Here we describe a simplified method for transient gene expression (TGE) in suspension-adapted Chinese hamster ovary (CHO) cells using polyethylenimine (PEI) for DNA delivery. Both the transfection and production phases of the bioprocess were performed at ...
This is a crucial transition time for human genetics in general, and for HIV host genetics in particular. After years of equivocal results from candidate gene analyses, several genome-wide association studies have been published that looked at plasma viral ...
Short-hairpin RNA (shRNA)-mediated gene knockdown is a powerful tool for targeted gene silencing and an emerging novel therapeutic strategy. Recent publications, however, reported unexpected toxicity after utilizing viral-mediated shRNA knockdown in vivo. ...
Mammalian cells in bioreactors as production host are the focus of this review. We wish to briefly describe today's technical status and to highlight emerging trends in the manufacture of recombinant therapeutic proteins, focusing on Chinese hamster ovary ...
Vertebrate embryos faithfully produce bilaterally symmetric somites that give rise to repetitive body structures such as vertebrae and skeletal muscle. Body segmentation is regulated by a cyclic gene expression system, containing the Delta-Notch pathway an ...
RNA interference has become an increasingly important tool for all aspects of molecular biology. Nevertheless, there is a technological challenge for performing gene knock-down with chemical transfection agents, as many relevant cell types are refractory t ...
A major challenge in neurological gene therapy is delivery of the transgene to sufficient cell numbers in an atraumatic manner. This is particularly difficult for motor neuron (MN) diseases that have cells located across the entire spinal cord, brain stem, ...
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 ...
Brain structure and function are determined in part through experience and in part through our inherited genes. A powerful approach for unravelling the balance between activity-dependent neuronal plasticity and genetic programs is to directly manipulate th ...
Drug-inducible systems allowing the control of transgene expression and knockdown in mammalian cells are invaluable tools for genetic research, and could also play important roles in translational research or gene therapy. We and others have developed a le ...
