Looking at the change in the external size of the xenograft tumor summarized in Figure 5C, both NCP and p-FAK/GNP showed a gradual reduction in the size of the tumor, with a statistically significant difference of about 55% compared to the pre-treatment size after 3 weeks, and a tumor about 41% of its original size remained after 4 weeks. The gene discussed is PTK2; the disease is neoplasm.
