The ATP-binding cassette transporter ABCG2 plays a prominent role in cardiovascular and cancer pathophysiology, is involved in the pathogenesis of gout, and affects pharmacokinetics of numerous drugs. Telmisartan, a widely used AT1 receptor antagonist, inhibits the transport capacity of ABCG2 and may cause drug-drug interactions, especially in individuals(More)
In the present study we investigated the influence of intron I of the rat renin gene on the transcriptional activity of its promoter in cell culture. The presence of intron I abolished the transcription of reporter genes (luciferase and lacZ) in the non-renin-expressing human embryonic kidney cell line 293, while it did not significantly affect the activity(More)
Isoprostanes are free radical-catalysed PG-like products of unsaturated fatty acids, such as arachidonic acid, which are widely recognized as reliable markers of systemic lipid peroxidation and oxidative stress in vivo. Moreover, activation of enzymes, such as COX-2, may contribute to isoprostane formation. Indeed, formation of isoprostanes is considerably(More)
The impact of the gout-causing C421A (Q141K) single nucleotide polymorphism (SNP) on ABC transporter ABCG2 expression and function has been extensively characterized. However, the influence of the C421A SNP on 3'-UTR-dependent ABCG2 regulation has not been analysed so far. To elucidate this matter, we generated vectors for expression of either the ABCG2(More)
