Chronic obstructive pulmonary disease (COPD) is the 5(th) most prevalent disease worldwide leading to severe morbidity and mortality in developed countries. The disease is strongly associated with smoking, and can be characterized by progressive and irreve ...
The class II trans-activator CIITA is a transcriptional co-activator required for the expression of Major Histocompatibility Complex (MHC) genes. Although the latter function is well established, the global target-gene specificity of CIITA had not been def ...
Background: Proteins are the primary regulatory agents of transcription even though mRNA expression data alone, from systems like DNA microarrays, are widely used. In addition, the regulation process in genetic systems is inherently non-linear in nature, a ...
Serpins, a superfamily of protease inhibitors, control proteolytic cascades in many physiological processes. Genomic studies have revealed the presence of a high number of serpin-encoding genes in Drosophila melanogaster, but their functions remain largely ...
Recently the sequencing project of the human genome has been completed. The interest of the post-sequencing-era is shifting nowadays towards the investigation of the biological function and localization of the encoded proteins. Proteins are essential parts ...
This tutorial paper considers the problem of reconstructing Genetic Regulatory Networks (GRNs) from gene expression measurements. Among various modeling frameworks that have been proposed for these biological systems, we focus on PieceWise Affine (PWA) mod ...
INTRODUCTION: About 70% of breast cancers express oestrogen receptor alpha (ESR1/ERalpha) and are oestrogen-dependent for growth. In contrast with the highly proliferative nature of ERalpha-positive tumour cells, ERalpha-positive cells in normal breast tis ...
BACKGROUND: The Affymetrix technology is nowadays a well-established method for the analysis of gene expression profiles in cancer research studies. However, changes in gene expression levels are not the only way to link genes and disease. The existence of ...
The zebrafish (Danio rerio) embryo toxicity test (DarT) is under consideration as an alternative to the acute fish toxicity test. Microscopically visible developmental disorders or death are the endpoints used to report on toxicity in DarT. These endpoints ...
Ants display a range of fascinating behaviors, a remarkable level of intra-species phenotypic plasticity and many other interesting characteristics. Here we present a new tool to study the molecular mechanisms underlying these traits: a tentatively annotat ...
