A One-Step Gene Amplification System for Use in Cultured Mammalian Cells and Transgenic Animals
Abstract
Gene amplification is widely used for the production of pharmaceuticals and therapeutics in situations where a mammalian system is essential to synthesise a fully active product. Current gene amplification systems require multiple rounds of selection, often with high concentrations of toxic chemicals, to achieve the highest levels of gene amplification. The use of these systems has not been demonstrated in specialised mammalian cells, such as embryonic-stem cells, which can be used to generate transgenic animals. Thus, it has not yet proved possible to produce transgenic animals containing amplified copies of a gene of interest, with the potential to synthesise large amounts of a valuable gene product. We have developed a new amplification system, based around vectors encoding a partially disabled hypoxanthine phosphoribosyltransferase (HPRT) minigene, which can achieve greater than 1000-fold amplification of HPRT and the human growth hormone gene in a single step in Chinese hamster-lung cells. The amplification system also works in mouse embryonic-stem cells and we have used it to produce mice which express 30-fold higher levels of human protein C in milk than obtained with conventional transgenesis using the same protein C construct. This system should also be applicable to large animal transgenics produced by nuclear transfer from cultured cell lines.

Other selection systems developed more recently include the OSCAR system, which uses minigene vectors encoding hypoxanthine phosphoribosyltransferase (HPRT), essential for purine synthesis.
“Other selection systems have been developed more recently, such as the OSCAR™ system from the University of Edinburgh, that uses minigene vectors encoding the hypoxanthine phosphoribosyltransferase (HPRT), essential for purine synthesis (Melton et al., 2001;Costa et al., 2012).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
