We investigated the effects of the angiogenesis inhibitor TNP-470 on human lung
squamous cell carcinoma cell lines H226B and H226Br both in vivo and in vitro.
H226B was established from human lung squamous cell carcinoma and H226Br was
established from a brain metastatic lesion of H226B in nude mice. Nude mice
inoculated with these cells were treated with 30 mg / kg of TNP-470
subcutaneously every other day. At this dose, TNP-470 only significantly
suppressed the growth of H226Br tumor, but not H226B tumor. Attempts to use a
high dose of TNP-470 (100 mg / kg) resulted in a severe loss of body weight.
Immunohistochemical studies showed marked tumor vascularization in H226Br tumor,
but the formation of new blood vessels was suppressed by 30 mg / kg of TNP-470.
Investigation of the mechanism of anti-angiogenic effects of TNP-470 in vivo
showed that the expression and the activity of platelet-derived endothelial cell
growth factor / thymidine phosphorylase (PD-ECGF / dThdPase) in H226Br tumor was
significantly suppressed by 30 mg / kg of TNP-470. Furthermore, TNP-470 inhibited
cell growth of cultured H226Br dose-dependently at concentrations of 1 microg /
ml. Immunoblot analysis revealed H226Br cells gave a stronger PD-ECGF signal than
H226B cells, and the expression of PD-ECGF / dThdPase in H226Br was also
suppressed by treatment with TNP-470 at 0.1 microg / ml. No change in basic
fibroblast growth factor (bFGF) or vascular endothelial growth factor (VEGF) was
noted in these cell lines. Our results suggested that TNP-470 acts, at least in
part, by downregulation of PD-ECGF / dThdPase in this cell line.
