Natural competence of the pathogen Acinetobacter baumannii: an elusive phenomenon

Natural competence for transformation is an important driver of horizontal DNA exchange between different organisms. This can result in accumulation of dangerous genetic features, such as antibiotic resistance genes, in a single organism. One example of an ...

Chromatin Proteomics to Study Epigenetics - Challenges and Opportunities

Guido Van Mierlo

Regulation of gene expression is essential for the functioning of all eukaryotic organisms. Understanding gene expression regulation requires determining which proteins interact with regulatory elements in chromatin. MS-based analysis of chromatin has emer ...

Computational study of transcription factor binding sites

Romain Fernand Pietro Groux

Any living organism contains a whole set of instructions encoded as genes on the DNA. This set of instructions contains all the necessary information that the organism will ever need, from its development to a mature individual to environment specific resp ...

The PhoP-Dependent ncRNA Mcr7 Modulates the TAT Secretion System in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Swapna Uplekar, Jacques Rougemont, Andrej Benjak

The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead ...

The response of Desulfotomaculum reducens MI-1 to U(VI) exposure: a transcriptomic study

Rizlan Bernier-Latmani, Elena Cristina Dalla Vecchia

Desulfotomaculum reducens is the first Gram-positive sulfate- and metal-reducing bacterium for which the transcriptomic response to uranium exposure has been evaluated. The genes upregulated during fermentative growth in the presence of U(VI) as compared t ...

Transient recombinant protein expression in mammalian cells : the role of mRNA level and stability

Sarah Wulhfard

Transient gene expression (TGE) is a rapid method for generating recombinant proteins in mammalian cells, but the volumetric productivities for secreted proteins in transiently transfected CHO DG44 cells are typically more than an order of magnitude lower ...

The use of RNA interference to increase PEI-mediated transient gene expression in mammalian cells

Martin Bertschinger

DNA uptake by polyethylenimine (PEI)-mediated transfection was investigated in Chinese hamster ovary (CHO DG44) cells. Rapid DNA uptake was observed with the maximum occurring during the first 45-60 min after addition of PEI-DNA complexes to cells. With lo ...

Transient gene expression in suspension HEK-293 cells: application to large-scale protein production

Philippe Pierre Girard, Florian Maria Wurm, Lucia Baldi Unser, Natalie Muller

Recent advances in genomics, proteomics, and structural biology raised the general need for significant amounts of pure recombinant protein (r-protein). Because of the difficulty in obtaining in some cases proper protein folding in bacteria, several method ...
