Project description:Acetaminophen (APAP) overdose can lead to acute kidney injury (AKI), yet its molecular mechanisms remain unclear and no effective treatments are currently available. In this study, we combined transcriptomic, proteomic, and phosphoproteomic profiling of kidneys from APAP-exposed mice to explore molecular mechanisms and potential therapeutic strategies. Ten-week-old male C57BL/6 mice were fasted overnight for 16 hours prior to APAP treatment. Acute kidney injury was induced by intraperitoneal injection of APAP overdose (300 mg/kg body weight) for 6 hours (n = 4). Control mice received an equivalent volume of PBS via intraperitoneal injection (n = 4). Kidney tissues were subsequently collected from APAP-induced kidney injury mice and PBS-injected controls.

Project description:Acetaminophen (APAP) overdose can cause acute kidney injury (AKI), but its molecular mechanisms remain poorly understood and no effective treatments are currently available. In this study, we performed an integrated analysis combining transcriptomic, proteomic, and phosphoproteomic profiling of kidney tissues from APAP-treated mice to investigate the underlying molecular mechanisms and identify potential therapeutic targets. Ten-week-old male C57BL/6 mice were fasted overnight for 16 hours prior to APAP administration. AKI was induced by intraperitoneal injection of a high dose of APAP (300 mg/kg body weight) for 6 hours (n = 4), while control mice received an equivalent volume of PBS via intraperitoneal injection (n = 4). Kidney tissues were collected from both APAP-treated and control groups for downstream omics analyses.

Project description:Overdose of acetaminophen (APAP) is the major cause of acute liver failure in the Western world with very limited treatment options. Previous studies from our groups and others have shown that timely activation of liver regeneration is a critical determinant of transplant-free survival of APAP-induced acute liver failure (ALF) patients. We used affy microarrays to explore the mechanisms of transcriptional expression in YAP-KO mice after 300mg/kg APAP overdose.

Project description:Acetaminophen (APAP) is the most widely used analgesic in the United States. Its acute overdose causes liver damage by inducing localized centrilobular cell death. Because of widespread use, APAP toxicity has become the most frequent cause of acute liver failure. Many factors have been associated with the susceptibility of APAP-induced liver injuries, however, few of them have been confirmed and used in the clinical setting. We tried to identify the subset of factors that could affect susceptibility to APAP-induced liver injury by an integrative genetic, transcriptional and 2-D-NMR-based metabolomic analysis across a panel of inbred mouse strains.

Project description:There is a paucity of data on how protease-activated receptors (PARs) regulate transcriptional reprogramming. We sought to determine how the expression of two members of the PAR family (PAR1 and PAR4) on hepatic endothelial cells (ECs) influence transcription in the liver after acetaminophen (APAP) overdose. We combined EC-specific translating ribosome affinity purification with next-generation sequencing (EC-TRAPseq) in endothelial-specific Par1 and Par4 knockout mice. This allowed us to gain an in vivo snapshot of how EC gene expression profiles change with APAP overdose and how the loss of endothelial PARs impacts transcriptional reprogramming in hepatic ECs. This approach also provided a high degree of sensitivity for detecting low-expressing transcripts. We found distinct transcriptional changes in APAP-overdosed ECs between endothelial Par1 and Par4 knockout mice.

Experiment Overall Design: After a single administration of high dose (300 mg/kg i.p.) APAP, liver and blood samples were extracted from 3 sensitive (C57B6, DBA/2, and SmJ) and 1 resistant (SJL) mice strains at 0, 3 and 6 hour after APAP exposure. Endogenous metabolites from liver samples were analyzed by 1H-13C 2-dimensional-NMR and gene expression changes occurring within these liver samples were simultaneously analyzed using Affymetrix microarrays. The transcriptional and metabolomic data was jointly analyzed, and functional information within the Gene Ontology database was used to identify the subset of genes that could affect susceptibility to APAP-induced liver injury in the early phase response.

