Tumor growth inhibition effect of miRNA34a delivery. A Tumor volume graph of Balb/c nude mice (mean ± SD, n = 3). Injections were given twice a week for a total of 5 times (red arrows: days of injection). B MR images 37 days after tumor modeling. *P < 0.05 (vs saline), **P < 0.01 (vs MNVs with scrambled miRNA)
