Feedback Loops01:01

Feedback Loops

64.1K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

6.5K
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: Pancreatic Islets and Insulin Secretion

2.2K
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...

Insulin Secretory Vesicles

6.4K
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...

Glucose Homeostasis: Regulation of Blood Glucose

3.9K
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...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

16.3K
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...

Area of Science:

  • Endocrinology
  • Metabolic Syndrome Research
  • Diabetes Pathophysiology

Background:

  • Androgen deficiency in men is correlated with metabolic syndrome and type 2 diabetes.
  • The mechanisms linking androgens to glucose homeostasis are not fully understood.
  • Previous research focused on androgen actions in peripheral insulin target tissues.

Purpose of the Study:

  • To investigate the role of androgens and their receptor in regulating insulin secretion.
  • To elucidate the direct impact of androgens on pancreatic beta cells.

Main Methods:

  • Utilized cell-based assays to examine insulin secretion.
  • Investigated the expression and function of the androgen receptor in beta cells.
  • Employed molecular and genetic techniques to study androgen signaling pathways.

Main Results:

  • Demonstrated that androgens directly influence insulin secretion from beta cells.
  • Identified the androgen receptor as a key mediator of this effect.
  • Showcased a novel mechanism by which androgens modulate glucose homeostasis.

Conclusions:

  • Androgens play a crucial, previously unrecognized role in regulating insulin secretion.
  • Targeting androgen signaling in beta cells may offer new therapeutic strategies for metabolic disorders.
  • This study expands our understanding of the intricate relationship between hormones and metabolic health.
