The facilitative glucose transporter GLUT3: 20 years of distinction.
Glucose metabolism is vital to most mammalian cells, and the passage of glucose across cell membranes is facilitated by a family of integral membrane transporter proteins, the GLUTs. There are currently 14 members of the SLC2 family of GLUTs, several of which have been the focus of this series of reviews. The subject of the present review is GLUT3, which, as implied by its name, was the third g...
متن کاملGlucose transporter GLUT3: ontogeny, targeting, and role in the mouse blastocyst.
The first differentiative event in mammalian development is segregation of the inner cell mass and trophectoderm (TE) lineages. The epithelial TE cells pump fluid into the spherical blastocyst to form the blastocyst cavity. This activity is fuelled by glucose supplied through facilitative glucose transporters. However, the reported kinetic characteristics of blastocyst glucose transport are inc...
متن کاملThe GLUT3 glucose transporter isoform is differentially expressed within human placental cell types.
The cellular localization of GLUT3 messenger ribonucleic acid (mRNA) and protein was examined in human term placenta using a combination of methodologies. In situ hybridization indicated that GLUT3 mRNA was present in the trophoblast cell layer and in vascular endothelium with a heterogeneous distribution pattern. GLUT3 protein migrating at an apparent molecular mass of 49 kDa was detected by i...
متن کاملThe Drosophila copper transporter Ctr1C functions in male fertility.
Living organisms have evolved intricate systems to harvest trace elements from the environment, to control their intracellular levels, and to ensure adequate delivery to the various organs and cellular compartments. Copper is one of these trace elements. It is at the same time essential for life but also highly toxic, not least because it facilitates the generation of reactive oxygen species. I...
متن کاملUnique mechanism of GLUT3 glucose transporter regulation by prolonged energy demand: increased protein half-life.
L6 muscle cells survive long-term (18 h) disruption of oxidative phosphorylation by the mitochondrial uncoupler 2,4-dinitrophenol (DNP) because, in response to this metabolic stress, they increase their rate of glucose transport. This response is associated with an elevation of the protein content of glucose transporter isoforms GLUT3 and GLUT1, but not GLUT4. Previously we have reported that t...
