This process can influence whether genes are active or inactive without changing the underlying DNA sequence.
DNA methylation plays a critical role in several biological functions, including embryonic development, cellular differentiation, genomic stability, and aging. Changes in DNA methylation patterns have also been associated with various health conditions, including cancer, neurological disorders, and metabolic diseases.
Growing scientific interest in DNA methylation has expanded its applications in biomedical research, disease investigation, and the development of diagnostic tools. Researchers are increasingly examining methylation patterns to identify potential biomarkers for early disease detection, monitor disease progression, and support personalized medicine approaches.
Technological advancements in DNA sequencing, methylation profiling, and molecular analysis are improving the ability to study epigenetic changes with greater accuracy and efficiency. These developments are creating new opportunities for research laboratories, healthcare institutions, biotechnology companies, and pharmaceutical organizations.
