Abstract

High mobility group box 1 (HMGB1) is a nuclear protein released from stressed or damaged cells that activates inflammatory cascades involved in the pathogenesis of liver ischemia reperfusion (I/R) injury. In efforts to develop strategies aimed at preventing its release from ischemic cells following I/R, we studied the use of cisplatin, a member of the platinating chemotherapeutic agents capable of inducing DNA lesions that have high binding affinities for high mobility group proteins inside the nucleus of cells. In addition to demonstrating that cisplatin prevents liver damage associated with liver I/R by sequestering HMGB1 inside the nucleus of ischemic cells, cisplatin also alters cell survival signaling through autophagy. Our results provide a potential approach involving the use of platinating agents and their effects on autophagy in mitigating the deleterious effects of ischemia reperfusion-mediated disease processes.
