Project description:The well-known difference in sensitivity of mice and rats to acetaminophen (APAP) liver injury has been related to differences in the fraction that is bioactivated to the reactive metabolite N-acetyl-p-benzoquinoneimine (NAPQI). Physiologically-based pharmacokinetic modelling was used to identify doses of APAP (300 and 1000 mg/kg in mice and rats, respectively) yielding similar hepatic burdens of NAPQI, to enable the comparison of temporal liver tissue responses under conditions of equivalent chemical insult.

Project description:Hepatic RNA specimens from mice (C57BL/6) of the 4 groups (vehicle-treated at 24h/48h, n=6; acetaminophen (APAP)-treated (300mg/kg) at 24h/48h, n=7) were pooled at equal shares. Thereafter, pooled RNA underwent analysis by 3'mRNA sequencing (MACE, GenXPro, Frankurt, Germany).
Project description:This study aims to investigate the role of IER2 in acetaminophen (APAP)- induced liver injury. Male C57BL/6J mice were randomized to receive a single tail vein injection of either AAV8-GFP or AAV8-Ier2. Mice were fasted overnight for 14 hours followed by intraperitoneal administration of APAP (500 mg/kg). Animals were sacrificed 8 hours post-APAP challenge, and liver tissues were collected for proteomic profiling. This study aims to characterize the proteomic changes associated with IER2 overexpression during APAP hepatotoxicity, thereby establishing a foundation for subsequent mechanistic investigations.
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.
