Insights

Insulin-like growth factor 1 (IGF-1) shows promise in treating severe insulin resistance by lowering blood glucose and insulin levels. Clinical trials suggest rhIGF-1 may be a viable option for managing severe insulin resistance symptoms.

Area of Science:

  • Endocrinology
  • Metabolic Disorders

Background:

  • Severe insulin resistance is a complex condition with limited treatment options.
  • Understanding molecular mechanisms has yielded few therapeutic advances.

Purpose of the Study:

  • To evaluate the efficacy of Insulin-like Growth Factor 1 (IGF-1) in managing severe insulin resistance.
  • To explore IGF-1's potential therapeutic role in improving glucose metabolism and insulin sensitivity.

Main Methods:

  • Review of existing literature on IGF-1's effects on glucose and insulin levels.
  • Analysis of small-scale clinical trials involving recombinant human IGF-1 (rhIGF-1) in patients with severe insulin resistance.

Main Results:

  • IGF-1 effectively lowers blood glucose and serum insulin levels in normal volunteers.
  • IGF-1 demonstrated improvement in insulin resistance in type 2 diabetes and severe insulin resistance cases.
  • Clinical trials indicated potential utility of rhIGF-1 in selected severe insulin resistance cases.

Conclusions:

  • IGF-1 offers a potential therapeutic strategy for severe insulin resistance.
  • The risk-benefit ratio favors rhIGF-1 use in specific severe insulin resistance cases for symptom amelioration.

Diabetes Mellitus: Overview and Type I Subtype01:22

Diabetes Mellitus: Overview and Type I Subtype

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.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
Glucagon-like Receptor Agonists01:24

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 the...
Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
