Interphase fluorescence in situ hybridization (FISH) studies of chromosomal region 13q14 were performed to investigate the incidence and clinical importance of deletions in multiple myeloma (MM). Monoallelic deletions of the retinoblastoma-1 (rb-1) gene and the D13S319 locus were observed in 48 of 104 patients (46.2%) and in 28 of 72 (38.9%) patients,(More)
In multiple myeloma (MM), previous studies showed that mutations of the p53 gene are rare events in patients with newly diagnosed disease, but it is not known whether deletions of p53 are of any significance in MM. To address this question, we used interphase fluorescence in situ hybridization (FISH) with a DNA probe specific for the p53 locus at 17p13 and(More)
Wolfram Syndrome is an autosomal recessive degenerative disorder of the neuroendocrine system. Diabetes mellitus is its lead symptom. Patients show mutations in the wolframin (WFS1) gene coding for a hydrophobic transmembrane protein of 890 amino acids. This protein was preliminarily localised in the endoplasmatic reticulum (ER) in cells of mice and rats.(More)
Radiotherapy is a powerful cure for several types of solid tumours, but its application is often limited because of severe side effects in individual patients. With the aim to find biomarkers capable of predicting normal tissue side reactions we analysed the radiation responses of cells from individual head and neck tumour and breast cancer patients of(More)
During secondary immunoglobulin (Ig) diversification in vertebrates, the sequence of the variable region of Ig genes may be altered by templated or non-templated mechanisms. In both cases, cytidine deamination by activation-induced cytidine deaminase (AID) in the transcribed Ig loci leads to DNA lesions, which are repaired by conservative homologous(More)
In this study we investigated the effects of short term (ST, 24 h, 100 mM NaCl) and long term (LT) salinity (4 weeks, NaCl increased weekly from 100 to 400 mM) on leaf abscisic acid (ABA), calmodulin (CaM) and activity of antioxidant enzymes (superoxide dismutase, SOD; peroxidase, POD) in 1-year-old seedlings of two mangrove species, Kandelia candel and(More)
In 14 patients with myeloproliferative disorders associated with thrombocytosis, neurological and neuropsychological function were monitored prior to therapy with recombinant human interferon alpha (rIFN; dose 25 mU/week; range 10-35 mU/week) and after 3, 6, 9, and 12 months of treatment. No overt neurological side effects were observed except 1 case of(More)
The lower thoracic and lumbar spine of patients with multiple myeloma was examined by magnetic resonance imaging (MRI), plain radiography, and bone scintigraphy. Three independent investigators evaluated the power of these diagnostic methods to detect bone lesions in 192 vertebrae from 18 patients and in 60 vertebrae from 7 controls. 41 foci with abnormal(More)
31 patients with thrombocytosis associated with myeloproliferative disorders were included in a prospective trial of long-term interferon therapy. 6 patients (19%) had side-effects which required withdrawal of interferon within one year. 22 patients (71%) achieved and maintained a complete response (platelet count less than 440 x 10(9)/l) for at least(More)
