Project description:CHSY1 has high expression in malignant tumor cells, such as colorectal cancer and ovarian cancer, and is associated with poor prognosis.The proliferation and invasion of ovarian cancer cells are weakened after knocking down CHSY1 with shRNA transfected We used microarrays to detail the global programme of gene expression underlying CHSY1 knockdown and identified distinct classes of up-regulated and down-regulated genes.
Project description:Ovarian clear cell carcinoma (OCCC) is a morphologically and biologically distinct subtype of ovarian carcinomas. We previously reported a gene expression profile characteristic of OCCC (OCCC signature), which contains hepatocyte nuclear facter-1b ( HNF-1b). To elucidate the biological role of HNF-1b in OCCC, we performed the suppression of the HNF-1b expression in human ovarian cancer cell line RMG2 using short hairpin RNA. We are now evaluating the functional effect using these cells. Affimetrix Human Genome U133A plus 2.0 chips was conducted for HNF1b knockdown and non-silencing cells (five replicates each for RMG2-HNF1b-sh1 and RMG2-HNF1b-sh2, ten replicates for the RMG2-control). All specimens were arrayed in parallel and used for RMA normalization.
Project description:To discover the core gene expression features of CtBP1, CtBP2 differently regulated in ovarian cancer SKOV3 cells. The compared the whole transcript expression profiling between CtBP1 knockdown, CtBP2 knockdown and scramble control in ovarian cancer skov3 cells.

Project description:RNA-sequencing was performed to gain insight into the mechanism responsible for the mesenchymal-to-epithelial transition (MET) induced by loss of long non-coding RNA (lncRNA) DNM3OS in SKOV3 ovarian cancer cells. Following siRNA-mediated knockdown of DNM3OS or non-targeting control, RNA-sequencing was performed. This high-throughput data revealed knockdown of DNM3OS down-regulated the expression of genes and pathways known to induce EMT in ovarian cancer.
Project description:The identification of prognostic biomarkers is a priority for patients suffering from high-grade serous ovarian cancer (SOC), which accounts for >70% of ovarian cancer (OC) deaths. Meanwhile borderline ovarian cancer (BOC) is a low malignancy tumor and usually patients undergo surgery with low probabilities of recurrence. However, SOC remains the most lethal neoplasm due to the lack of biomarkers for early diagnosis and prognosis. In this regard BORIS (CTCFL), a CTCF paralog, is a promising cancer biomarker that is overexpressed and controls transcription in several cancer types, mainly in OC. Studies suggest that BORIS has an important function in OC by altering gene expression, but the effect and extent to which BORIS influences transcription in OC from a genome-wide perspective is unclear. Here we sought to identify BORIS target genes in an OC cell line (OVCAR3) with potential biomarker use in OC tumor samples. To achieve this, we performed in vitro knockout (KO) and knockdown (KD) experiments of BORIS in OVCAR3 cell line followed by expression microarrays and bioinformatics network enrichment analysis to identify relevant BORIS target genes.
