Patient-derived pancreatic tumor bacteria can tolerate and metabolize 5-FU and gemcitabine, major chemotherapy drugs.
Bacterial isolates from IPMNs are found to diminish the cytotoxic effects of these chemotherapeutic agents on cancer cell lines.
Whole-genome sequencing identifies Gammaproteobacteria strains enriched in drug resistance and metabolism pathways.
Findings highlight the significant interaction between tumor-associated bacteria and chemotherapy, suggesting new directions for treatment enhancement.
