Figure 4From: Lentiviral-mediated RNA interference targeting stathmin1 gene in human gastric cancer cells inhibits proliferation in vitro and tumor growth in vivoSilencing effect of stathmin shRNA on gastric cancer xenograft in nude mice. MKN-45 cells were transfected with stathmin1 (STMN1) shRNA or, Non-silencing short hairpin RNA (shRNA) and nude mice were inoculated subcutaneously with 2 × 106 cells at two sites per mouse. The tumor mass (xenograft) volume was measured every week from week 3 to week 7. Data are expressed as the (Means ± S.D) and represent six independent experiments. (P < 0.05 vs Non-silencing shRNA, one-way analysis of variance (ANOVA) followed by Tukey’s multiple comparison). (A) Photograph of xenografts dissected from nude mice after 7 weeks subcutaneous inoculation showing suppression growth of cancer cells transfected with stathmin1 shRNA2 rather than non-treated control group. (B) Tumor growth curve showing a significant growth tendency in non-infected group (control) as compared to the stathmin shRNA2 transfected group (p < 0.05).Back to article page
