Figure 7. Rg3-CNT suppresses the cell growth of TNBC in vivo. (A–C) The nude mice (n = 5) were injected with the MDA-MB-231 cells treated with Rg3-CNT or CNT. (A, B) Representative images and tumor volume were shown. (C) The expression of PD-L1 was detected by qPCR assays in the tumor tissues. ** P < 0.01.
