Abstract
The present invention relates to a novelGRA8-derived recombinant peptide, and a pharmaceutical composition and functional food for preventing or treating cancer, which includes the same as an active ingredient. TheGRA8-derived recombinant peptide according to the present invention is a novel recombinant peptide in which a specific mitochondrial targeting sequence and an ATP5A1/SIRT3 sequence of GRA8 are conjugated to an acidity-triggered rational membrane (ATRAM), and has considerably improved efficacy in which an inhibitory concentration 50 (IC50) is improved up to 200-fold (in vitro) or 500-fold (in vivo), compared with a conventional GRA8-derived peptide (rGRA8). In addition, since the peptide treatment shows a notably distinct therapeutic effect in mouse models with cancer, the peptide may be effectively used in a pharmaceutical composition or functional food for preventing or treating cancer.
