Comparative transcriptome analysis between immortalized ovarian surface epithelial (iOSE) and immortalized fallopian tube secretory epithelial (iFTE) cells

Project description:The transcriptomes of three immortalized ovarian surface epithelial cell lines (iOSE, PMID: 17266044) and primary OSE cells (Innoprot, Derio, Spain) and four immortalized fallopian tube secretory epithelial (iFTE) cell lines (PMID: 21502498, 22936217) were compared. RNA-sequencing was done from rRNA depleted total RNA (Ribo-Zero rRNA Removal Kit) to approx. 20 million 50 bp paired end reads per sample. A discriminative gene expression signature comprised of 211 genes was developed and used to classify isolated and EpCAM enriched primary ovarian cancer cells (PMID: 25991672). Impact of this signature on overall survival was assessed from several publicly available ovarian cancer gene expression data sets. Background: High grade serous ovarian cancer (HGSOC) is characterized by extensive local, i.e. peritoneal, tumor spread, manifested in two different clinical presentations, miliary (many millet sized peritoneal implants) and non-miliary (few large exophytically growing peritoneal nodes), and an overall unfavorable outcome. HGSOC is thought to arise from fallopian tube secretory epithelial cells, via so called serous tubal intraepithelial carcinomas (STICs) but an ovarian origin was never ruled out for at least some cases. Comparative transcriptome analyses of isolated tumor cells from fresh HGSOC tissues and (immortalized) ovarian surface epithelial and fallopian tube secretory epithelial cell lines revealed a close relation between putative origin and tumor spread characteristic, i.e. miliary from tubes and non-miliary from ovaries.

Global Proteomic Profiling in Chronic Iron-Exposed Fallopian Tube Secretory Epithelial Cells

Project description:We previously published (Oncogenesis, Rockfield et al., 2019) that chronic iron exposure (with ferric ammonium citrate, FAC) in immortalized fallopian tube secretory epithelial cells resulted in increased growth and migratory propensity. Our focused analyses identified a subset of oncogenic markers, including EVI1 (amplified at 3q26.2 in high grade serous epithelial ovarian tumors), that were altered following long term iron treatment. Herein, we have extended these studies to global proteomics analyses via a mass spectrometry (MS)-based approach.

Gene expression profiles of 2D- and 3D-cultured fallopian tube secretory epithelial cells

Project description:Background. Fallopian tube secretory epithelial cells (FTSECs) have been implicated as a cell-of-origin for high-grade serous epithelial ovarian cancer. However, there are relatively few in vitro models of this tissue type available for use in studies of FTSEC biology and malignant transformation. In vitro three-dimensional (3D) cell culture models aim to recreate the architecture and geometry of tissues in vivo and restore the complex network of cell-cell/cell-matrix interactions that occur throughout the surface of the cell membrane. Results. We have established and characterized 3D spheroid culture models of primary FTSECs. FTSEC spheroids contain central cores of hyaline matrix surrounded by mono- or multi-layer epithelial sheets. We found that 3D culturing alters the molecular characteristics of FTSECs compared to 2D cultures of the same cells. Gene expression profiling identified more than a thousand differentially expressed genes between 3D and 2D cultures of the same FTSEC lines. Pathways significantly under-represented in 3D FTSEC cultures were associated with cell cycle progression and DNA replication. This was also reflected in the reduced proliferative indices observed in 3D spheroids stained for the proliferation marker MIB1. Comparisons with gene expression profiles of fresh fallopian tube tissues revealed that 2D FTSEC cultures clustered with follicular phase tubal epithelium, whereas 3D FTSEC cultures clustered with luteal phase samples. Conclusions. This 3D model of fallopian tube secretory epithelial cells will advance our ability to study the underlying biology and etiology of fallopian tube tissues and the pathogenesis of high-grade serous epithelial ovarian cancer. 3 primary FTSEC lines were plated in 2D, or in 3D on polyHEMA coated plates

Early response of human ovarian and fallopian tube surface epithelial cells to norepinephrine

Project description:The purpose of this study is to understand the effects of adrenergic signaling on the transcriptome of cell line models postulated to be the cells of origin of epithelial ovarian cancers using RNA-Seq. Here we explored the effects of the stress-related hormone, norepinephrine, on normal human ovarian and fallopian tube surface epithelial cellss. We investigated the early transcriptional response to norepinephrine in normal immortalized ovarian surface epithelial cells and fallopian tube secretory cells. RNA-Seq data of treated and untreated cells were analyzed to identify genes with differential expression.

Transformation of the Fallopian Tube Secretory Epithelium Leads to High-grade Serous Ovarian Cancer in BRCA/P53/PTEN Models

Project description:Our study presents the first genetic models of de novo high-grade serous carcinomas (HGSC) that originate in fallopian tube secretory epithelial cells and recapitulate the key genetic alterations and precursor lesions characteristic of human invasive ovarian cancer. Genomic copy number analysis, using array CGH, was performed on murine tumors in order to compare the overlap of copy number alterations between HGSC models and TCGA data. Array CGH was performed on genomic DNA isolated from murine HGSC tumors. Genomic DNA from three normal mouse fallopian tubes was pooled and used as the reference.

Gene signatures of normal hTERT immortalized ovarian epithelium and fallopian tube epithelium (paired cultures from 2 donor patients)

Project description:Most epithelial ovarian cancers are thought to arise from different cells in the ovarian or fallopian tube epithelium. We hypothesized that these distinct cells-of-origin may play a role in determining ovarian tumor phenotype and also could inform the molecular classification of ovarian cancer. To test this hypothesis, we developed new methods to isolate and culture paired normal human ovarian (OV) and fallopian tube (FT) epithelial cells from multiple donors without cancer and identified a cell-of-origin gene expression signature that distinguished these cell types within the same patient. Application of the OV versus FT cell-of-origin gene signature to gene expression profiles of primary ovarian cancers permitted identification of distinct OV and FT-like subgroups among these cancers. Importantly, the normal FT-like tumor classification correlated with a significantly worse disease-free survival. This work describes a new experimental method for culture of normal human OV and FT epithelial cells from the same patient. These findings provide new evidence that cell-of-origin is an important source of ovarian tumor heterogeneity and the associated differences in tumor phenotype. We analyzed 12 samples from two donor patients and established cultures of both ovarian epithelium and fallopian tube epithelium (hTERT immortalized), each with 3 replicates (different culture passages).

Effect of norepinephrine and/or propranolol on fallopian tube epithelial cells in ultra-low attachment conditions

Project description:To investigate the role of norepinephrine on 3D spheroid formation and survival in early high-grade serous ovarian cancer, we cultured immortalized human fallopian tube epithelial cell lines in ultra-low attachment conditions in the presence or absence of norepinephrine and/or propranolol over 2 different timepoints.
