Mutations of the KCNJ10 (Kir4.1) K(+) channel underlie autosomal recessive epilepsy, ataxia, sensorineural deafness, and (a salt-wasting) renal tubulopathy (EAST) syndrome. We investigated the localization of KCNJ10 and the homologous KCNJ16 in kidney and the functional consequences of KCNJ10 mutations found in our patients with EAST syndrome. Kcnj10 and(More)
The molecular basis of capacitative (or store-operated) Ca2+ entry is still subject to debate. The transient receptor potential proteins have been hypothesized to be structural components of store-operated Ca2+ channels and recent evidence suggests that Trp3 and its closely related homolog Trp6 are gated by the N-terminal region of the inositol(More)
Von Oktober 1994 bis Juli 1996 nahmen 128 Patienten (30 Frauen und 98 Männer) an einem ambulanten, kardialen Rehabilitationsmodell (Phase II) teil. Ziel dieses Modells war es, die Beeinflussung der wesentlichen Risikofaktoren sowie die Zunahme der Belastbarkeit unmittelbar durch die Rehabilitationsmaßnahme als Primärergebnis und Langzeiteffekt 6 Monate (n =(More)
Mutations in the K+ channel gene KCNJ10 (Kir4.1) cause the autosomal recessive EAST syndrome which is characterized by epilepsy, ataxia, sensorineural deafness, and a salt-wasting tubulopathy. The renal salt-wasting pathology of EAST syndrome is caused by transport defects in the distal convoluted tubule where KCNJ10 plays a pivotal role as a basolateral K+(More)
7013 Background: In two Phase III trials (INTACT 1 & 2), gefitinib ('Iressa', ZD1839) in combination with first-line platinum-based chemotherapy regimens failed to show benefit in terms of survival when compared with chemotherapy alone in patients (pts) with NSCLC. The primary objective of this analysis was to evaluate if EGFR staining was predictive of(More)
More than 50% of mammalian genomes consist of retrotransposon sequences. Silencing of retrotransposons by heterochromatin is essential to ensure genomic stability and transcriptional integrity. Here, we identified a short sequence element in intracisternal A particle (IAP) retrotransposons that is sufficient to trigger heterochromatin formation. We used(More)
Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of Kaposi's sarcoma(1), a highly vascularized tumor originating from lymphatic endothelial cells, and of at least two different B cell malignancies(2,3). A dimeric complex formed by the envelope glycoproteins H and L (gH-gL) is required for entry of herpesviruses into host cells(4). We(More)
The neutral endopeptidase (NEP) is important for calcitonin gene related peptide (CGRP) degradation, while the role of angiotensin converting enzyme (ACE) remains unclear. By using dermal microdialysis we explored the effect of phosphoramidon (NEP blocker), captopril (ACE blocker) and a mixture of both drugs on the intensity of electrically-induced(More)
The present study evaluated the effects of physical exercise on heart rate variability (HRV) in cancer patients. 3 matched groups of each 15 tumour patients (60.4±8.9 years, 27 male, 18 female) were recruited: Physical exercise group 1 (acute treatment), Physical exercise group 2 (post treatment) and non-intervention group (acute treatment, no exercise).(More)
Pre- and postconditioning depend on the activation of adenosine receptors (ARs) at the end of the index ischemia. The aim of this study was to determine which receptor subtypes must be activated. In situ mouse hearts underwent 30 min of regional ischemia, followed by 2 h of reperfusion. As expected, either ischemic postconditioning (6 cycles of 10 s of(More)
