Type of study : -
N(Total) : -
N(Treatment) : -
Sex : -
Age : -
Route : -

Dose/Conc.(drug) : -
Result : Negative
Remark : Result: Transfection of CYP2B6-2.2 kb in the absence of exogenous Nuclear receptor (NRs) attest that endogenous Pregnane X receptor (PXR) and Constitutive androstane receptor (CAR) in HepG2 cells only exhibit negligible activation of the reporter compared with the potent response when exogenous PXR or CAR was included.
Note : Abbreviations: AhR = Arylhydrocarbon receptor GA = Ginkgolide A, GB = Ginkgolide B, CAR = Constitutive androstane receptor, BB = Bilobalide, Que = Quercetin, Kae = Kaempferol, Tam = Tamarexetin
