Disease relevance of SLC2A4

 

Psychiatry related information on SLC2A4

  • Taken together, the results suggest that feeding behavior influences GLUT4 gene expression pattern through changes in sympathetic activity, especially during long-term starvation periods [6].
  • Based on the possible dependency of GLUT4 expression on volume, we hypothesize that the reduced GLUT4 expression in obesity and type 2 diabetes may partly be compensated for by physical activity [7].
 

High impact information on SLC2A4

 

Chemical compound and disease context of SLC2A4

 

Biological context of SLC2A4

 

Anatomical context of SLC2A4

  • In muscle and fat cells, insulin stimulates the delivery of the glucose transporter GLUT4 from an intracellular location to the cell surface, where it facilitates the reduction of plasma glucose levels [21].
  • Overexpression of GLUT4 in skeletal muscle enhances whole-body insulin action [22].
  • Perhaps consistent with a less efficient insulin signaling, a twofold reduction in GLUT4, glycogen synthase, and leptin mRNA expression was observed in omental adipose tissue [23].
  • Here, we report that an Eps15 homology (EH) domain-containing protein, EHD1, controls the normal perinuclear localization of GLUT4-containing membranes and is required for insulin-stimulated recycling of these membranes in cultured adipocytes [24].
  • GLUT4 trafficking between endosomes and trans-Golgi network was regulated via an acidic targeting motif in the carboxy terminus of GLUT4, because a mutant lacking this motif was retained in endosomes [25].
 

Associations of SLC2A4 with chemical compounds

  • This indicates that mitochondrial dysfunction decreases insulin-stimulated SLC2A4 translocation and glucose uptake [26].
  • Sequence analysis of the GLUT-4 gene revealed that one patient was heterozygous for a mutation in which isoleucine (ATC) was substituted for valine (GTC) at position 383 [1].
  • Insulin receptor number, activation of the insulin receptor tyrosine kinase in situ and after solubilization, and the total pool of glucose transporters (GLUT4) were unaffected, and glycogen synthase was activated by glucosamine pretreatment [27].
  • Reporter studies in H9C2 cardiomyotubes showed that HL in vitro, induced by high levels of arachidonic (AA) stearic, linoleic, and oleic acids (24 h, 200 mum) repressed transcription from the GLUT4 promoter; AA also repressed transcription from the PPARgamma1 and PPARgamma2 promoters [19].
  • The sequence of the protein-coding region of the GLUT4 gene and all intron-exon junctions was determined for a single diabetic Pima Indian and was identical to that of the cloned gene and cDNA [2].
 

Physical interactions of SLC2A4

  • These data demonstrate that exercise increases MEF2 and GEF DNA binding and imply that these transcription factors could be potential targets for modulating GLUT4 expression in human skeletal muscle [28].
  • Insulin and AICAR increased glucose transport and cell-surface GLUT4 content to a similar extent in control subjects [29].
  • Together these data demonstrated that MEF2 binding activity is necessary for regulation of the GLUT4 gene promoter in muscle and adipose tissue [30].
  • These findings strongly suggest that EHD2 interacts with GLUT4 in rat adipocytes and may play a key role in insulin-induced GLUT4 recruitment to the plasma membrane [31].
  • Heterologous expression of rab4 reduces glucose transport and GLUT4 abundance at the cell surface in oocytes [32].
 

Co-localisations of SLC2A4

 

Regulatory relationships of SLC2A4

  • Role of EHD1 and EHBP1 in perinuclear sorting and insulin-regulated GLUT4 recycling in 3T3-L1 adipocytes [24].
  • Activation of AMPK is an attractive strategy to enhance glucose transport through increased cell surface GLUT4 content in insulin-resistant skeletal muscle [29].
  • In contrast, insulin- and AICAR-stimulated responses on glucose transport and cell-surface GLUT4 content were impaired in subjects with type 2 diabetes [29].
  • We recently reported that the Krüppel-like zinc finger transcription factor KLF15 can induce adipocyte maturation and GLUT4 expression [34].
  • These data strongly suggest that the MEF2A-MEF2D heterodimer is selectively decreased in insulin-deficient diabetes and is responsible for hormonally regulated expression of the GLUT4 gene [35].
 

Other interactions of SLC2A4

  • Mechanistically, we show that nephrin allows the GLUT1- and GLUT4-rich vesicles to fuse with the membrane of this cell [36].
  • Insulin receptor substrate 1 mediates the stimulatory effect of insulin on GLUT4 translocation in transfected rat adipose cells [37].
  • Similarly, small interfering RNA-mediated depletion of endogenous EHD1 protein also markedly dispersed perinuclear GLUT4 in cultured adipocytes [24].
  • RBP4 was positively correlated with GLUT4 expression in adipose tissue, independent of any obesity-associated variable [38].
  • Moreover, EHD1 is shown to interact through its EH domain with the protein EHBP1, which is also required for insulin-stimulated GLUT4 movements and hexose transport [24].
