HO-1/SIRT1/p53 Axis Regulates Macrophage Activation and Attenuates Liver Ischemia-Reperfusion Injury in Mice.
K. Nakamura,¹ M. Zhang,² B. Ke,¹ S. Kageyama,¹ R. Busuttil,¹ J. Araujo,² J. Kupiec-Weglinski.¹
¹Surgery, Liver Transplant, University of California-Los Angeles, Los Angeles, CA; ²Medicine, Division of Cardiology, University of California-Los Angeles, Los Angeles, CA.
Background/Aim: The mechanism by which macrophage heme oxygenase-1 (HO-1)-Sirtuin1 (SIRT1) signaling promotes resistance against inflammation response in liver ischemia-reperfusion injury (IRI) remains elusive. As tumor…

Damage Associated Molecular Patterns (DAMPs)-Activated Neutrophil Extracellular Trap Formation Exacerbates Liver Ischemia/Reperfusion Injury
H. Huang, S. Tohme, A. Al-Khafaji, A. Tsung.
Department of Surgery, University of Pittsburgh, Pittsburgh, PA.
Liver ischemia/reperfusion (I/R) injury is a clinically important phenomenon encountered during transplantation that contributes to initial graft function and subsequent allograft rejection. Formation of neutrophil…

Macrophage-Specific SIRT1 Regulates HO-1 Mediated Anti-Inflammatory and Cytoprotective Pathways
K. Nakamura,¹ M. Zhang,² B. Ke,¹ R. Busuttil,¹ J. Araujo,² J. Kupiec-Weglinski.¹
¹Surgery, Liver Transplant, University of California, Los Angeles, Los Angeles, CA; ²Medicine, Division of Cardiology, University of California, Los Angeles, Los Angeles, CA.
Background/Aim: Sirtuin1 (SIRT1), a NAD+-dependent type III histone/protein deacetylase, is essential for resistance against liver ischemia-reperfusion injury (IRI). We asked whether SIRT1 may affect cytoprotective…
