Genomic Structure and in Vivo Expression of the Human Organic Anion Transporter 1 (hOAT1) Gene
2000
The human organic anion transporter 1 (hOAT1) plays a key role in the secretion of an array of potentially toxic organic anions including many clinically important drugs. Here we report on the genomic cloning of hOAT1. A human genomic library was used for screening of a PAC (P1 artificial chromosome) clone applying PCR techniques. Sequencing of several restriction subclones and of a PCR-generated clone revealed that the hOAT1 gene spans 8.2 kb and is composed of 10 exons divided by 9 introns. RT-PCR studies in a human kidney specimen led to the detection of two new splice variants, hOAT1-3 and hOAT1-4, showing a 132-bp in-frame deletion. Using fluorescence in situ hybridization (FISH) we ma…
Biological characterization of laryngeal squamous-cell carcinoma
1996
The traditional prognostic factors, including stage of disease and tumour grade, have shown a limited prognostic significance and an inability to predict clinical response to specific treatment in patients with laryngeal squamous-cell carcinoma. More recent data suggest that cell kinetics indices, DNA-ploidy, lysosomal cysteine proteinase expression and genetic changes of both tumour suppressor genes and proto-oncogenes may be considered as reliable and reproducible indicators of biological aggressiveness in these patients. Moreover, the frequency of different genetic alterations suggests that several pathways are involved in the genesis of these neoplasias and, in particular, it is very pr…
Linkage analysis in Usher syndrome type I (USH1) families from Spain.
1998
Usher syndrome (USH) is an autosomal recessive hereditary disorder characterised by congenital sensorineural hearing loss and gradual visual impairment secondary to retinitis pigmentosa (RP). The disorder is clinically and genetically heterogeneous. With regard to Usher type I (USH1), several subtypes have been described, the most frequent being USH1B located on chromosome 11q13.5. Of 18 USH1 families studied by linkage analysis, 12 (67%) showed significant lod score values for locus D11S527 (Zmax=14.032, theta=0.000) situated on chromosome 11q. Our findings suggest considerable genetic heterogeneity in the Spanish USH1 population. It is important to note that one of our families linked to …
Comparative architectural aspects of regions of conserved synteny on human chromosome 11p15.3 and mouse chromosome 7 (including genes WEE1 and LMO1)
2001
Human chromosome 11p15.3 is associated with chromosome aberrations in the Beckwith Wiedemann Syndrome and implicated in the pathogenesis of different tumor types including lung cancer and leukemias. To date, only single tumor-relevant genes with linkage to this region (e.g. LMO1) have been found suggesting that this region may harbor additional potential disease associated genes. Although this genomic area has been studied for years, the exact order of genes/chromosome markers between D11S572 and the WEE1 gene locus remained unclear. Using the FISH technique and PAC clones of the flanking markers we determined the order of the genomic markers. Based on these clones we established a PAC cont…
Role of the insulin-like growth factor system in adrenocortical growth control and carcinogenesis.
2004
Clinically silent adrenocortical adenomas are the most frequent abnormalities in the adrenal gland. In contrast, adrenocortical carcinoma is a rare tumor with an extremely poor prognosis. The factors responsible for the frequent occurrence of benign adrenocortical tumors on one hand and the rare malignant transformation on the other are not known. Several genetic alterations such as loss of imprinting or loss of heterozygosity of the 11p15 gene locus causing a strong IGF-II overexpression have been demonstrated in the majority of adrenocortical carcinomas. In addition to IGF-II overexpression, increased levels of the IGF-I-receptor and IGFBP-2 have been found in advanced human adrenocortica…
High-urgency kidney transplantation in the Eurotransplant Kidney Allocation System : success or waste of organs? The Eurotransplant 15-year all-centr…
2016
Item does not contain fulltext BACKGROUND: In the Eurotransplant Kidney Allocation System (ETKAS), transplant candidates can be considered for high-urgency (HU) status in case of life-threatening inability to undergo renal replacement therapy. Data on the outcomes of HU transplantation are sparse and the benefit is controversial. METHODS: We systematically analysed data from 898 ET HU kidney transplant recipients from 61 transplant centres between 1996 and 2010 and investigated the 5-year patient and graft outcomes and differences between relevant subgroups. RESULTS: Kidney recipients with an HU status were younger (median 43 versus 55 years) and spent less time on the waiting list compared…

Androgen hydroxylation catalysed by a cell line (SD1) that stably expresses rat hepatic cytochrome P-450 PB-4 (IIB1).
1989
Androgen hydroxylation catalysed by Chinese hamster fibroblast SD1 cells, which stably express cytochrome P-450 form PB-4, the rat P450IIB1 gene product, was assessed and compared to that catalysed by purified cytochrome P-450 PB-4 isolated from rat liver. SD1 cell homogenates catalysed the NADPH-dependent hydroxylation of androstenedione and testosterone with a regioselectivity very similar to that purified by P-450 PB-4 (16 beta-hydroxylation/16 alpha-hydroxylation = 6.0-6.8 for androstenedione; 16 beta/16 alpha = 0.9 for testosterone). Homogenates prepared from the parental cell line V79, which does not express detectable levels of P-450 PB-4 or any other cytochrome P-450, exhibited no a…
The damped harmonic oscillator in deformation quantization
2005
We propose a new approach to the quantization of the damped harmonic oscillator in the framework of deformation quantization. The quantization is performed in the Schr\"{o}dinger picture by a star-product induced by a modified "Poisson bracket". We determine the eigenstates in the damped regime and compute the transition probability between states of the undamped harmonic oscillator after the system was submitted to dissipation.
