Abstract
Aim. The growth of gliomas depends on the balance of factors stimulating or inhibiting angiogenesis, tumor cell invasion and proliferation. The administration of endogenous inhibitors to experimental human gliomas in animal models resulted in a significant inhibition of tumor growth. It is becoming apparent that resistance can develop over time to many types of endogenous inhibitors and seems to be influenced by the tumor type and system of delivery. Methods. We recently isolated a potent endogenous inhibitor, called human PEX, from human glioma cells in culture. Human PEX is a potent inhibitor of angiogenesis, tumor and endothelial cell proliferation and migration. In this paper, we investigated the ability of human PEX to sustain inhibition of glioma growth for a prolonged period of time. We initially developed a recombinant form of the inhibitor and showed that this form had similar in vitro and in vivo activities to the natural one. Human PEX was then administered to nude mice intr...File | Dimensione | Formato | |
