Fedoreyeva L I, et al. · Biochemistry. Biokhimiia · 2011
The study demonstrated that Pinealon can penetrate the nucleus of HeLa cells and interact with DNA, suggesting its potential role in regulating gene activity.
Key findings
- 01Peptides labeled with fluorescence were able to penetrate HeLa cells, highlighting their ability to enter cell nuclei.
- 02Different peptides showed varying effects on the fluorescence of DNA, suggesting specific interactions with nucleic acids.
- 03Some peptides preferentially bind to DNA sequences associated with cytosine methylation, which may influence gene regulation.
