Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

5.2K
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...

Diabetes Mellitus: Overview and Type I Subtype

5.7K
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...

Pathophysiology of Diabetes

4.0K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

14.6K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

19.3K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

5.2K
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...

Area of Science:

  • Metabolic disorders
  • Cellular bioenergetics

Background:

  • Insulin resistance is a key predictor of type 2 diabetes (T2D).
  • It involves defects in glucose uptake, hepatic glucose production, lipolysis, and insulin secretion.
  • Mitochondrial dysfunction is frequently observed in individuals with insulin resistance and T2D.

Purpose of the Study:

  • To examine the evidence linking mitochondrial dysfunction and insulin resistance.
  • To review the role of mitochondria in T2D pathogenesis.
  • To explore therapeutic strategies targeting mitochondria for T2D.

Main Methods:

  • Review of existing scientific literature.
  • Analysis of studies on individuals with insulin resistance and T2D.
  • Examination of data on mitochondrial function (bioenergetics, biogenesis, dynamics).

Main Results:

  • Insulin resistance is associated with widespread mitochondrial defects.
  • The precise causal relationship between mitochondrial dysfunction and insulin resistance is still under investigation.
  • Mitochondrial dysfunction may be either a primary defect or secondary to metabolic derangements.

Conclusions:

  • Mitochondrial dysfunction is closely associated with insulin resistance and T2D.
  • Targeting mitochondrial function presents a potential therapeutic avenue for T2D.
  • Further research is needed to elucidate the primary role of mitochondria in T2D development.
