Downregulation of HDAC6 mitigates lung ischemia/reperfusion injury depending on activation of Nrf2/HO-1 signaling pathway and inactivation of ERK/NF-κB signaling pathway

Abstract

Lung ischemia/reperfusion injury (LIRI) is a pathological process caused by the deficiency and subsequent reperfusion of oxygen and blood to the lung. Literature reports that the catalytic activity and expression of HDAC6 can be induced in response to IRI. HDAC6 inhibition confers protective effects against a series of IRI and also exerts pulmonary protection against various lung damage. The present study was formulated to investigate the functional role of HDAC6 inhibitor in LIRI and to probe into the intrinsic mechanisms underlying the protective role of HDAC6 inhibitor against LIRI.
