Previous environmental surveys of eukaryotic diversity using the small subunit ribosomal RNA (SSU rRNA) gene have revealed many clone sequences that branch near the base of Fungi. In this work, we demonstrate that many of these sequences, including those o ...
Forkhead/winged-helix transcription factors are evolutionarily conserved and found in organisms as diverse as yeast and humans. They regulate a broad spectrum of events during embryonic and post natal development, including cell cycle regulation, survival, ...
Gene transfer methods for producing recombinant cell lines are often not very efficient. One reason is that the recombinant DNA is delivered into the cell cytoplasm and only a small fraction reaches the nucleus. This chapter describes a method for microinj ...
Recombinant protein-based biologics are increasingly relevant in the pharmaceutical industry. Currently, mammalian cell-based bioprocesses are a routine manufacturing procedure for complex proteins such as recombinant antibodies, and the number of new biol ...
Homing endonucleases (HE) are double-stranded DNAses that target large recognition sites (12-40 bp). HE-encoding sequences are usually embedded in either introns or inteins. Their recognition sites are extremely rare, with none or only a few of these sites ...
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 purpose of this review is to describe the current status and to highlight several emerging trends in the manufacture of recombinant therapeutic proteins in cultivated mammalian cells. focusing on Chinese hamster ovary cells as the major production host ...
Ex vivo gene therapy is an interesting alternative to orthotopic liver transplantation (OLT) for treating metabolic liver diseases. In this study, we investigated its efficacy and biosafety in nonhuman primates. Hepatocytes isolated from liver lobectomy we ...
The forthcoming arrival on the market of numerous protein therapeutics that require high clinical doses will foster the need for high-producing mammalian cell lines. Furthermore, pressures to reduce the development time for new therapeutics has meant more ...
Transient transfection allows for fast production of recombinant proteins. However, the current bottlenecks in transient transfection are low titers and low specific productivity compared to stable cell lines. Here, we report an improved transient transfec ...
