An article in Lancet approaches the DNA  methylation (the incorporation of molecular “marks” on the DNA) who constitutes a marking system that holds instructions on how and when the genetic information contained in the DNA should be read. Unlike the genomic structure, which is inherited, methylation takes place in a process that continues throughout the development of individuals, controlling the expression of genes during their entire life.

A critical process in medicine

DNA methylation is also a critical process in medicine and, in fact, some changes in genome methylation occur with age and are a marker of aging; it could also play a role in the development of some metabolic, autoimmune or neurological diseases, especially cancer.

Use in biotechnology. Deciphering and understanding DNA methylation mechanisms

Methalyzation marker

The genome continues to undergo programmed variations after birth in response to environmental stimuli, so methylation can be used to detect cell death and also — and this may be the most remarkable aspect — to monitor many diseases using a simple blood test that analyses DNA methylation.

DNA methylation genomic incidence

It can generally be said that DNA methylation represents a sophisticated molecular mechanism to determine genetic information because although all cell types in the body contain the same DNA sequence, their methylation patterns are very different. Deciphering and understanding DNA methylation mechanisms is essential to determine how our genes are used in health and disease (see more HERE). It is a matter we have to know in order to be updated on the genetic a genome latest advances.
