To study the effect of lentivirus-mediated EIF3H-siRNA on tumor growth in a xenograft mouse model, 1 week after tumor cell inoculation, we noted tumor growth and 4 weeks after inoculation, five of the six tumor formation in mice of control group was detected and measured, while three of the six were detected and measured in EIF3h knock-down group of mice as shown in Figure 4, xenograft tumor size was as follows (mean ± SD): 1.07 ± 0.49 in control shRNA infected LM3 cell group, and 0.49± 0.19 in the shRNA infected LM3 cell group (Figure 4A, 4B and 4C). This evidence concerns the gene EIF3H and neoplasm.
