title: Inhibition of lung homing of B16F10 by pentoxifylline, a microfilament depolymerizing agent.
abstract: B16 melanoma has proved to be an ideal model for investigating metastasis. The parental B16F1 line grows as a localized subcutaneous tumor in C57BL/6 or DBA/2 mice. However, by means of successive intravenous transplantation, a subline B16F10 has been established. This shows preponderant lung homing when transplanted by intravenous route into C57BL/6 mice. In this paper we have shown that pentoxifylline (PTX; Hoechst), a microfilament depolymerising agent can inhibit significantly this lung homing of B16F10 cells. It also had a marginal inhibitory effect on subcutaneous tumor growth.
