Cell Specific Gene Expression

Cell Specific Gene Expression

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...

Insulin Secretory Vesicles

Insulin Secretory Vesicles

Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Cells and Secretions of the Pancreas

Cells and Secretions of the Pancreas

The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

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 co-secreted in...

Insulin: The Receptor and Signaling Pathways

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 Agonists

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...

Summary

Kisspeptin (KISS1) and its receptor (GPR54) are present in pancreatic islets. KISS1 stimulates glucose-induced insulin secretion in human and mouse islets, suggesting a role in islet function regulation.

Background:

The kisspeptin (KISS1) and GPR54 system is crucial for reproductive function.
Its presence and role in the endocrine pancreas remain largely unexplored.

Purpose of the Study:

To investigate the expression of KISS1 and GPR54 in pancreatic islets.
To determine the impact of exogenous kisspeptin on insulin secretion from pancreatic islets.

Main Methods:

RT-PCR and immunohistochemistry were employed to detect KISS1 and GPR54.
Human and mouse islets, along with beta (MIN6) and alpha (alphaTC1) cell lines, were utilized.
Insulin secretion was measured using a perifusion system.

Main Results:

KISS1 and GPR54 mRNAs were detected in human and mouse islets and cell lines.
KISS1 and GPR54 proteins were co-localized in pancreatic islet beta and alpha cells.
Kisspeptin stimulated glucose-induced insulin secretion in human and mouse islets but inhibited it in MIN6 cells.

Conclusions:

The GPR54/KISS1 system is expressed in the endocrine pancreas.
This system influences beta cell secretory function.
It plays a significant role in the regulation of normal islet function.
