Clinical studies have shown that HER-2/Neu is over-expressed in up to one-third of patients with a variety of cancers, including B-cell acute lymphoblastic leukemia (B-ALL), breast cancer and lung cancer, and that these patients are frequently resistant to conventional chemo-therapies. Additionally, in most patients with multiple myeloma, the malignant(More)
Lipoxygenase metabolites of arachidonic acid can act as growth promoting factors for various cancer cell lines. Here we demonstrate that the 5-lipoxygenase inhibitor nordihydroguaiaretic acid potently inhibits anchorage-independent growth of human pancreatic and cervical cancer cells in soft agar and delays growth of pancreatic and cervical tumours(More)
BACKGROUND Our aim was to compare and evaluate apoptosis formation as detected by propidium-iodide (PI)/annexin-V or PI/fluorescein-diacetate (FDA) as dose-response parameters in a human promyelocytic leukemia cell line, HL60. METHODS In exponentially growing HL60 cells, apoptosis was induced by ionizing radiation, hyperthermia, topotecan, and cytosine(More)
“On-demand” regulation of gene expression is a powerful tool to elucidate the functions of proteins and biologically-active RNAs. We describe here three different approaches to the regulation of expression or activity of genes or proteins. Promoter-based regulation of gene expression was among the most rapidly developing techniques in the 1980s and 1990s.(More)
Caspases are key effectors of the apoptotic process. Some of them play important roles in the immune system, being involved in the proteolytic maturation of the key cytokines, including interleukin 1beta (IL-1beta) and IL-18. The latter directs the production of interferon gamma (IFN-gamma). Among pathogens, particularly viruses express various modulators(More)
Glioblastoma multiforme, a highly aggressive tumor of the central nervous system, has a dismal prognosis that is due in part to its resistance to radio- and chemotherapy. The protein kinase C (PKC) family of serine threonine kinases has been implicated in the formation and proliferation of glioblastoma multiforme. Members of the protein kinase D (PKD)(More)
The effects of combined renovascular hypertension and diabetes mellitus on the rat heart were investigated in order to detect possible synergistic effects of the two conditions. Hypertensive diabetic and hypertensive nondiabetic young male Wistar rats were compared with diabetic and nondiabetic controls. Since the normal body weight increase of the diabetic(More)
Postamputationsschmerzen sind eine Herausforderung für den Arzt und beeinträchtigen die Lebensqualität der Patienten erheblich. Eine prospektive, 12-wöchige, nichtinterventionelle Studie aus Deutschland hat die Wirksamkeit und Verträglichkeit des 8 %igen Capsaicin-Pflasters bei Patienten mit peripheren, neuropathischen Schmerzen unter den Bedingungen des(More)
Radioresistance markedly impairs the efficacy of tumor radiotherapy and may involve antiapoptotic signal transduction pathways that prevent radiation-induced cell death. A common cellular response to genotoxic stress induced by radiation is the activation of the nuclear factor kappa B (NF-kappaB). NF-kappaB activation in turn can lead to an inhibition of(More)
