Project description:Gene expression profiling was carried out HeyA8 and SKOV3-ip1 ovarian cancer cell lines, treated either with vehicle control or 10 uM norepinephrine. The primary research question is whether ovarian cancer cell gene expression differs as a function of norepinephrine exposure.

Project description:The purpose of this study is to understand the effects of adrenergic signaling on the transcriptome of cell line models postulated to be the cells of origin of epithelial ovarian cancers using RNA-Seq. Here we explored the effects of the stress-related hormone, norepinephrine, on normal human ovarian and fallopian tube surface epithelial cellss. We investigated the early transcriptional response to norepinephrine in normal immortalized ovarian surface epithelial cells and fallopian tube secretory cells. RNA-Seq data of treated and untreated cells were analyzed to identify genes with differential expression.

Project description:MicroRNA miRNA expression profiles for human ovarian carcinomas were examined to investigate the miRNA involvement in the development of this neoplasia. miRNA microarray analysis identified statistical unique profiles, which could discriminate ovarian carcinomas from noncancerous ovarian tissues, and different groups of tumors classified according to histo-pathological characteristics.

Project description:Background: The goal of this study was to determine the transcriptional consequences of norepinephrine transporter (NET) gene deletion in noradrenergic neuron differentiation. The norepinephrine transporter (NET) is the target of powerful mind-altering substances, such as tricyclic antidepressants and the drug of abuse, cocaine. NET function in adult noradrenergic neurons of the peripheral and central nervous systems is that of a scavenger that internalizes norepinephrine from the synaptic cleft. By contrast, norepinephrine (NE) transport has a different role in embryogenesis. It promotes differentiation of neural crest cells and locus ceruleus progenitors into noradrenergic neurons, whereas NET inhibitors, such as the tricyclic antidepressant desipramine and the drug of abuse, cocaine, inhibit noradrenergic differentiation. While NET structure und regulation of NET function is well described, little is known about downstream targets of NE transport. Results: We have determined by long serial analysis of gene expression (LongSAGE) the gene expression profiles of in vitro differentiating wild type and norepinephrine transporter-deficient (NETKO) neural crest derivatives. Comparison analyses with the wild type library (GSM 105765) have identified a number of important differentially expressed genes, including genes relevant to noradrenergic neuron differentiation and to the phenotype of NETKO mice. Furthermore we have identified novel differentially expressed genes. Conclusions: Loss of NET function during embryonic development deregulates signaling pathways that are critically involved in neural crest formation and noradrenergic neuron differentiation. The library was constructed from total RNA of 60 neural crest culture at culture day 7. The neural tubes were dissected from E9.5 embryos that lack the norepinephrine transporter gene.

Project description:Chronic stress is associated with hormonal alterations that are known to promote cancer progression. The stress hormone norepinephrine promotes migration and metastasis of prostate cancer cells. Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase which is phosphorylated during chronic stress or norepinephrine treatment. Here, we investigated how norepinephrine modulates the gene expression in Myc-CaP prostate cancer cell line. We also focused on the effect of FAK knockdown in norepinephrine-induced changes of the gene expression profile.

Project description:The goal of this study is to gain a better understanding of the transcriptional responses of M. hyopneumoniae under norepinephrine stress. Six independent RNA samples from norepinephrine-exposed cultures were paired with six independent RNA samples from control cultures for hybridization to six two-color microarrays. For three arrays, the control RNA sample was labeled with Cy3 dye and the experimental RNA sample was labeled with Cy5 dye, the dyes were reversed for the other three arrays to overcome dye bias.

Project description:Objective: Ovarian tumors of low-malignant potential (LMP) and low-grade serous ovarian carcinomas are thought to represent different stages on a tumorigenic continuum and to develop along pathways distinct from that of high-grade serous ovarian carcinoma. Past studies have utilized gene expression profiles to support this theory. The objective of the current study was to identify new genes whose expression profiles in LMP ovarian tumors and low-grade ovarian carcinomas differ from that in high-grade ovarian carcinomas. Methods: We used RNA from 3 normal human ovarian surface epithelia (HOSE) and from 10 low-grade and 10 high-grade serous ovarian carcinoma samples to perform gene expression profiling. Using real-time reverse-transcription polymerase chain reaction (RT-PCR), we evaluated changes in PAX2 mRNA expression in cDNA created from RNA extracted from an independent set of ovarian tissue samples (7 LMP tumors and 17 low-grade and 23 high-grade serous carcinomas). We also examined PAX2 expression using Western blot analysis of protein extracted from a set of ovarian LMP and low- and high-grade carcinoma tissue samples. Additionally, we used immunohistochemistry (IHC) to validate PAX2 overexpression in a third independent set of paraffin ovarian tissue sections from 17 LMP tumors and 16 low- and 257 high-grade carcinomas. Results: Gene profiling revealed higher expression of PAX2 in low-grade than in high-grade ovarian carcinomas. Real-time RT-PCR demonstrated a statistically significant difference in median PAX2 mRNA expression, expressed as fold change, among ovarian LMP tumor (1837.38), low-grade (183.12), and high-grade (3.72) carcinoma samples (p=0.015). Western blot analysis revealed strong PAX2 expression in ovarian LMP and low-grade carcinoma samples but no PAX2 protein expression in high-grade carcinomas. On IHC, more LMP tumor and low-grade carcinoma samples expressed moderate to high levels of PAX2 than did high-grade ovarian carcinoma samples. The numbers of samples with strong nuclear staining was significantly higher for ovarian LMP tumors (10 of 17, p<0.001) and low-grade serous carcinomas (10 of 16, p<0.001) than for high-grade carcinomas (27 of 257). Discussion: Our identification and validation of higher PAX2 expression in ovarian LMP tumors and low-grade serous carcinomas than in high-grade carcinomas supports the two-tiered hypothesis that the first two are on a continuum and are distinct from high-grade ovarian carcinomas. PAX2 may represent a potential biomarker and future therapeutic target for individualizing chemotherapy for ovarian LMP tumors and low-grade carcinomas in the future. Experiment Overall Design: We used RNA from 3 normal human ovarian surface epithelia (HOSE) and from 10 low-grade and 10 high-grade serous ovarian carcinoma samples to perform gene expression profiling. Using real-time reverse-transcription polymerase chain reaction (RT-PCR), we evaluated changes in PAX2 mRNA expression in cDNA created from RNA extracted from an independent set of ovarian tissue samples (7 LMP tumors and 17 low-grade and 23 high-grade serous carcinomas).
