Abstract
Genetic manipulation of animal models is a fundamental research tool in biology and medicine but is challenging in large animals. In rodents, models can be readily developed by knocking out genes in embryonic stem cells or by knocking down genes through in vivo delivery of nucleic acids. Swine are a preferred animal model for studying the cardiovascular and immune systems, but there are limited strategies for genetic manipulation. Lipid nanoparticles (LNPs) efficiently deliver small interfering RNA (siRNA) to knock down circulating proteins, but swine are sensitive to LNP-induced complement activation-related pseudoallergy (CARPA). We hypothesized that appropriately administering optimized siRNA-LNPs could knock down circulating levels of plasminogen, a blood protein synthesized in the liver. siRNA-LNPs against plasminogen (siPLG) reduced plasma plasminogen protein and hepatic plasminogen mRNA levels to below 5% of baseline values. Functional assays showed that reducing plasminogen levels modulated systemic blood coagulation. Clinical signs of CARPA were not observed, and occasional mild and transient hepatotoxicity was present in siPLG-treated animals at 5 h post-infusion, which returned to baseline by 7 days. These findings advance siRNA-LNPs in swine models, enabling genetic engineering of blood and hepatic proteins, which can likely expand to proteins in other tissues in the future.

Inflammatory setting, therapeutic strategies targeting some pro-inflammatory cytokines and pathways in mitigating ischemia/reperfusion-induced hepatic injury: a comprehensive review. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024:10.1007/s00210-024-03074-y. [PMID: 38643452 DOI: 10.1007/s00210-024-03074-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 03/28/2024] [Indexed: 04/22/2024]
Abstract
Ischemia/reperfusion injury (IRI) is a key determining agent in the pathophysiology of clinical organ dysfunction. It is characterized by an aseptic local inflammatory reaction due to a decrease in blood supply, hence deprivation of dependent oxygen and nutrients. In instances of liver transplantation, this injury may have irreversible implications, resulting in eventual organ rejection. The deterioration associated with IRI is affected by the hepatic health status and various factors such as alterations in metabolism, oxidative stress, and pro-inflammatory cytokines. The primary cause of inflammation is the initial immune response of pro-inflammatory cytokines, while Kupffer cells (KFCs) and neutrophil-produced chemokines also play a significant role. Upon reperfusion, the activation of inflammatory responses can elicit further cellular damage and organ dysfunction. This review discusses the interplay between chemokines, pro-inflammatory cytokines, and other inflammatory mediators that contribute to the damage to hepatocytes and liver failure in rats following IR. Furthermore, it delves into the impact of anti-inflammatory therapies in safeguarding against liver failure and hepatocellular damage in rats following IR. This review investigates the correlation between cytokine factors and liver dysfunction via examining databases, such as PubMed, Google Scholar, Science Direct, Egyptian Knowledge Bank (EKB), and Research Gate.

Abstract
Background Anesthesia and surgery may deteriorate liver function in patients with elevated liver enzyme levels; therefore, in these patients, choosing anesthetics with less hepatotoxicity is important. Methods This retrospective study investigated the effect of total intravenous anesthesia (TIVA) versus inhalation anesthesia (INHA) on the postoperative liver function in patients with preoperatively elevated liver enzyme levels (aspartate transaminase [AST] or alanine transaminase [ALT] >40 U/L) who underwent non-hepatic surgery under general anesthesia. We compared the changes in enzyme levels within 24 hrs before and after surgery. Results In 730 patients (TIVA: n=138; INHA: n=592), the baseline characteristics were comparable, except for higher comorbidity rates in the TIVA group. The median anesthesia and operation times were significantly longer in the TIVA group because approximately 50% of the TIVA group (vs 19.7% of the INHA group) underwent neurosurgery, which had a relatively longer operation time than other surgeries. Intraoperative hypotensive events and vasopressor use were more frequent in the TIVA group. After 1:4 propensity score matching (TIVA: n=94; INHA: n=376), the baseline characteristics and surgical variables were comparable, except for longer anesthesia time. Before matching, postoperative AST and ALT changes were significantly lower in the TIVA group than in the INHA group. After matching, only the ALT change was significantly lower after TIVA than after INHA [median (interquartile range), -16.7 (-32 to -4) % vs -12.0 (-28.6-6.5) %, P=0.025]. Conclusion TIVA may be safer for patients with preoperatively elevated liver transaminase levels.

