Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

6.1K
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...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

The Bone Matrix01:18

The Bone Matrix

5.3K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

Glucose Homeostasis: Regulation of Blood Glucose01:02

Glucose Homeostasis: Regulation of Blood Glucose

3.6K
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...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose 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.
Insulin and C-peptide are...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

5.7K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Area of Science:

  • Endocrinology
  • Metabolism
  • Bone Biology

Background:

  • Bone is increasingly recognized for its endocrine functions beyond mineral metabolism, influencing glucose and energy regulation.
  • Recent research reveals a bidirectional communication (cross-talk) between bone cells and glucose homeostasis.
  • Skeletal fragility in diabetes is linked to metabolic dysregulation, including hyperglycemia and advanced glycation end products.

Purpose of the Study:

  • To review the intricate relationship between glucose metabolism and bone health in humans.
  • To synthesize recent evidence on how diabetes impacts bone and vice versa.
  • To explore the effects of antidiabetic and anti-osteoporosis medications on bone and glucose metabolism, respectively.

Main Methods:

  • Review of in vitro and murine studies on osteoblast/osteocyte-derived molecules and glucose metabolism.
  • Analysis of human studies investigating the skeletal consequences of type 1 and type 2 diabetes.
  • Examination of clinical data on the skeletal effects of antidiabetic drugs and the metabolic effects of anti-osteoporosis medications.

Main Results:

  • Diabetes-associated metabolic abnormalities (e.g., increased adipose tissue, hyperglycemia, CKD) contribute to skeletal fragility.
  • Advanced glycation end products and altered calcium-PTH-vitamin D metabolism are key mechanisms linking diabetes and bone disease.
  • Evidence suggests reciprocal influences between glucose-lowering and bone-protective therapies.

Conclusions:

  • The interplay between glucose and bone metabolism is critical for overall health, particularly in diabetic individuals.
  • Understanding these mechanisms is essential for managing skeletal complications in diabetes.
  • Further research is needed to reconcile discrepancies between basic and clinical findings regarding drug effects.
