The studies on functioning of the epigenetic code made it possible to understand that what had been studied was in fact the code of regulation of gene expression. This code is present in its totality and with all its different functions only at the moment when life is formed. In this moment this code could be studied and understood in its global functioning, even if subdivided and divided into different stages of differentiation. In fact if all the substances present in all the different stages of differentiation had been obtained, we would have had the entire epigenetic code available, that is the code able to regulate all the genes of all the cells that make up an entire organism. In other words we would have had the whole code that regulates life: the “Code of Life”. This possibility of studying the epigenetic code in its entirety exists only in the embryo and only in the moment when all the organs and systems differentiate. In that period from a single totipotent stem cell (the fertilized egg) there is a differentiation of all types of stem cells through various stages: pluripotent, multipotent, oligopotent cells, cells in process of definitive differentiation and finally completely differentiated cells. Once the organogenesis is over, it is no longer possible to study the entire epigenetic code in its whole extent and with its different functions. In fact, when the organogenesis is terminated, the epigenetic code is divided into various organs and tissues and every organ contains that part of the code which serves to control and regulate gene expression of the cells of that specific organ, and there is no longer a possibility of studying all the different and incredible functions of the “Code of Life”. Therefore only in that moment when it was decided to study the epigenetic regulation code, i.e. during the period of differentiation of various organs and apparatuses, it became possible to study all the different and incredible regulatory capacities of this code. And that is what has been done, choosing first of all an embryo as a study model for cell differentiation: i.e. in this case the embryo of Zebrafish.
The study of the entire epigenetic code and its functions has led us to fantastic discoveries. These different functions are here briefly described in order to make it clear what great opportunities the study of the code of life offers.
The different regulatory activities of the epigenetic code are listed below:
- Anti-Aging Activity
- Slowing of the multiplication and growth of cancer cells
- Prevention of Neuro-Degeneration
