Aldehyde dehydrogenase 2 attenuates renal injury through inhibiting CYP4A expression.

Renal ischemia-reperfusion injury (IRI) is a prevalent clinical syndrome, yet its underlying pathogenesis remains largely unknown. Aldehyde dehydrogenase 2 (ALDH2), an enzyme responsible for detoxifying lipid aldehydes, has been suggested to play a protective role against IRI. In our study, we observed that Aldh2 knock-out C57BL/6 mice experienced more severe renal functional impairment following IRI.

Hypothermic oxygenated perfusion inhibits CLIP1-mediated TIRAP ubiquitination via TFPI2 to reduce ischemia‒reperfusion injury of the fatty liver.

The use of fatty livers in liver transplantation has emerged as a crucial strategy to expand the pool of donor livers; however, fatty livers are more sensitive to ischemia‒reperfusion injury (IRI). Excessive congenital inflammatory responses are crucial in IRI. Hypothermic oxygenated perfusion (HOPE) is a novel organ preservation technique that may improve marginal donor liver quality by reducing the inflammatory response.

Thrombocytopenia Predicts Poor Prognosis of Liver Transplantation.

Background/aim: Platelets not only participate in physiological hemostasis but also play a major role in liver ischemia-reperfusion injury, liver damage, tissue repair, and liver regeneration. A decrease in platelet count can lead to spontaneous bleeding, infection, and other complications that can seriously impact patient prognosis. Thrombocytopenia has been associated with increased complications after partial hepatectomy, although the effects of thrombocytopenia on patient outcomes remain unclear.

A novel cancer-associated fibroblasts risk score model predict survival and immunotherapy in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is the leading cause of cancer-related death worldwide. Cancer-associated fibroblasts (CAFs) are a special type of fibroblasts, which play an important role in the development and immune escape of tumors. Weighted gene co-expression network analysis (WGCNA) was used to construct the co-expression module.

ALDH2 deficiency exacerbates MCD-diet induced MASLD by modulating bile acid metabolism.

Aldehyde dehydrogenase 2 (ALDH2), an acetaldehyde dehydrogenase in mitochondria, is primarily responsible for metabolizing alcohol-derived acetaldehyde and other endogenous aldehydes. Inactivating ALDH2 rs671 polymorphism is found in up to 8 % of the global population and 40 % of the East Asian population. Recent studies have shown that rs671 SNP mutation in the human ALDH2 gene is associated with an increased risk of metabolic dysfunction-associated steatotic liver diseases (MASLD), but the mechanism remains unclear.

Hypothermic oxygenated perfusion attenuates DCD liver ischemia-reperfusion injury by activating the JAK2/STAT3/HAX1 pathway to regulate endoplasmic reticulum stress.

Background: Hepatic ischemia-reperfusion injury (IRI) in donation after cardiac death (DCD) donors is a major determinant of transplantation success. Endoplasmic reticulum (ER) stress plays a key role in hepatic IRI, with potential involvement of the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway and the antiapoptotic protein hematopoietic-lineage substrate-1-associated protein X-1 (HAX1). In this study, we aimed to investigate the effects of hypothermic oxygenated perfusion (HOPE), an organ preservation modality, on ER stress and apoptosis during hepatic IRI in a DCD rat model.

Successful rescue of renal transplantation with cardiac arrest after electrical storm: A case report.

Rationale: Most patients with end-stage chronic kidney disease are associated with complications such as renal hypertension, renal anemia, hyperkalemia, water-sodium retention, and disorders of acid-base balance after long-term renal replacement therapy, which can lead to increased cardiac burden, some degree of myocardial damage, and finally progress to arrhythmia and heart failure. These are the main reasons why patients with chronic kidney disease are prone to cardiovascular events after renal transplantation.

Patient Concerns: We report a case of sudden onset of ventricular fibrillation on the postoperative second day, with repeated electrical storm accompanied by cardiac arrest during resuscitation, a very long cardiopulmonary resuscitation (CPR) process of 5 hours and 14 minutes, and >20 cycles of cardiac defibrillation.

Construction of a ceRNA network and a genomic-clinicopathologic nomogram to predict survival for HBV-related HCC.

Some lncRNA-associated competing endogenous RNAs (ceRNAs) are considered as potential biomarkers for targeted therapies and prognosis in human cancer. In our present study, we aimed to construct a ceRNA network and establish a genomic-clinicopathologic nomogram to provide insights into the molecular mechanisms and predict survival for HBV-related HCC. The Cancer Genome Atlas (TCGA) database was applied to collect the data of LIHC RNA-seq dataset and miRNA-seq dataset as well as the clinicopathological information.

Mild hypothermia pretreatment extenuates liver ischemia-reperfusion injury through Rab7-mediated autophagosomes-lysosomes fusion.

Liver ischemia-reperfusion (IR) injury is an unavoidable pathological process in transplantation, closely related to poor prognosis. To date, there has been no clear therapeutic measure. We previously reported that mild hypothermia (MH), a widely used therapy, can exert significant protective effect against liver IR injury.

Hypothermic oxygenated perfusion inhibits HECTD3-mediated TRAF3 polyubiquitination to alleviate DCD liver ischemia-reperfusion injury.

Ischemia-reperfusion injury (IRI) is an inevitable and serious clinical problem in donations after heart death (DCD) liver transplantation. Excessive sterile inflammation plays a fateful role in liver IRI. Hypothermic oxygenated perfusion (HOPE), as an emerging organ preservation technology, has a better preservation effect than cold storage (CS) for reducing liver IRI, in which regulating inflammation is one of the main mechanisms.

Bioinformatics analysis of LINC01554 and its co‑expressed genes in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a leading cause of cancer‑related morbidity and mortality globally. Despite the remarkable improvements in comprehensive HCC treatment, the underlying mechanistic details of HCC remain elusive. We screened HCC patients for differentially expressed genes (DEGs) using the Gene Expression Omnibus (GSE113850) and The Cancer Genome Atlas (TCGA) datasets.

Mild Hypothermia Attenuates Hepatic Ischemia-Reperfusion Injury through Regulating the JAK2/STAT3-CPT1a-Dependent Fatty Acid -Oxidation.

Hepatic ischemia-reperfusion (IR) injury is a clinical issue that can result in poor outcome and lacks effective therapies at present. Mild hypothermia (32-35°C) is a physiotherapy that has been reported to significantly alleviate IR injury, while its protective effects are attributed to multiple mechanisms, one of which may be the regulation of fatty acid -oxidation (FAO). The aim of the present study was to investigate the role and underlying mechanisms of FAO in the protective effects of mild hypothermia.
