Abstract

In most cases, the successful application of gene therapy requires the development of vectors that can provide regulated control of therapeutic gene expression. We have reconstituted the Tet-On (tetracycline-regulated transgene expression) two-component system in a single lentiviral vector with insertion of a chicken chromatin insulator (cHS4) element between the two expression cassettes. Optimization of this vector included an improved reverse tetracycline-dependent trans-activator (rtTA) sequence developed through HIV viral evolution, and an rtTA-dependent, Tet-responsive element containing modifications of the tetO sequence (TRE-tight1) to improve leaky basal transcription. Transduction of HeLa cells with these lentiviral vectors resulted in a high level of rtTA expression in the presence of doxycycline. In neuronal cells, rtTA expression driven by a neuron-specific enolase (NSE) promoter was more efficient than gene expression from a murine cytomegalovirus promoter. Transgene expression from the NSE promoter also provided tightly regulated gene expression in neurons in vivo.

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.
