If the DNA does not change (radically) over the life of an individual, so that changes in cellular transcription across the age?
Propose a study to develop a data base with proteins that change (in amount or structure) over the age and their respective genes. This information will be available to researchers who can fix and add relevant data.
In the laboratory: animal tissues in Petri dishes (or organisms). Have their cell cycle analyzed and compared with other samples epigenetically altered. The genes of the cells under study that are most active in the mature stage or elderly, will be silenced (or enabled depending on the case) for the most common genes in young beings. The results were compared and shared in the database.