Project description:Acetaminophen (APAP) overdose provokes various degrees of liver injury, whose pathogenesis involves multiple pathological events, such as mitochondrial damage and necrosis. E3 ubiquitin ligase neural precursor cell expressed developmentally downregulated 4-1 (NEDD4-1) plays vital roles in regulating a wide spectrum of physiological processes, and has been implicated in the pathogenesis of numerous liver disease. However, studies about the regulation of NEDD4-1 on APAP-induced liver injury (AILI) is still deficient. Thus, the aim of this study is to determine whether and how NEDD4-1 plays a role in AILI. Thus, we performed transcriptomic studies comparing liver samples of APAP-treated Flox or APAP-treated hepatocyte-specific Nedd4-1 (HepKO) deficiency mice,

Project description:Sluka2016 - Acetaminophen metabolism
Liver metabolism of Acetaminophen: Acetaminophen (APAP) is
metabolized in the liver in both Phase I and Phase II reactions.
Phase II reactions convert APAP to APAP-glucuronide and
APAP-sulfate. Phase I reactions involve Cytochrome P450 mediated
(mostly Cyp450-2E1 and -1A2) conversion of APAP to
N-acetyle-p-quinoneimine (NAPQI), which goes on to react with
cellular nucleophiles such as glutathione (GSH). At high doses of
APAP significant GSH depletion in hepatocyte occurs resulting in
cell necrosis and and in extreme cases death.

Abstract:
We describe a multi-scale, liver-centric in silico modeling
framework for acetaminophen pharmacology and metabolism. We
focus on a computational model to characterize whole body
uptake and clearance, liver transport and phase I and phase II
metabolism. We do this by incorporating sub-models that span
three scales; Physiologically Based Pharmacokinetic (PBPK)
modeling of acetaminophen uptake and distribution at the whole
body level, cell and blood flow modeling at the tissue/organ
level and metabolism at the sub-cellular level. We have used
standard modeling modalities at each of the three scales. In
particular, we have used the Systems Biology Markup Language
(SBML) to create both the whole-body and sub-cellular scales.
Our modeling approach allows us to run the individual
sub-models separately and allows us to easily exchange models
at a particular scale without the need to extensively rework
the sub-models at other scales. In addition, the use of SBML
greatly facilitates the inclusion of biological annotations
directly in the model code. The model was calibrated using
human in vivo data for acetaminophen and its sulfate and
glucuronate metabolites. We then carried out extensive
parameter sensitivity studies including the pairwise
interaction of parameters. We also simulated population
variation of exposure and sensitivity to acetaminophen. Our
modeling framework can be extended to the prediction of liver
toxicity following acetaminophen overdose, or used as a general
purpose pharmacokinetic model for xenobiotics.

Project description:Acetaminophen (APAP) is the major cause of drug-induced liver injury, with limited treatment options. APAP overdose invokes excessive oxidative stress that triggers mitochondria-to-nucleus retrograde pathways, contributing to APAP-induced liver injury (AILI). Mesenchymal stem cell therapy is a promising tool for acute liver failure. Therefore, the purpose of this study is to investigate the beneficial effects of adipose-derived mesenchymal stem cell (AMSC) therapy on AILI and reveal the potential therapeutic mechanisms. C57BL/6 mice are used as the animal model and AML12 normal murine hepatocytes as the cellular model of APAP overdose. Immunohistochemical staining, western blotting, immunofluorescence staining, and RNA sequencing assay are used for assessing the efficacy and validating mechanisms of AMSC therapy. We found AMSC therapy effectively ameliorated AILI, while delayed AMSC injection lost its efficacy related to the c-Jun N-terminal kinase (JNK)-mediated mitochondrial retrograde pathways. We further found that AMSC therapy inhibited JNK activation and mitochondrial translocation, reducing APAP-induced mitochondrial damage. The down-regulation of activated Ataxia telangiectasia mutated (ATM) and DNA damage response proteins in AMSC treated mice liver indicated AMSC blocked the JNK-ATM pathway. Overall, AMSC may be an effective treatment for AILI by inhibiting JNK-ATM mitochondrial retrograde pathway, which improves APAP-induced mitochondrial dysfunction and liver injury.
