Figure Lengend Snippet: Fig. 6. PLAU promotes tumor growth in vivo. a Schematic of mice subcutaneous tumorigenesis model. b-d FaDu cells were transplanted subcutaneously into nude mice and divided into NC, UKI-1 and Ro 08-2750 groups (UKI-1 and Ro 08-2750 inhibit PLAU and NGF, respectively). The corresponding drugs were injected intraperitoneally on days 1, 4, 7, 10, 13, 16 and 19, the tumors were removed on day 22 and the weight and volume of subcutaneous tumors were measured. e-g The same method was adopted for Tu686 cells as in b-d. h-l Representative immunohistochemical staining of Ki67, PLAU, NGF, PGP9.5 and statistical analysis of respective staining intensity scores. m Schematic overview of interaction between nerve cells and HNSCC cells. Briefly, HNSCC cells have the capability to secrete PLAU and NGF to nerve cells, facilitating the development of PNI and subsequently enhancing tumor advancement. On this basis, the inhibition of PLAU and NGF through UKI-1 and Ro 08-2750 has proven to be efficacious in impeding tumor progression. *P < 0.05, **P < 0.01, ***P < 0.001.
