Abstract

Reactivating the fetal globin gene: Mutation of adult-type globin genes causes sickle cell disease and thalassemia. Although treating these hemoglobinopathies with gene therapy is possible, there is a pressing need for pharmacologic approaches to treat general patient populations. One promising approach is to reactivate repressed expression of fetal-type hemoglobin (HbF) in adult erythroid cells. Masuda et al. reveal a molecular mechanism governing HbF repression as mediated by the LRF/ZBTB7A transcription factor. The study may encourage the development of new HbF reactivation therapies for hemoglobinopathies. Science , this issue p. 285

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

  • Inactivation of ZBTB7A in HUDEP-2 cells led to approximately 50% HbF, and BCL11A plus ZBTB7A knockout caused more than 90% HbF.

    “Its inactivation in HUDEP-2 cells led to ;50% HbF; BCL11A plus ZBTB7A knockout caused .90% HbF. 25”

    From Fetal hemoglobin in sickle cell anemia (2020) · cites this paper as [25]

    The HUDEP-2 results report HbF above 60% in all three ZBTB7A-knockout clones, not approximately 50%. The double-knockout results report HbF at 91–94% of total hemoglobin, supporting the second figure. (LLM, conf=0.91)

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.
