The molecular requirements for the translocation of secretory proteins across, and the integration of membrane proteins into, the plasma membrane of Escherichia coli were compared. This was achieved in a novel cell-free system from E. coli which, by extensive subfractionation, was simultaneously rendered deficient in SecA/SecB and the signal recognition(More)
An oligodeoxynucleotide-dependent method to generate nascent polypeptide chains was adopted for use in a cell-free translation system prepared from Escherichia coli. In this way, NH2-terminal pOmpA fragments of distinct sizes were synthesized. Because most of these pOmpA fragments could be covalently linked to puromycin, precipitated with(More)
PURPOSE Panobinostat is partly metabolized by CYP3A4 in vitro. This study evaluated the effect of a potent CYP3A inhibitor, ketoconazole, on the pharmacokinetics and safety of panobinostat. METHODS Patients received a single panobinostat oral dose on day 1, followed by 4 days wash-out period. On days 5-9, ketoconazole was administered. On day 8, a single(More)
The endothelin receptor antagonist avosentan may cause fluid overload at doses of 25 and 50 mg, but the actual mechanisms of this effect are unclear. We conducted a placebo-controlled study in 23 healthy subjects to assess the renal effects of avosentan and the dose dependency of these effects. Oral avosentan was administered once daily for 8 days at doses(More)
PURPOSE Panobinostat is a novel oral pan-deacetylase inhibitor with promising anti-cancer activity. The study aimed to determine the influence of food on the oral bioavailability of panobinostat. METHODS This multicenter study consisted of a randomized, three-way crossover, food-effect study period (cycle 1) followed by single-agent panobinostat continual(More)
PURPOSE Panobinostat is a potent oral pan-deacetylase inhibitor with promising clinical activity in hematologic malignancies. Panobinostat was shown to inhibit CYP2D6 activity in vitro; thus understanding the magnitude of the potential clinical inhibition of panobinostat on co-medications that are CYP2D6 substrates becomes important. METHODS This study(More)
We have cloned the secA gene of the alpha-subclass purple bacterium Rhodobacter capsulatus, a close relative to the mitochondrial ancestor, and purified the protein after expression in Escherichia coli. R. capsulatus SecA contains 904 amino acids with 53% identity to E. coli and 54% identity to Caulobacter crescentus SecA. In contrast to the nearly equal(More)
This paper describes the construction and application of a low-cost roller bottle-like culture appliance in which hybridoma cells can be cultivated in high density in dialysis tubing. The appliance facilitates the simultaneous culture of up to four cell lines yielding 50 ml culture volume of each. Samples for follow-up analysis of the cultures can easily be(More)
OBJECTIVE Avosentan is a potent, selective endothelin A receptor blocker. The pharmacokinetics of avosentan were investigated in healthy male and female volunteers, following oral and i.v. administration of single doses of avosentan and its absolute bioavailability was determined. METHODS In a randomized, balanced open-label, three-period oral crossover(More)
OBJECTIVE Avosentan is a potent, selective endothelin A receptor blocker. The effect of food intake on the pharmacokinetics of avosentan was investigated in healthy volunteers. METHODS In a randomized, open-label, 2-period oral crossover study, 12 healthy subjects (8 males and 4 females) received Treatments A and B. Treatment A consisted of a single dose(More)
