This study aimed to define a gene expression profile associated with response to anti-estrogen treatment in estrogen receptor alpha (ERalpha)-positive breast cancer from elderly patients and to identify possible candidate genes associated with resistance by detecting those modulated by treatment. Using cDNA microarrays containing 16 702 unique clones, 21 pre-treatment and 11 paired post-treatment samples collected in a neo-adjuvant toremifene trial on elderly patients with operable and locally a ...[more]

Transcription profiling of human breast cancer samples kept at room temperature for different lengths of time before freezing

Project description:In order to gain awareness of the gene expression artifacts linked to improper tissue handling also for this particular type of neoplasia, we have investigated gene expression profiles in a set of primary breast tumors, grossly subdivided into 4 aliquots and kept at room temperature for 0, 2, 6 and 24 hours after resection and before snap-freezing in liquid nitrogen.

Genetic regulators of large-scale transcriptional signatures in cancer

Project description:Gene expression signatures encompassing dozens to hundreds of genes have been associated with many important parameters of cancer, but mechanisms of their control are largely unknown. Here we present a method based on genetic linkage that can prospectively identify functional regulators driving large-scale transcriptional signatures in cancer. Using this method we show that the wound response signature, a poor-prognosis expression pattern of 512 genes in breast cancer, is induced by coordinate amplifications of MYC and CSN5 (also known as JAB1 or COPS5). This information enabled experimental recapitulation, functional assessment and mechanistic elucidation of the wound signature in breast epithelial cells. A cell type comparison design experiment design type compares cells of different type for example different cell lines. Computed

Microarray analysis of pig innate immune responses after experimental infection with Actinobacillus pleuropneumoniae

Project description:To study hepatic gene expression differences, liver samples from infected pigs (n = 10) were compared with liver samples from the non-infected control group (n = 5). Ten microarrays were performed, such that 5 randomly selected cDNA samples from the infected group were labeled with Oyster 550 (Genisphere Inc., Hatfield, PA, USA) and compared directly to 5 control animals labeled with Oyster 650 (Genisphere) analysing a pair of samples (one from an infected animal and one from a randomly chosen non-infected animal) on each microarray slide. The remaining five cDNA preparations from the infected group were labeled with Oyster 650 and compared in the same way to the five controls labeled with Oyster 550 on the remaining 5 microarray slides. This dye-swap design was applied to reduce variation due to dye effects and to provide as much biological replication as possible. Keywords: Disease state analysis Two-condition experiment, Disease vs. Control, Biological replicates: 10 disease replicates and 5 control replicates, 10 Microarrays comparing one disease replicate with one control replicate.

Evidence of the role of tick subolesin in gene expression

Project description:Subolesin is an evolutionary conserved protein that was recently discovered in Ixodes scapularis as a tick protective antigen and has a role in tick blood digestion, reproduction and development. In other organisms, subolesin orthologs may be involved in the control of developmental processes. Because of the profound effect of subolesin knockdown in ticks and other organisms, we hypothesized that subolesin has a role in gene expression, thus affecting multiple cellular processes. The objective of this study was to provide support for the role of subolesin in gene expression. Keywords: time course Total RNA was prepared and pooled from subolesin dsRNA- and saline-injected ticks at 6 and 9 dpi (5 and 8 days of feeding).

KP1019 (trans-[tetrachlorobis(1H-indazole) ruthenate(III)]) Dependent Transcription in WT Saccharomyces cerevisiae

Project description:To characterize cellular response to the anti-cancer ruthinium complex KP1019, budding yeast Saccharomyces cerevisiae transcripitonal response to KP1019 was measured using microarray analysis. Although KP1019 molecular mechanism of action remains a matter of debate, the drug has been shown to bind DNA in biophysical assays and to damage DNA of colorectal and ovarian cancer cells in vitro. KP1019 has also been shown to induce mutations and induce cell cycle arrest in Saccharomyces cerevisiae, suggesting that budding yeast can serve as an appropriate model for characterizing the cellular response to the drug. Here we use a transcriptomic approach to characterize KP1019 induced transcriptional changes. Two concentrations of KP1019 (40 micrograms/mL and 80 micrograms/ml were assayed by microarray analysis to obtain comparative expression data for treated and untreated cells of the budding yeast Saccharomyces cerevisiae (strain BY4741). Two biological replicates of each concentration were done. Each biological replicate was done in duplicate to allow for dye reversal controls.

Prostate miRNA expression profiles

Project description:Comparison of miRNA expression profiles in normal and malignant prostate tissues. Keywords: microarray analysis of microRNA expression profiles MicroRNA expression was compared between normal prostate tissue from either young subjects that died of trauma, or normal adjacent to tumor, and prostatic tumors in older prostate cancer patients. RNA was isolated from frozen tissue sections, enriched for the miRNA fraction, which was subsequently labeled and hybridized to miRNA microarrays for expression profiling analysis.
