Abstract

Tetrapeptide H-Ala-Glu-Asp-Arg-OH enhances the expression of cytoskeletal (actin, tubulin, vimentin) and nuclear matrix proteins (lamin A, lamin C) in cultured mouse embryonic fibroblasts by 2-5 and 2-3 times, respectively. Thus, the previously reported cardioprotective activity of this tetrapeptide is determined by its capacity to activate synthesis of cytoskeletal and nuclear matrix proteins, which stimulates cell proliferation and reduces apoptosis.
