1Diabetes Research Group, Institute of Life Science 1, Swansea University, Swansea, UK.
Summary
Ghrelin, a hormone impacting metabolism, influences the hypothalamus, pancreas, and fat cells. Understanding its role in lipid retention could lead to new therapies for obesity and type 2 diabetes.
Area of Science:
- Endocrinology
- Metabolic Research
- Molecular Biology
Background:
- Ghrelin is a 28-amino acid hormone with diverse metabolic functions.
- Its influence extends to key metabolic regulators like the hypothalamus, pancreas, and adipocytes.
Purpose of the Study:
- To review the integrated pathways of ghrelin's metabolic effects.
- To explore molecules and pathways regulating ghrelin-mediated lipid retention.
- To identify potential therapeutic targets for metabolic dysfunction.
Main Methods:
- Literature review focusing on ghrelin signaling pathways.
- Analysis of studies investigating ghrelin's impact on cellular energy homeostasis.
- Examination of research on acyl-ghrelin's role in glucose and lipid metabolism.
Main Results:
- Ghrelin signaling significantly impacts hypothalamic, pancreatic, and adipocyte functions.
- Specific molecules and pathways involved in ghrelin-mediated lipid retention are being identified.
- Acyl-ghrelin plays a crucial role in regulating glucose and lipid homeostasis.
Conclusions:
- Understanding ghrelin's mechanisms offers insights into cellular energy balance.
- Targeting ghrelin pathways may provide novel strategies for treating obesity-related type 2 diabetes and metabolic disorders.

1.5K
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...

01:30Regulation of Food Intake
3.0K
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...

01:24Glucagon-like Receptor Agonists
1.1K
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...

5.3K
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...

01:15Hypoglycemia and Glucagon
1.1K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

01:16Hormones Regulating Blood Glucose
7.9K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
