DNA methylation and age-related bone metabolism imbalance: mechanisms and proposed interventions
According to this abstract, DNA methylation links aging-related inflammation and oxidative stress to an imbalance between bone-forming and bone-resorbing cells, and proposed interventions include low-dose methyltransferase inhibitors, folate and cobalamin, and CRISPR/dCas tools, though off-target effects and low delivery efficiency remain challenges.

Methylation patterns with advancing age
The abstract states that aging can cause age-related bone diseases such as osteoporosis. DNA methylation, described as a core epigenetic regulatory mechanism, is said to influence gene expression and thereby the pathological process of aging-induced bone metabolism imbalance. Using S-adenosylmethionine as a methyl donor, it reportedly shows hypomethylation in genomic repetitive regions and abnormal methylation in CpG islands of promoters of key bone metabolism genes as age advances. An "epigenetic clock" built on these features is said to predict an individual's biological age accurately.

Osteoblast-osteoclast balance and a proposed cycle
In bone metabolism, DNA methylation is said to disrupt the osteoblast-osteoclast balance by targeting key factors. These abnormalities are described as driven by aging-related inflammation and oxidative stress, while bone loss feedback is said to worsen epigenetic disorders, forming a vicious cycle. The abstract presents this as a mechanistic account; it reports no human study testing whether breaking this cycle prevents bone disease.

Proposed interventions and named challenges
Targeted intervention strategies are said to show significant potential for bone metabolism-related issues. Low-dose DNA methyltransferase inhibitors are reported to improve bone metabolism; nutrients such as folate and cobalamin are said to maintain methylation homeostasis by optimizing one-carbon metabolism pathways; and CRISPR/dCas technology is described as enabling precise regulation at the cellular and animal levels, thereby affecting bone metabolism. The abstract states that existing strategies still face off-target effects and low delivery efficiency, and that future research must deepen mechanistic studies, optimize intervention methods and promote translation into clinical prevention and treatment of osteoporosis.
