They are clinically and histologically subdivided into seminomas and non-seminomas. 1,25-Dihydroxyvitamin,25(OH)(2)D(3)) is the active form of vitamin D and exerts its actions via a specific intracellular vitamin D receptor (VDR). Several investigations in the recent years have revealed, in addition to a physiological occurrence of the VDR in various tissues, VDR expression in different human malignancies. Furthermore, 1,25(OH)(2)D(3) plays an important role in the regulation of cell proliferation and differentiation. In different normal and malignant cell types, antiproliferative and pro-differentiating effects of 1,25(OH)(2)D(3) are described. We investigated whether TGCT express the VDR, wether differences exist between the histological subtypes and if vitamin D has a function on the proliferation of tumour cells. Furthermore, we investigated the potential function of the vitamin D-regulated genes nuclear receptor co-repressor 1 (NCOR1), nuclear receptor co-repressor 2 (NCOR2), thyroid receptor interacting protein 15 (TRIP I 5), Growth Arrest and DNA Damage (GADD45), MAP kinase-activated protein kinase 2 (MAPKAPK2), Cytochmme P450, family 24, subfamily A, polypeptide 1 (C.YP24A1) and Cytochrome P450, family 27, subfamily B. polypeptide (CYP27B1) in the pathogenesis of TGCT. We demonstrate, for the first time, that primary TGCT as well as TGCT cell lines, express VDR mRNA and protein. Vitamin D and VDR may play a role in the pathogenesis of TGCTs. Furthermore, vitamin D inhibits proliferation of TGCT cell-lines, potentially via an increase in expression of GADD45. Our data suggest that vitamin D could play a role in antitumour therapy."],["dc.identifier.isi","000298780700017"],["dc.identifier.pmid","22213325"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/27850"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Int Inst Anticancer Research"],["dc.relation.issn","0250-7005"],["dc.title","Expression and Function of the Vitamin D Receptor in Malignant Germ Cell Tumour of the Testis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

We reported previously that two prototype members of the mitogen-activated protein kinase (MAPK) family, the MAPK ERK kinase (MEK) and extracellular signal-regulated kinase (ERK), are inactive in malignant testicular germ cells and become active after drug stimulation, leading to apoptosis of tumour cells. In this study, we asked whether the protein phosphatase PP2A, a known inhibitor of the MEK-ERK pathway, participates in the proliferation and/or apoptosis of primary TGCT (n = 48) as well as two TGCT cell lines (NTERA and NCCIT). Quantitative RT-PCR, immunohistochemistry, western blot analyses and phosphatase assay indicate that primary TGCT as well as TGCT cell lines express PP2A and that PP2A is active in TGCT cell lines. The inhibition of PP2A by application of two PP2A inhibitors, cantharidic acid (CA) and okadaic acid (OA), results in a significant increase in caspase-3-mediated apoptosis of TGCT cell lines. Thereby, PP2A inhibition was accompanied by phosphorylation and activation of MEK and ERK. Functional assays using the MEK inhibitor PD98059 demonstrated that the phosphorylation of NIEK and ERK was required for the induction of caspase-3-mediated apoptosis of malignant germ cells. Thus, our data suggest that inhibition of PP2A mediates its apoptosis-inducing effect on TGCT through activation of the MEK-ERK signalling pathway that leads to caspase-3-mediated apoptosis of tumour cells. In addition our results support previous observations that PP2A exerts an anti-apoptotic effect on malignant tumour cells. Copyright (c) 2007 Pathological Society of Great Britain and Ireland.

