YVPGP is an oligopeptide extracted from Anthopleura anjunae. It exhibits significant anti-tumor activity by mediating the PI3K/AKT/mTOR signaling pathway. YVPGP can arrest DU-145 cells in the S phase and induce apoptosis (apoptosis) through mitochondrial and death receptor pathways (caspase3, 7, 8, 9). It effectively inhibits tumor growth in a DU-145 xenograft mouse model, showing potential for prostate cancer research.
