We have previously shown that iron regulates the transcription of inducible nitric oxide synthase (iNOS). To elucidate the underlying mechanisms we performed a series of transient transfections of murine fibroblast (NIH-3T3) and macrophage-like cells (J774.A1) with reporter plasmids containing the iNOS promoter and deletions thereof. By means of this and(More)
BACKGROUND S100 A2 and hnRNP A2/B1 (heterogeneous ribonucleoprotein A2/B1) with its splicing variant hnRNP B1 are proteins which are involved in cellular proliferation, differentiation and protein synthesis and are up-regulated in non-small cell lung cancer (NSCLC). Since previous studies using paraffin-embedded tissues indicated a high potential of these(More)
Mesial temporal lobe epilepsy (TLE) is associated with pronounced anatomical and biochemical changes in the hippocampal formation including extensive neurodegeneration, reorganization of mossy fibres and sprouting of interneurons. Although the anatomical features and some of the physiological consequences of hippocampal remodeling have been well documented,(More)
IL-13 is a cytokine produced by T lymphocytes, mast cells, basophils, and certain B cell lines that up-regulates or inhibits various macrophage functions. In the present study we analyzed the mechanisms of suppression of nitric oxide (NO) release by IL-13 in the macrophage cell line J774A.1 and in thioglycolate-elicited mouse peritoneal macrophages. In both(More)
The ribosomal protein MvaS7 from the methanogenic archaeon Methanococcus vannielii is a protein of 188 amino acids, i.e., it is 42 amino acids longer than previously suggested. The triplet TTG serves as a start codon. The methanogenic translation initiation region that includes the rare TTG start codon is recognized in Escherichia coli.
Bone marrow-derived endothelial progenitor cells (EPC) play an important role in neovascularisation and tumor growth. However, the clinical relevance of EPCs on blood vessel formation in non-small cell lung cancer (NSCLC) is unclear. EPC numbers in circulation are very low and therefore their detection is technically challenging. In the present study, 10(More)
A real-time PCR technique with automated computerized analysis (TaqMan ) was tested to detect K-ras mutations in 66 patients suffering from NSCLC. This technology is characterized by high reproducibility of data and a time-saving analysis procedure. In 11% (7/66) of the tumour specimens and 2% (1/58) of adjacent tumour-free lung specimens a K-ras codon 12(More)
BACKGROUND Patients suffering from advanced gastric cancer still have a poor prognosis and treatment options are limited. In our previous phase II trial (AGMT-Gastric-1), we showed that the combination of oxaliplatin and irinotecan was well tolerated and effective. The same chemotherapy regimen was now tested in combination with cetuximab in a multicenter(More)
