Abstract 한글 요약
The presence of tumor heterogeneity is a critical issue that restricts the success of targeted therapies and negatively impacts patient outcomes. Recent studies have concentrated on the development of multi-epitope peptides that exhibit considerable overexpression in cancerous tissues with the aim of activating immune cells and utilizing immune-mediated responses to effectively suppress tumor growth. In this study, genes with increased expression in colorectal cancer (CRC) were identified using GEO data and R software. Following overexpression confirmation of APCDD1, we identified epitopes from the protein that can be recognized by various MHC molecules and presented on APC cell surfaces. Subsequent to expression and purification of the multi-epitope peptide and investigation on the BALB/c mice harboring tumor xenograft, obtained results showed a significant reduction in tumor growth, mitotic cell count, angiogenesis, metastasis, and an increase in Tumor-Infiltrating Lymphocytes (TILs) in the tumor microenvironment. Overall, the finding highlight the potential of multi-epitope peptide in CRC immunotherapy, where it may address the significant challenge of tumor heterogeneity.
