Antitumor Effect of IP-10 by Using Two Different Approaches: Live Delivery System and Gene Therapy

Abstract

Our data indicates that IP-10 immunotherapy is a promising strategy for breast cancer treatment, as shown in the 4T1-implanted BALB/c mouse model. However, the L. tarentolae-(IP-10-EGFP) live delivery system requires dose modifications to achieve efficacy in the applied regimen (six injections in 3 weeks). Our results indicate that the arginase assay could be a good biomarker to differentiate tumoral tissues from the normal ones.
