Mi2β-mediated silencing of the fetal γ-globin gene in adult erythroid cells
Open accessAbstract
Key Points: Mi2β exerts a major part of its silencing effect on embryonic and fetal globin genes by positively regulating the BCL11A and KLF1 genes. Partial depletion of Mi2β induces increased γ-globin gene expression in primary human erythroid cells without impairing differentiation.

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.
