Synapses are key structures for information transmission between neurons, and changes in methylation may directly affect the formation and function of synapses. In-depth study of the mechanism of DNA methylation in synaptic regulation will help to understand the molecular basis of Pomeranian memory formation and learning ability. In terms of neurotransmitter regulation, changes in DNA methylation may have an impact on neurotransmitter synthesis and release in Pomeranians. Neurotransmitters are chemicals responsible for information transmission in the nervous system, and there may be complex interactions between their regulation and DNA methylation. Understanding these interrelationships will provide a deeper understanding of Pomeranian behavioral differences and learning abilities. By in-depth understanding of the regulatory mechanism of DNA methylation in the Pomeranian nervous system, this study can reveal the molecular basis of its intelligent behavior and learning ability, and provide useful information for further research on the mechanisms of neurological diseases and related treatment strategies. This in-depth exploration is expected to provide new perspectives on the nervous system of Pomeranians and other dog breeds, and also has potential implications for the study of human neurological diseases. 4.3 The role of DNA methylation in the occurrence and development of diseases DNA methylation plays multiple roles in the occurrence and development of Pomeranian diseases, which is of great significance for understanding the molecular mechanisms of the disease and developing corresponding treatment strategies. Abnormal DNA methylation patterns may lead to silencing or overexpression of key genes, thereby affecting Pomeranian health. In disease states, hypermethylation of specific gene regions may lead to silencing of related genes, hindering normal gene expression and cell function. Conversely, hypomethylation may lead to overexpression of genes, triggering abnormal cell behavior and thus promoting disease development. In the study of genetic diseases in Pomeranians, the regulatory mechanism of DNA methylation has become a key focus. Abnormal methylation of specific loci is closely associated with the occurrence of genetic diseases. These genetic variations may lead to changes in the methylation status of certain genes, thereby triggering disease. In-depth study of the relationship between these genetic diseases and DNA methylation can help diagnose potential health problems in advance and provide more precise targeted methods for disease treatment. Changes in DNA methylation patterns can often be used as biomarkers of disease (Asari et al., 2023). By detecting the methylation status of specific genes in Pomeranian DNA, an early indication of disease development can be provided. This provides strong support for the development of individualized treatment plans and prevention strategies. In cancer, neurological diseases, etc., the detection of DNA methylation has become an important means of disease diagnosis and disease stage classification, providing a more accurate tool for Pomeranian health management. An in-depth understanding of the fine regulation of DNA methylation in disease provides new ideas for formulating treatment strategies. Intervention targeting the methylation status of specific loci, through the use of DNA methylation inhibitors or modulators of methylases, may be part of a therapeutic strategy. This provides a more individualized and precise approach to treating specific diseases and is expected to improve the quality of life of Pomeranians. Through in-depth study of the multifaceted role of DNA methylation in disease, this study can better understand the relationship between Pomeranian health and disease. This not only helps to increase awareness of Pomeranian-specific diseases, but also opens up new possibilities for the development of disease treatment strategies. Research in this area will provide new breakthroughs for mutual benefit in the fields of pet medicine and human medicine in the future.
