Abstract:
Polychlorované dibenzo-p-dioxiny (PCDD) včetně 2,3,7,8-tetrachlorodibenzo-p-dioxinu (TCDD), polychlorované dibenzofurany (PCDF) a polychlorované bifenyly (PCB) představují skupinu persistentních sloučenin v životním prostředí a jsou to nejvíce toxické polyaromatické uhlovodíky. Biologické a toxické efekty těchto sloučenin jsou zprostředkovány přes receptor pro aromatické uhlovodíky (AhR), což je ligandem …moreAbstract:
AhR-depnedentní proliferaci kontaktně inhibovaných WB-F344 buněk. Relativní potence koplanárních PCB podobných dioxinům (DL-PCBs) a dalších sloučenin podobných dioxinům, které aktivují AhR a způsobují AhR-závislé toxické účinky, jsou základní pro posouzení rizik. Studie sledující závislost dávka vs. odpověď byla provedena v krysí jaterní progenitorové linii WB-F344 za použití několik AhR cílových …moreAbstract:
Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) constitute a group of persistent environmental chemicals, with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) being the most toxic of polyhalogenated aromatic hydrocarbons. Biological and toxic effects of these compounds are mediated through the aryl hydrocarbon receptor (AhR), a ligand …moreAbstract:
rogenitor WB-F344 cells, using several AhR-target genes as the specific end-points of the AhR activation. Due to the fact, that AhR activation and AhR-dependent toxicity might be cell-, tissue- and species-specific, our data were compared with series of other human and rodent in vitro models and consensus toxicity factors (CTFs) were evaluated by QSAR techniques. We evaluated also potential suppressive …more
