Fig. 7From: Study of the tumor microenvironment during breast cancer progressionThe expression of tumor progression markers. RNA was extracted from different stages of breast cancer tissues and normal group. The expression levels of inhibitory markers including FASL, IDO, SOCS1, VEGF, and CCR7 were determined by qPCR. a The mRNA concentration of above factors was compared between tumor and normal subjects. b Moreover, we investigated the expression levels of genes in different stages of patients versus control. IDO indoleamine 2,3-dioxygenase, FASL fas ligand, VEGF vascular endothelial growth factor, SOCS1 suppressor of cytokine signaling 1, CCR7 C-C motif chemokine receptor 7. *Pv < 0.05, **Pv < 0.01Back to article page
