Table 1. . The strategies to block CD73 in tumor cells and tumor-bearing animals.

Tumor cell Cancer type Treatment Efficiency
MDA-MB-231 Human breast cancer APCP Xenograft of MDA-MB-231 cells in nude mice with APCP treatment have a lower volume and weight than those of the control group [50]
    Anti-CD73 (AD2) Anti-CD73 monoclonal antibody inhibits metastasis formation by a mechanism independent of CD73 catalytic activity but fails to inhibit primary tumor growth [110]
    SiRNA-CD73 CD73 siRNA effectively causes MB-MDA-231 tumor growth suppression in vitro and in vitro, prevention of adhesion to extracellular matrix and inhibition of invasion and migration [28,31]
U138MG Human brain glioblastoma APCP In vitro APCP treatment of glioma cells results in a significant reduction of glioma cell proliferation [111]
T24 Human bladder carcinoma APCP In vitro APCP treatment results in a significant decrease of T24 cell number as compared with control cells [51]
GBC-SD Human gallbladder carcinoma SiRNA-CD73 CD73 knockdown inhibits tumor cell proliferation, migration and motility [112]
Glioblastoma Multiforme Human brain cancer SiRNA-CD73 CD73 knockdown reverses multiple-drug resistance of GBM cells [33]
E0771 Murine breast cancer Anti-CD73 (TY/23) Anti-CD73 monoclonal antibody treatment significantly delays primary E0771 tumor growth in immune-competent mice [24]
ID8 Murine ovarian cancer APCP A survival advantage is observed in ID8-bearing mice with APCP treatment in vivo [25]
    Anti-CD73 (TY/23) Peritoneal ID8 tumor model showed a median 146-day survival of mice treated with TY/23 as superior to that of mice without treatment [18]
ID8-OVA Murine ovarian cancer SiRNA-CD73 CD73 knockdown renders tumor cells more susceptible to T-cell killing [25]
B16-SIY Murine melanoma APCP In vivo APCP treatment effectively suppresses B16-SIY tumor growth [18]
    Anti-CD73 (TY/23) Delayed tumor growth was observed in B16-SIY bearing mice treated with the anti-CD73 mAb TY/23 as compared with a control group [18]
B16F10 Murine melanoma APCP In vivo APCP treatment induces significant tumor regression by promoting the release of Th1- and Th17-associated cytokines in the tumor microenvironment [104]
    CD73 ablation CD73 ablation significantly suppresses the growth and metastasis of B16F10 [18]
4T1.2 Murine breast cancer Anti-CD73 (TY/23) Anti-CD73 monoclonal antibody treatment significantly delays primary 4T1.2 and E0771 tumor growth in immune-competent mice and significantly inhibits the development of spontaneous 4T1.2 lung metastases [24]
4T1 Murine breast cancer siRNA-CD73 loaded nanoparticle Decreased expression of tumor cell CD73 contributes to decreased tumor growth and metastasis and improves animal subject survival [113,114]
MCA-induced fibrosarcoma Murine Anti-CD73 (TY/23) Anti-CD73 monoclonal antibody treatment effectively suppresses growth of established 3-methylcholanthrene (MCA)-induced tumors [19]
    CD73 ablation CD73 deficiency suppresses the development of MCA-induced fibrosarcomas [19]
TRAMP-C1 Murine prostate cancer Anti-CD73 (TY/23) Anti-CD73 monoclonal antibody treatment suppresses the growth of TRAMP-C1 prostate tumors and inhibits the development of TRAMP-C1 lung metastases [19]
Prostate cancer Murine CD73 ablation CD73 deficiency also suppresses prostate tumorigenesis in TRAMP transgenic mice [19]
LWT1 Murine melanoma Anti-CD73 (TY/23) Anti-CD73 monoclonal antibody treatment significantly decreases metastatic burden as compared with control treatment [115]
    CD73 ablation CD73 ablation improves metastatic control as compared with wild-type mice [115]
MC38-OVA Murine colon cancer CD73 ablation CD73 ablation significantly suppresses the growth of MC38-OVA [26]
EL4/EG7 Murine lymphoma CD73 ablation CD73 ablation significantly suppresses the growth of EL4/EG7 [18,26]
AT-3 Murine mammary tumor CD73 ablation CD73 ablation significantly suppresses the growth of AT-3 [26]
