Caveolin-1 Alleviates Acetaminophen-Induced Fat Accumulation in Non-Alcoholic Fatty Liver Disease by Enhancing Hepatic Antioxidant Ability via Activating AMPK Pathway
In this study, seven-week-old C57BL/6 male mice (18–20 g) were raised under similar conditions for in vivo experiment. In vitro, L02 cells were treated with A/O (alcohol and oleic acid mixture) for 48 h, and APAP was added at 24 h for further incubation. The results showed that the protein expression of the AMPK/Nrf2 pathway was enhanced after CAV1 upregulation. The effects of CAV1 on fat accumulation, ROS, and the AMPK/Nrf2 anti-oxidative pathway were reduced after the application of CAV1-siRNA. Finally, treatment with compound C (an AMPK inhibitor) prevented CAV1 plasmid-mediated alleviation of oxidative stress and ...

GLT25D2 Is Critical for Inflammatory Immune Response to Promote Acetaminophen-Induced Hepatotoxicity by Autophagy Pathway
In conclusion, our study proves that the upregulated expression of GLT25D2 decreased autophagy contributing to APAP-induced hepatotoxicity by mediating the inflammatory immune regulatory mechanism.

TLR4 promotes liver inflammation by activating the JNK pathway.
CONCLUSIONS: APAP-treated TLR4-/- mice showed milder liver injury compared to WT mice. It was confirmed that TLR4 could activate the JNK signaling pathway to induce the secretion of inflammatory factors and the infiltration of macrophages to promote APAP-induced liver injury. This finding might provide a new prevention and treatment idea for clinical drug-induced hepatitis. PMID: 31539158 [PubMed - in process]

Baicalein and baicalin alleviate acetaminophen-induced liver injury by activating Nrf2 antioxidative pathway: the involvement of ERK1/2 and PKC.
This study investigated the protection of baicalin and its aglycone baicalein against APAP-induced hepatotoxicity and its mechanism. Baicalein and baicalin alleviated APAP-induced hepatotoxicity both in vitro and in vivo. Moreover, baicalin-provided this protection was not diminished in hepatocytes or mice treated with β-glucuronidase inhibitor. Results of liver glutathione (GSH) and reactive oxygen species (ROS) formation demonstrated the alleviation of baicalein and baicalin on APAP-induced liver oxidative stress injury. Baicalein and baicalin induced the activation of nuclear factor erythroid 2-related factor 2 (Nrf2) ...

Salvianolic acid B protects against acetaminophen hepatotoxicity by inducing Nrf2 and phase II detoxification gene expression via activation of the PI3K and PKC signaling pathways
Publication date: Available online 24 December 2014 Source:Journal of Pharmacological Sciences Author(s): Musen Lin , Xiaohan Zhai , Guangzhi Wang , Xiaofeng Tian , Dongyan Gao , Lei Shi , Hang Wu , Qing Fan , Jinyong Peng , Kexin Liu , Jihong Yao Acetaminophen (APAP) is used drugs worldwide for treating pain and fever. However, APAP overdose is the principal cause of acute liver failure in Western countries. Salvianolic acid B (SalB), a major water-soluble compound extracted from Radix Salvia miltiorrhiza, has well-known antioxidant and anti-inflammatory actions. We aimed to evaluate the ability of SalB to protect again...
