Embryonal tumor with abundant neuropil and true rosettes (ETANTR) is a recently recognized, rare embryonal CNS tumor, which predominantly occurs in young children and is associated with a highly aggressive disease course [1–3, 5–8, 13, 14, 18, 19, 23]. The histopathological diagnosis of ETANTR is based on the presence of primitive neuroectodermal tumor(More)
AtUBC2 of Arabidopsis thaliana encodes a structural homolog of the RAD6 gene of Saccharomyces cerevisiae with approximately 65% identical amino acids. Like structural homologs from other organisms, AtUBC2 lacks the carboxyl-terminal extension of mostly acidic amino acids which is present in Rad6p. AtUBC2 was expressed in S. cerevisiae rad6 mutants. It was(More)
To assess the value of anti-isocitrate dehydrogenase 1 (IDH1) immunohistochemistry for evaluating diffuse gliomas, we analyzed anti-IDH1-R132H immunohistochemistry using monoclonal antibodies DIA-H09 and IMab-1 and IDH1 gene sequencing in formalin-fixed and paraffin-embedded biopsy samples of 95 diffuse gliomas. We found concordant immunostaining results(More)
BACKGROUND The interest in neonatal screening for lysosomal storage disorders has increased substantially because of newly developed enzyme replacement therapies, the need for early diagnosis, and technical advances. We tested for Gaucher's disease, Pompe's disease, Fabry's disease, and Niemann-Pick disease types A and B in an anonymous prospective(More)
PURPOSE ETV1 has been proposed to be activated by KIT mutations in gastrointestinal stromal tumors (GIST). The aim of the study was to evaluate the clinical role of ETV1 and associated proteins in GIST. EXPERIMENTAL DESIGN Expressions of ETV1, MAPKAP kinase 2 (MAPKAPK2), phosphorylated p38 MAP kinase (pp38), phosphorylated MSK1 (pMSK1), phosphorylated(More)
The gene PRT1 of Arabidopsis, encoding a 45-kD protein with two RING finger domains, is essential for the degradation of F-dihydrofolate reductase, a model substrate of the N-end rule pathway of protein degradation. We have determined the function of PRT1 by expression in yeast (Saccharomyces cerevisiae). PRT1 can act as a ubiquitin protein ligase in the(More)
OBJECTIVE To evaluate the use of microarray analysis as a tool for the detection of submicroscopic chromosomal aberrations in prenatal diagnosis. METHODS Twelve consecutive singleton fetuses with congenital heart defects but normal karyotype and normal fluorescence in situ hybridization results for the DiGeorge region were examined for chromosomal(More)
OBJECTIVE To evaluate global and single gene methylation patterns as a sign for epigenetic modulation of the immune system in infants born by elective cesarean section (CS) and vaginal delivery (VD). STUDY DESIGN For this prospective pilot study a two step approach was chosen. Initially 41 newborn infants comprising 23 delivered by VD and 18 delivered by(More)
OBJECTIVE To investigate the association between two genetic variations in the Interleukin-1 beta (IL1B) gene and preterm birth. STUDY DESIGN In this case-control study we tested the allelic distribution of two of its common polymorphisms (IL1B +3953C>T [rs1143634], IL1B -511C>T [rs16944]) in one hundred women with preterm birth and one hundred healthy(More)
Nodal marginal zone lymphoma (NMZL) is a primary nodal B-cell lymphoma that shares morphological and immunophenotypic characteristics with extranodal and splenic marginal zone lymphoma. Data on altered genes and signaling pathways are scarce in this rare tumor entity. To gain further insights into the genetic background of NMZL, seven cases were(More)
