Identification of a Potential Ovarian Cancer Stem Cell Gene Expression Profile from Advanced Stage Papillary Serous Ovarian Cancer

ABSTRACT: To identify the potential ovarian cancer stem cell gene expression profile from isolated side population of fresh ascites obtained from women with high-grade advanced stage papillary serous ovarian adenocarcinoma Microarrays were used to interrogate the differentially expressed genes between side population (SP) and main population (MP) isolated from fresh ascites obtained from women with high-grade advanced stage papillary serous ovarian adenocarcinoma, and the results were analyzed by paired T-test using BRB-ArrayTools

MiRNA profiles of high grade serous papillary ovarian cancer tumors and normal fallopian tube epithelium

Project description:Fallopian tube epithelium is the tissue-of-origin of most high grade serous papillary ovarian carcinoma. This tumor has been exensively investigated and sequenced but expression profiling data of normal fallopian tube epithelial cells is still rare. This project compares the miRNA profiles of high grade serous papillary ovarian tumors (FFPE and fresh frozen) to that of normal unmatched epithelial cells from resected fallopian tubes.

Genome-wide analysis of mRNA expression alterations in Stage III-IV high-grade serous ovarian cancer patients exhibiting clinically defined differences in ascites volume (high volume ascites versus low volume ascites)

Project description:Microarrays were used to examine gene expression changes in the surgical resections of high-grade serous ovarian cancer patients exhibiting clinically distinct levels of ascites volume. The present studies primary aim was to determine if there is a molecular gene expression difference between the patients presenting at time of surgery when high volumes ascites cases were compared to those with low volume ascites. The secondary aim was to determine what relevance this difference, if found, has to previously discovered molecular sub-types of high grade serous ovarian cancer. Total RNA obtained from snap-frozen stage III-IV high-grade serous ovarian cancer patients presenting with low volume (<=200 cc) or high volume (>=1000 cc) ascites volume.

Transcription profiling of human late-stage, high-grade papillary serous ovarian adenocarcinomas

Project description:To demonstrate the use of a whole-genome oligonucleotide array to perform expression profiling on a series of microdissected late-stage, high-grade papillary serous ovarian adenocarcinomas to establish a prognostic gene signature correlating with survival and to identify novel survival factors in ovarian cancer. Advanced stage papillary serous tumors of the ovary are responsible for the majority of ovarian cancer deaths, yet the molecular determinants modulating patient survival are poorly characterized. We identify and validate a prognostic gene expression signature correlating with survival in a series of microdissected serous ovarian tumors. Experiment Overall Design: We identified 53 advanced stage, high-grade primary tumor specimens and 10 normal ovarian surface epithelium (OSE) brushings.

Gene Expression Profiling of Human High-Grade Serous Ovarian Tumor Samples

Project description:The goal of the study was to further delineate the molecular signatures associated with high-grade serous ovarian cancer in order to develop validated clinically useful prognostic signatures with the potential to guide therapy decisions. Fresh frozen samples were prospectively collected from a series of 174 consecutive women with high-grade serous ovarian, primary peritonial, or fallopian tube cancer who underwent surgery by a gynecologic oncologist at Mayo Clinic betweern 1994 and 2005. All patients received postoperative chemotherapy with a platinum agent, and 75% received a taxane. All patients signed an Institutional Review Board approved consent for bio-banking, clinical data extraction and molecular analysis. Median follow-up time was 35 months (range, 1-202 months). Fourteen patients (8%) were included in the TCGA study.
