Key Findings
- All three peptides increased expression of CXCL12, WEDC1, and ghrelin in senescent prostate fibroblast cultures.
- Peptide T-38 showed the greatest boost among the tested peptides.
- In older cell cultures (after 7 passages), peptide treatment raised protein levels to equal or exceed those in young cultures (after 1 passage).
Practical Outcomes
- For biohackers, the study suggests a possible anti‑aging effect of cardiogen‑type peptides on prostate tissue at the cellular level, but there is no guidance on dosage, delivery, or safety in humans. Until animal or clinical data are available, it remains a theoretical insight rather than an actionable protocol.
Summary
A lab study found that short peptides called T-32, T-38, and cardiogen can boost certain proteins (CXCL12, WEDC1, ghrelin) in aging prostate fibroblast cells, even making their levels higher than in young cells. The effect was strongest for peptide T-38. The work is purely in cell culture and does not include human dosing or safety data.
Abstract
The effect of short peptides T-32, T-38 and cardiogen on the expression of signaling factors of the differentiation of human prostate's fibroblasts (PFM), which are the main cells of its microenvironment--protein CXCL12, WEDC1 and ghrelin in aging cultures has been studied. Confocal laser microscopy has demonstrated that all the investigated peptides possess the ability to actively enhance the expression of the above markers, whose synthesis significantly reduced in senescent cultures. It has been shown that the rate of expression of the studied factors in older cultures (after 7 passages) under the action of the peptides have a tendency to even higher than those of controls (young culture, after 1 passage). Thus, peptide T-38 is the most active among the investigated ones. These studies show promise for detailed development of methods of peptides' regulation of aging and age-correction of violations of functioning of the prostate gland.
