Possible Link in Cardiogen Peptide, Fibroblasts, and Tissue Repair

by | Sep 5, 2022 | Research

Cardiogen is a bioregulatory peptide that may potentially affect fibroblasts, cells that regulate tissue repair and scar formation. Although the focus of Cardiogen peptide research has previously been on its potential impact within the context of cardiovascular diseases, research suggests that it may modulate fibroblast activities, hence its name. Preliminary Cardiogen studies in mouse models suggest that the peptide may potentially increase tumor cell death.


Potential Functions of Cardiogen


Cardiogen Peptide and Cancer Cells

A study on mice with M-1 sarcoma found that after Cardiogen exposure, tumor cells appeared to exhibit higher levels of Apoptosis or programed cell death.[1] During this process, old cells or cells that have the potential to turn cancerous are eliminated. The presence of hemorrhagic necrosis and activation of tumor cell apoptosis may have induced a concentration-dependent inhibition of M-1 sarcoma growth after Cardiogen peptide exposure.[2] The measurements of proliferative activities suggest that the inhibition of tumor growth was not caused by the peptide’s cytostatic potential on the tumor. It is worth noting that the impact appeared concentration-dependent, indicating that the biological product may be absolute.

Cardiogen appears to induce apoptosis in tumor cells and may play a subtle role in tumor selection due to their increased and unusual vascular supply, placing Cardiogen at the forefront of certain cancer research studies.


Cardiogen Peptide and the Heart

Cardiogen has been suggested to stimulate cardiomyocyte proliferation while inhibiting fibroblast growth and development in the heart, resulting in less scar formation and potentially better long-term cardiac remodeling outcomes after heart failure. Furthermore, Cardiogen may reduce p53 protein expression, lowering apoptosis rates.


Cardiogen Peptide and the Prostate

Cardiogen, in conjunction with peptides with similar functions, has been suggested in micropropagation studies to modulate the expression of signaling factors in prostate fibroblasts.[3] Signaling factors are factors that promote the development and progression of prostate cancer. These levels are considered to be critical in establishing a favorable microenvironment within tumors, which mat contribute to the development and progression of prostate cancer. According to research, signaling factors may be regulated in senescent and aging fibroblasts.[4] Research suggests that Cardiogen may stabilize signaling molecule levels to match or improve what is in young cultures.
