The role of hypoxia-inducible factor 1 alpha (HIF-1 α) modulation in heavy metal toxicity
Arch Toxicol. 2023 Mar 18. doi: 10.1007/s00204-023-03483-7. Online ahead of print.ABSTRACTHypoxia-inducible factor 1 (HIF-1) is an oxygen-sensing transcriptional regulator orchestrating a complex of adaptive cellular responses to hypoxia. Several studies have demonstrated that toxic metal exposure may also modulate HIF-1α signal transduction pathway, although the existing data are scarce. Therefore, the present review aims to summarize the existing data on the effects of toxic metals on HIF-1 signaling and the potential underlying mechanisms with a special focus on prooxidant effect of the metals. The particular effect of...

Dose-dependent pleiotropic role of neutrophils during acetaminophen-induced liver injury in male and female mice
Arch Toxicol. 2023 Mar 16. doi: 10.1007/s00204-023-03478-4. Online ahead of print.ABSTRACTAcetaminophen (APAP) overdose is the leading cause of acute liver failure in western countries. APAP can cause extensive hepatocellular necrosis, which triggers an inflammatory response involving neutrophil and monocyte recruitment. Particularly the role of neutrophils in the injury mechanism of APAP hepatotoxicity has been highly controversial. Thus, the objective of the current study was to assess whether a potential contribution of neutrophils was dependent on the APAP dose and the sex of the animals. Male and female C57BL/6 J mice...

Potency ranking of pyrrolizidine alkaloids in metabolically competent human liver cancer cells and primary human hepatocytes using a genotoxicity test battery
In conclusion, our findings strongly support the concept of grouping PAs into potency classes and help to pave the way for a broader acceptance of relative potency factors in risk assessment.PMID:36928417 | DOI:10.1007/s00204-023-03482-8 (Source: Archives of Toxicology)

Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) causes seizure activity in larval zebrafish via antagonism of γ-aminobutyric acid type A receptor α1β2γ2
Arch Toxicol. 2023 Mar 13. doi: 10.1007/s00204-023-03475-7. Online ahead of print.ABSTRACTHexahydro-1,3,5-trinitro-1,3,5-triazine, or Royal Demolition Explosive (RDX), is a major component of plastic explosives such as C-4. Acute exposures from intentional or accidental ingestion are a documented clinical concern, especially among young male U.S. service members in the armed forces. When ingested in large enough quantity, RDX causes tonic-clonic seizures. Previous in silico and in vitro experiments predict that RDX causes seizures by inhibiting α1β2γ2 γ-aminobutyric acid type A (GABAA) receptor-mediated chloride curren...

PBTK modeling of the pyrrolizidine alkaloid retrorsine to predict liver toxicity in mouse and rat
Arch Toxicol. 2023 Mar 11. doi: 10.1007/s00204-023-03453-z. Online ahead of print.ABSTRACTRetrorsine is a hepatotoxic pyrrolizidine alkaloid (PA) found in herbal supplements and medicines, food and livestock feed. Dose-response studies enabling the derivation of a point of departure including a benchmark dose for risk assessment of retrorsine in humans and animals are not available. Addressing this need, a physiologically based toxicokinetic (PBTK) model of retrorsine was developed for mouse and rat. Comprehensive characterization of retrorsine toxicokinetics revealed: both the fraction absorbed from the intestine (78%) an...
