Quantitative characterization of the inorganic phosphate gene regulatory networks in S. cerevisiae and bottom up engineering an orthogonal gene network

Gene regulatory networks (GRNs) play a crucial role in an organism's response to changing environmental conditions. Cellular behaviors typically result from the integration of multiple gene outputs, and their regulation often demands precise control of num ...

Telomere protection against oxidative stress

Thu Trang Nguyen

Telomeres are nucleoprotein structures at the ends of linear chromosomes, being essential for the maintenance of genomic integrity. Telomeres have a unique structure which distinguishes chromosome termini from DNA damage sites. Shelterin complexes are the ...

Hyperplectonemes: A Higher Order Compact and Dynamic DNA Self-Organization

Giovanni Dietler, Paolo De Los Rios, Giovanni Longo, Fabrizio Benedetti, Aleksandre Japaridze

Bacterial chromosome has a compact structure that dynamically changes its shape in response to bacterial growth rate and growth phase. Determining how chromatin remains accessible to DNA binding proteins, and transcription machinery is crucial to understan ...

An automated microreactor for semi-continuous biosensor measurements

Philippe Renaud, Harald Van Lintel, Nina Buffi

Living bacteria or yeast cells are frequently used as bioreporters for the detection of specific chemical analytes or conditions of sample toxicity. In particular, bacteria or yeast equipped with synthetic gene circuitry that allows the production of a rel ...

Effects of physiological self-crowding of DNA on shape and biological properties of DNA molecules with various levels of supercoiling

Giovanni Dietler, Yannis Burnier, Julien Dorier, Fabrizio Benedetti, Aleksandre Japaridze

DNA in bacterial chromosomes and bacterial plasmids is supercoiled. DNA supercoiling is essential for DNA replication and gene regulation. However, the density of supercoiling in vivo is circa twice smaller than in deproteinized DNA molecules isolated from ...

Mathematical models and computational methods for the analysis of genome-scale protein synthesis

Julien Racle

Proteins are a ubiquitous and indispensable element for every living organism, from simple bacteria to mammals. Already in the simplest organisms, there exist some thousands of different protein species that take up a great variety of structures, and thus ...

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 ...

TransFLP - A Method to Genetically Modify Vibrio cholerae Based on Natural Transformation and FLP-recombination

Melanie Blokesch

Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...

A Novel Yeast-Based Platform for Small Molecule Target Deconvolution Reveals Previously Unknown Binding Partners for the Approved Drugs Erlotinib, Atorvastatin, and Sulfasalazine

Christopher Chidley

The identification of all protein targets of a small molecule drug, i.e. target deconvolution, provides the basis for understanding its beneficial or deleterious actions. Target deconvolution remains a major and often problematic task within the biotechnol ...

Identification of genetic insulator elements to increase the safety of viral gene therapy vectors

Haematopoeitic system diseases, both acquired and inherited, can be currently cured by allogeneic haematopoietic stem cell transplantation. This treatment provides highly successful immune function recovery for patients receiving grafts of HLA-compatible d ...

DCJ median problems on linear multichromosomal genomes: Graph representation and fast exact solutions

Given a set of genomes g and a distance measure d, the genome rearrangement median problem asks for another genome q that minimizes Sigma n is an element of g(d(q,g)). This problem lies at the heart of phylogenetic reconstruction from rearrangement data. w ...

Long-range enhancer-promoter interactions in the HoxD complex

Denis Duboule

Collinear expression of 5′ Hoxd genes during mammalian limb development is required to properly determine digits number and identity. We recently proposed a two-step model to account for the underlying regulatory mechanism, which involves an initial loopin ...

Development of high-titer transient gene expression processes for manufacturing recombinant proteins

Gaurav Backliwal

The market for recombinant therapeutic proteins (including antibodies) is estimated to be greater than $50-billion and has a compounded annual growth rate of around 20%. More than 50% of all approved processes for manufacturing recombinant proteins use mam ...

Control of M. tuberculosis ESAT-6 secretion and specific T cell recognition by PhoP

Stewart Cole

Analysis of mycobacterial strains that have lost their ability to cause disease is a powerful approach to identify yet unknown virulence determinants and pathways involved in tuberculosis pathogenesis. Two of the most widely used attenuated strains in the ...

BTA, a novel reagent for DNA attachment on glass and efficient generation of solid-phase amplified DNA colonies

Gerardo Turcatti

The tricarboxylate reagent benzene-1,3,5-triacetic acid (BTA) was used to attach 5'-aminated DNA primers and templates on an aminosilanized glass surface for subsequent generation of DNA colonies by in situ solid-phase amplification. We have characterized ...
