Abstract

In a previous study we showed that genomic constructs were expressed more efficiently in transgenic mice than constructs that were identical except for the lack of introns. Using the mouse metallothionein promoter-rat growth hormone gene construct as a model, we show that the first intron of the rat growth hormone gene is essential for high-level expression, whereas the other three introns are less effective. Several heterologous introns placed 3' of the coding region of an intronless rat growth hormone gene are also ineffective. However, insertion of some heterologous introns between the metallothionein promoter and the growth hormone gene improves expression. To determine whether addition of heterologous introns would provide a general strategy for improving expression, we have tested them in conjunction with other intronless genes and with different promoters.

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.
