Functional Analysis of PGRP-LA in Drosophila Immunity

Bruno Lemaitre, Juan Camilo Paredes Escobar

PeptidoGlycan Recognition Proteins (PGRPs) are key regulators of the insect innate antibacterial response. Even if they have been intensively studied, some of them have yet unknown functions. Here, we present a functional analysis of PGRP-LA, an as yet unc ...

Identification of HMX1 target genes: A predictive promoter model approach

Purpose: A homozygous mutation in the H6 family homeobox 1 (HMX1) gene is responsible for a new oculoauricular defect leading to eye and auricular developmental abnormalities as well as early retinal degeneration (MIM 612109). However, the HMX1 pathway rem ...

Mapping the fine structure of a eukaryotic promoter input-output function

Sebastian Maerkl, Nicolas Dénervaud, Arun Stephen Rajkumar

The precise tuning of gene expression levels is essential for the optimal performance of transcriptional regulatory networks. We created 209 variants of the Saccharomyces cerevisiae PHO5 promoter to quantify how different binding sites for the transcriptio ...

Nuclear Factor I genomic binding associates with chromatin boundaries

Giovanni Dietler, Philipp Bucher, Giovanna Ambrosini, Nicolas Mermod, Petar Pjanic

Background: The Nuclear Factor I (NFI) family of DNA binding proteins (also called CCAAT box transcription factors or CTF) is involved in both DNA replication and gene expression regulation. Using chromatin immuno-precipitation and high throughput sequenci ...

Systematic Analysis of Yeast Gene Expression by Synthetic Promoter Libraries

Arun Stephen Rajkumar

The precise tuning of gene expression levels is essential for optimal performance of transcriptional regulatory networks. Many regulatory components control promoter output, but transcription factor (TF) binding sites are amongst the most prominent. Beside ...

Spot Identification and Quality Control in Cell-Based Microarrays

Blaise Calpe

Cell-based microarrays are being increasingly used as a tool for combinatorial and high throughput screening of cellular microenvironments. Analysis of microarrays requires several steps, including microarray imaging, identification of cell spots, quality ...

Comparative analyses of Purkinje cell gene expression profiles reveal shared molecular abnormalities in models of different polyglutamine diseases

Polyglutamine (PolyQ) diseases have common features that include progressive selective neurodegeneration and the formation of protein aggregates. There is growing evidence to suggest that critical nuclear events lead to transcriptional alterations in PolyQ ...

Personal receptor repertoires: olfaction as a model

Sebastian Martin Waszak

Background: Information on nucleotide diversity along completely sequenced human genomes has increased tremendously over the last few years. This makes it possible to reassess the diversity status of distinct receptor proteins in different human individual ...
