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

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, Yang Liu

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, Samuel Neuenschwander, Ioannis Xenarios

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 ...

Reduction of Abeta amyloid pathology in APPPS1 transgenic mice in the absence of gut microbiota

Theo Lasser, Tristan Bolmont, Taoufiq Harach, Nicolas Jean Marc Antoine Duthilleul

Alzheimer’s disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number o ...

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- ...

Caged luciferin probes for the bioluminescence imaging of nitroreductase and hydrogen sulfide in living animals

Anzhelika Vorobyeva

Molecular imaging advances our understanding of cellular and molecular functions within complex biological systems. The development of novel imaging probes that can be applied to answer fundamental biological questions, diagnose and monitor disease progres ...

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

Davide Demurtas, Marc Moniatte, Adrian Schmid, Cyntia De Piano, Nikita Rudinskiy, 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 ...

Study of transposon-mediated cell pool and cell line generation in CHO cells

Sowmya Balasubramanian

The goal of this thesis was to evaluate the use of artificial transposon systems for the generation of recombinant cell pools and cell lines with Chinese hamster ovary (CHO) cells as the production host. Transposons are naturally occurring genetic elements ...

Optogenetic Dissection of the Basal Forebrain Neuromodulatory Control of Cortical Activation, Plasticity, and Cognition

Carl Petersen

The basal forebrain (BF) houses major ascending projections to the entire neocortex that have long been implicated in arousal, learning, and attention. The disruption of the BF has been linked with major neurological disorders, such as coma and Alzheimer's ...

Intracerebroventricular Injection of Adeno-Associated Virus 6 and 9 Vectors for Cell Type-Specific Transgene Expression in the Spinal Cord

Patrick Aebischer, Bernard Schneider, Elisabeth Anne Dirren, Christopher Towne, Veronica Setola

In the context of motoneuron diseases, gene delivery as an experimental or therapeutic approach is hindered by the challenge to specifically target cell populations that are widely distributed along the spinal cord. Further complicating the task, transgene ...
