Abstract

Background:

Chlorogenic Acid (CA) has diverse, recognized health effects.

Objective:

This study aimed to explore the effects of CA on fat reduction and the underlying mechanism of these effects.

Materials And Methods:

First, we established a Monosodium Glutamate (MSG)-induced obesity mouse model and subjected the mice to 4 weeks of CA gavage. Then, we established an oleic acidinduced model of human fatty liver in HepG2 cells, and administered a CA intervention to the cells for 48 h. Finally, we used Oil red O staining, biochemical detection kits, RT-PCR and Western blot analysis to evaluate the effects of CA on fat reduction and on related pathways.

Results:

The CA treatment could reduce fat accumulation in the liver and reduce blood lipid levels. In addition, CA decreased the mRNA and protein levels of peroxisome proliferator-activated receptor gamma, coactivator 1 α (PGC-1α) and Uncoupling Protein 1 (UCP1) in the MSG-induced obesity mouse model and the oleic acid-induced HepG2 cells.

Conclusion:

Based on the above results, we deduced that CA could reduce body weight and fat deposition in vitro and in vivo and that the mechanism may be related to the PGC-1α/UCP-1 pathway. CA can be developed as a drug to lower blood lipids and to treat obesity.

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Oral Hypoglycemic Agents: Biguanides and Glitazones

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Glucagon-like Receptor Agonists

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Indirect-Acting Cholinergic Agonists: Mechanism of Action

Indirect-Acting Cholinergic Agonists: Mechanism of Action

Indirect-acting cholinergic agonists work by interacting with an enzyme called acetylcholinesterase (AChE) in the synaptic cleft. They can be reversible or irreversible inhibitors and have different effects on the enzyme.
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...

Regulation of Metabolism

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
