Gene expression profiling of a CpG-ODN-dependent antiviral system in RAW 264.7 cells.
Written in English
CpG-oligodeoxynucleotides (CpG-ODN) confer local antiviral properties when delivered to the genital mucosa of mice. CpG-ODN treatment also prevents the replication of the herpes simplex virus 2 (HSV-2) in the murine macrophage cell-line RAW 264.7. We hypothesized that this CpG-dependent antiviral system is the result of alterations in gene expression. In this study we used high density cDNA and oligonucleotide microarrays to survey the gene expression of the mouse genome over seven time points within a 24h period in order to elucidate a program of genes responsible for the antiviral effect. We used hierarchical and/or K-means clustering to reveal similarly regulated genes. Interferon-related genes including Stat-1 and -2, IRF-3 and -7, and several members of the powerful antiviral oligoadenylate synthetase (OAS) family were regulated by CpG-ODN. We also inhibited NFkappaB activation and showed that CpG-dependent cytokine secretion requires NFkappaB, but that the antiviral effect persists independently of NFkappaB activity.

Purpose: Although the central role of the immune system for tumor prognosis is generally accepted, a single robust marker is not yet available. Experimental Design: On the basis of receiver operating characteristic analyses, robust markers were identified from a gene B cell–derived metagene and analyzed in gene expression profiles of 1, breast cancer; 1, non–small cell lung.

Abstract. Cardiotoxicity is one of the leading causes of drug attrition. Current in vitro models insufficiently predict cardiotoxicity, and there is a need for alternative physiologically relevant models. Here we describe the gene expression profile of human-induced pluripotent stem cell–derived cardiocytes (iCC) postthaw over a period of 42 days in culture and compare this profile to human. Gene Expression Profiling. Identifying Cell-Specific Transcripts More is known about the cellular architecture and development of C. elegans than of any other metazoan. For example, the lineal origin and morphology of all somatic cells are fully established. In addition, a wiring diagram traces every synapse among the neurons in the worm nervous system.

DNA arrays are the most, common gene expression profiling technology. A DNA array consists of a solid support, (nylon membrane, glass chip) that carries DNA sequences representing genes - the probes. In hybridization experiments with the target sample of labeled complementary ribonucleic acids (cRNAs) and through subsequent data, capture a Cited by: “This beautifully illustrated book on gene expression profiling provides detailed protocols for a broad range of techniques for the analysis of gene expression at the DNA, RNA, and protein levels.
Although written for researchers, the book will be helpful for graduate students and others interested in learning about gene expression.

Objective To identify differentially expressed genes in peripheral blood mononuclear cells (PBMCs) from patients with ankylosing spondylitis (AS) compared with healthy individuals. Methods RNA was extracted from PBMCs collected from 18 patients with active disease and 18 gender-matched and age-matched controls.
Expression profiles of these cells were determined using by: Figure 2. Innate immune activation as measured by NF-κB activity and cytokine producing dendritic cells.

These cells respond to various abnormal conditions such as viral. Gene expression analysis simultaneously compares the RNA expression levels of multiple genes (profiling) and/or multiple samples (screening).
This analysis can help scientists identify the molecular basis of phenotypic differences and to select gene expression targets for in-depth study.

Objective Gene expression profiling provides an opportunity to develop robust prognostic markers of colorectal carcinoma (CRC). However, the markers have not been applied for clinical decision making.
We aimed to develop an immunohistochemistry signature using microarray data for predicting CRC prognosis. Design We evaluated 25 CRC gene signatures in independent microarray datasets with. In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular profiles can, for example, distinguish between cells that are actively dividing, or show how the cells react to a particular treatment.
The strategy of gene-expression profiling was considered to be noninferior to the strategy of routine biopsies if the one-sided upper boundary of the 95% confidence interval for the hazard ratio.
The expression level of the target gene was standardised with that of the house-keeping beta-actin gene and the ratio of each gene expression in paired samples (adenoma or adenocarcinoma/adjacent. Prostate cancer, a leading cause of cancer death, displays a broad range of clinical behavior from relatively indolent to aggressive metastatic disease.
To explore potential molecular variation underlying this clinical heterogeneity, we profiled gene expression in 62 primary prostate tumors, as well as 41 normal prostate specimens and nine lymph node metastases, using cDNA. Mutations in the gene encoding emerin cause Emery-Dreifuss muscular dystrophy (EDMD), a disorder causing progressive skeletal muscle wasting, irregular heart rhythms and contractures of major tendons.
