Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

2.8K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...

Cell Specific Gene Expression

16.7K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Hormones Regulating Blood Glucose

7.5K
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...

Glucose Homeostasis: Regulation of Blood Glucose

4.7K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Area of Science:

  • Cardiovascular Biology
  • Endothelial Cell Biology
  • Diabetes Mellitus Research

Background:

  • Vascular complications are a major cause of morbidity and mortality in diabetes mellitus.
  • Hyperglycemia-induced endothelial dysfunction and impaired neovascularization are primary drivers of these complications.
  • Endothelial progenitor cells (EPCs) are vital for vascular repair and neovascularization.

Purpose of the Study:

  • To review the detrimental effects of high glucose on endothelial progenitor cells (EPCs).
  • To explore the mechanisms underlying high glucose-induced EPC dysfunction.
  • To discuss potential therapeutic agents for mitigating EPC dysfunction in diabetes.

Main Methods:

  • Review of existing literature on high glucose effects on EPCs.
  • Analysis of EPC function in high glucose conditions (in vitro and in vivo).
  • Examination of reactive oxygen species (ROS) role in EPC deficit.

Main Results:

  • High glucose significantly reduces EPC colony-forming units and impairs differentiation, proliferation, adhesion, migration, tubulization, secretion, mobilization, and homing.
  • Enhanced senescence of EPCs is observed under high glucose conditions.
  • Increased mitochondrial reactive oxygen species production is a key factor in high glucose-induced EPC dysfunction.

Conclusions:

  • Hyperglycemia-induced EPC dysfunction is a critical, yet under-recognized, contributor to diabetic vascular complications.
  • Future research should focus on the hemodynamic environment and aging factors affecting EPCs to develop novel treatments.
  • Targeting EPC dysfunction presents a promising therapeutic avenue for managing diabetic vascular disease.
