Human Endogenous Metabolite
|
In Arabidopsis cell cultures, Abscisic acid ((S)-(+)-Abscisic acid; 10 μM) simultaneously induces rapid alkalinization of the medium and plasma membrane depolarization.
Abscisic acid (10 μM) increases Ca
2+
in cytosol of Arabidopsis cell suspension. Abscisic acid does not inhibit proton pumping directly but through an increase in cytosolic Ca
2+
.
Lanthionine synthetase C-like 2 (LANCL2) is the natural receptor for Abscisic acid. Abscisic acid, both at the organism levels and in specific muscle cells ex vivo, increases both glucose and fatty acid metabolism in the mitochondria, increases glycogen synthesis, activates PI3K independently of insulin and promotes GLUT4 translocation to the cell membrane.
Abscisic acid (orally; 0.125?μg/kg/day; for 12 weeks) improves glycemic control.
Abscisic acid (orally; 0.125?μg/kg/day; for 12 weeks) results in significantly lower levels of TNF, MCP-1 and IL-6 in the DIO model. Abscisic acid increases metabolic activity in skeletal muscle.
| Animal Model: | Diet-induced obesity (DIO) mice at 4 weeks of age |
| Dosage: | 0.125?μg/kg |
| Administration: | Orally; daily; for 12 weeks |
| Result: | Improved glycemic control in a diet-induced model of obesity |
