The effects of glucagon-like peptide-1 (GLP-1) on adipose cells in type-2 diabetes mellitus (T2DM) / Noor Mazuin Abu Bakar
Glucagon-like peptide 1 (GLP-1) is a member of incretin group hormone. It is produced by the L-cells of the intestines, serving as a postprandial communication messenger between the gut and other organs. It has numerous physiological roles, such as improving glucose-stimulated insulin secretion, enh...

Glucagon-like peptide 1 (GLP-1) is a member of incretin group hormone. It is produced by the L-cells of the intestines, serving as a postprandial communication messenger between the gut and other organs. It has numerous physiological roles, such as improving glucose-stimulated insulin secretion, enhancement of pancreatic β-cell proliferation, inhibition of glucagon release and promotion of satiety. GLP-1 has attracted an immense interest in research due to its antidiabetic effects for the treatment of patients with Type-2 Diabetes Mellitus (T2DM). However, the direct effects of GLP-1 on adipocytes are poorly characterized. In this study, an in vitro model of a dexamethasone-induced T2DM 3T3-L1 mouse adipose cells was chosen to demonstrate the metabolic effects of GLP-1 treatment and its actions on the cell’s gene expression.
