(Submitter supplied) Multiple DNA methylation changes have been associated with the acquisition of drug resistance; however it remains uncertain how many of these changes may represent critical DNA methylation drivers of chemoresistance. Using genome-wide DNA methylation profiling across 27,578 CpG sites on Illumina HumanMethylation27 bead array we identified loci at 4092 genes becoming hypermethylated in the chemoresistant A2780/cp70 ovarian tumour cell line compared to the parental sensitive A2780 line. more...

(Submitter supplied) Multiple DNA methylation changes have been associated with the acquisition of drug resistance; however it remains uncertain how many of these changes may represent critical DNA methylation drivers of chemoresistance. Using gene expression profiling method on HGU133plus2 array, we identified a total of 1370 genes showing significant gene expression changes with 687 genes going up and 683 genes going down in the resistant (cp70) versus sensitive cell lines (A2780) by Rank Product (FDR<5%). more...

(Submitter supplied) Background: In high-grade serous ovarian cancer (HGSOC) intrinsic and/or acquired resistance against platinum-containing chemotherapy is a major obstacle for successful treatment. A low frequency of somatic mutations, but frequent epigenetic alterations including DNA methylation in HGSOC tumors, presents the cancer epigenome as a relevant target for innovative therapy. Patient-derived xenografts (PDXs) supposedly are good preclinical models for identifying novel drug targets. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is a fatal malignancy with a dismal prognosis. The recent advances in genomics and transcriptomics have led to large volumes of molecular data for HCC, providing an unprecedented opportunity to translate these data into more effective therapeutics. By creating HCC gene expression signatures and comparing with drug response signatures from multiple datasets, we identified four antihelminthics (from over 1000 FDA-approved drugs) that can reverse the HCC disease gene expression. more...

(Submitter supplied) We examined the transcriptional changes modulated by ESR2 agonist liquiritigenin by perfroming global transcriptome analysis. ES2 cells were treated with either vehicle or liquiritigenin for 24 h and the isolated RNA was utilized for RNA-seq analysis. Our results demonstrated that liquiritigenin modulated several genes that are involved in NF-kB signaling, inflammation, NRF2 mediated oxidative stress response, and MMP signaling.

(Submitter supplied) Carboplatin and paclitaxel are the most widely prescribed chemotherapeutic agents for ovarian cancer. Not all patients respond to treatment, so there is a need for biomarkers that reliably predict resistance in ovarian tumors. Expression of such biomarkers may be dynamically controlled. Gene expression was assessed for a period of 14 days after treatment with carboplatin or combined carboplatin-paclitaxel in xenografts from two ovarian cancer models: chemosensitive serous adenocarcinoma derived OV1002 and slow growing, chemoresistant HOX424 of clear cell origin. more...

(Submitter supplied) Menopausal estrogen (E2) replacement therapy increases the risk of estrogen receptor (ER)-positive epithelial ovarian cancers (EOC). Whether E2 is tumorigenic or promotes expansion of undiagnosed pre-existing disease is unknown. To determine E2 effects on tumor promotion, we developed an intraperitoneal mouse xenograft model using ZsGreen fluorescent ER- 2008 and ER+ PEO4 human EOC cells. Tumor growth was quantified by in vivo fluorescent imaging. more...

(Submitter supplied) To identify the gene signature accounting for the distinct clinical outcomes in ovarian clear cell cancer patients Clear cell ovarian cancer is an epithelial ovarian cancer histotype that is less responsive to chemotherapy and carries poorer prognosis than serous and endometrioid histotypes. Despite this, patients with these tumors are treated in a similar fashion as all other ovarian cancers. Previous genomic analysis has suggested that clear cell cancers represent a unique tumor subtype. more...

(Submitter supplied) The purpose of this study was to characterise the effects of trastuzumab and pertuzumab, either as single agents or as combination therapy on gene and protein expression in human ovarian cancer in vivo. Illumina BeadChips were used to profile the transcriptome after four days treatment of SKOV3 tumor xenografts. Although genes involved with HER2, MAP-kinase and p53 signaling pathways were commonly induced by all treatments, a greater number and variety of genes were differentially expressed by the complementary combination therapies compared to either drug on its own. more...

(Submitter supplied) Transcriptomic studies of human tumor xenografts are complicated by the presence of murine cellular mRNA. As such, it is useful to know the extent to which mouse mRNA cross-hybridizes to any given array platform. In this study, murine cDNA samples from diverse sources were hybridized to Affymetrix Human Genome U133 Plus 2.0 Arrays. In this regard it is possible to identify specific probes that are potential targets of cross-species interference.

(Submitter supplied) Xenograft models remain a cornerstone technology in the development of anti-cancer agents. The ability of immunocompromised rodents to support the growth of human tumors provides an invaluable transition between in vitro testing and clinical trials. Therefore, approaches to improve model selection are required. In this study, cDNA microarray data was generated for a collection of xenograft models at in vivo passages 1, 4 and 10 (P1, P4 and P10) along with originating cell lines (P0). more...
