This method was applied to elucidate the putative interdependencies of the cell cycle and recombinant protein expression in the human producer cell line HEK293s using Lipofectamine 2000 and the reporter plasmid pcDNA3.3 enhanced green fluorescent protein, destabilized using PEST sequence. A population-resolved modeling approach was applied to quantitatively assess putative variations of cell cycle dependent expression rates based on the obtained experimental data. We could not confirm results published earlier by other groups, based on nonphysiological synchronization attempts, reporting transfection efficiency being strongly dependent on the cell cycle phase at transfection time point. On the other hand, it is demonstrated that transfection and protein expression distort the progression of the cell cycle.||URI:||http://hdl.handle.net/11420/3224||ISSN:||1618-2863||Institute:||Bioprozess- und Biosystemtechnik V-1||Type:||(wissenschaftlicher) Artikel||Funded by:||Funding by the Deutsche Forschungsgemeinschaft (DFG; research project “Neue Ansätze zur populationsbasierten kinetischen Untersuchung und Modellierung von Hochzelldichte‐Zellkulturen,” Grant Number: ZE 542/9‐1) as well as partial funding by German Federal Ministry of Education and Research (BMBF, Grant Number 031A128).|
