Figure 6. Overexpression of AK7 inhibits RCC growth and enhances anti-PD1 efficacy. (A) Schematic diagram of establishment of mouse subcutaneous tumor model in each group. (B) Three lentiviruses were designed to overexpress AK7 expression in RENCA cell lines, and their overexpression efficiency was verified by qRT-PCR. (C) Images of subcutaneous tumors in each group. (D, E) Analysis of subcutaneous tumors in the respective groups. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
