We describe a procedure, RNAPol-ChIP, to measure actual transcriptional rate. It consists of the detection, by chromatin immunoprecipitation (ChIP), of RNA polymerase II within the coding region of genes. To do this, the DNA immunoprecipitated with polymerase antibodies is analysed by PCR, using an amplicon well within the coding region of the desired genes(More)
OBJECTIVES The prognosis of old or immunocompromised patients with refractory or relapsing diffuse large-cell lymphoma (DLCL) is very poor as the current standard of salvage therapy with autologous stem cell transplantation (ASCT) is not feasible for most of them. New active regimens with an acceptable toxicity profile are needed. We aim to report the(More)
BACKGROUND Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of aggressive lymphomas associated with poor prognosis with standard chemotherapy. Consolidation with autologous stem-cell transplantation (ASCT) may improve survival. We present 74 patients transplanted in first complete response (CR) from the Spanish Lymphoma and Autologous(More)
Genes constitute only a small portion of the total genome and precisely controlling their expression represents a substantial problem for their regulation. Furthermore, non-coding DNA, that contains introns repetitive elements and active transposable elements, demands effective mechanisms to silence it long-term. Cell differentiation and development are(More)
The relationships between genomic DNA cytosine methylation, histone H4 acetylation and bud dormancy in Castanea sativa are described. Acetylated H4 histone and genomic DNA methylation patterns showed opposite abundance patterns during bud set and bud burst. Increased and decreased methylation levels in the apical buds coincided with bud set and bud burst,(More)
BACKGROUND The diagnosis of IgE-mediated immediate reactions to penicillins can be supported by in vivo or in vitro tests using classical benzylpenicillin determinants. The wide variety of beta-lactams and the description of new specificities requires a re-evaluation of the different tests available. The objective was to evaluate the diagnostic capacity of(More)
Cytosolic extracts from the posterior adductor muscle of the bivalve mollusk Mytilus galloprovincialis contain significant amounts of both cGMP-binding and cGMP-stimulated protein kinase activities. However, photoaffinity labeling with 8-azido-[32P]cGMP revealed only a major cGMP-binding protein with an apparent molecular mass of 54 kDa (p54), lacking(More)
OBJECTIVE Retrospective data shows that peripheral T-cell lymphoma (PTCL) patients sensitive to conventional chemotherapy for aggressive lymphomas may respond better if this treatment is consolidated with frontline autologous stem cell transplantation (ASCT). Here, we present data from a prospective phase II trial of high-dose chemotherapy and ASCT as a(More)
BACKGROUND T-cell immunophenotype constitutes an unfavorable prognostic factor in aggressive non-Hodgkin's lymphomas. High-dose chemotherapy with autologous stem-cell rescue (HDC/ASCT) is the best salvage therapy for patients with aggressive B-cell lymphomas. However, results with this therapy in peripheral T-cell lymphoma (PTCL) are not well defined. (More)
