Abstract

A 2432-bp cDNA for mouse FAD-linked glycerol-3-phosphate dehydrogenase, a nuclear-encoded enzyme associated with the inner mitochondrial membrane, was isolated from a Lambda ZAP phage library generated from brown adipocyte mRNA. The amino acid sequence was 95 and 93% homologous to the rat and human enzymes. PvuII and SacI polymorphisms between Mus spretus and C57BL/6J were used to map the mouse FAD-linked glycerol-3-phosphate dehydrogenase gene (Gdm1) to chromosome 2, 33 cM from the centromere. Northern blot analysis showed that brown adipose tissue predominantly expressed a 6.5-kb mRNA with lower expression of 4.5- and 2.4-kb forms, whereas brain and pancreatic islets almost exclusively expressed a 6.5-kb transcript, muscle expressed a 4.5-kb transcript, and testis expressed a 2.4-kb RNA form. Analysis of poly(A)+ RNA from brown adipose tissue suggested that all RNA forms are polyadenylated. Among the tissues examined, FAD-linked glycerol-3-phosphate dehydrogenase protein levels and enzyme activity were highest in brown adipose tissue, and a consistent correlation between protein levels and enzyme activity in all tissues was observed. RNA levels corresponded to protein levels in all tissues except testis, where high levels of 2.4-kb mRNA and relatively low protein were expressed. Exposing mice to cold temperatures induced the 6.5-kb mRNA and enzyme activity only in brown adipose tissue, suggesting a role for thermogenesis in this tissue. Although the molecular basis for the formation of the 6.5- and 4.5-kb mRNA's is not known, data suggest that the regulation of FAD-linked glycerol-3-phosphate dehydrogenase is complex and tissue-specific.

  • The glycerol 3-phosphate shuttle is not considered the major route of NADH shuttling in most mammalian cells but is particularly active in brown adipose tissue and may be implicated in thermoregulation.

    “The glycerol 3-phosphate shuttle is not considered the major route of NADH shuttling in most mammalian cells but has been shown to be particularly active in brown adipose tissue and may be implicated in thermoregulation (105, 106, 107).”

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.
