Fig. 5. The antitumor evaluation on the SAS cell bearing mice after the single intratumoral administration of HBG, empty MITO-Porter, free rTPA, and rTPA–MITO-Porter. (A) The profile of the relative tumor volume of different treatment groups. (B) The representative photographs of SAS cell bearing mice at the end of the observation period. (C) Changes in body weight during the observation period. The error bars indicate S.D. (n = 4–6; n.s. = not significant; *p < 0.05; **p < 0.01 by ANOVA followed by SNK-test).
