Glucose transporters (GLUT and SGLT): expanded families of sugar transport proteins

Open access
Wood, I. Stuart, Trayhurn, Paul·2003·British Journal of Nutrition

Abstract

The number of known glucose transporters has expanded considerably over the past 2 years. At least three, and up to six, Na+-dependent glucose transporters (SGLT1–SGLT6; gene name SLC5A) have been identified. Similarly, thirteen members of the family of facilitative sugar transporters (GLUT1–GLUT12 and HMIT; gene name SLC2A) are now recognised. These various transporters exhibit different substrate specificities, kinetic properties and tissue expression profiles. The number of distinct gene products, together with the presence of several different transporters in certain tissues and cells (for example, GLUT1, GLUT4, GLUT5, GLUT8, GLUT12 and HMIT in white adipose tissue), indicates that glucose delivery into cells is a process of considerable complexity.

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

  • GLUT-1 is the main expressed GLUT in red blood cell membrane and is not insulin dependent.

    “It could be explained by the fact that GLUT-1 is the main expressed GLUT in red blood cell (RBC) membrane which is not insulin dependent [22,110]; thus, insulin resistance would not affect FDG uptake in RBCs.”

    From Effect of blood glucose level on standardized uptake value (SUV) in 18F-FDG PET-scan: a systematic review and meta-analysis of 20,807 individual SUV measurements (2019) · cites this paper as [22]

    The Class I facilitative transporters section says GLUT1 is expressed particularly in erythrocytes, while the Perspective calls GLUT1 a constitutive transporter and distinguishes it from insulin-responsive GLUT4. The paper does not establish that GLUT1 is the main GLUT in the red-blood-cell membrane. (LLM, conf=0.82)

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.
