Abstract

We have tested the effect of the individual DNase I hypersensitive site (HS) regions of the globin locus control region (LCR) on the developmental expression pattern of the human gamma and beta genes in transgenic mice. The results show that HS3 is the most active site during the embryonic period. It is also the only site capable of high level expression of the gamma genes during fetal hematopoiesis, in a population of cells that are capable of expressing both the gamma and beta genes. Region HS4 shows the highest activity during the adult stage and expresses the gamma genes only at low levels during the embryonic period. HS2 drives equivalent levels of gamma or beta transgene expression throughout development. HS1 has a similar pattern to HS2, although the activity of HS1 is very low. From these results we conclude that the HS regions have distinct developmental specificities and suggest that in the complete LCR they interact with each other to form a larger complex which, in turn, interacts with the globin genes.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • HS1 has no intrinsic enhancer activity in embryonic, fetal, or adult erythropoiesis.

    “when tested individually, HS1 has no intrinsic enhancer activity in embryonic, fetal, or adult erythropoiesis;45”

    From Super-enhancers include classical enhancers and facilitators to fully activate gene expression (2023) · cites this paper as [45]

    The HS1 transgenic-line results (Fig. 3; page unavailable in our copy) report expression above the comparison lines in the embryonic yolk sac, fetal liver, and adult blood. The paper concludes that HS1 has very weak activity, not no activity; the Abstract likewise describes its activity as very low. (LLM, conf=0.95)

    Checked by a reasoning model — may be wrong.

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.