In the present study, the differentiation of macrophages in renal cell carcinomas was investigated with special regard to their possible role ill tumor growth and spread. Methods: Macrophages were characterized by means of immunohistochemistry of the Ki-M1P, 25F9, MRP8, MRP14, and MRP8/14 antigens and by means of in situ hybridization of CSF-1, its c-fins-coded corresponding receptor, and human monocytic serine esterase-1 (HMSE-1) mRNA. Macrophage subgroups were quantified within central tumor tissue, the corresponding turner host interface, and tumor-free tissue and correlated with tumor necrosis, fibrosis, and tumor stage and grade. Results: Macrophage density was much higher within tumor tissue and the tumor/host interface than in tumor-free tissue. Well-differentiated carcinomas showed a lower degree of macrophage density than less-differentiated carcinomas. Tumor-associated macrophages could be divided into an active inflammatory typo (MR14(+), MRP8/14(+)) and into a late-phase inflammatory type (25F9(+), MRP8(+)). Necrosis was seen in less-differentiated carcinomas and associated with a significantly increased density of MRP14(+) macrophages, which, however, did not correlate with the extent of necrosis. The density of 25F9(+) macrophages was correlated with an extensive connective tissue formation and an advanced tumor stage. c-fms, CSF-I, and HMSE-1 mRNA expression did not discriminate between the macrophage subgroups. Conclusions: Tumor-associated macrophages of the late-stage inflammatory type potentially support the spread of renal cell cancer. CSF-1 derived from tumor cells and macrophages acts as a monocyte attractant and induces macrophage differentiation able to modulate the extracellular matrix rather than to exert cytotoxicity.

Methods: Different myeloid and plasmacytoid DC subsets were characterised by immunohistochemistry. Expression of the so-called \"lymphoid' chemokines CCL19, CCL20, and CCL21 was determined by real time reverse transcription-polymerase chain reaction in Crohn's disease and normal controls. Furthermore, expression of CCL19, CCL20, and CCL21 as well as their receptors CCR6 (for CCL20) and CCR7 (for CCL19 and CCL21) was characterised by immunohistochemistry and, in addition, their cellular localisation was determined by double immunofluorescence investigations. Results: Colonic tissue affected by Crohn's disease was characterised by an increased number of mature myeloid DC forming clusters with proliferating T cells. In keeping with their advanced maturation, DC possess the chemokine receptor CCR7. Increased expression of the CCR7 ligands CCL19 by DC themselves as well as CCL21 by reticular cells and lymphatic vessels was observed in Crohn's disease, thereby causing the matured DC to be trapped at the site of inflammation. Conclusion: Our results demonstrate that autocrine and paracrine actions of lymphoid chemokines in Crohn's disease may lead to increased numbers of mature DC away from their usual migration to lymphoid organs and result in the development of a tertiary lymphatic tissue within the bowel wall maintaining the autoimmune inflammation in Crohn's disease."],["dc.identifier.doi","10.1136/gut.2004.063008"],["dc.identifier.isi","000234553500019"],["dc.identifier.pmid","16118351"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42291"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","B M J Publishing Group"],["dc.relation.issn","0017-5749"],["dc.title","Increased number of mature dendritic cells in Crohn's disease: evidence for a chemokine mediated retention mechanism"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Whereas in 1970s, the survival rate in patients with metastatic testicular tumours was only 5%, these days, 80% of the patients treated by modern chemotherapy will survive their disease. The drug that revolutionised the cure rate for patients with metastatic testicular tumours was cisdiamminedichloroplatinum ( cisplatin, CDDP). In vitro experiments on neoplastic germ cell lines showed that their exquisite sensitivity to CDDP could be attributed to p53-dependent and -independent pathways. Applying cDNA macroarray, semiquantitative RT-PCR and Western blot analyses, blocking experiments, caspase activity assays, and morphological methods, we sought here to define the p53-independent pathway(s) involved in the CDDP-induced apoptosis. For this purpose, we used the human TGCT cell line NCCIT, the mutated p53 of which is known to remain inactive during the course of CDDP-induced apoptosis. Our experiments showed that within hours of CDDP application, two prototype members of the 'mitogen-activated protein kinase' ( MAPK) family, designated 'MAPK ERK kinase' (MEK) and 'extracellular signal-regulated kinase' ( ERK), were dually phosphorylated and caspase-3 became active. Functional assays using MEK inhibitors demonstrated that the phosphorylation of MEK and ERK was required for the activation of caspase-3 as the executing caspase. Interestingly, experiments with the human malignant germ cell line NTERA, which is known to possess wild-type p53, revealed the same results.
