Xenograft studies indicate that some solid tumors and leukemias are organized as cellular hierarchies sustained by cancer stem cells (CSCs). Despite the promise of the CSC model, its relevance in humans remains uncertain. Here we show that acute myeloid leukemia (AML) follows a CSC model on the basis of sorting multiple populations from each of 16 primary(More)
Patients with cytogenetically normal acute myeloid leukemia (CN-AML) show heterogeneous treatment outcomes. We used gene-expression profiling to develop a gene signature that predicts overall survival (OS) in CN-AML. Based on data from 163 patients treated in the German AMLCG 1999 trial and analyzed on oligonucleotide microarrays, we used supervised(More)
Waldenstrom's macroglobulinemia (WM) is very distinct from other indolent lymphoma subtypes: by definition it is accompanied by a monoclonal IgM gammopathy; it presents always with bone marrow infiltration and often with clinical symptoms such as neuropathy or hyperviscosity. These disease characteristics and the frequently advanced age of the WM patient(More)
These Clinical Practice Guidelines are endorsed by the Japanese Society of Medical Oncology (JSMO) incidence Waldenström's macroglobulinaemia (WM) is a rare disease. It accounts for 1%–2% of haematological neoplasms with a reported age-adjusted incidence rate of 3.4 per million among males and 1.7 per million among females in the United States and 7.3 and(More)
Recently, expression patterns of microRNAs in body fluids underscored their potential as noninvasive biomarkers for various diseases. Here we summarize the current works describing microRNAs in blood cells or serum as biomarkers and the applied methodologies of small RNA purification and detection. Future challenges and the required research relating to(More)
Activating mutations of the protein tyrosine kinase (PTK) FLT3 can be found in approximately 30% of patients with acute myeloid leukemia (AML), thereby representing the most frequent single genetic alteration in AML. These mutations occur in the juxtamembrane (FLT3 length mutations; FLT3-LMs) and the second tyrosine kinase domain of FLT3-TKD and confer(More)
High-dose therapy (HDT) followed by autologous transplantation of hematopoietic stem cells (ASCT) is frequently performed in patients with lymphoma. For many subentities, reliable results from prospective randomized studies are missing. In Hodgkin's disease (HD), HDT/ASCT is a standard indication for patients with chemosensitive first relapse. Patients with(More)
Chromosomal translocations generating fusion proteins are frequently found in human leukemias. The fusion proteins play an important role in leukemogenesis by subverting the function of one or both partner proteins. The leukemogenic CALM-AF10 fusion protein is capable of interacting with the histone H3 lysine 79 (H3K79)-specific methyltransferase hDOT1L(More)
Processing of pre-miRNA through Dicer1 generates an miRNA duplex that consists of an miRNA and miRNA* strand. Despite the general view that miRNA*s have no functional role, we further investigated miRNA* species in 10 deep-sequencing libraries from mouse and human tissue. Comparisons of miRNA/miRNA* ratios across the miRNA sequence libraries revealed that(More)
