Summary
Abnormal protein glycosylation accelerates aging and disease, including cancer and cardiovascular disease (CVD). Future interventions targeting these pathways, alongside lifestyle changes like smoking cessation, may reduce disease risk and promote longevity.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics of Aging
Background:
- Glycosylation is a crucial posttranslational modification essential for protein function, cell adhesion, and stability.
- Aberrant glycosylation patterns are increasingly linked to the aging process and the pathogenesis of age-related diseases.
- Genetic variations within glycosylation pathways are associated with cancer, cardiovascular disease (CVD), and overall vulnerability to disease.
Purpose of the Study:
- To explore the role of glycosylation in aging and disease.
- To investigate the impact of genetic variants on glycosylation-related diseases.
- To identify potential therapeutic strategies targeting glycosylation pathways for disease prevention and healthspan extension.
Main Methods:
- Review of existing literature on glycosylation, aging, and disease.
- Analysis of genetic studies identifying variants in glycosylation pathways.
- Examination of lifestyle factors and interventions affecting glycosylation.
Main Results:
- Abnormal glycosylation significantly contributes to aging and diseases such as diabetes, CVD, neurological disorders, and cancer.
- Specific genetic variants in glycosylation pathways are implicated in disease development and progression.
- Lifestyle modifications, including smoking cessation, can reverse detrimental epigenetic changes in glycosylation pathways.
Conclusions:
- Targeting glycosylation pathways holds promise for future therapeutic interventions to mitigate age-related disease risk.
- Maintaining normal glycosylation through diet, vitamins, and antioxidants may support cellular repair and healthy aging.
- Understanding the genomics of aging and glycosylation is key to developing strategies for enhanced healthspan.

17.3K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

01:25Protein Glycosylation
8.3K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

3.2K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

01:19The Effect of Aging on Tissues
3.0K
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...

4.2K
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,...
