We identified several promoters responsible for the expression of regA, which encodes a global virulence regulator in Citrobacter rodentium. Expression of some of the promoters was strongly autoactivated by RegA in conjunction with bicarbonate. Biochemical and mutational analyses were used to determine the consensus sequence of the RegA-binding sites.

    Eur J Cancer 38(18):2416-20 (2002) PMID 12460786

    The primary aim of this phase II trial was to assess the antitumour activity of ZD0473 in ovarian cancer patients who had failed initial platinum-based therapy. Patients (n=94) were classified as either platinum-sensitive (n=35) or platinum-resistant (n=59) depending on whether they had relapsed or...

    A multicentre, randomised study was carried out in Europe, South Africa and North America to compare the activity and tolerability of oral versus intravenous (i.v.) topotecan in patients with relapsed epithelial ovarian cancer. Patients who had failed first-line therapy after one platinum-based regi...

    The study of the pharmacokinetics and pharmacodynamics of platinum based anti-cancer drugs has done much to direct their development, at both preclinical and clinical levels. The clinical development of cisplatin depended on an understanding of its mechanism of action. The amelioration of the renal...
