Key Findings
- Short peptides (2-4 amino acids) can regulate gene expression by directly interacting with DNA in a sequence-specific manner
- Peptides bind complementarily to specific nucleotide sequences in gene promoter regions, influencing transcription
- Different peptide sequences show preferential binding to different DNA motifs, providing a basis for tissue specificity
- The mechanism involves both direct DNA binding and chromatin remodeling (heterochromatin decondensation)
- This represents the core theoretical framework of the Khavinson bioregulation paradigm
Study Design
Narrative review summarizing the author's research program on short peptide-DNA interactions and gene expression regulation. Draws on molecular modeling, in vitro binding studies, and cell culture experiments conducted by the Khavinson group.
Limitations
- Single-author review of the author's own research program
- The proposed DNA-binding mechanism has not been independently validated
- Published in a journal with limited international visibility
- No independent structural biology confirmation of peptide-DNA binding models
Clinical Relevance
Provides the theoretical underpinning for all Khavinson short peptide bioregulators. Understanding this framework is necessary for contextualizing claims made about individual peptides (Vilon, Livagen, Cortagen, etc.), but the theory itself remains unvalidated by independent research groups.
Methodological Note: This review originates from the Khavinson bioregulation group (Institute of Bioregulation and Gerontology, St. Petersburg). Independent replication by Western laboratories is lacking.
