Influence of gene copy number on self-regulated gene expression.
Using an analytically solvable stochastic model, we study the properties of a simple genetic circuit consisting of multiple copies of a self-regulating gene. We analyse how the variation in gene copy number and the mutations changing the auto-regulation strength affect the steady-state distribution of protein concentration. We predict that one-reporter assay, an experimental method where the ex...
متن کاملCopy number variants, diseases and gene expression.
Copy number variation (CNV) has recently gained considerable interest as a source of genetic variation likely to play a role in phenotypic diversity and evolution. Much effort has been put into the identification and mapping of regions that vary in copy number among seemingly normal individuals in humans and a number of model organisms, using bioinformatics or hybridization-based methods. These...
متن کاملSupervised classification of combined copy number and gene expression data
In this paper we apply a predictive profiling method to genome copy number aberrations (CNA) in combination with gene expression and clinical data to identify molecular patterns of cancer pathophysiology. Predictive models and optimal feature lists for the platforms are developed by a complete validation SVM-based machine learning system. Ranked list of genome CNA sites (assessed by comparative...
متن کاملEvaluation of HER2, MDM2, MYC, MET and TP53 gene copy number alterations in gastric cancer patients
Background: Gastric cancer (GC) is considered as one of the most common types of cancer worldwide with poor prognosis and generally limited treatment options. Recent studies have indicated that HER2, MDM2, MYC, MET, and TP53 play an important role in the development of gastric cancer. Therefore, the aim of this study was to evaluate the incidence of amplification/deletion of these genes in pati...
متن کاملGlutathione S-transferase copy number variation alters lung gene expression.
The glutathione S-transferase (GST) enzymes catalyse the conjugation of xenobiotics to glutathione. Based on reports that inherited copy number variations (CNVs) modulate some GST gene expression levels, and that the small airway epithelium (SAE) and alveolar macrophages (AMs) are involved early in the pathogenesis of smoking-induced lung disease, we asked: do germline CNVs modulate GST express...
