Summary
Insulin signaling in bone marrow promotes fat cell formation and senescence, contributing to metabolic bone diseases. Understanding this pathway
Area of Science:
- Endocrinology
- Metabolic Bone Diseases
- Cellular Senescence
Background:
- Bone is an insulin-responsive organ crucial for whole-body energy metabolism.
- Obesity and type 2 diabetes are linked to increased fracture risk and bone marrow adiposity.
- Peripheral insulin signaling is impaired in obesity, leading to insulin resistance.
Purpose of the Study:
- To review the role of insulin signaling in bone marrow adipocyte formation and function.
- To discuss insulin signaling's contribution to cellular senescence in metabolic bone diseases.
- To highlight differences between bone marrow and peripheral fat metabolism for therapeutic insights.
Main Methods:
- Review of current scientific literature on insulin signaling in bone marrow.
- Analysis of the impact of insulin signaling on bone marrow adipocytes and stem cells.
- Comparison of bone marrow and peripheral adipose tissue metabolism.
Main Results:
- Insulin signaling is maintained in the bone marrow microenvironment during obesity.
- This leads to a hypermetabolic state in bone marrow stromal stem cells.
- Accelerated senescence and increased bone marrow adipocytes are observed in obesity.
Conclusions:
- Insulin signaling in bone marrow plays a key role in adipocyte accumulation and senescence.
- Dysregulated insulin signaling contributes to metabolic bone diseases.
- Targeting bone marrow-specific insulin signaling pathways may offer novel therapeutic strategies.

01:28Insulin: The Receptor and Signaling Pathways
2.5K
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...

6.2K
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...

01:22PI3K/mTOR/AKT Signaling Pathway
5.2K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
2.0K
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.

01:05Insulin Secretory Vesicles
6.3K
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...

01:45Endocrine Signaling
67.5K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
