SLC5A1 and carcinoma: Towards this, we compared the growth of subcutaneously implanted xenografts of MCF7, MCF7-TAMR1, SGLT1 knockdown in MCF7-TAMR1, and SGLT1-overexpressing MCF7 cells as Mφ macrophage cocultures since this system mimics interactions between carcinoma cells and effects on TAM polarization (Fig. 5A).
