摘要:
Calcineurin inhibitors (CNIs) may promote post-transplantation cancer through altered expression of cytokines and chemokines in tumor cells. We found that there is a potential cross-talk among CNI-induced signaling molecules and mTOR. Here, we utilized a murine model of post-transplantation cancer to examine the effect of a combination therapy (CNI. +. mTOR-inhibitor rapamycin) on allograft survival and renal cancer progression. The therapy prolonged allograft survival; and significantly attenuated CNI-induced post-transplantation cancer progression, with down-regulation of mTOR and S6-kinase phosphorylation. Also, rapamycin inhibited CNI-induced over-expression of the angiogenic cytokine VEGF, and the chemokine receptor CXCR3 and its ligands in post-transplantation tumor tissues. © 2012 Elsevier Ireland Ltd.
