Abstract
In the process of protein transcription and translation, various protein complexes bind to DNA, and all processes are precisely controlled. Among the proteins constituting this complex, a peptide derived from eukaryotic initiation factor (eIF) 2 was synthesized. In addition, in order to increase the efficiency of transduction of this peptide into cells, peptides with polyarginine, one of the protein transduction domains (PTD), were synthesized. Cell growth inhibition was confirmed in HER2 positive breast cancer (SK-Br-3) and HER2 negative breast cancer (MDA-MB-231), and cardiomyocytes (H9c2). The peptide with polyarginine had high transduction efficiency in all cells, and had excellent cancer cell growth inhibitory effects. The peptide used in this study might be useful peptide therapeutics for the treatment of cancer through future research.
