Abstract

The uncoupling protein (UCP) of mammalian brown fat is a specialized and unique component responsible for energy dissipation as heat. Translation and immunoprecipitation from sucrose-fractionated mRNA indicated that the mRNA of UCP sedimented at 14-16 S. A recombinant cDNA library prepared from mRNA of thermoactive brown fat enriched for UCP mRNA has been constructed and cloned in Escherichia coli. Recombinant plasmids were screened by differential colony hybridization to a cDNA probe complementary to poly(A)+ RNA isolated from thermogenic or from weakly thermogenic brown fat. Several differentially hybridizing plasmids were shown to contain UCP cDNA sequences by their ability to select a mRNA coding for an in vitro translation product that was immunoprecipitable with antibodies against UCP. Blot hybridization of brown fat mRNA to a 32P-labeled UCP cDNA probe revealed two major species of mRNA (15S and 18S). As compared to non-thermogenic tissue, a strikingly increased hybridization to the probe was observed with brown fat mRNA from thermoactive tissue. Moreover, hybridization was observed with RNA of brown adipose tissue from rat, hamster, or mouse but not with RNA from rat or mouse liver.

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

  • UCP1 hinders the establishment of, or dissipates, a proton gradient of sufficient magnitude to sustain the synthetic activity of the mitochondrial ATPase, thus driving continuous accelerated electron transport.

    “UCP1 hinders the establishment of, or dissipates, a proton gradient of sufficient magnitude to sustain the synthetic activity of the mitochondrial ATPase (150, 153-155), thus driving continuous accelerated electron transport.”
  • In brown adipose tissue, electron transport is greatly accelerated due to tissue-specific expression of the mitochondrial UCP1.

    “In this tissue, electron transport is greatly accelerated due to tissue-specific expression of the mitochondrial UCP1.”

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.
