The results revealed that the tumor volume and weight of the HCCLM3 cell-derived xenografts treated with 25 mg/kg CD151 mAb 9B was much lower than that in of the HCCLM3 cell-derived xenografts treated with PBS (Figure 4A, B and C;741.3 ± 191.4 mm3vs. 1195.2 ± 202.5 mm3, 3.42 ± 0.88 g vs. 5.51 ± 0.93 g). This evidence concerns the gene CD151 and neoplasm.
