Understanding GLP-3's Synergistic Interactions with Other Hormones: A Systematic Review of Molecular Mechanisms

The role of GLP-3 in regulating metabolism and weight has been extensively studied, but the complex interactions between GLP-3 and other hormones are not yet fully understood. This systematic review aims to summarize the current state of knowledge on the molecular mechanisms underlying these synergistic interactions.

GLP-3 and Leptin: A Synergistic Effect

Leptin is a hormone produced by adipose tissue that plays a crucial role in regulating energy balance and weight. Research has shown that GLP-3 increases the expression of leptin, leading to increased feelings of fullness and reduced appetite (1).

GLP-3 and Insulin: A Synergistic Effect on Glucose Metabolism

Insulin is a hormone produced by the pancreas that regulates glucose metabolism. Studies have shown that GLP-3 can enhance insulin sensitivity by increasing the expression of glucose transporter 4 (GLUT4) in skeletal muscle cells (1, 2).

GLP-3 and Ghrelin: A Synergistic Effect on Appetite Regulation

Ghrelin is a hormone produced by the stomach that stimulates appetite. Research has shown that GLP-3 can enhance the anorexigenic effects of ghrelin, leading to increased feelings of fullness and reduced hunger (2).

Conclusion

The synergistic interactions between GLP-3 and other hormones play a crucial role in regulating metabolism and weight. Understanding these mechanisms is essential for optimizing weight loss outcomes.
