Description
Cardiogen
Synthetic bioactive tetrapeptide bioregulator (Ala-Glu-Asp-Arg) for in vitro research on cardiomyocyte differentiation, myocardial epigenetic gene regulation, cardiac fibrosis modulation, and cellular cardioprotection
Overview & Mechanism of Action (In Vitro)
Cardiogen is a synthetic ultra-short peptide (tetrapeptide) consisting of four amino acids with the sequence (Ala-Glu-Asp-Arg / AEDR), developed within the framework of short peptide bioregulators targeting myocardial tissue. It exhibits high cellular and nuclear membrane permeability, operating primarily through direct epigenetic modulation of chromatin dynamics and nuclear transcription rather than classical surface receptor activation. In molecular cardiology, cellular biogerontology, and regenerative tissue models, it serves as a primary reference standard for studying myocardial homeostasis and tissue remodeling:
- Direct Epigenetic Interaction with Histones & DNA: Rapidly penetrates the nuclear envelope of cardiomyocytes to interact site-specifically with histone complexes (H1, H2B, H3, H4) and nucleotide motifs, enhancing the transcriptional accessibility of genes encoding essential myocardial structural and metabolic proteins.
- Stimulation of Cytoskeletal & Contractile Protein Synthesis: Upregulates the expression of key structural proteins (actin, vimentin, and tubulin) in cardiomyocyte cultures, reinforcing structural scaffolding and functional contractile architecture in vitro.
- Modulation of Cardiomyocyte Proliferation & Apoptosis Suppression: Promotes cellular viability and cell cycle progression (G1/S phase transition) in primary cardiomyocyte lines under hypoxic and ischemic challenge while attenuating pro-apoptotic signaling (such as p53 expression).
- Fibroblast Proliferation Regulation & Anti-Fibrotic Profiling: Selectively regulates cardiac fibroblast hyper-proliferation and attenuates excessive extracellular matrix deposition (collagen types I and III), providing a robust model for investigating the mitigation of fibrotic tissue remodeling following ischemic injury.
