The aging of today's global population is accelerating, leading to a higher incidence of some diseases related to aging, such as chronic diseases, neurodegenerative diseases, cardiovascular diseases, etc. However, people at the same age may show different disease expressions, and one possible factor is due to differences in the aging process of different individuals, which means that the actual age of individuals is the same but their biological age may be different.

Then understanding the biological age and aging rate of different individuals, the latter is also known as age acceleration, can help us identify high incidence groups and is important for early disease prevention. As a biological service provider for aging research, we can provide services for association studies between age acceleration and disease expression on the basis of DNA methylation analysis.
