Session 1: Expression System Design
9:00 - 12:00
Chair: Kenneth Lundstrom Flamel Technologies Vénissieux France
Co-chair: Mike Betenbaugh John Hopkins University Baltimore USA

Expression system design involves the optimization of expression vectors at the molecular level to bring about desirable downstream effects at the cellular level. The technologies presented here are targeted to the engineering of mammalian or insect cell expression vectors. The molecular basis of stable expression will be discussed as one of the key aspects of ensuring high quality protein production and reproducibility. Translational control is also important for further improvement in the enhancement of productivity. Furthermore, the choice of promoter has a significant effect on protein expression. The question concerns not only the strength of promoter activity as for many expression systems cell type specific and time-dependent (early and late) promoters exist. Closely related to promoters is the issue of generating inducible expression systems. The advantage of this approach is that expression can be turned on and off in a controlled manner to maximize protein production. Additionally, the session will deal with site-specific integration and insulators. In the context of engineering stable cell lines it has become evident that the chromosomal integration site plays an important role for construct stability and expression levels. Introduction of insulator sequences or matrix attachment regions have a strong influence on stability and protein production.

The topics of the Short Talk Session is a good indication of the diversity of topics presented at the PEACe meeting. The oral presentations were selected by the Scientific Organizing Committee from submitted abstracts with the following intentions:

o Enhance active participation of delegates
o Provide the opportunity for younger scientists to present their data
o Improve information exchange in a cross-field manner

The session will include presentation on cell engineering, vector engineering, improvement of cell culture conditions and enhanced recombinant protein production. Drosophila melanogaster S2 cells were used for enhanced recombinant production of Rabies virus glycoprotein through the control of culture conditions (Swiech, Brazil). Furthermore, the influence of oxygen concentration on the performance of S2 cells will be described (Batista, Brazil). Cell engineering by introduction of anti-apoptotic genes in relation to production will also be presented (Nivitchanyong, USA). A genomics approach for the identification of endogenous CHO promoter elements will be discussed (Pontiller, Austria). Additionally, Dr. Puchacz (USA) will present the use of the UCOE (Ubiquitous Chromatin Opening Elements) gene expression technology for protein production. Engineering of CHO-K1 cells to improve Baculovirus-based expression in mammalian cells will also be described (Clay, USA). Moreover, the session will contain talks on enhancing antibody expression in CHO cells by using chromatin remodeling elements (Saunders, UK) and the Gene Stripper system for the FACS selection of protein producing clones (Zang-Gander, USA).

Session III: Cell Engineering Session 8:30 -12:45
Chair: Mark Smales University of Kent Canterbury U.K.
Co-chair: Andy Racher Lonza Biologics Slough Berkshire U.K.

Cell engineering is considered as any manipulation that results in some change to the cell of interest. The subjects and topics within the area of cell engineering are wide, covering a diverse range of topics including, but not limited to, stem cell research, metabolic engineering, the up-regulation/knockdown(out) of target genes and proteins, the development of new cell lines and media, and many other topics besides. As suchcell engineering could be considered a seamless subject that transcends into many other areas, lying directly at the research interface between engineers, biological scientists, mathematicians and product manufacturing specialists. Perhaps a more encompassing description of cell engineering would therefore be the investigation manipulation,and enhancement of the biological processes that underpin cellular performance. This session intends to promote discussion of current leading edge research in this diverse area.

Session IV: Post-translational modifications/product integrity

9:00 -13:00
Chair: Ana Maria Moro Instituto Butantan Sao Paolo Brazil
Co-chair: Mike Butler University of Manitoba Winnipeg Canada

Many proteins depend on complex post-translational modifications (PTM) relating structure to appropriate functionality. PTM has influence on biological activity, half-life of the protein, its immunogenicity and stability. The choice of host cells for expression of recombinant therapeutic proteins is of utmost importance. Nowadays a lot of research is carried out trying to humanize other expression systems than mammalian cells, still considered the biological system of choice. Glycosylation is often very accurate and precise causing serious impact on product consistency. As many natural proteins present molecular heterogeneity and glycan isoforms, it can be a problem to understand the acceptable biological range. Other frequent PTM include amination, phosphorylation, carboxylation, hydroxylation, sulfation, folding, and pegylation. The regulatory authorities are raising the standards for demonstrating product consistency thus making process development and in-process control of great impact at industrial level. Endeavors for the development of sophisticated analytical tools have demonstrated the feasibility of ensuring consistent quality of products, synthesized as expected and not degraded by impurities or additives. To understand naturally occurring PTM, build biological systems capable of accomplishing PTM at acceptable levels, design and operate large-scale processes, and develop analytical tools to control PTM and protein integrity depend on multidisciplinary efforts with many interfaces. This session will present and discuss examples of PTM and product integrity both at development and industrial levels.
