1 Nelfinavir and its active metabolite M8 are partial agonists and competitive antagonists of the human pregnane X receptor. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
2 The present study addresses the effects of nelfinavir and its major and pharmacologically active metabolite nelfinavir hydroxy-tert-butylamide (M8) on PXR to elucidate the underlying molecular mechanism. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
3 Impaired co-activator recruitment by nelfinavir, as compared to the full agonist rifampin, proved to be the underlying mechanism of both effects on PXR. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
4 Physiological relevance of nelfinavir-dependent modulation of PXR activity was investigated in respectively treated primary human hepatocytes, which showed differential induction of PXR target genes and antagonism of rifampin-induced ABCB1 and CYP3A4 gene expression. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
5 Physiological relevance of nelfinavir-dependent modulation of PXR activity was investigated in respectively treated primary human hepatocytes, which showed differential induction of PXR target genes and antagonism of rifampin-induced ABCB1 and CYP3A4 gene expression. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
6 In conclusion, we elucidated here the molecular mechanism of nelfinavir interaction with PXR. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
7 It is hypothesized that modulation of PXR activity may impact on the anticancer effects of nelfinavir. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
8 Nelfinavir anticancer activity may partially rely on modulation of PXR, which itself is discussed as a therapeutic target in cancer therapy and for the reversal of chemoresistance. Nelfinavir nuclear receptor subfamily 1 group I member 2 Homo sapiens
