The synthetic tetrapeptide Cardiogen (sequence Ala-Glu-Asp-Arg, often abbreviated AEDR) has emerged in the literature as a bioregulatory peptide with intriguing properties in the realm of cardiovascular biology and beyond. Research indicates that this peptide might influence cellular proliferation, modulate apoptotic signaling, and participate in stress-response pathways. In this article, we present an overview of speculated characteristics of Cardiogen, propose potential applications in diverse research domains (e.g., regenerative science, molecular biology, cellular aging, metabolic research), and highlight speculative directions for further investigation.
