The 3p21.3 tumour suppressor gene (TSG) RASSF1A is inactivated predominantly by promoter methylation and rarely by somatic mutations. Recently we demonstrated that epigenetic inactivation of RASSF1A is frequent in both clear cell and papillary adult renal cell carcinomas (even though 3p21.3 allele loss is rare in papillary tumours). Wilms' tumour is the(More)
To investigate the role of epigenetic gene silencing in the pathogenesis of Wilms' tumour and renal cell carcinoma (RCC), we determined their methylation profile using a candidate gene approach. Thus, 40 Wilms' tumours and up to 49 adult RCC were analysed by methylation-specific PCR for promoter methylation at CASP8, CDH1, CDH13, DAPK, MGMT, NORE1A, p14ARF(More)
The Wilms' tumor suppressor protein WT1 is a transcriptional regulator that plays a key role in the development of the kidneys. The transcriptional activation domain of WT1 is subject to regulation by a suppression region within the N terminus of WT1. Using a functional assay, we provide direct evidence that this requires a transcriptional cosuppressor,(More)
The recombinant form of the extracellular domain of the IL-4 receptor (sIL-4R) is a potential candidate to neutralize IL-4; however, murine sIL-4R displayed both antagonistic and agonistic activity in vivo. Here we show that human recombinant sIL-4R induced the formation of complexed IL-4 in supernatants of activated T cells in a dose-dependent manner as(More)
Elevated levels of immunoglobulin (Ig) E are associated with bronchial asthma, a disease characterized by eosinophilic inflammation of the airways. Activation of antigen-specific T helper (Th) 2 cells in the lung with the subsequent release of interleukin (IL) 4 and IL-5 is believed to play an important role in the pathogenesis of this disease. In this(More)
AIMS Conventional approaches to the management of neuropathic pain (NeP) often yield unsatisfactory results. We aimed to investigate pregabalin, a gamma-aminobutyric acid (GABA)-analogue, in a wide range of pregabalin naive patients with treatment refractory NeP. METHODS Investigator-initiated, 4-week, open, prospective multicentre study in tertiary care.(More)
The presence of cytokine producing cells is most easily revealed by techniques measuring the secreted cytokines in culture supernatants or body fluids. However, these techniques only measure the bulk cytokine release by a given, often mixed cell population. To demonstrate cytokine production at the single cell level, immunocytochemistry (ICC) and in situ(More)
The production of interleukin 2 (IL 2), IL 4 and interferon-gamma (IFN-gamma) by in vitro activated unselected human blood mononuclear cells was studied at a single-cell level. Individual lymphokine-synthesizing cells were identified by intracellular immunofluorescent staining using cytokine-specific monoclonal or polyclonal antibodies. Cultures from adult(More)
The Wilms' tumour suppressor protein WT1 plays a central role in the development of the kidney and also other organs. WT1 can act as a transcription factor with highly context-specific activator and repressor functions. We previously identified Brain Acid Soluble Protein 1 (BASP1) as a transcriptional cosuppressor that can block the transcriptional(More)
Interleukin (IL)-4 and IL-5 are two cytokines which synergize in the induction of several biological effector functions. They are produced by mouse and human T helper 2 (Th2) and T helper 0 (Th0) cells. Little is known about the regulation of the two cytokines at the single-cell level. Here we show, using a flow cytometric intracellular staining technique,(More)
