Far-infrared radiation alleviates cisplatin-induced vascular damage and impaired circulation via activation of HIF-1α.

ABSTRACT: Severe vascular damage and complications are often observed in cancer patients during treatment with chemotherapeutic drugs such as cisplatin. Thus, development of potential options to ameliorate the vascular side effects is urgently needed. In this study, the effects and the underlying mechanisms of far-infrared radiation (FIR) on cisplatin-induced vascular injury and endothelial cytotoxicity/dysfunction in mice and human umbilical vein endothelial cells (HUVECs) were investigated. An important finding is that the severe vascular stenosis and poor blood flow seen in cisplatin-treated mice were greatly mitigated by FIR irradiation (30 minutes/day) for 1-3 days. Moreover, FIR markedly increased the levels of phosphorylation of PI3K and Akt, and VEGF secretion, as well as the expression and
