Synergistic combination of amino acids and gemcitabine enhances cytotoxicity to PDAC cells
(A) Treatment efficacy comparison of AA and GEM. AA, histidine and isoleucine; GEM, gemcitabine.
(B) Adjuvant efficacy of combined AA + GEM treatment on tumor cells.
(C and D) Flow cytometric analyses with 7AAD/Apopxin/CytoCalcein-FITC assay for apoptosis and necrosis on tumor cells in different treatment conditions.
(E) Cell morphology changes upon AA treatment.
(F) Mitochondrial activity shifts due to AA treatment. HPNE, hTert-HPNE (nonmalignant pancreas epithelial); MIA, MIA PaCa-2 (malignant pancreas epithelial); NT, no treatment control; AA, histidine and isoleucine; GEM, gemcitabine.
