Abstract

Synthesis of the brown adipocyte-specific mitochondrial uncoupling protein thermogenin (UCP) is demonstrated here in brown adipocytes differentiated in culture from precursor cells. By immunoblotting, no UCP was detectable in untreated multilocular adipocytes. The synthesis of UCP was stimulated by norepinephrine at physiological concentrations and was observable already after 2 h. It was evident from immunoelectron microscopy that the newly synthesised protein was targeted to the mitochondrial inner membrane, demonstrating the functional competence of these 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.
