At day 21, the tumors were weighed; the average weight was 0.585 ± 0.0342 g in the si‐NC group and 0.28 ± 0.029 g in the si‐RBBP4 group, indicating a significant decrease in tumor weight for the si‐RBBP4 group relative to the si‐NC group (p < 0.01) (Figure 10B,C). The gene discussed is RBBP4; the disease is neoplasm.
