Implantation of the HOXB7-overexpressing cell line MGC-803-B7 resulted in significantly faster tumor growth than in the MGC-803-NC group, and the tumor volumes for MGC-803-B7 (930.53 ± 129.20 mm3) were significantly larger than the MGC-803-NC control (186.31 ± 103.82 mm3) (Figure 3C–3D; t-test, P<0.05). This evidence concerns the gene HOXB7 and neoplasm.
