BACKGROUND One of the major problems in the cure of advanced non-small-cell lung cancer (NSCLC) is its lack of response to cytotoxic drug treatment, and the mechanisms underlying this intrinsic drug resistance are unclear. PATIENTS AND METHODS We determined the expression of a newly recognised drug resistance gene, the Multidrug Resistance-associated(More)
In the present study, we determined the frequency and intensity of MRP protein expression by monoclonal antibody immunohistochemistry in a series of 259 resected invasive primary breast carcinomas, and we evaluated MRP immunoreactivity in relation to patient and tumour characteristics, relapse-free (RFS) and overall survival (OS). The immunostaining was(More)
The expression of the multidrug resistance-associated protein (MRP), a new glycoprotein involved in drug resistance, was investigated in tumour samples from 80 patients with chronic B-cell malignancies by a quantitative RNase protection assay. In B-cell chronic lymphocytic leukaemia (B-CLL) (n = 32), either treated (n = 18) or untreated (n = 14), a high(More)
We determined the expression of the multidrug resistance-associated protein (MRP), a new putative transmembrane drug transporter, in peripheral blood cells from healthy volunteers as well as from 60 patients with acute or chronic leukemia, using an RNase protection assay. MRP appeared to be ubiquitously expressed at low levels in all nonmalignant(More)
One of the major problems in the treatment of squamous cell carcinoma of the oesophagus (ESCC) is the unresponsiveness to cytotoxic drugs. So far, the mechanisms underlying the intrinsic drug resistance of ESCC remain unclear. The aim of this study was to determine the role of the newly recognised drug resistance protein, the multidrug resistance protein(More)
We determined the expression of a newly recognized drug resistance gene, the multidrug resistance-associated protein (MRP) gene, [Cole et al., Science (Washington DC), 258: 1650-1654, 1992], in normal human tissues and in >370 human tumor biopsies using a quantitative RNase protection assay and immunohistochemistry. MRP mRNA appeared to be ubiquitously(More)
The induction of apoptosis by diverse apoptotic stimuli was studied in a panel of 6 testicular germ cell tumour (TGCT) cell lines with defined p53 status. Although the sensitivity to a particular stimulus varied considerably among the TGCT cell lines, the differences in response were not associated with the presence of functional p53. Mutant (mt)(More)
This study presents data for verification of the iPlan RT Monte Carlo (MC) dose algorithm (BrainLAB, Feldkirchen, Germany). MC calculations were compared with pencil beam (PB) calculations and verification measurements in phantoms with lung-equivalent material, air cavities or bone-equivalent material to mimic head and neck and thorax and in an Alderson(More)
An overview of the development of anti-tumor organotin derivatives in selected classes of compounds is presented and discussed. High to very high in vitro activity has been found, sometimes equaling that of doxorubicin. Solubility in water is an important issue, dominating the in vivo testing of compounds with promising in vitro properties. The cytotoxicity(More)
SAFETYNET is a European Thematic Network on Process Safety funded under the Brite-Euram Programme. The aim of this network is to reduce the time delay between research results and their practical use in industry in order to stimulate further development and adoption of technologies in the field of process safety. This is mainly done in areas related both to(More)
