Galectin-3, osteopontin and successful aging.
Clinical Chemistry and Laboratory Medicine
|October 20, 2015
Summary
Lower levels of galectin-3 and osteopontin indicate successful aging. These biomarkers may predict longevity and aid in developing anti-aging therapies.
Area of Science:
- Biogerontology
- Biomarker Discovery
- Aging Research
Background:
- Exceptional longevity (100+ years) free of chronic diseases defines successful aging.
- Identifying biomarkers for successful aging is medically significant.
Purpose of the Study:
- To investigate serum levels of galectin-3 and osteopontin in centenarians who are free of age-related diseases.
- To determine if these biomarkers predict successful aging.
Main Methods:
- Serum galectin-3 and osteopontin levels were measured in centenarian 'dodgers' (n=81) and healthy controls (n=41).
- Statistical analyses, including logistic regression and AUC, were used to assess biomarker predictive power.
Main Results:
- Centenarian 'dodgers' had significantly lower galectin-3 and osteopontin levels compared to controls.
- The combination of galectin-3 and osteopontin was a significant predictor of successful aging (AUC=0.86).
Conclusions:
- Lower galectin-3 and osteopontin levels are associated with successful aging.
- These biomarkers show potential for predicting longevity and informing personalized anti-aging strategies.

Aging
1.0K
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The 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...

Glycosaminoglycans
7.7K
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

Osteoclasts in Bone Remodeling
4.8K
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...

Proteoglycans
5.2K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Pharmacodynamics in Geriatric Patients: Effects of Age
319
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...
