Abstract

We have identified cDNAs clones for several cold-inducible mRNAs from the brown adipose tissue of mice. pCIN-1, a plasmid with a 900-base pair insert, encoded the mitochondrial uncoupling protein (UCP) as determined by the ability of the cDNA insert to select, by hybridization, an mRNA that could be translated into a 32,000-Da protein immunoprecipitable with anti-UCP antibodies. Nine tissues were analyzed; however, UCP cDNA hybridized to an mRNA species of 1.6 and 2.0 kilobase pairs only in brown adipose tissue. A maximum induction of 10-fold occurred within 6 h of exposure to cold (5 degrees C). A BamHI restriction fragment polymorphism detected by Southern blot analysis of genomic DNA in recombinant inbred mouse strains allowed us to map the UCP gene to Chromosome 8. The analysis of the UCP gene expression in diabetic (db) and obese (ob) mice maintained at 27 degrees C for 3 days followed by cold exposure for 4 h at 5 degrees C indicated that UCP mRNA levels in mutant mice were unaffected at 27 degrees C and only slightly reduced at 5 degrees C. Accordingly, the inability of diabetic and obese mice to thermoregulate is not associated with a lack of UCP mRNA induction.

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

  • UCP-1 is a transmembrane protein localized in the inner mitochondrial membrane that catalyzes proton transport across the mitochondrial membrane and thereby induces mitochondrial uncoupling.

    “UCP-1 is a transmembrane protein localized in the inner mitochondrial membrane catalyzing the transport of protons across the mitochondrial membrane and thereby inducing mitochondrial uncoupling [7].”
  • Strong evidence of mitochondrial uncoupling property is clear for UCP-1 but still heavily debated for other UCPs.

    “Importantly, although strong evidence of the mitochondrial uncoupling property is clear for UCP-1 [7,12], it is still heavily debated for the other UCPs [13,14,15].”
  • 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.”
  • 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.”

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.
