ABSTRACT: The whole transcriptome expression profiling comparison between the Pin1 knockIn in Hose cells and Pin1 knockdown in ovarian cancer MCAS and SK-OV-3 cells
Project description:To discover the abnormal regulatory role of Pin1 in the ovarian cancer, The Pin1 full cDNA was knockIn (KI) the normal ovarian epithelium (Hose), and parallelly Pin1 was knockdown in the Ovarian cancer cells MCAS and sk-ov-3, and then compared the expression profiles of them to discovery the key features regulated by Pin1.
Project description:Functional changes were investigated in vitro and in vivo following spontaneous fusion and hybrid cell formation in co-cultures of primary human mesenchymal stroma/stem-like cells (MSC) with human SK-OV-3 ovarian cancer cells. Lentiviral fluorescence-labeled MSC with eGFP and ovarian cancer cells labeled with mcherry resulted in dual-fluorescing hybrid cells. Double FACS sorting and single cell cloning revealed two different aneuploid hybrid populations (SK-hyb1 and SK-hyb2)
Project description:Bone morphogenetic proteins (BMPs) are extracellular signaling molecules that belong to the transforming growth factor beta (TGF-β) superfamily. By regulating target gene transcription, BMPs control various cellular processes, such as proliferation, differentiation, apoptosis and migration. In addition, rBMP2 was used to observe BMP signaling in treatment of ovarian cancer cell line SK-OV-3. We attempted to address the possible roles of BMP signaling by inhibiting a wide-range of downstream pathways using a small molecule inhibitor of type I BMPRs, dorsomorphin. The potential utility of this molecule as a molecular inhibitor of BMP signaling in treatment of ovarian cancer cell line SK-OV-3 was also evaluated. SK-OV-3 cells were incubated in 12 separate culture dishes, 3 dishes with PBS, 3 dishes with recombinant BMP2 (rBMP2) (100 ng/ml), 3 dishes with DM (5 μM) and 3 dishes with recombinant BMP2 (rBMP2) (100 ng/ml) plus DM (5 μM) in the culture medium for 24 hours prior to the analysis.
Project description:To investigate the role of PAI-1 (SERPIN E1) in ovarian cancer, we performed several in vitro assays using SK-OV-3 cells in which PAI-1 had been knocked down by siRNA, treated with platelets, or both. We then performed a comparative gene expression analysis using RNA-Seq data from untreated cells, PAI-1 siRNA knockdown or negative control, each with and without incubation with healthy donor platelets.
Project description:Knocking down of CSE1L made ovarian cancer cells, but not other cancer and normal cell lines, sensitized to cisplatin and triggered apoptosis. The nuclear localization in ovarian cancer cells suggested that CSE1L might primarily regulate transcription. . Using microarrays, we evaluated the expression profiles of CSE1L silenced SK-OV-3 and TOV-21G cells
Project description:Platinum-based compounds exert their anti-neoplastic effect through direct binding to DNA, which blocks fundamental cellular process ultimately resulting in apoptotic cell death. However, many ovarian cancers become refractory to treatment with platinum-based compounds. To improve the existing therapies for ovarian cancer, we sought to identify potent, nontoxic and specific drug candidates that have anti-neoplastic effects towards cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. Using a cell-based screening assay, we evaluated 56 compounds-derived from the Chinese medicinal plant, Phytolaccae, and one phytoaccagenin compound (Hu-17) was selected on the basis of its ability to dramatically decrease the viability of cisplatin-resistant SK-OV-3 cells.Using high-throughtput microarray system, we identified GO terms and pathway signatures enriched in Hu-17 and/or cisplatin treated SK-OV-3 cells.

Project description:SK-OV-3 cells under prolonged carboplatin exposition turn into giant cells. This dataset contains the transcriptome of cultured SK-OV-3 cells with and without carboplatin.
Project description:Ovarian cancer cells treated with CDDP showed up-regulation of IRF-1 and IRF-7. The expression of putative IRF-1 target genes was modulated. CDDP triggered nuclear translocation of IRF-1 and IRF-1 silencing re-orchestrated the expression profiles of CDDP treated cells. Using microarrays, we evaluated the expression profiles of IRF-1 silenced SK-OV-3.
