Abstrakt: Short peptides vesugen and D-7 have stimulated proliferation-associated protein Ki-67 decreased during aging in tissue-specific cell cultures received from young and old animals and in dissociated vascular endothelial cell cultures. Peptides vesugen and D-7 have interacted with promoter region of MKI67 gene coding protein Ki-67 that was obtained using methods of molecular docking. Both peptides have contacted with core promoter 5'-agcctcaaccatcaggaaaacaagagt-3' located in MKI67 gene from -14 to +12 base pairs relative to the transcriptional initiation site through sequence CATC(ENSG00000148773). Thus, vasoprotective effect of peptide vesugen revealed previously in elder people could be realized through epigenetic regulation of Ki-67 gene expression.
