In agreement with the mouse model, the amount of CD163+/CD204+macrophages and ATX were much higher in grade III human breast carcinomas compared to grade I. Our work provides the first in vivo preclinical evidence showing that IOA-244 is a potential highly effective drug for breast cancer treatment and depending on the phase of the tumour can be used either as a single agent or as a combinatorial regimen. The gene discussed is CD163; the disease is breast carcinoma.
