What the research examined
One paper constructed computational models of interactions between short peptides and DNA. Another examined chromosomal measurements in cultured cells exposed to a tetrapeptide described as Prostamax. These approaches explore possible molecular interactions at different experimental levels.
How to interpret the findings
A docking model predicts possible interactions rather than demonstrating them in an organism. Chromatin measurements in culture do not establish organ-specific rejuvenation, clinical benefit, or safety.
