MiR-29b inhibits leukemic growth in vivo. (A) Diagram illustrating the experimental design of the mice xenograft experiment. (B) Graphic representing tumor volumes at the indicated days during the experiment for the 3 groups: mock (n = 6), scrambled (n = 12), and synthetic miR-29b (n = 12). (C) Tumor weight averages between scrambled and synthetic miR-29b-treated mice groups at the end of the experiment (day 14). P values were obtained using t test. Bars represent SD. (D) Photographs of 2 mice injected with miR-29b (left flank) or scrambled (right flank).
