生物活性

Glucagon (1-29), bovine, human, porcine hydrochloride is a peptide hormone, produced by pancreatic α-cells. Glucagon hydrochloride stimulates gluconeogenesis[1]. Glucagon (1-29), bovine, human, porcine hydrochloride activates HNF4α and increases HNF4α phosphorylation[2][3].

体外研究
(In Vitro)

Upon binding to its receptor Gcgr, Glucagon activates cAMP-PKA signaling to stimulate hepatic glucose production (HGP) and cause hyperglycemia[1].
Glucagon stimulates both hepatic kisspeptin1 production and gluconeogenesis[1].
Glucagon (100 nM) represses CYP7A1 mRNA expression in human primary hepatocytes[3].
Glucagon (100 nM) increases phosphorylayion of HNF4α[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[3]

Cell Line: Human primary hepatocytes (H1211, HH1215)
Concentration: 100 nM
Incubation Time:
Result: Resulted in a marked increase in the amount of phosphorylated HNF4α.

体内研究
(In Vivo)

Low-dose (20 μg/kg) Glucagon increases glycemia and does not stimulate insulin secretion in ambient-fed mice. High-dose (1 mg/kg) Glucagon lowers glycemia compared with PBS control and stimulates insulin secretion in ambient-fed mice[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6J mice (12- to 24-week-old)[4]
Dosage: 20 μg/kg and 1 mg/kg
Administration: Administered by i.p. injection; 45 minutes
Result: Low-dose (20 μg/kg) increased glycemia and did not stimulate insulin secretion.
High-dose (1 mg/kg) lowered glycemia and stimulated insulin secretion.

Κ opioid receptor[1].

体内研究
(In Vivo)

Dynorphin A (1-13) exposure (33 μM) causes a significant loss in neuronal viability at 4 h with a visible destruction in neuronal morphology seen at 16 h. Exposure to dynorphin A (1-13) causes acute increases in [Ca2+]i in individual neurons similar to increases seen with acute NMDA treatment. Continuous exposure to dynorphin A (1-13) (100 μM) causes a significant loss of neurons over time[1].
