Fig. 1: LNT suppresses NB growth in in vivo tumor models.

A Tumor-bearing model mice was injected with PBS or LNT. Tumors were resected for size measurement on 28th day after injection. B Tumor growth curves of two groups of mice were plotted to show the difference of tumor volume. C The weight of tumors in LNT group and Control group was measured. D The positive expression of proliferation marker (ki67) in tumor tissues isolated from two groups of tumors was detected by IHC. **P < 0.01.
