|February 2, 2016
Summary
Melatonin supplementation significantly enhances bone tissue reactivity in aging rats. This effect is more pronounced in older animals, suggesting a potential role for melatonin in age-related bone health.
Area of Science:
- Biomedical Science
- Bone Physiology
- Endocrinology
Context:
- Bone tissue (BT) aging is associated with decreased mechanical properties.
- Melatonin (MT) is a hormone with known antioxidant and anti-inflammatory effects.
- Investigating MT's impact on BT's electrical properties provides novel insights into bone aging.
Purpose:
- To investigate the effect of melatonin supplementation on the reactive properties of bone tissue in aging male Wistar rats.
- To assess the age-dependent response of bone tissue reactivity to melatonin.
Summary:
- Male Wistar rats (3, 9, 12, and 16 months old) received daily melatonin (1 mg/kg) for 28 days.
- Bone tissue reactivity was measured by electrical polarization (reactance).
- Melatonin significantly increased bone mass and polarization properties, with a notable age-dependent increase in reactance, particularly in older rats (21.8% increase in 15-month-olds).
Impact:
- Melatonin supplementation enhances bone tissue reactivity, particularly in aging individuals.
- The findings suggest melatonin may play a role in mitigating age-related decline in bone properties.
- This research opens avenues for exploring melatonin as a therapeutic agent for bone health in aging populations.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:19The Effect of Aging on Tissues
4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:40Bone Remodeling
41.0K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:31Osteoclasts in Bone Remodeling
4.7K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

01:17Hormones and Bone Tissue
4.2K
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...
