In streptozocin-induced diabetes of the rat with normal fasting insulin levels and marked hyperglycemia, the number of cytochalasin B-binding sites and of GLUT4 proteins diminishes in the PM whereas the GLUT1 proteins increase to a new ratio of about 1.5:1 GLUT4:GLUT1.
The results strongly suggest that green and black tea suppress high-fat diet-evoked hyperglycemia and insulin resistance by retaining the level of GLUT4 and increasing the level of GLUT4 on the plasma membrane in muscle.
Gene expression studies were performed for muscle (GLUT4) and liver tissues (IL6 and PAI1).There was a remarkable decrease in hyperglycemia within two weeks of injection by MetASCs as compared to metformin and ASCs alone.
Ameliorated TNF-α-induced inflammation and insulin resistance in adipocytes via activation of insulin signaling and enhanced GLUT4 translocation suggesting a reduced hyperglycemia associated with the metabolic syndrome.
[6]-Gingerol, from Zingiber officinale, potentiates GLP-1 mediated glucose-stimulated insulin secretion pathway in pancreatic β-cells and increases RAB8/RAB10-regulated membrane presentation of GLUT4 transporters in skeletal muscle to improve hyperglycemia in Lepr<sup>db/db</sup> type 2 diabetic mice.
In conclusion, these data provide insight that baicalin is a powerful and promising agent for the treament of hyperglycemia via AKT/AS160/GLUT4 and P38MAPK/PGC1α/GLUT4 pathway.
Piperine in pepper prevents hyperglycemia by GLUT4 translocation through CaMKKβ/AMPK signaling via TRPV1-dependent increase in the intracellular Ca<sup>2+</sup> level and ROS generation.
Liquorice flavonoid oil suppresses hyperglycaemia accompanied by skeletal muscle myocellular GLUT4 recruitment to the plasma membrane in KK-A<sup>y</sup> mice.
The role of aqueous-extract of garlic (AEG) and a purified NO-generating protein from garlic (NGPG) was investigated to control hyperglycemia by hepatic insulin synthesis through NGPG induced synthesis of NO via glucose-activated NO-synthase and glucose transporter-4 (Glut-4) in the hepatocytes.
The MSG administration induced hyperglycemia associated with a decrease in the skeletal muscle glucose transporter 4 (GLUT4) levels and accompanied by deregulation in proteins, G-6Pase, and tyrosine aminotransferase, involved in hepatic glucose metabolism of male and female rats.
Collectively, these data indicate that PNS reduces hyperglycemia and insulin resistance through up-regulating GLUT4 expression and the IRS1-PI3K-AKT signaling pathway.
These results suggest that green tea can ameliorate hyperglycemia in diabetic rodents by stimulating GLUT4-mediated glucose uptake in skeletal muscle, and that EGCG is one of the effective compounds that mediate this effect.
Thus, the effects of IOE to ameliorate hyperglycemia and adiposity may be mediated through FGF21 activating insulin signaling and increasing the expression of GLUT4 and pro-thermogenic factors.
Here we briefly discussed that wogonin increases Glut4 trafficking to plasma membrane which allows increased entry of glucose and thus alleviates hyperglycemia.
Animal studies revealed that VK supplementation dose-dependently upregulated plasma cGas6; stimulated the protein expression of cGas6, PI3K, pAKT, and GLUT4 in skeletal muscle; and reduced hyperglycemia in HFD-fed T2D mice.