Abstract
BACKGROUND Sevoflurane and isoflurane had been reported to improve ischemia/reperfusion injury (I/R) through amelioration of the inflammatory response. We aimed to explore and compare the molecular mechanisms involved in sevoflurane and isoflurane anesthesia in liver ischemia-reperfusion of rat model. METHODS Forty male Wistar rats were randomly divided into 4 groups: sham group, I/R group, sevoflurane group, and isoflurane group. The liver I/R injury model was established to investigate the effect of sevoflurane and isoflurane anesthesia on liver ischemia/reperfusion. The inflammatory markers and complement C3, C5a, and C6 were detected by enzyme-linked immunosorbent assay. Oxidative stress was detected by measuring the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and nitric oxide (NO). RESULTS Our results showed that sevoflurane anesthesia significantly decreased alanine transaminase, aspartate transaminase, and lactate dehydrogenase levels compared with isoflurane and controls. Sevoflurane inhibited I/R injury induced production of tumor necrosis factor α, interleukin 1, interleukin 6, and intercellular cell adhesion molecule-1 and promoted interleukin 10 production more significantly compared with isoflurane. Reduced MDA and NO and elevated SOD release suggested that oxidative stress was attenuated by sevoflurane and isoflurane anesthesia. Both sevoflurane and isoflurane anesthesia significantly decreased plasma C3 levels compared with the I/R injury group without differences. CONCLUSION Sevoflurane anesthesia produced a more significant inhibitive effect on inflammatory cytokines and oxidative stress in liver I/R injury model than isoflurane, suggesting that sevoflurane is more suitable in surgery.

Abstract
Hepatic ischemia/reperfusion (IR) injury is a critical contraindication of hepatobiliary surgery and results in severe liver damage. It is imperative to identify underlying pathophysiological mechanisms. In the current study, a rat model of liver IR was established to explore the mechanisms of sevoflurane during surgical intervention on IR. The detection of cytokines was performed using ELISA and reverse transcription-quantitative polymerase chain reaction and western blot assays were used to detect mRNA and protein expression levels, respectively. The target protein of microRNA (miR)-9-5p was identified by in vitro luciferase reporter assay. Cell apoptosis was detected by Annexin-V/propidium iodide and TUNEL staining assays. The results demonstrated that sevoflurane exerted protective effect against liver IR. Sevoflurane administration ameliorated a cytokine storm by decreasing serum levels of interleukin (IL)-1 and −6 and tumor necrosis factor (TNF)-α, and improved liver function was determined. IR-induced damage was mediated by an increase in transcription factor p65 expression and activation of the nuclear factor (NF)-κB signaling pathway, which were suppressed by sevoflurane treatment. In situ analysis predicted that NFKB3, encoding for p65, may be targeted by miR-9-5p and the hypothesis was verified by in vitro reporter assays using wild type and mutant sequences of the NFKB3 3′-untranslated region. Furthermore, pretreatment of hepatic tissue with a miR-9-5p mimic inhibited IR-associated injury as suggested by the decrease in the Suzuki score and decreased serum levels of TNF-α, IL-1 and IL-6. The results indicated that sevoflurane protected the liver from IR injury by increasing miR-9-5p expression and miR-9-5p may be a potential treatment target in IR.

Abstract
Background Anesthetic agents and type of surgery may contribute to postoperative hepatic injury. Inhalational anesthetics have been associated with hepatic dysfunction after surgery, however, propofol is expected to have a lower potential for postoperative liver injury. This prospective double-blind randomized clinical study was planned to determine whether postoperative liver function differs after anesthesia with isoflurane and total intravenous anesthesia with propofol in patients undergoing a posterolateral thoracotomy. Methods Eighty-eight patients in American Society of Anesthesiologists physical status 1 or 2, aged 16–60 years, and scheduled for an elective posterolateral thoracotomy, were randomly assigned to an anesthetic protocol: propofol ( n = 44) or isoflurane ( n = 44). Induction of anesthesia was similar in both groups. Serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, total bilirubin, and γ-glutamyltransferase were measured before induction of anesthesia and on the first and third days after either propofol or isoflurane anesthesia. Results Mild changes in postoperative serum levels of liver enzymes were significant within each group but the differences between groups were not significant. Conclusions Propofol and isoflurane anesthesia have a comparable minor effect on liver function after an elective posterolateral thoracotomy.
