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.

Ascites extracellular vesicle microRNA profiles of platinum-resistant high-grade serous ovarian carcinoma

Project description:Ovarian cancer is one of the leading causes of death in females in the world. High-grade serous ovarian carcinoma (HGSOC) is the most common histological subtype, and the platinum-resistance is a clinical challenge. HGSOC frequently spreads to the peritoneal cavity and causes carcinomatous peritonitis. Extracellular vesicles (EVs) are lipid-bilayer nanoparticles containing various bioactive molecules. Thus, EVs mediate cell-to-cell communication and contribute to cancer progression. Moreover, EVs stably exist in the body fluid, including serum and ascites. This study investigated the ascites EV miRNA profiles of platinum-resistant and platinum-sensitive HGSOC.

Gene expression profile of tumor cells from primary tumors, ascites and metastases of high grade serous ovarian cancer patients

Project description:HGSOC, the most aggressive form of OC, is characterized by insidious onset, rapid intraperitoneal spread and development of massive ascites. Peritoneal adhesion was considered as the first step of abdominal metastasis, underscoring that only tumor cells gain access to peritoneal adherence contribute to metastasis. Studies on ovarian cancer progression were mainly focused on the primary and metastatic tumor cells, while understanding of the ascitic tumor cells is limited. We hypothesized that uncovering the gene expression profiles of ascitic tumor cells from high grade serous ovarian cancer patients will allow us to understand more specifically their unique phenotype which mediates the peritoneal adhesion. In this study, gene expression profiling was completed for 15 magnetic sorted tumor cells samples from matched primary tumors, ascites and metastases of 5 high grade serous ovarian cancer patients. By comparing the expression data from ascitic tumor cells with primary and metastasis tumor cells, we identified a set of differential expressed genes in ovarian ascitic tumor cells advantageous for peritoneal adhesion and metastasis. Further study revealed that ascites microenvironment modulated the ascitic tumor cells phenotype and contributed to ovarian cancer dissemination through facilitating CAFs in formation of compact spheroids with ascitic tumor cells. We used microarrays to profile the expression of 15 matched tumor cells samples in order to identify molecular alteration between primary tumor cells, ascitic tumor cells and metastatic tumor cells in high grade serous ovarian cancer.

Gene expression profile of tumor cells from primary tumors, ascites and metastases of low grade serous ovarian cancer patients

Project description:Differ from the aggressive nature of HGSOC (high grade serous ovarian cancer), LGSOC (low grade serous ovarian cancer) is characterized by an early age of disease onset, slow growth pattern, and poor response to chemotherapy. To understand more specifically the underlying gene profiling discrepancy that contributes to their behavior distinction, we performed parallel gene expression profiling in 9 magnetic sorted tumor cells samples from matched primary tumors, ascites and metastases of 3 LGSOC patients as in HGSOC. By comparing the expression data among primary tumor cells, ascitic tumor cells and metastasis tumor cells, we identified a set of differential expressed genes along LGSOC progression. Further study revealed that the gene phenotype perturbance along LGSOC progression was quite different from that of HGSOC patients. We used microarrays to profile the expression of 9 matched tumor cells samples in order to identify molecular alteration between primary tumor cells, ascitic tumor cells and metastatic tumor cells in low grade serous ovarian cancer.
