Suppression of SIRT1/FXR signaling pathway contributes to oleanolic acid-induced liver injury
In conclusion, our study reveals that SIRT1/FXR pathway is crucial in OA-induced hepatotoxicity. Activation of SIRT1/HNF1α/FXR axis may represent a novel therapeutic target for ameliorating OA and other herb-induced hepatotoxicity.PMID:37028458 | DOI:10.1016/j.taap.2023.116509

Ring finger protein 10 improves pirarubicin-induced cardiac inflammation by regulating the AP-1/Meox2 signaling pathway
Toxicol Appl Pharmacol. 2023 Feb 3:116411. doi: 10.1016/j.taap.2023.116411. Online ahead of print.ABSTRACTOBJECTIVES: Pirarubicin (THP) is widely used in clinical antitumor therapy, but its cardiotoxicity seriously affects the therapeutic effect in patients. In the study, we investigated the role of ring finger protein 10 (RNF10) in cardiotoxicity induced by THP.MATERIALS AND METHODS: A cardiac toxicity model in Sprague-Dawley (SD) rats induced by THP was established. Changes in diet, weight, electrocardiogram (ECG), and echocardiography were observed. Serum levels of brain natriuretic peptide (BNP), creatine kinase MB (CK...

Hexavalent chromium increases the metabolism and genotoxicity of aromatic amine carcinogens 4-aminobiphenyl and β-naphthylamine in immortalized human lung epithelial cells
The objective of the research presented here is to investigate the effects of Cr(VI) on the metabolism and genotoxicity of 4-ABP and BNA in immortalized human lung epithelial cells (BEP2D) expressing NAT1 and NAT2. Exposure to Cr(VI) for 48 h increased NAT1 activity (linear regression analysis: P < 0.0001) as measured by N-acetylation of para-aminobenzoic acid (PABA) in BEP2D cells but not NAT2 N-acetylation of sulfamethazine, which are prototypic NAT1 and NAT2 substrates respectively. Cr(VI) also increased the N-acetylation of 4-ABP and BNA. In BEP2D cells the N-acetylation of 4-ABP (1-3 μM) exhibited a dose-dependent...

Salidroside attenuates myocardial ischemia/reperfusion injury via AMPK-induced suppression of endoplasmic reticulum stress and mitochondrial fission
In this study, we established a myocardial ischemia/reperfusion (I/R) rat model. Rat hearts exposed to Sal with or without compound C were then subjected to I/R. Further, H9c2 cardiomyocytes were subjected to simulated ischemia/reperfusion (SIR) by hypoxia-reoxygenation. The rats and cardiomyocytes were pretreated with Sal, followed by Compound C and AMPK-siRNA to block AMPK activity. We found that Sal significantly ameliorated cardiac function, mitigated infarct size and serum content of lactate dehydrogenase and creatine kinase, improved mitochondrial function, and reduced mitochondrial fission and apoptosis. Furthermore...

Enzyme-sensitive nanoparticles, smart TAT and cetuximab conjugated immunoliposomes to overcome multidrug resistance in breast cancer cells
Toxicol Appl Pharmacol. 2022 Mar 18:115989. doi: 10.1016/j.taap.2022.115989. Online ahead of print.ABSTRACTDue to recent advances in the field of small molecule-based drugs, designing an efficient siRNA delivery system seems essential. Here, modified sets of lipids conjugated with cell-penetrating TAT peptide, MMP2 enzyme-sensitive moiety, and cetuximab antibodies against the EGF receptor were synthesized, purified and verified on HPLC, TLC, SEM, and DLS analyses. Different cellular and molecular experiments were designed to evaluate the transfection efficiency, targeting properties, and functions, including cytotoxicity a...

Cadmium induces placental glucocorticoid barrier damage by suppressing the cAMP/PKA/Sp1 pathway and the protective role of taurine
Toxicol Appl Pharmacol. 2022 Feb 24:115938. doi: 10.1016/j.taap.2022.115938. Online ahead of print.ABSTRACTCadmium (Cd) exposure during pregnancy damages the placental glucocorticoid (GC) barrier, exposes the foetus to excess corticosterone (CORT) levels, and eventually inhibits foetal development. In addition, taurine (Tau) alleviates the toxicity of Cd on liver and kidney, but limited data are available on the role of Tau against the toxicity of heavy metals on female reproduction and fetal development. The present study was conducted to investigate the specific mechanism of Cd-induced placental GC barrier damage and the...

Melatonin alleviates doxorubicin-induced mitochondrial oxidative damage and ferroptosis in cardiomyocytes by regulating YAP expression
In this study, we established a Dox-induced cardiotoxicity model in H9c2 cardiomyocytes, zebrafish, and SD rats to explore the mechanism by which Mel alleviates Dox-induced cardiotoxicity. In vivo and in vitro experiments showed that Dox significantly decreased the viability of H9c2 cells, induced apoptosis, myocardial injury, and effectively up-regulated the expression of p-YAP but down-regulated the expression of YAP. Furthermore, we found that Dox significantly up-regulated the expression of ferroptosis-associated protein ACSL4 and down-regulated expression of GPX4. Interestingly, these effects of Dox were reversed foll...
