Project description:The data in this submission relate to whole exome sequencing from murine ovarian cancer cell line ID8. All sequencing was performed by Beckman Coulter Genomics, Grenoble, France in February 2013.
Project description:Ovarian cancer is the leading cause of gynecological cancer related death. The overall 5 year survival rate is only 29%. Over 85% of ovarian cancer patients present with advanced stage III or IV disease characterized by intraperitoneal metastasis when diagnosed. However, the process and mechanism of ovarian tumor metastasis remain poorly understood partially because of the lack of a mouse model which could recapitulate the development of metastatic lesion in an appropriate timeframe. In order to generate a convenient ovarian cancer model with accelerated peritoneal metastasis, we performed an in vivo selection study using ID8 ovarian cancer cells to establish a rapid metastasizing mouse ovarian cancer cell line, designated ID8-M. Syngeneic mice with intraperitoneal inoculation of ID8-M cells showed measurable ascites average 35 days after the inoculation and survived only an average of 52 days, while those inoculated with parental ID8 cells showed measurable ascites after 67 days and survived over 81 days. Further analysis showed that, compared with ID8 tumors, ID8-M tumors resulted in more macrophages in the ascites; and compared to ID8 cells, ID8-M cells were more potent to promote macrophages to acquire a M2 phenotype. A microarray analysis provided information to explain the accelerated metastatic phenotype of ID8-M cells.
Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The objective of this experiment was to examine the direct activity of interferon epsilon on the mouse ovarian cancer cell line, ID8, and compare it to equivalent unit concentrations of interferon beta. The goal was to determine whether interferon epsilon and interferon beta induce different patterns of gene expression in ID8 cells.
Project description:Genetically modified ovarian cancer cells were used to study the role of GBP1. Proteomics-based thermal stability assay (CETSA) was performed on GBP1 knockdown and overexpressing ID8 ovarian cancer cells. Shotgun proteomics was also performed on these cells.
Project description:Sequencing of mRNA from ID8 tumor cells and ID8 tumor cells harvested from ascites of mice 11 weeks after intra peritoneal inoculation show acquisition of cancer stem cell-like features in ascitic tumor cells.
Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The goal of this experiment was to assess whether interferon signalling had been ablated in Ifnar1 CRISPR knockout (KO) ID8 cell lines, so that they could be used for in vivo models of ovarian cancer.
Project description:ID8 mouse ovarian surface epithelial cells with or without K454R mutant and knockout of FAK were cultured as spheroid cultures. The cells were hypotonically lysed and washed out, and the insoluble material was analyzed by LC-MS/MS.
Project description:ARID1A, which encodes a component of the SWI/SNF chromatin-remodeling complex, is commonly mutated in ovarian clear cell carcinoma and many other cancer types. We used label-free LC-MS/MS to identify ARID1A-dependent proteome changes in ovarian clear cell carcinoma cell lines. In our first analysis, we compared ARID1A-wildtype ovarian clear cell carcinoma cell line OVCA429 with or without ARID1A CRISPR knockout. In a complementary analysis, we compared ARID1A-mutated ovarian clear cell carcinoma cell line OVISE with or without ARID1A overexpression using a tet-inducible promoter.
