The Combination of Recombinant Methioninase and Low-dose Chloroquine Selectively Eradicates Colon-Cancer Cells Without Apparent Toxicity on Co-cultured Normal Fibroblasts

rMETase has selective efficacy against cancer cells in the presence of normal cells, and its efficacy is significantly enhanced selectively on the cancer cells by CQ. The results of the present study suggest the potential for future clinical application of the combination of rMETase and CQ for cancer treatment.
