Abstract

Cancer prevention using natural micronutrition on epigenetic mechanisms primarily revolves around plant extracts. However, the role of macronutrition, including animal peptides, on epigenetic modification in cancer has been elusive. In traditional Chinese medicine, the soft‑shelled turtle has a long‑history of being a functional food that strengthens immunity through unknown mechanisms. The present study aimed to investigate the impact of soft‑shelled turtle peptide on microRNA (miRNA) expression in gastric cancer (GC) cells and to analyze the potential anticancer mechanisms for GC. Affymetrix GeneChip miRNA 3.0 Array and quantitative polymerase chain reaction were used to detect the miRNA expression profile in human GC AGS cells treated with the soft‑shelled turtle peptide. The results demonstrated that 101 miRNAs (49 upregulated miRNAs and 52 downregulated miRNAs) were significantly differentially expressed in the AGS cells following soft‑shelled turtle peptide treatment. Several tumor suppressor miRNAs were upregulated markedly, including miRNA‑375, let‑7d, miRNA‑429, miRNA‑148a/148b and miRNA‑34a. Pathway analysis indicated that soft‑shelled turtle peptide may function with anticancer properties through the Hippo signaling pathway and the forkhead box O signaling pathway. Therefore, these results demonstrated that soft‑shelled turtle peptide has the capacity to influence cancer‑related pathways through the regulation of miRNA expression in GC cells.
