Subsequent studies using cancer cells with stable knockdown or overexpression of PGRMC1 challenged the conclusion of an association because neither condition changed [3H]DTG binding.
“Subsequent studies using cancer cells having a stable knockdown or overexpression of PGRMC1 challenged these conclusions since neither condition resulted in a change in binding of the σ2R radioligand, [3H]DTG17,18.”

Later studies by two independent groups found that S2R binding activity was not altered irrespective of the level of PGRMC1 expressed, and full activity persisted even in the absence of PGRMC1.
“In later studies by two independent groups, however, in which PGRMC1 levels were genetically manipulated through overexpression or depletion, S2R binding activity was not altered irrespective of the level of PGRMC1 expressed, as assessed using the canonical S2R ligand tritiated di-o-tolylguanidine binding in the presence of saturating (+)-pentazocine, in a human epithelial cell line or a mouse mot”

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.
