinformatically interesting. Additional replicate or failed cel files were not included in the final analysis (and so these samples were not included in the matrix).
Publication Title
