Summary
Visfatin, an adipocytokine, exhibits insulin-mimetic activity and is linked to obesity. This review details its metabolic effects in humans, focusing on obesity-related pathways.
Area of Science:
- Metabolic research
- Adipokine signaling
- Obesity studies
Background:
- Visfatin, a product of the PBEF gene, is an adipocytokine with significant insulin-mimetic properties.
- Previous research has established a correlation between visfatin and obesity.
- Emerging evidence highlights visfatin's intracellular roles due to its homology with nicotinamide phosphoribosyltransferase (NAMPT).
Purpose of the Study:
- To review the documented metabolic effects of visfatin in humans.
- To emphasize the specific pathways through which visfatin influences obesity.
Main Methods:
- Literature review of studies on visfatin and human metabolism.
- Analysis of research focusing on visfatin's role in obesity-related pathways.
Main Results:
- Visfatin demonstrates potent insulin-mimetic activity.
- Visfatin is associated with obesity and plays a role in metabolic regulation.
- Intracellular functions of visfatin, related to NAMPT, are significant.
Conclusions:
- Visfatin is a key adipocytokine influencing human metabolism.
- Understanding visfatin's pathways is crucial for addressing obesity.
- Further research into visfatin's intracellular actions is warranted.

Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
Fats as Energy Storage Molecules
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis directly...

Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Cholesterol: Significance and Regulation
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
