How are cells instructed to form somite boundaries by the zebrafish segmentation clock?

Olivier François Venzin

In vertebrate embryos, the elongating body axis is patterned via the sequential and rhyth-mic production of segments from a posterior unsegmented tissue called the presomitic mesoderm (PSM). This process is controlled by a population of cellular oscillator ...

Generation of a Gal4-dependent gene recombination and illuminating mouse

Freddy Radtke

Cell labeling technologies, including the Cre/loxP system, are powerful tools in developmental biology. Although the conventional Cre/loxP system has been extensively used to label the expression of specific genes, it is less frequently used for labeling p ...

Parkinson mice show functional and molecular changes in the gut long before motoric disease onset

Hilal Lashuel

Background: There is increasing evidence that Parkinson's disease (PD) might start in the gut, thus involving and compromising also the enteric nervous system (ENS). At the clinical onset of the disease the majority of dopaminergic neurons in the midbrain ...

Functional de novo Protein Design for Targeted Vaccines and Synthetic Biology Applications

Che Yang

Evolution has created, selected and evolved large repertoires of proteins that operate in various biological systems. Nowadays biotechnological needs are coming up orders of magnitude faster than proteins naturally evolve. The emergence of de novo protein ...

MAR-Mediated transgene integration into permissive chromatin and increased expression by recombination pathway engineering

Christian Iseli, Nicolas Mermod, Thomas Junier

Untargeted plasmid integration into mammalian cell genomes remains a poorly understood and inefficient process. The formation of plasmid concatemers and their genomic integration has been ascribed either to non-homologous end-joining (NHEJ) or homologous r ...

Multigene expression in stable CHO cell pools generated with the piggyBac transposon system

Florian Maria Wurm, David Hacker, Sowmya Balasubramanian

Heterogenous populations of recombinant cells (cell pools) stably expressing 1-4 transgenes were generated from Chinese hamster overy (CHO) cells with the piggyBac (PB) transposon system. The cell pools produced different combinations of three model protei ...

Recombinant protein production from stable mammalian cell lines and pools

David Hacker, Sowmya Balasubramanian

We highlight recent developments for the production of recombinant proteins from suspension-adapted mammalian cell lines. We discuss the generation of stable cell lines using transposons and lentivirus vectors (non-targeted transgene integration) and site- ...

Amyloid-beta oligomerization is associated with the generation of a typical peptide fragment fingerprint

Davide Demurtas, Adrian Schmid, Cyntia De Piano, Marc Moniatte, Christophe Fuerer

Amyloid-beta (A beta) peptide oligomerization plays a central role in the pathogenesis of Alzheimer's disease (AD), and A beta oligomers are collectively considered an appealing therapeutic target for the treatment of AD. However, the molecular mechanisms ...

Rapid recombinant protein production from piggyBac transposon-mediated stable CHO cell pools

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Zuzana Kadlecova, Sowmya Balasubramanian

Heterogeneous populations of stably transfected cells (cell pools) can serve for the rapid production of moderate amounts of recombinant proteins. Here, we propose the use of the piggyBac (PB) transposon system to improve the productivity and long-term sta ...

Transcriptional and post-transcriptional limitations of high-yielding, PEI-mediated transient transfection with CHO and HEK-293E cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak

Transient gene expression (TGE) in human embryonic kidney (HEK-293) and Chinese hamster ovary (CHO) cells is a well-established technology for the rapid generation of recombinant proteins. Although the maximum TGE yields have reached 1 g/L or more, the amo ...
