Abstract

A constructed human LINE-1 (L1Hs) element containing intact 5' and 3' untranslatable regions and an in-frame fusion between the L1Hs open reading frame 1 and the bacterial lacZ gene (p1LZ) was found to promote the expression of beta-galactosidase in a variety of transiently transfected cell types in tissue culture. Full-length RNA was detected in the transfected cells. Most of the RNA transcripts initiated at or near the beginning of the L1Hs segment. Sequences within the L1Hs segment of p1LZ were sufficient for expression of the reporter gene; however, modulation of the transcriptional regulatory region by upstream sequences was not ruled out. Deletion analysis revealed that the sequences most critical for transcription were located within the first 100 bp of L1Hs. Other sequences within the first 668 bp of L1Hs also contributed to overall expression. Expression of p1LZ was high in human teratocarcinoma cells and low in all other cell types. This pattern of cell-type-specific expression matches the known pattern of endogenous L1Hs transcription in cultured cells.

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.
