Human Antigen R (HuR): A New Regulator of Heme Oxygenase-1 Cytoprotection in Mouse and Human Liver Transplantation
*Purpose: Ischemia-reperfusion injury (IRI) represents a risk factor in liver transplantation (LT). We have shown that overexpression of heme oxygenase 1 (HO-1) mitigates hepatic IRI…2019 American Transplant Congress
HuR Dictates HO-1 Expression, Modulates Inflammation and Influences Recipient Outcomes in Liver Transplant Patients
Dumont-UCLA Transplant Center, UCLA, Los Angeles, CA
*Purpose: Liver ischemia-reperfusion injury, an innate-immune dominated hepatocellular damage, is a risk factor of early graft dysfunction and rejection in liver transplantation (LT). HuR, an…2018 American Transplant Congress
Recipient HO-1 Deficiency Decreases Post-Transplant Graft HO-1 Expression and Exacerbates Liver Transplant Damage
1Surgery, Liver Transplantation, UCLA, Los Angeles, CA; 2Pathology, UCLA, Los Angeles, CA.
Many preclinical studies on protective functions of heme oxygenase-1 (HO-1; hsp32) in orthotopic liver transplantation (OLT) have encouraged application of HO-1 inducing regimens in clinical…2017 American Transplant Congress
Myeloid HO-1 Orchestrates Liver Graft Function via SIRT1/p53 Signaling: From Mouse-to-Human.
Background/Aim: Although the efficacy of heme oxygenase-1 (HO-1) to combat liver ischemia-reperfusion injury (IRI) in animal models is well-established, cell-specific HO-1 function and mechanisms of…2017 American Transplant Congress
Myeloid HO-1 Regulates M2 Macrophage Activation in Liver Ischemia-Reperfusion Injury (IRI).
Background/Aim: Although anti-inflammatory macrophage differentiation (M2) from pro-inflammatory (M1) phenotype is critical for heme oxygenase-1 (HO-1) cytoprotection, the role of cell type-specific HO-1 induction remains…2015 American Transplant Congress
HO-1 Modified Macrophages Promote Autophagy by Activating Sirt1/TGF-β/Smad4 Signaling in Ischemia-Stressed Mouse Liver Transplants
Background: Although heme oxygenase-1 (HO-1) is known to induce alternative macrophage activation towards an anti-inflammatory M2 phenotype, the underlying mechanisms remain elusive. Autophagy may play…2015 American Transplant Congress
Impact of HMOX1 Genetic Variation in Pancreas Transplant Recipients On Long-Term Graft Outcome
Variation within the heme oxygenase 1 (HMOX1) gene, essential for heme catabolism and a known inflammatory and immune regulator, is proposed to play a role…2015 American Transplant Congress
Myeloid Cell-Specific Heme Oxygenase-1 Is Crucial for Hepatoprotection in Liver Ischemia-Reperfusion Injury
Background and Aim: Heme oxygenase-1 (HO-1), an anti-oxidant enzyme, is essential in tissue resistance against innate immunity driven ischemia-reperfusion injury (IRI). Our group was the…
