Summary
Galectin-1, a protein linked to obesity and type 2 diabetes, increases in these conditions. Research highlights its role in metabolic pathways and diabetes complications, suggesting clinical potential.
Area of Science:
- Biochemistry
- Metabolic Research
- Endocrinology
Background:
- Galectin-1 is a conserved carbohydrate-binding protein vital for tissue homeostasis.
- Elevated galectin-1 levels are observed in obesity and insulin resistance in human and animal models.
- Increased galectin-1 expression in adipose tissue is consistently identified in obesity and insulin resistance.
Purpose of the Study:
- To review the current understanding of galectin-1's role in obesity and type 2 diabetes.
- To explore the clinical potential of galectin-1 as a biomarker or therapeutic target.
- To summarize evidence linking galectin-1 to metabolic pathways and diabetes complications.
Main Methods:
- Review of existing literature, including proteomic studies and large population-based cohorts.
- Analysis of studies investigating galectin-1 expression in obesity, insulin resistance, and type 2 diabetes.
- Examination of research on galectin-1's association with metabolic pathways, inflammation, and diabetes complications.
Main Results:
- Galectin-1 levels are elevated in circulation and adipose tissue in obesity.
- Associations found between circulating galectin-1 and insulin resistance markers, and incident type 2 diabetes.
- Galectin-1 is implicated in glucose/lipid metabolism, insulin signaling, inflammation, and diabetic complications like kidney disease and retinopathy.
Conclusions:
- Galectin-1 plays a significant role in the pathophysiology of obesity and type 2 diabetes.
- Its association with metabolic dysregulation and diabetic complications suggests potential clinical utility.
- Further research into galectin-1's therapeutic and diagnostic potential in metabolic diseases is warranted.

2.6K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

585
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...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

4.0K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
