Cardiogen
Heart Research only Animal studies Synthetic short peptide (Cytogen)
Also called AEDR peptide
A four-amino-acid Khavinson peptide associated with heart tissue. Studies report effects on fibroblasts, the cells that handle repair and scarring, and on heart muscle cell growth in aged tissue cultures. One rat study found higher rates of tumor cell death.

How it works
A Khavinson short peptide: at two to four amino acids it is small enough to pass through cell and nuclear membranes intact. The proposed mechanism is that it binds specific sites on nuclear DNA and changes which genes are switched on in its target tissue, rather than acting on a surface receptor the way most peptides do.
Where it acts
HeartThe library groups this compound under Heart. The diagram shows that target, not every tissue it reaches.
