Comparative Enumeration Gene Expression
نویسنده
چکیده
This paper is about differential gene expression measured by transcript counting methods such as SAGE or MPSS. It introduces two significance tests for detection of differential expressed tags: frequentist and Bayesian. Under the frequentist view, it is proposed a test that computes the critical level as a function of each tag total frequency. Under the Bayesian view the Full Bayesian Significance Test is used considering the logistic normal distribution. The two proposed significance levels, the frequentist and the Bayesian, are compared for a data set with four libraries. The linking function between them is a Beta distribution function with mean 0.39 and standard deviation 0.30.

Evaluation of β-actin as a Reference Gene for Comparative Expression Analysis of Equine Adipose- and Bone Marrow-Derived Mesenchymal Stem Cells by qRT-PCR
Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data. This study was designed to e...

The gene encoding the human basic fibroblast growth factor (hbFGF) has been already chemically-synthesized and cloned in pET-3a expression vector (Pasteur Institute of Iran). In the present study, we compared the level of expression of this synthetic hbFGF and its related cDNA in Escherichia coli. The pBR322-cDNA of hbFGF supplied by Dr. Seno (from Molecular Biology Dept, Okaido prefectural uni...

متن کاملComparative Analysis of Expression of Chemokoine Receptors CXCR4, CXCR6, CCR1 and CX3CR in Human Adipose-Drived Mesenchymal Stem Cell with Valproic Acid
Introduction: Chemokine receptors are found on the surface of stem cells. There have been 19 distinct chemokine receptors described in mammals. Chemokines are major players in migration and homing. Therefore, changes in their levels or function can help us to increase the migratory potential of these cells. Valproic acid differs in structure from other drugs in common use. The way in which Va...
متن کاملGene Expression and Promoter Methylation Status of VHL, Runx-3, E-cadherin, P15 and P16 Genes During EPO-Mediated Erythroid Differentiation of CD34+ Hematopoietic Stem Cells
Background: VHL (von Hippel-Lindau), Runx-3 (Runt-related transcription factor 3), E-cadherin (Epithelial cadherin), P15 (INK4a, cyclin dependent kinase inhibitor), and P16 (INK4b) genes are essential in hematopoiesis. The aim of this study was to explore the correlation between gene expression and promoter methylation in CD34+ stem cells before and after differentiation to erythroid lineage. M...
